A2B Direct Image

A2B Direct

A2B Direct is a logistic B2B marketplace that connects cargo owners (customers) and freight forwarders (carriers). It’s often labeled as “Uber” for cargo transportations on the web.

Overview

Initially, A2B Direct had a basic functionality that included only a possibility to book forwarders and give them ratings. However, after some testing, it appears that more sophisticated features are required

for the platform to work effectively. Limestone Digital was responsible for delivering some ports of the extensive functionality of this platform.

Challenge

A challenge here was to create a system that would be able to communicate effectively with multiple third-party service providers. Considering the amount of data needed to processed, it was particularly important to create a system that would be extremely resilient.

Solution

To tackle the challenges, the decision was made to focus on three main areas. First of all, the system needed a great variety of algorithms on the backend to create different scenarios and features. Secondly, it’s needed to create different user roles (customer, carrier, and admin) so that different users can have access to different platform features. And finally, for those features to function, the system needed a durable architecture.

Powered by Toco Image

Powered by Toco

Powered by Toco is an affiliate platform where Toco Warranty's partners can register as affiliates and sell their warranties for auto repair coverage.

Overview

The concept of a referral program first came to be when Toco Warranty, a provider of vehicle service contracts for auto repair coverage, realized how beneficial that could be for their business. Limestone Digital team quickly accessed the

idea and suggested creating an affiliate platform where the users (affiliates) can take ownership over and be proactive about the selling of warranties.

Challenge

When faced with the business growth concerns of Toco Warranty, Limestone Digital quickly realized that a system they were about to build had also to be very secure. The very fact that people shared through the platform sensitive information to create their accounts implied a greater level of privacy and security that needed to be provided.

Solution

The team at Limestone Digital built a software application that is able to accomplish all the required objectives. Although the project is still ongoing, Toco Warranty has already had a chance to highly appreciate all the benefits that Powered by Toco has provided to their business.

mBanc Image

mBanc

mBanc is a non-qualified loan provider that can help provide a loan, basing on alternatives methods, in case someone doesn't qualify for a traditional one.

Overview

To get a loan from mBanc, an application must be filled out online. Millions of applications need to be processed each month. Because of this, mBanc needed a system that would be able to automate the application

process.

Challenge

The team first worked to rebuild the landing pages. Then they moved on to the biggest concern: decrease the amount of manual work and increase the mBanc’s capacity to process online applications.

Solution

Limestone Digital automated the process by designing a questionnaire an applicant must fill out to see the kind of loans they qualify for. Once done the applicant is provided with loan rates calculated by using the information they gave.

Feedback summary: 

Throughout the partnership, Limestone Digital has been able to find creative solutions for complex, technical problems. In addition to being organized and proactive, the team always completes tasks and delivers work on time. Additionally, they offer valuable technical and strategic suggestions.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the head of engineering at a startup. Our platform directly connects cargo owners with transportation companies and lets them make a deal without any intermediaries.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Limestone Digital?

We started the step of scaling about two years ago. When we completed the round of attracting investors, we wanted to scale quickly. However, our ability to hire our own engineering personnel was limited by classical marketing constraints. 

This meant that we couldn’t grow as quickly as we wanted to. We had a very high and specific demand for growing our platform much quicker than we could hire developers. So, we turned to Limestone Digital because they had experience in the logistics industry and working with transportation projects.

SOLUTION

What was the scope of their involvement?

They helped us to scale our team, working as an extension of our team. They work remotely but they serve as an integral part of our engineering department. We work in Java and our project is mostly microservices-based. 

Limestone Digital supports certain microservices, and we focus on others. The team is doing on-request calculations working with different technologies. 

For the frontend, they work with Angular. Limestone Digital also helped us to transfer to the latest version.

What is the team composition?

We work with front- and backend developers, as well as a business analyst and a delivery manager. Over the course of the project we’ve worked with between 12–15 teammates. 

How did you come to work with Limestone Digital?

We researched different companies that had expertise in this domain. We then partnered with a number of companies in the initial stages, including Limestone Digital. They were able to prove their qualification in the sector by demonstrating a number of projects they worked on and describing their architecture. 

