Excited to introduce @Cosign: the curated professional network for the startup community: cosign.co Our goal is to create the following: - A comprehensive startup directory of investors, companies, and operators, including what they worked on and who they worked on it with. - Cosign graph: Who shaped your career? Who were you actually in the trenches with? Who would work with you again? Who thinks you’re someone to watch? - Durable reputation: Great endorsements happen every day on X and disappear into the feed. Cosign attaches those signals permanently to people and companies. - Discovery: Who are the best fintech angels? Which AI companies should I watch? Who are the best designers? - Intent network: Privately signal “I’d invest in them,” “I’d hire them,” “I’d work with them,” or eventually even “I’d acquire this company.” Match people when interest exists on both sides. Imagine if Wikipedia, LinkedIn, and OG AngelList had a baby. Though Cosign is a community, not a business. In order to join, you need to be cosigned. Or you can apply directly. David Booth and I started this idea 7 years ago but didn’t have the firepower to make it work. Now we do. No one has really touched LinkedIn in 20 years. Excited to take a swing. cosign.co

1/ Ethos just completed our largest payout cycle ever. We now average $1M/day paid to experts worldwide: tens of millions a month to tens of thousands of people. 2/ Behind every payout is a real person. One expert, 20+ years in enterprise sales and a year without work: "Ethos came at a time when I was really down and not sure if I would work again professionally." 3/ Another put it better than we can: "It made me realise that my experience isn't becoming irrelevant because the world is changing." We're building for a future where human opportunity grows in tandem with AI. 4/ To our team, who worked every weekend to scale operations for tens of thousands of active experts in days: thank you. You did in months what takes most companies years. This is only the beginning.

OpenAI researcher @Houda_nait on the diseases capitalism can’t afford to cure, and how AI could finally change that: "There's maybe 10,000 rare diseases in the US which touch 30 million people, and there is a cure for less than 5% of them. That's crazy to me." "If you are a child who's born with a rare disease, your probability of getting treatment is lower just because there's too few people who have the same mutation." "The reason why we don't invest as much in those diseases is just pure capitalism. It's irrational for labs to pursue treatments for those diseases because the expected payoff is lower. But today you can start finding more labs investing in those because it's cheaper to try." @OpenAI
