One builder, a fleet of agents

I run Hasna, an AGI lab of one builder and a fleet of AI coding agents. I bootstrapped a healthcare business to eight figures, pivoted everything to AI, and now I ship open-source building blocks for AGI — close to 100 repositories and counting.

From a healthcare business to AI

My first company was a healthcare business, started from a blank page with no investors and no safety net.

I bootstrapped it to eight figures, and it paid for every lesson I still use: ship fast, keep doors open, make risk cheap to execute.

Bootstrapping Success

Bootstrapping that first company — no investors, every mistake paid for in cash — is the foundation everything since is built on.

The honest version of that story — what worked, what broke, what it cost — is my first book, “I am Entrepreneur.” It is out very soon.

HASNA: AN OPEN-SOURCE AGI LAB

In 2022 I co-founded Hasna with my wife, Diana. Today it runs as an AGI lab of one builder: fleets of coding agents working around the clock, close to 100 open-source repositories under @hasna/*, and over 170 billion tokens spent building with them.

Beyond the code

Speaker & mentor

I have spoken twice at Techsylvania — in 2024 on staying competitive when AI can disrupt any business, in 2025 on how AI agents can save your job — and gave a TEDx talk in Cluj in 2024. I share what I learn as I learn it.

I also do advisory and consulting work with teams building with agents. Write to hello@andreihasna.com or book a session.

“As humans, we are creatures of ego.

One lesson I learned early on is that relationships should be maintained and doors should remain open, even when it may seem counterproductive.

This applies to both former employees and business partners. Abundance should be collective.”

The plan from here is more of the same, on purpose: more agents, more open repositories, more of the boring work automated away. Not a bigger company — a small lab that ships like a big one, building AGI blocks and having fun doing it.
