I'm Michail. I co-founded Rehive in 2015 and have been building it ever since. It's a platform companies use to launch and run their own stablecoin and fintech apps. We started in Stellenbosch, and I've since lived in San Francisco and Amsterdam. I'm now in Barcelona, where my wife and daughter are from.
