I run an open-source [1] email verification API, called Reacher. I managed to hit 10k ARR this year (1st year).

It's written in Rust, self-hostable, and does not use a DB of emails (like some competitors do).

Landing page: https://reacher.email.

I love the design of the landing page. Did you design and build it yourself?

> does it come with its own DB & all?

Also, there's no DB. Each verification is done in real-time.

Author here. Yes the company is in France, and I'm currently writing those (called "CGV" and "Mention légales").

Fixed, thanks!
