It's like API indexing, I like it. I started M3O (https://m3o.com) with this idea of API aggregation for absolutely everything but not specifically indexing, more so providing a uniform access layer to all things with one API token. The programmability of Nango will definitely a be a selling point. For the founders, focus on that, double down on that. The ability to program the APIs and the data retrieved is really key.
Kinda random question, but is there a name for the theme/style used in your website? I like it and I know it's pretty common (dark, minimal, pink, gradient, etc.) but not sure if it has a name. It looks like you used tailwind css. Just looking for more specifications on this type of style.