By analyzing the solutions they developed, we were able to make a confident decision that they were a good fit. They provided case-based proof of their qualifications on the technical side. We stopped working with the other companies and replaced them with our in-house developers, but our relationship with Limestone Digital was strong. 

How much have you invested with them?

So far, we’ve spent $400,00–$500,000.

What is the status of this engagement?

We began working with them more than a year ago, in about December 2018. We are still working with them.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

There were a number of technical problems that we had to tackle, but Limestone Digital has a very strong ability to tackle problems from various angles, making them an invaluable partner.

When we had complex technical requests from our clients for which we couldn’t find a solution, Limestone Digital helped us figure out a creative approach to tackle this technical problem while helping us with the user-flow perspective.

How did Limestone Digital perform from a project management standpoint?

The team is very organized, always delivers on time, and reacts proactively to issues. Additionally, they are very accommodating whenever we need something extra that is in addition to our regular workload. 

What did you find most impressive about them?

They were able to not only bring technical expertise but also to suggest specific approaches on how to operate and scale the platform that we were trying to grow. Everything they do on the analytical, managerial, and technical sides, is in sync. They match our level of expertise.

Are there any areas they could improve?

No, I have no suggestions. I have an overall positive impression of them as a partner.

BACKGROUND

Introduce your business and what you do there.

I’m the CEO of Engenious, an app development company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Limestone Digital?

We had some projects that required a larger team than the number of resources we had available. We were working with a client that provides a variety of services for VPN solutions.

SOLUTION

What was the scope of their involvement?

We put three Wi-Fi routers in-house and wrote scripts. Those scripts turned on different routers and we forced the VPN connection to open and close tunnels between mobile clients. We delivered several mobile apps as well. Their work was done completely remotely.

What is the team composition?

There were two iOS developers, two Android developers, one backend developer, one frontend developer, and one project manager.

How did you come to work with Limestone Digital?

I met the director of sales at a conference and felt they’d be a good team to partner with.

How much have you invested with them?

We’ve invested about $300,000.

What is the status of this engagement?

We started working together in February 2019, and the work is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We’re satisfied with the KPIs. They work alongside our team. Our in-house people are really happy with the collaboration. There’s always a team working because we are in different time zones, and it’s comfortable for everyone.

How did Limestone Digital perform from a project management standpoint?

Their project manager helped us to manage all the KPIs and deliverables in Jira. The project manager is great. He manages the team well and makes sure all the deliverables are achieved. I don’t recall any conflicts with them or deadlines having to be moved. Their organization is high-level. We communicate via Slack.

What did you find most impressive about them?

I enjoyed their organizational skills. The project manager keeps everything organized. They know exactly how to manage development pipelines. They control the whole team, including our programmers’ overall deliverables. They know exactly how to build the process so the development is faster. The coding is great.

Are there any areas they could improve?

We want more people on the team. They agreed to expand the team soon.

Do you have any advice for potential customers?

Make sure you describe the project well. They have business analysts that help to transform your idea into an executable plan. I recommend you take advantage of their knowledge.

BACKGROUND

Please describe your company and your position there.

Research IP Design Ltd is the company responsible for the architecture and management of the software development of the Nexus platform and product. Nexus is a bespoke system that enables advertising and media companies to better control their financial administration, and operational management tasks.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Limestone Digital?

We needed to expedite the creation of a media planning and buying feature that would vastly improve the capture and management of media placements.

What were your goals for this project?

To create a new web based media planning grid using Vue & Typescript as well as the required supplementation configuration and detail pages.

SOLUTION

How did you select this vendor?

We were looking to outsource the development and after previous failed attempts making use of developers from other territories we explored making use of eastern European developers. Search results showed Limestone had high ratings from their existing clients, so we made contact hoping to put their skills to the test.

Describe the project and the services they provided in detail.

