What clients say about us

Overall experience of working with Limestone was really great: the thing that I like the most is that they are always thinking one step ahead. And I can tell that results are delivered very fast!

They have just been phenomenal in not only accomplishing what we’ve set them up to accomplish but suggesting better courses for us to take that we might not even thought of on our own and that has been invaluable for us.

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 [...]
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 familiarize 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 an 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.

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.

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

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.

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.
