Put them on your radar! 800,000 physicians use this platform including 1 in 4 in Spain & Italy! They now have more daily active users then monthly active users within months! Built with a team of 12 they are the most downloaded app for clinicians.
Every month since June, Vera has been the most downloaded clinical app in the world. We now have more daily active users than we had monthly active users just a few months ago, when we raised this Series A.

From 2011 - 2014, the Thiel Fellowship gave out 40 $100k fellowships to entrepreneurs That were all under 20 years old at the time... 13 unicorns have since been built by those 40 fellows 4 of those 40 fellows are also now billionaires Absolutely insane hit rate

A very important company for the AI era
Today, we’re announcing Infisical’s $40M Series B at a $600M valuation, led by @eladgil. AI has made it 10x easier to write code, 10x easier to find vulnerabilities, and given autonomous agents access to some very sensitive systems. The problem is that much of today’s security infrastructure wasn’t built for any of this. We’re changing this with @infisical. Today, over 1,300 organizations trust us to secure their infrastructure, including Airbus, First American Financial, Hugging Face, OpenRouter, and Wise. Proud of what our team has built so far. Even more excited about what we have ahead of us. Back to work.

Congrats @infisical on their $40M Series B led by @eladgil 🚀 Psyched to be the lead seed investor @GradientVC the leading platform for agent security!
We’re excited to announce we have raised a $40M Series B! This next round of funding lets us continue to strengthen our secrets, certificate, and access management products. We'll also expand the capabilities of Agent Vault, so engineers adopting AI agents can give them access without handing over the underlying credentials. Thank you to @eladgil, @GradientVC, @ycombinator, and our other investors, as well as our customers, community, and team for helping us get here!

Anthropic cofounder, Chris Olah, was a 2012 Thiel Fellow alongside Dylan Field, the 2nd class... Chris started with 3D printing + open-source design software. But the Fellowship's whole thing is a bet on people, not just their first idea. The program has an insane hit rate...

Imagine knowing these circumstances and deciding to green light this ad anyway. We are so numb to the gutter politics of this era that it’s sometimes hard to shock but I have a feeling Mike DeWine and John Kasich Republicans are going to be disgusted with Ramaswamy on this one and it costs him more votes than Acton.

Introducing RecruiterBench, the people-search benchmark most aligned with recruiting workflows. At Wrangle, when developing our internal models, we realized that all existing people-search benchmarks (that we’ve seen) are flawed: - They only score 10 candidates Real recruiting workflows require sourcing through 100 or more profiles to make a hire. Evaluating accuracy across 10 people doesn’t provide an adequate picture of how a tool will perform on a req. RecruiterBench measures precision over 200 returned candidates for each role, which we believe accurately represents search capabilities and performance. - The queries are overly simplistic and contrived Accuracy over “Product managers in Austin” doesn’t matter when you’re looking for someone with a specific skillset. We built RecruiterBench on 290 complete active reqs on Ashby, spanning 58 unique industries. This also allows us to find unique insights, such as what industries and role types each tool excels or struggles with. For example, some strong points we identified are: Wrangle deep on AI infrastructure: p@50 of 60.4%, versus Metaview 39.6%, Wrangle Turbo 52.2%, Exa 21.8%, and Treg 9.6%. Wrangle deep on food/agriculture: p@50 of 79.4%, versus Wrangle Turbo and Metaview at 56%, Exa 24.6%, and Treg 9.2%. Juicebox on legal: on the same three roles, p@50 was 82.7%, ahead of Turbo 76.3%, Metaview 65.7%, Exa 55.7%, and Treg 11.7%. Wrangle Deep still led at 93.3%. Metaview on Advertising/marketing tech: p@50 was 78.2%, leading Wrangle Deep's 77.8%, Wrangle Turbo’s 73.8%, Exa’s 45.6%, and Treg’s 17.6%.. - They evaluate with a single LLM judge, without nuance about must-have, dealbreaker, and nice-to-have criteria RecruiterBench uses a two-part LLM scoring system to first disqualify candidates based on must-haves, dealbreakers, location mismatches, and over/underqualification. Then we use a second judge to determine relevance and give no/partial/full credit. We’re excited to continue developing more accurate benchmarks, and to build the best recruiting tool in the world!

this is cool - need more evals for real work
AI progress becomes economic progress when models can reliably do the work people need done. Today, we’re launching evals built with practitioners on real-world work from the 75+ businesses that are part of @ThriveHoldings. evals.thriveholdings.com

Enterprise next
Meta having: - frontier lab + talent - SOTA model - $50b/yr in FCF to fund compute buildout - IG credit rating (70bps spread) if they want to fund more than $50b/yr - distribution to 4bn ppl - organic data in from 4bn ppl = lower mkt cap than Anthropic IPO price Ok.

and they use wrangle.ai to hire ;)
Fastest company ever to $1b annualized revenue Nope it’s not Higgsfield or Cursor or Cognition. Met a data company yesterday that did 0 revenue in November 2025 and 80m “in month revenue” in September 2026. They will hit $1b annualized from 11 months of being started. They are still under the radar so I can’t share who they are. Hopefully soon, with their permission. I don’t make the rules.
