It's a mesh built on low cost custom hardware. Each node is also super powerful with >128gb storage and some nice computation power, with a GPU to boot :) We're looking to be more than just an ISP in the long run.

For what value of "more than just an ISP"?

A sort of AWS style platform for retail. Eg. Are you building a POS or Inventory app or do you want to sell your online goods offline? You can access our merchants and authenticated users that already have a prepaid wallet and are at a retail location predisposed to buying. And because of our connectivity, you don't have to worry if your users have internet.

Or maybe an IOT platform of sorts, for example, you're an FMCG and you want to know that your shipments really did arrive at the location your distributor was supposed to deliver it.

India's a challenging country where > 80% of our retail is fragmented into millions of micro-stores.

So using the user's phone just for auth, akin to cards? Nice idea!

What do you need the GPU for? The box does not appear to have a display.

A distributed machine-learning network for some whatever reason :)

If you buy a cheap ARM SoC, there's a decent chance that you get a GPU "for free" (in the sense that chips without a GPU turn out to be more expensive).