They interpreted and developed to spec a new front-end placement management portal. The project began with a technical vetting process, followed by project run through via video call. Once the project was initiated I spent some time at their offices in Kiyv to familiarise the team with the requirements and strategise implementation of components. Once started we continued with daily remote stand-ups and bi-weekly presentation of progress to the project stakeholders. Implementation was prompt and the developers were highly vested in the success of the project as well as the quality and maintainability of the software.

What was the team composition?

The project team had 4 people, myself as the technical coordinator of the implementation. Limestone supplied two developers, one front and one back-end developer as well as a project manager that would aid in communication when required

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

The project sped up the delivery of the feature by roughly 2 man months and we were able to use the feature immediately as example implementation for future projects as well as demo-able POC to client.

How was project management arranged and how effective was it?

Project management was mostly coordinated by myself as this was the arrangement from the onset. External project management was facilitated by Limestone to aid internal communication and planning

What did you find most impressive about this company?

Their commitment to the success of the project. They are enthusiastic and focused on adhering to coding best practices. Mark has a hands-on approach to ensure his staff are contributing to client expectation, and open to hear about possible improvements.

Are there any areas for improvement?

None at present.

RESULTS & FEEDBACK

The projects managed and products delivered by Limestone Digital exceed expectations every single time. They save time for their clients and develop their team’s skills to meet changing project needs. Their team stays on schedule and takes responsibility for their own process throughout the work.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the president of a software platform in the e-sports world. We have an e-sports platform that’s used by schools and organizations for whom we develop our own software.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Limestone Digital?

Our biggest challenge is that it is difficult to maintain a medium to large development team employing fully on-shore developers. Limestone Digital allows us to support our US-based team with Limestone Digital’s resources overseas.

SOLUTION

What was the scope of their involvement?

In general, Limestone Digital works together with our US office and provides several layers of resources. They actually handle both project management and product management services. One side of that is to help keep projects on task, and the other is that they’re also very good at maintaining product integrity.

Their work covers pretty much any relevant technology you can think of, whether that’s CSS, HTML, AngularJS, React frontend, Java, PSP, or anything else. Through those two components, they provide both frontend and backend development resources that work in conjunction with our team.

The platform itself is obviously a very large scope, so certain components are typically assigned to their team, and they’re able to see those components from beginning to end. They’re involved in the planning and execution, the QA, and then ultimately in delivering that component to us.

What is the team composition?

We work with about 10 people from their team.

How did you come to work with Limestone Digital?

They were referred to us by an industry colleague.

How much have you invested with them?

We’ve probably spent around $500,000–$600,000 in total

What is the status of this engagement?

We began working together in mid-2016 and our partnership is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Limestone Digital’s work saves our company a lot of time and allows us to roll out features much faster. We are always able to trust the quality and timing of their components, which frees us up to focus more intently on the parts of our projects assigned to our US teams and increases the quality of all of our work.

How did Limestone Digital perform from a project management standpoint?

When we hand them a project, they will break a large task into weekly sprints with their own defined deliverables on their own. Then they will take your English API documentation and produce that documentation from back to front, and exactly on schedule. Having two designated people—one who understands the product in and out, and another who is actually managing the project—allows for that level of coordination and reliability.

Their method of organizing their staff is also really effective. A lot of times, what happens behind the scenes overseas can be a bit of a mystery, but with Limestone Digital, they’ll either recruit from the outside or from within and assign people that are dedicated to your project. Over time you form a relationship with all the people on your team and can work with their strengths and weaknesses the same way you would in-house.

What did you find most impressive about them?

The biggest thing is just that they can take a large component and break it down into very defined objectives that they then deliver on time. Having worked with so many companies, I can tell you that you just don’t get that with other teams. That’s what everybody’s missing and it’s what they do best.

Are there any areas they could improve?

They’re great and they’re so reasonably priced, there’s really nothing I could pinpoint that they could improve.

Do you have any advice for potential customers?

I think this applies to any time you’re taking a project to a development house, but people have different levels of risk tolerance. There are people who prefer that the development team ask a lot of questions before making decisions on their own, and people who prefer they just figure things out and come back with a solution. It’s important that the style you prefer is communicated at the beginning of the project and on a regular basis throughout the work.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I'm the director of operations at Toco Warranty. We sell vehicle service contracts to consumers. We do a lot of our sales in-house, but we also have an e-commerce funnel. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Limestone Digital?

