This is such a valuable idea and Luis and Aamir are absolutely crushing the execution. Their revenue growth rate is one of the highest I've ever seen!

One of the coolest ideas in the batch!

Introducing TareBio: going founder mode on anyone's cancer

Understudy Labs helps companies cut their Anthropic bill by 80% - with no loss of performance 👀

This company is performing novel material science research using failed experimental data (that would otherwise never see the light of day)!

super excited! this is good use of AI to tackle the most complex cancer cases along patient’s complete medical record and personal genomics

yes those metrics are real such a pleasure working with Grace Li and Kamryn Ohly. It's crazy it's only been a year since they messaged me "Hey I think this arena thing is taking off on reddit". Congrats on all the incredible work!

20,000 tokens/second is coming 👀

The next biggest challenge in drone warfare isn't targeting the drones - it's finding the operators. This brilliant team has the solution America and Ukraine badly need

Is it just me or are startup launch videos getting insanely good? Personalized probiotics that actually work. Love it.

Every company is going to have autoresearch as a core method of product improvement. hiloop makes that easy These guys are experienced engineers from Reducto building a product every growing company should want. Congrats on the launch!

Congrats Sammy Greenwall and Adam Pratt and the entire team! $16.5M Series A led by FirstMark. The idea of automating the commercial real estate process seemed crazy a couple years ago. Now it feels inevitable.

Congratulations Sammy and Adam on your round and the launch of Henry Deal!

So excited about Hop Aero. They're building rockets that can deliver cargo anywhere on earth in 15 minutes(!)

Today Traceforce launches in the S26 batch. It arrives at a moment when every office in the country has quietly filled with machines that think. ChatGPT, Claude, Cursor, Claude Code, all of them humming away on ordinary laptops, doing extraordinary and sometimes reckless things. Traceforce lets a security team see them at last, and stop the dangerous ones before the damage is done. You can try it free, in less than five minutes, at https://traceforce.ai. I was really impressed by this team because Xia and Varun have already lived through these problems. At Clumio, where Xia was director of engineering, an AI agent on a developer's laptop reached out and took what looked like database credentials, and pushed them into a public repository for anyone to find. It cost them weeks of investigation, of rotating keys and clearing away the wreckage. They're building Traceforce to save other companies from this pain. If you keep watch over a company's security, or you know the soul who does, write to Xia at xia@traceforce.ai. Try it on your own laptop.

take a minute out of your day to watch the most mind-blowing video I've seen this year

This is the single most impressive demo I have seen in the last year, and I would say is probably the one that has most meaningfully moved forward my AGI timelines. Vincent and Hanming are two brilliant researchers, and they figured out that you can use the "trick" from Claude Code and bring it to robots: give a frontier model a set of tool primitives to control robots. If you do this, it turns out the robots can self-teach impressive skills. And then those skills can be shared and built upon. Their video shows how in a few minutes, they can replicate the demos from Figure and Physical Intelligence, which spent hundreds of milllions of dollars on custom hardware/software to achieve the output. try it out now. this one is going to be special

Heart Aerospace X1 is cleared for flight.
