Using the demo version as a starting point, InventorSoft is further developing a Java-based web platform, providing front- and backend development and web design services.
Despite the constantly shifting requirements and a dynamic schedule, InventorSoft has adapted well to client needs. They’re quick to supply relevant resources and execute instructions well. Although stronger English skills would facilitate communication, they remain attentive and well-organized.
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 co-founder and CTO of an early-stage startup called YardSignNetwork. We’re building an advertising network for the real estate industry.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with InventorSoft?
We had already developed a demo version of our web platform along with some of the core features but lacked the engineers to continue development. So, we needed a flexible service provider that could help us further develop our web platform. The team had to include front- and backend developers as well as a web designer who understood usability.
SOLUTION
What was the scope of their involvement?
InventorSoft provides ongoing development services to further build out our web platform. Since we’re operating on a fairly new business model, things change often, and we have to adapt accordingly. As a result, it’s hard for us to plan how many hours and resources we need beyond two-week sprints.
I typically write the specs documentation for each sprint, which they break down into tasks and deliverables. The team works with Java frameworks on the server side, including Spring and Hibernate, and a MySQL database for the backend. On the frontend, they use Angular.js.
What is the team composition?
We currently work with a backend developer, a frontend developer, and an HTML designer. The CTO serves as our main point of contact.
How did you come to work with InventorSoft?
I searched for small- to medium-sized outsourcing companies and shortlisted about a dozen. After working with two other vendors, I stumbled upon InventorSoft, which worked well for us. They were flexible with our schedule had a pool of talented engineers.
How much have you invested with them?
We spend about $4,000 a month with them, which amounts to $250,000 so far.
What is the status of this engagement?
Their work started in August 2018 and is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
As an emerging startup, it’s important for us to work with a team that can accommodate a dynamic schedule, and InventorSoft has been the perfect fit. They’re by far the best company we’ve contracted. We’ve hit some unforeseen hurdles here and there, but that’s to be expected. Even in those cases, their team strove to deliver within a reasonable timeframe.
How did InventorSoft perform from a project management standpoint?
We coordinate with them using our project management software, but I don’t think they need management. They keep on task, which allows me to continue working on my end. In terms of communication, they respond relatively quickly despite the time difference.
What did you find most impressive about them?
I’m impressed by a number of their qualities. Not only are their prices fair, but they’re also able to adapt to short-term changes. Their team consists of qualified specialists who are available when needed.
Are there any areas they could improve?
It would be helpful if they had engineers with higher English proficiency. There have been times when they’ve asked a question, and I’d have to ask them to explain it 2–3 times before I could understand. Investing in higher English skills would also make it easier to communicate with the rest of my team.
Do you have any advice for potential customers?
Many of my colleagues outsource projects for third-party clients to external vendors. But these clients have their own requirements and will get frustrated when things aren’t done a certain way. In those cases, it’s best to plan ahead and prepare for this. Take the time to create a roadmap, outlining all of the development stages with InventorSoft to avoid any missteps.

client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the CEO of a telecom analytics startup. We develop solutions for mobile operators that help them understand and improve their metrics. We also provide a metric guide that targets end users.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with InventorSoft?
We needed an experienced development firm to build out some software modules within our solution.
SOLUTION
What was the scope of their involvement?
We started our engagement with InventorSoft by communicating the project’s requirements. Utilizing an agile approach, they further refined the project’s scope of work. We didn’t put a lot of effort into providing detailed specifications because wanted a quick development cycle. Additionally, we weren’t 100% sure how we wanted the solution to work. Our vision became more distinct as the project progressed.
InventorSoft created supplemental software modules that support our solution’s system. They also helped build the backend architecture of our iOS and Android applications. Their team uses Java, MySQL, and other products within the Google Cloud suite to accomplish each assignment.
What is the team composition?
We interact with four resources from their team.
How did you come to work with InventorSoft?
They were recommended to us by a development company we worked with previously.
How much have you invested with them?
We’ve spent around $30,000 thus far.
What is the status of this engagement?
We started working together in May 2018, and the work is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
InvesterSoft does an excellent job at everything we ask. Their CEO is exceptionally pragmatic and helpful. He has strong technical skills and puts the time in to ensure each collaboration goes smoothly. We’re happy with their work.
How did InventorSoft perform from a project management standpoint?
Our internal staff handles most of the project management responsibilities involved with this engagement. However, we interact with their developers and CEO quite often. They consistently deliver products within established timelines. We have daily meetings with them over Skype, and we use email to communicate.
What did you find most impressive about them?
InvestorSoft provides quality work that reflects their asking price. We appreciate their CEO’s involvement in each undertaking.
Are there any areas they could improve?
The only challenge we’ve faced while working with them relates to the language barrier. The CEO is perfectly fluent in English, but some of the developers need extra time when communicating in written English.