We wanted to generate more leads through our website, so we needed a vendor to help us with our website and internal Salesforce development. We went through many different companies, but we still had ongoing issues and bugs. We were looking for a new company to work with us.

SOLUTION

What was the scope of their involvement?

Our customers were receiving unnecessary pop-up messages because of the technical issues we were having on the backend, which stopped them in the middle of a sales process. Limestone Digital cleared out the bugs that were causing those pop-ups, so now our customers can proceed all the way through the funnel to purchase. They also fixed the quote retrieval process, enabling our customers to come back and retrieve the information they need. In addition, Limestone Digital helped us with our vendor management and lead tracking. 

We have a lot of ongoing projects at any time. They also handle the website design and write press releases for us. If I have a request, I fill out the details, attach a screenshot, and send everything to them. Almost  immediately, I get a confirmation email saying that it's been scheduled and added to the devs scope of work.

What is the team composition? 

We work with a project manager and 3–4 other members of their team.

How did you come to work with Limestone Digital?

They were recommended to us. 

How much have you invested with them?

We pay them about $10,000–$15,000 a month.

What is the status of this engagement? 

We started working with them in March 2019 and the relationship is ongoing. 

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

Within the first 60 days of us working together, Limestone Digital resolved about 75% of all the issues we had been experiencing for years. Our conversion rate and our sales have skyrocketed. Our website also loads much faster. We can set up promo codes ourselves and schedule them for weeks in advance. People really want to take advantage of those promo codes, so that helped us boost our sales. 

How did Limestone Digital perform from a project management standpoint? 

They understand exactly what I ask of them, but they're also available to hop on the phone call when needed. If they know of a better way to do things, they'll always make suggestions, which we find invaluable. We mostly use Write to keep track of the project. 

What did you find most impressive about them?

They're very knowledgeable and have been able to guide us in the right direction. They're really focused on making us happy and work long hours to make sure they meet our needs.  

Are there any areas they could improve?

I can’t think of anything.

Do you have any advice for potential customers?

They're very responsive, but it helps to plan things out, especially if you're in different time zones.

The platform has generated positive feedback from early users. The team brings expertise and accountability to an engagement that remains within budget. Strong project management skills include problem solving and punctuality.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I am the acting CEO of an event management software firm. We market our products to event managers. Our software supports reservations, seating, and other such functions.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Limestone Digital?

I needed to outsource additional software development for our web platform.

SOLUTION

What was the scope of their involvement?

They are building a reservation system that enables customers to arrange pricing based on chosen parameters. They developed a portal so customers can run reports on their data. We can email marketing material through the SendGrid connection they built into the platform. Customers can also arrange event seating through another portal.

What is the team composition?

I interact daily with the project manager and regularly work with a backend web developer, a frontend developer, and an Android developer.

How did you come to work with Limestone Digital?

I know the owner of Limestone Digital. I was involved in another project they worked on and was happy with the results.

How much have you invested with them?

We have spent $50,000—­$200,000.

What is the status of this engagement?

The project began in November 2017 and the partnership is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

They meet our needs in a timely manner. Whenever we’ve had an issue with a developer underperforming, they’ve informed me immediately. We are still in development, but we have some customers using the system already and they are very happy with it.

How did Limestone Digital perform from a project management standpoint?

The project manager is very understanding and good at what he does. He delegates assignments to their developers and makes sure tasks are done efficiently. We communicate on the phone and use Clubhouse project management software to track the project.

What did you find most impressive about them?

They proactively monitor their team’s work and identify and address issues as soon as they arise. In particular, my relationship with the project manager is more effective than anything I’ve experienced with previous vendors.

Are there any areas they could improve?

We did experience some issues early in the engagement, but we’ve resolved them and I can’t think of any shortcomings now.

Do you have any advice for potential customers?

Clients should be open about issues and address them with the vendor immediately. Waiting too long into the process will lead to an unsatisfactory result.

