I’m Aj. 2x VC-backed founder. $30M raised. Products used by 20M+ people.

Last year AI made me feel behind. I hadn’t written real code in 15 years. So I started building live every Sunday — no slides, no script, just shipping in real time with whoever showed up.

That turned into vibe coding, then AI agents, then automation. Now I’m angel-strapping my third startup, Otto AI, while vibe shipping ClawShip and UseVoice.xyz solo.

If you feel behind on AI, you’re exactly who this is for.
