Why is this free?
I'm Deniz — a solo developer from Munich. I built GeniusLead as a one-person project: the SMTP relay server, the verification pipeline, the entire platform. No VC money, no sales team, no offices in San Francisco.
Because I run everything myself, my costs are 80x lower than ZeroBounce or NeverBounce. Instead of pocketing that margin, I pass some of it on — so you can see what European tech products can do. No dependency on US tools. Your data stays in the EU.
The verification runs on my own SMTP server in Germany. No API reselling, no outsourcing. And when you need 500 or 5,000 emails verified for your cold outreach campaign — you already know it works.
