Prototype

We back exceptional founders early, investing in breakthrough technologies that amplify individual agency with conviction before consensus.

On the side of the individual. AI is concentrating judgment in a handful of companies. We back founders who extend it to people instead: tools where the user owns the model, the data and the decision.

Portfolio

Alljoined: Non-invasive brain-computer interfaces. Alljoined trains deep learning models on large EEG datasets to decode brain signals into images, text, and intent.
Foundable: Meet Ted, your AI employee. Tell him your idea, and he builds the business and does the work for you.
Hacktron: An AI-powered security platform that finds, proves, and fixes exploitable vulnerabilities on every code change.
Paxos Labs: Infrastructure for onchain finance. Paxos Labs lets fintechs, banks and platforms issue branded stablecoins and offer yield and other onchain products to their users.
Sail: Infrastructure for long-running AI agents: low-cost inference for open models, plus sandboxes that keep agents working for days or weeks.
Sonilo: AI that scores video. Sonilo reads a clip’s timing, pacing and emotional arc and generates a soundtrack to match, no prompts needed.