BACKGROUND
Introduce your business and what you do there.
We have two businesses and a startup project still in the building phase. Our software build company is called Software Research, and the operational one is Calculus Solutions. We're building an automated real-time financial trading system. I'm the CTO of the group.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with InventorSoft?
We were building a relatively complex piece of software and didn’t want to hire people in-house. We wanted to outsource the work and reached out to a few companies.
SOLUTION
What was the scope of their involvement?
They provided development services. They’ve also had a role to play during the actual launch and operational/maintenance mode.
The platform has a service-oriented architecture with multiple components spanning several servers. There are a few microservices included, and everything has to work in a real-time mode. We based the whole thing on Java 8, Spring Boot, and that whole family. All the servers are Linux-based.
InventorSoft had in-house front- and backend UI capabilities. We used their services for the infrastructure development, engine-room algorithmic work, the UI surface piece, and the immediate UI backend shim sitting between the frontend and the engine room.
What is the team composition?
We've had four or five people onboard, on average: two UI designers and three backend deep algorithm specialists.
How did you come to work with InventorSoft?
We found a number of agency candidates on Upwork, including InventorSoft. We had a number of interactions and did some small, test implementations before we made our final choice.
What is the status of this engagement?
We started working with them in the summer of 2017. We will probably sign a contract for ongoing maintenance and further feature development.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
They were able to cover the full scope, which we were quite pleased with. It isn’t an easy task to find this kind of scope coverage, in terms of technology stack and expertise.
They're an open and friendly team with good language skills. We found them to be extremely professional. They have top-notch offices and ongoing in-house training programs—both technical training and language upgrades. I'm very satisfied.
How did InventorSoft perform from a project management standpoint?
A colleague and I have visited their Ukraine office in order to work side-by-side during a two-week period. I found it to be an important team-building exercise for getting to know each other better, given that this was a long-term engagement from both our sides.
I'm never satisfied in terms of deadlines—it's never fast or good enough for me, but they don’t mind coming and putting in an extra couple of hours on the weekend. I’m quite happy with the velocity and the output quality, and the engagement itself, in terms of interactions and finding the right solution. They're good at keeping deadlines, although we don’t have many of them.
Are there any areas they could improve?
Internet quality is one of the critiques and points of irritation we’ve had for quite some time. This is not necessarily their fault, but we’ve spoken quite a bit about it. We need a lot of telecommunication, in terms of screen sharing and video, and this requires some serious bandwidth and reliable internet connectivity. It didn’t work well in the beginning, and we still have some steps to take. Too often, the sound quality isn't good enough and we can’t have video at the same time as voice and screen sharing due to the bandwidth.

What is the team composition?
I work with a project manager and three developers.

BACKGROUND
Introduce your business and what you do there.
I’m a project manager for an event services company.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with InventorSoft?
Our main business is a chauffeur service, which gave us the idea to create our own rental car platform. We needed help building our web app.
SOLUTION
What was the scope of their involvement?
They helped us build our consumer-facing solution. We used the newest technologies for front- and backend development.
What is the team composition?
They have a back- and frontend developer and we provided the software architect, web designer and project manager.
How did you come to work with InventorSoft?
We found them through an online search. We tried several options, and considered giving the full project to a company in Germany, but it turned out to be more complicated and expensive than we expected. We decided on the scope with two other companies in Germany, but we decided not to work with them either. Our next approach was to do in-house development. We partly worked with in-house developers, but we needed more people. Our architect then checked if InventorSoft had enough knowledge to be able to work on this project.
How much have you invested with them?
We pay a monthly price.
What is the status of this engagement?
We started working together in August 2017 and the work is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
They have been very committed and so far we have always achieved our internal deadlines with them.
We invited the backend developer to stay with us for a week to work with our team and it was very successful. It was great for the whole team to have him here in our office. They don’t feel like an external company; the developers feel like they’re part of our company. We all work with the same goal and vision. It keeps team spirit high.
How did InventorSoft perform from a project management standpoint?
It’s a very dynamic project. The weekly meetings we have with them are pretty easygoing. They understand what we need and they adapt to our agile approach.
Our architect guides the developers, if there are any general topics or questions, I contact the owner of Inventorsoft and he responds immediately. They’re always available and quick to reply. We communicate over Skype and can contact each other at any time. They deliver tasks on time.
What did you find most impressive about them?
I like that they’re a young team. They’re very motivated, knowledgeable and eager to learn.

