Automated Nano-Capital?

I've been rolling around a thought experiment for automated nano-capital but I'm not sure whether 1) it's been tried or 2) it's possible.

Basically, I'm thinking of super small, early-stage projects - one or two people building a tool or service with a few dozen (no more than 100) paying users. Instead of taking a loan or going to traditional venture capital, they provide programmatic access to their payment provider (e.g. Stripe) to the nano-capital platform which pulls the their data, runs an evaluation, and returns offer terms in a couple seconds.

Personally, I like the idea of this term offering being along the lines of the Shared Earnings Agreement (https://docs.google.com/document/d/10KNj6HJpfF9EjssJzRaGIw2LBxEdawjWbtfLZCGLFl8/edit) offered by Earnest Capital (https://earnestcapital.com/).

As far as existing approaches, CaaS (https://caas.socialcapital.com/) at Social Capital (https://www.socialcapital.com/) seems to be close with a quasi-automated, quantitative focus. Also, Pipe (https://www.pipe.com/) could be seen as similar since it's trading existing monthly subscriptions for annual lump sum value.

But what I'm thinking is even smaller - super small amounts like $500-$5000 that are just enough to help builders scale their MVP.

- is it feasible to calculate a nano investment on such a small user dataset?

- is this amount impactful enough for builders to be interested in applying?

- is a shared earnings agreement the best vehicle for extending the terms?
