Have loved @clerk since the first time I used it, and been waiting for this since the @stripe investment. If you’re a builder, you know how annoying SaaS billing set up can be, and tracking membership levels, etc. Absolute game changer here. Let’s goooo 🚀🚀

We're in the home stretch for Clerk Billing

Private onboardings are happening this week 🚀

GA is very close. Mostly dashboard tweaks at this point

So excited to get this in your hands 😄

Industry expert ➡️ solo founder ➡️ acquisition (@zeroshotsec ➡️ @TidalCyber)

My founder journey has been both unique and completely stereotypical. Truth is, some lessons you can only learn in the trenches.

New paper: @BrianSinger98 and @AnthropicAI Frontier Red Team member @keenlooks investigated whether models can use tools to execute multistage attacks on networks.

TLDR: yes

Models will increasingly be used for security research.
