The team looks good. Can we have some details like their previous experience in the blockchain. That will surely keep a lot of people interested. Also, is this the first time that someone is going to use stellar blockchain? If yes, i think you are going to have the first mover advantage. But also, in that case there will be no past learnings available?
I've answered your second question in the previous posts. As for the team and our experience:
Our CTO - Dmytro Khovavko has extensive experience in blockchains and security systems. Previously, he developed trading bots for private equity firms, participated in the development of the prototype for distributed database based on the blockchain, but most importantly he has an extensive experience building security systems based on asymmetric cryptography for real-world banks. Dmytro also worked at Wargaming.net (Word of Tanks), Brokbusinessbank, Luxsoft, and Siemens.
Our COO - Serge Ustiuzhanin is also a full stack developer with 18+ experience of building projects for IBM Security, Mercedes-Benz Research & Development North America, HSN, JWPlayer and Inc Magazine to name a few. Serge has extensive experience in building web and mobile apps, so in a team with Dmytro and our awesome designer Tony we have everything we need to bring Gratz.io project to success.
