The Technical Co-founder We're Seeking

We need someone who understands that great technology serves human needs, not the other way around.

You're not just a technical leader - you're someone who believes that the best software feels invisible, that elegant architecture enables beautiful experiences, and that the most powerful feature is often the one you don't have to think about.

You've built systems that scale, but more importantly, you've built systems that matter. You understand that when we're processing 100,000 newsletters daily, we're not just moving data - we're preserving thousands of hours of human creativity and enabling millions of moments of discovery and reflection.

A Final Thought

Reading deserves a sanctuary. We're not here to fight for attention. We're here to protect it.

We're building Inbo.club for everyone who has ever saved a newsletter to read later, only to lose it in the noise. For everyone who believes that the best technology is the kind you don't have to think about. For everyone who thinks the internet could be a little more thoughtful, a little more human.

If you're someone who wants to build technology that serves human flourishing rather than exploiting human attention, we should talk.
