About
The first partner for technical founders. We turn groundbreaking research into transformative investments, fueling the next generation of AI-native startups.
Investment approach
- Thesis
- We are a research-driven venture fund backing AI-native companies at the pre-seed and seed stage. We publish long-form technical research on the building blocks of AI, work that has been cited by Nature, The New York Times, Bloomberg, and CNBC. That research is not marketing. It is how we invest. We partner with technical founders before the category is obvious. Our conviction comes from the research, not from consensus, which means we are often the first institutional check a company raises, backing teams while the market is still catching up to what they are building. When we invest, we stay close. We engage at the level of architecture and roadmap, not just board meetings, and we put the full weight of our research and network behind every company we back.Source (opens in a new tab)
- Traction requirement
- The Alpha Program isn’t about chasing early metrics. It’s about validating what needs to be done for your idea to take off.