I didn’t really consider other companies. I already had a developer working on the backend for the online platform before I contacted InventorSoft. I found them them through Upwork.

What is the status of this engagement?

InventorSoft developed a software platform that provides analytics to pharmaceutical companies. The engagement extended to include ongoing maintenance and development of additional software products.
Other companies estimated a 6–24 month development process, but InventorSoft delivered a finished product in 3 months. The new platform increased the client’s customer base exponentially, and now includes pillars of industry. Their development team is motivated by passion.
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 a Cofounder of a pharmaceutical analytics company. We offer SaaS products, our biggest being a social analytics product utilized by pharmaceutical companies.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with InventorSoft?
Initially, we tried to build the software with our own developers. After 2 years of time and money, all we had was a blob of useless code. We wanted to rebuild the platform with a different team. We reached out to InventorSoft in search of quality developers that could do so.
SOLUTION
What was the scope of their involvement?
They completed the monumental task of building out everything on our flagship platform. To do this, they used open source technologies like JavaScript, Angular, and a Postgres back-end. Everything was built on Google Cloud with OAuth 2.0 used for authentication. With our engagement extended, they upgrade and perform ongoing maintenance to the platform. They’re currently building more software products for us.
What is the team dynamic?
I functioned as the development lead, but InventorSoft’s founder was the project lead on their side who I worked closely with. The team size was 10–12 depending on the UX resources we needed to pull in. Specifically, we had 3 front-end and 6 back-end developers, respectively. There was also a UI/UX designer. They really are a full-stack platform development shop from planning to execution.
How did you come to work with InventorSoft?
We found them through a personal reference. Cost efficiency, speed of execution, and quality were important factors to us. We considered other vendors that were cheaper, but the quality suffered. Despite their marginally higher prices, InventorSoft made a compelling argument and we went with them.
How much have you invested with them?
The developers were paid $15-$25 an hour and would work 80-100 hour weeks during the initial development phase. The owner was flexible with our budgetary constraints. For an overall range, I’ll say $200,000+ over the course of the relationship.
What is the status of this engagement?
We started working together in July 2016, and the relationship is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Our business has exploded after we launched the platform. We went from 1 or 2 clients to 25 enterprise customers. The quality of code InventorSoft writes is comparable to code written by Google.
How did InventorSoft perform from a project management standpoint?
Their productivity is excellent. Other companies gave us estimates of 6–24 months to complete the platform. Those estimates were blown away when this team delivered the product in 12 weeks. Their responsiveness is phenomenal and the CEO is always available. It’s like they’re an extension of my team instead of a separate agency.
What did you find most impressive about them?
Their commitment and quality of engineers set them apart. I've visited InventorSoft’s headquarters and what I found is that they’re not just running an offshore company. They’re bringing like-minded people together and building an environment for these developers to thrive. They seek out people with a certain character. People who are motivated by quality of work and challenge, rather than pure monetary rewards. The team is young, and they bring a never-give-up attitude to each project.

