In my opinion, one of the biggest fintechs in AI is currently EndoTech. Normally only for institutional investors available.
on 30 March they relaunched the project called D.AI.SY. A combination of crowdfunding for the next Level of AI (als quantum technology) where everyone can participate and use the AI robots from EndoTech for his investment. All based on multiple smart contract.

Here you can combine both:

• a big selection of deposits, starting already at 10 Dollar and daily profits of 1.3 percent a day
• four currencies for selection (USD, BTC, ETH, LTC)

The daily profit is payed out daily! Deposit, withdrawal and switching between the currencies works quickly.
