Software Development Review from Robert de Burgh-Day

KeenEthics has been our software development partner at Brightspace for our analytics dashboard platform, and the experience has been consistently excellent. As a hardware and AI company, we needed a team that could take complex real-time occupant and environmental data from our edge devices and turn it into dashboards that facility managers and building owners actually want to use. KeenEthics delivered exactly that. What stands out most is how they work. Communication is clear and proactive, sprints run on time, and when requirements shift, as they inevitably do in a fast-moving startup, the team adapts without drama. They ask the right questions early, push back constructively when something could be done better, and take genuine ownership of the product rather than just ticking off tickets. The quality of the work speaks for itself. The dashboards they have built are now a core part of our commercial offering across multiple markets, and they have held up well as we have scaled deployments. Costs have been fair and predictable, which matters enormously for an early-stage company. I would not hesitate to recommend KeenEthics to any company looking for a reliable, high-quality development partner, and we intend to keep working with them as Brightspace grows.

Web Development Review from Khrystyna Sliana

We collaborated with this company while supporting our client with a request focused on a TypeScript, Node.js, and Angular stack.After engaging them through our partner network, they quickly shared a strong candidate who turned out to be an excellent match for the clients needs. The developer demonstrated solid technical expertise and professionalism throughout the entire engagement, which was highly appreciated by both our team and the end client.At the beginning of the collaboration, there was a need to adjust the developers working schedule. Keenethics handled this situation very efficiently, resolving it within a few days and ensuring full 8-hour availability. Their responsiveness and problem-solving approach made a strong positive impression.We are very satisfied with both the quality of the specialist provided and the company's ability to react quickly and effectively to operational challenges.

Software Development Review from Michael Meyer

We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!