InventorSoft took over software development after a previous vendor failed to deliver, fixing bugs without having to start over from scratch. They’ve even handled server tasks and QA for this ongoing project.
With the platform still being built, InventorSoft has been personally invested and goes above and beyond to deliver a satisfactory product, even granting direct access to the developers. They’re good at project management despite working with a highly customized software prone to causing delays.
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 founder of a company started based on an idea that I had 2 years ago for creating productivity software which, even though had alternatives, was divided into several platforms. We are putting together a universal solution, gathering together all other platforms in one place. The solution consists of email, calendar, invoicing, and business management components — everything you would want from a single user interface. The company is based in Estonia, but I am Swedish myself.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with InventorSoft?
I had been working with a Russian team and had spent about $25,000. I wasn’t happy with what I received and didn’t feel that the company valued my money and business. I was looking for someone who could take over the project and make sure that the work which had been done before wouldn’t be affected.
SOLUTION
What was the scope of their involvement?
I had the choice of either starting from scratch or finding someone who was good enough to deal with what had been done previously. I tried several companies and people; some of them gave up, but I was lucky to find InventorSoft. They spent some time on the project and ultimately said they could work on it.
It took InventorSoft a month to get started, fix some bugs and issues, and continue the project. We used the Java Spring Framework; the platform involves some encryption.
What is the team dynamic?
The collaboration with them is a completely different experience compared to my previous team, where I only had contact with the project manager and not the developers. InventorSoft gave me access to all the developers so that I could talk to them directly.
We initially had 2 developers working on the project, including a lead one. We now have a third one and a QA [quality assurance] beta tester. There are 4 people involved in total besides the owner of the company.
The Russian team had pretty much failed on all points. Even though they were a top-rated company on Upwork, they only cared about payments. There were constant delays and they couldn’t keep up with the work. Working with InventorSoft is completely different; I simply tell them what I want to do and they give me an estimate.
How did you come to work with InventorSoft?
I found InventorSoft on Upwork, the same as the Russian company. They made an offer I couldn’t refuse — to do all the initial work and get the project up-and-running to standard for only $1 per hour, in order to show me that they could do the work.
They spent over a month digging into the code, fixing all the bugs and issues and redeploying the project on a new server. I could see that they could handle themselves so I offered InventorSoft a better payment later on.
How much have you invested with them?
The cost has come to around $25,000. I think that the total will come to $50,000 within 6–7 months. We’re about to launch, and as soon as this happens, there will be more work and maybe even an extra developer.
What is the status of this engagement?
I started working with InventorSoft in January 2017 with 2 full-time developers from the start. We currently have 3, plus the QA assistant. They will be busy for at least 6–12 more months.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
I’m pretty excited about the project. InventorSoft’s team is comprised of good people that really try to deliver. Instead of the job being a source of payment, they treat it as a personal project.
One of the developers hurt her leg playing frisbee this week, and the lead developer apologized profusely for this and promised to do extra work.
How did InventorSoft perform from a project management standpoint?
They’re good in this respect. Since we have a custom project, it’s hard to hit deadlines every time. The results I’ve seen are so good that I can’t complain over small details like a 1–2-day delay.
What did you find most impressive about them?
Working with InventorSoft has been completely different; it’s not all about money. We have a good relationship and they want to make the project successful. I can really feel that InventorSoft is putting in time and effort and that they always do everything they can in order to make things happen. This is what really makes me feel comfortable since the cost is significant for me and I have to feel safe in investing it.
Are there any areas they could improve?
Not right now. I will have to wait and see how the platform unfolds. InventorSoft has been working hard and I cannot complain about anything.

InventorSoft was hired to work on a variety of projects for the client, including creating APIs [application program interfaces], as well as doing PSC to HTM coding.
The client was extremely satisfied with the work that InventorSoft did, noting what a good value they have.
A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.

We are a vitamin and supplement business. We do private labeling. We have our own backend and we work in Finland, Sweden, and Norway, and we’re emerging in Germany. We are located in Estonia where we have our distribution center and our management.
I am the Chief Operating Officer.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with InventorSoft?
We have used them in building APIs and PSC to HTML coding - creating business to business services.
SOLUTION
What was the scope of their involvement?
They’ve done APIs from scratch. They have created multiple PSC to HTML.
How did you come to work with InventorSoft?
We found them at Freelancer.com or a service like that. We agreed to work directly.
How much have you invested with InventorSoft?
The project cost $50,000.
What is the status of this engagement?
We have been working for a year or year and a half. Some projects are finished and some are ongoing, with more to come. We want to work with them in the future.
RESULTS & FEEDBACK
Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?
We’ve been very happy with their work. We have had a fixed price, and if we have issues with the API, they have always fixed everything without any charge.
How did InventorSoft perform from a project management standpoint?
I’m very happy with them. They have even fixed issues that were not related to their end coding. I’ve asked them to charge us for the additional work, but they haven’t done that every time.
What did you find most impressive about InventorSoft?
I’m not good at coding myself, so I can’t say how well the work is done. I can just say I’m very happy with it and the results have been good.
