The Review
Feedback summary: 

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.

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.

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. 

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.
