I am a strong supporter of Dataeum:
https://dataeum.io/Firstly, they really need the blockchain for their solution.
Secondly, the team has strong management and business skills.
Thirdly, they've already tested their biz model, and it proved scalable.
Finally, they have an MVP. And Simon Cocking as an advisor. I really think they'll rock.
