    1/ I spent a long time at Palantir chasing hard problems with brilliant people (can recommend). So I think I know a good quest when I see it. Excited to announce that I started Valthos with @velvetatom and an incredible team

    Valthos builds next-generation biodefense. Of all AI applications, biotechnology has the highest upside and most catastrophic downside. Heroes at the frontlines of biodefense are working every day to protect the world against the worst case. But the pace of biotech is against

    Could not be more excited to work with @jasonkwon and the @OpenAI team on this mission—they've been leaders in identifying the risks and driving forward the tech we need for the next era of biodefense

    One of the greatest opportunities in AI safety and security is the chance to help support the creation of new industry verticals that help maximize the benefits and minimize the risks. The technology is moving fast. One of the best ways to keep up is with more technology, more

    3/ We have an opportunity to use emerging AI methods to strengthen biodefense - earlier detection of threats, faster, more precise medicine. It’s a race to get these systems in place to deter the worst case and we’re running out of time. This is the problem I want to solve.

    4/ I met some insanely talented people who feel the same way, and we started Valthos to bring our experience in operational software & ML to the experts on the frontlines of biodefense.
