About

The bottleneck is the interface.

I'm a hacker turned founder. I dropped out of math & game theory at TU Munich, went viral on X for local-first AI demos, and got into Y Combinator twice. Today I'm building an LLM OS: the operating layer where the model, your data, and the interface meet, with a focus on generative UIs, screens that compose themselves in real time around the task at hand.

Generative UI
Interfaces that compose themselves at runtime.
AI agents that act
Crawling, matching, and outreach at Stormy scale.
Local & on-device AI
llama.cpp, client-side vectors, WebGPU. Fast and private.
e/acc · physical AI · lifting
Optimistic about intelligence getting cheap and abundant.

Work

Companies & open source

Stormy AI YC S24
Founder & CEO. AI agent that finds, vets, and negotiates with creators end-to-end. 5 people, SF.
Fixkey Acquired
Native macOS AI writing copilot. Type at the speed of thought, real-time STT on Groq.
ngrow.ai YC W22
No-SDK AI push notifications for user engagement. My first YC company.
BakLLaVA Realtime Viral
Webcam narrated live by a vision-LLM, 100% local via llama.cpp. Sparked countless imitations.
Client Vector Search 230★
In-browser embeddings that beat ada-002 and outrun Pinecone. No server calls.

Story

The path so far