The Review
Feedback summary: 

Limestone Digital expanded the platform’s capabilities, enhancing both its data analysis and visualization features. Users can now track data in real time and review information through different parameters. The team was receptive to feedback and communicated consistently throughout the engagement.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I’m the head of R&D at Vienna Water Monitoring Solutions (VWMS) GmBH. We’re an Austrian company that develops and produces a line of devices called the ColiMinder series. With our products, users can automatically monitor microbial water contamination online for different organisms.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Limestone Digital?

We needed IT specialists to further develop a database-driven IoT platform (Big Data). The platform connects with our devices to visualize and analyze contamination measurements, track errors, and notify customers.

What were your goals for this project?

Our objective was to have an installable, centralized/decentralized server-client web app that could query live and historical data in real time. We also wanted the app to have a responsive design.

SOLUTION

How did you select this vendor?

We held an online video conference with Limestone Digital to evaluate their development team’s capabilities. We concluded that they understood the tasks at hand and had all the necessary resources to handle implementation.

Can you go into detail about the services they provided and the scope of the project?

They first tackled the UX design, making modifications based on our feedback. Next, they used our technical requirements and documentation to develop the front- and backend. As the project progressed, we introduced new ideas, which they were happy to accommodate. They currently continue to provide ongoing maintenance and support.

What was the team composition?

They assigned a relatively small team consisting of a UX designer as well as front- and backend developers.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

Limestone Digital implemented new features into our platform, which has enabled us to get more detailed information from our devices. We can now analyze the data using additional conditional parameters.

How was project management arranged and how effective was it?

We discussed each step of the development in detail through Slack and Google Hangouts. They also used Google Docs and Sheets to send daily activity reports from the developers as well as monthly progress reports.

What did you find most impressive about this company?

They’re a young, creative-minded team that works quickly. Furthermore, I appreciate their in-depth understanding of our needs.

Are there any areas where they can improve?

It may benefit them to make some minor improvements on how they prepare business proposals.

The Review
Feedback summary: 

By working long hours and communicating every day, Limestone Digital delivers exceptional results. The agency streamlines the delivery process, allocating staff efficiently and emphasizing tangible results. Their quick turnaround times and business sense make them an outstanding resource. 

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I am the co-founder of a health and beauty company. I primarily lead the technology portion of our business operations.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Limestone Digital?

Our business plan focused on an outsourced technology model. We were looking for a firm that could help us achieve that.

SOLUTION

What was the scope of their involvement?

Our entire technology operation is currently run in partnership with Limestone Digital. They do everything, including the website, the backend systems, and the operational software. The only internal technology person is me.

They primarily do full-stack development using C#. They are covering everything, which I am really excited about.

What is the team composition?

Around 12 people from their team work on the project, and we work directly with the project manager and developers.

How did you come to work with Limestone Digital?

Their founder worked for me directly at one point, so we became his client when he started the company.

How much have you invested in them?

We have invested more than $200,000 so far.

What is the status of this engagement?

We started working with them in January 2016 and the work is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Their team is extremely dedicated. They overcame the time zone issue by working late when necessary. Among development firms, their process is unique. In addition to a project manager, they have a delivery officer who is focused on delivering results.

We work at a startup speed with agile, quick turnarounds. They are capable of working within that environment and turning things around very quickly. They understand the business side and get us what we need. That flow works very well.

How did Limestone Digital perform from a project management standpoint?

They do an amazing job. We use Wrike for project management, but we speak to them all the time. We communicate through GitLab, Wrike, email and maybe Slack. We talk to a broad range of people on their side, some of them daily. Other people in the company are not directly involved with our project but help with HR issues and hiring.

What did you find most impressive about them?

Their vision is extremely unique. They are not just there to sell seats to developers and make money. They choose their clients very specifically. They only want to work with clients that know what they want, and that have very strong business goals that parallel their technology and product goals. As long as the business can maintain that communication, the delivery lifecycle is amazing.

Do you have any advice for potential customers?

To get the best out of them, you must demand the best from yourself. If you can demand from yourself that same discipline and deep understanding of your needs, you will get it from them as well.
