I've started a new role as co-founder & COO of Freebuff.
Our mission is to build great consumer AI products and make them free, by running ads.
We are starting with an ad-funded coding agent.
I met @jahooma on my first day in SF in 2024.
We became roommates and did many office hours with each other on our respective startups.
It's an absolute pleasure to now build a company together.
Excited for the new chapter!

Bullish on this team! We love helping Juno with customer support.
