Oh they raised a pretty large seed. But they don’t seem to have a business model, or at least I cannot find details on how they plan to make an actual business

I'm not sure what's been published but as someone who plays with tangled as a hobby the immediate monetisation paths I could see are:

- Charging to bypass the (admittedly very reasonable) rate limits on the main appview

- Providing paid hosting tiers for private git knots, high traffic git knots, git LOP knots, CI runners/spindles, web page hosting (via their github pages equivalent), etc

- Introducing a paid-for and permissioned nix binary cache platform since their CI spindle system is already nix-first.

- providing paid PDS hosting for corporate/business customers with SSO integration etc.

- SLAs and support contracts

There's enough options here that they have a pretty flexible path towards profitability.
