Fintech companies have paved the way as being a new innovative way to address people's need with a lot of flexibility, shared on large scale
There are several groups for Fintech Startups on Facebook and Linkedin. I would suggest searching there.
Additionally you can try this unique approach. Go to Google and enter "Fintech Site:io" and "Fintech Site:.ai"
This limits the search to startups whose domains end in .io and .ai.
Fintech companies use these domains because .io to them represents input-output and .ai represents artificial intelligence.

I live in Kenya and have been working in the start up community for the past several years. The two top resources would be:
A) A newsletter called "TheFinTech" which provides a general overview.
B) Nest Nairobi, an accelerator also publishes reports.
Let me know if you'd like to set up a call, it would be helpful to know more about your search. Thanks
