Before RSVR, we worked with top agencies that overcharged, overpromised, and under- delivered. Switching to RSVR was a breath of fresh air—their team was flexible, quick to understand our challenges, and integrated seamlessly with our own. They picked up our MVP with minimal handover, making the transition smooth and productive from the start.We were very satisfied with the services provided, not only were all of our requirements met but the partnership also led to a strong, lasting relationship—something few start-ups can say about their technology partner. We vouch for RSVR and have been happy to spread them to our close network.

We began working with RSVR shortly after our first fundraise when we were ready to bring on a new technical partner. Having previously worked with teams in both the UK and India, it was great to collaborate with a team that has a base in the UK for smooth communication and project management, while leveraging the brilliant technical skills of their team in India. RSVR helped us completely revamp our existing platform, integrating a range of new features and technology. It’s been a pleasure to work with them, and as I often tell other founders, their great communication and ability to consistently deliver on time have made all the difference!
