Loved by Builders.
Working with Flair has been great! From our first meeting, Aram and Kasra have been nothing but helpful, supportive and problem-solving. With Flair, Castle of Blackwater was able to deliver a state-of-the-art NFT staking protocol for our community. We look forward to our future collaboration.
Working with Flair has been such a great experience. We've had hands-on support from day 1 and Kasra and Aram have acted as advisors to us on more than one occasion. They are genuinely invested in our success. One of the best technology partners we have had the pleasure of working with!
By using Flair platform, we were able to get a turnkey MVP in one digital meeting. The tech and tools available on their platform is truly unparalleled for game developers and Web 2 accessibility. The flair team is god-tier. We just saved months of development and headache, thank you!
