Spent three years looking for a team in Biodefense to invest in. But never found one. So we built it ourselves. Valthos builds next-generation biodefense. As AI and biotech rapidly advance, we're approaching near-universal access to tools with the potential to cure humanity or

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

AI is set to help unlock biology at unprecedented speed, and we need this acceleration to yield more cures than threats Proud to back @kath_mcmahon and @ValthosTech to redefine biodefense for the AI era !

LFG - biology is the threat model I'm most worried that our world is vulnerable to in the near term - super excited for Tess and co to tilt the offence/defence scales back

Really great and important initiative - i criticize OAI when I believe they are straying from their mission but this is an example of an area where they are head and shoulders above many of their peers and we need far more programs like this

One of our greatest risks is AI-enabled biological threats. As models advances, it’s becoming easier to design a weapon than a cure. Proud to back @ValthosTech@kath_mcmahon, @velvetatom, and team advancing America’s speed and ability to design precision therapeutics 🧬⚛️ 🚀

The ability to anticipate and act on the trajectory of natural and even man-made biological threats is a critical defense capability, and AI advancements only make it even more so. (1/2)

Years of working on AI + programmable biology left me convinced: capabilities are racing ahead, and so are risks. Valthos started because we need better defenses. I joined at formation last year as the first hire, and grateful to be tackling this alongside a world-class team.

Technology enabling push-button biology will cure disease and aging. But it also enables dual-use risks that cannot be ignored. @velvetatom is relentless, intelligent, and bold. Glad she is building our biological defense axis to make sure that we flourish from this technology.
