This is an amazing project - thank you for building/sharing it!

Shameless plug: We're building this. Our goal is to provide AI pentesting agents that run continuously, because the reality is that companies (eg: those doing SOC 2) typically get a point-in-time pentest once a year while furiously shipping code via Cursor/Claude Code and changing infrastructure daily.

I like how Terence Tao framed this [0]: blue teams (builders aka 'vibe-coders') and red teams (attackers) are dual to each other. AI is often better suited for the red team role, critiquing, probing, and surfacing weaknesses, rather than just generating code (In this case, I feel hallucinations are more of a feature than a bug).

We have an early version and are looking for companies to try it out. If you'd like to chat, I'm at varun@keygraph.io.

I think they refer to: IB - investment banking PE - private equity HF - hedge funds or High Frequency trading (?)

Tangent: Did Windsurf actually get acquired by OpenAI? I would have imagined some sort of announcement from OpenAI at the very least? Bloomberg was the one to break that news too, but haven't seen any follow up.

Does anyone have insight into Neon's financials - specifically their revenue, COGS, and gross margins? I'm trying to understand what made Databricks value them at $1B. Was it strong unit economics, rapid growth, or mostly strategic/tech value?

Dagger (https://dagger.io) recently seems to have reinvented/rebranded itself as some llm agent platform.

Agree - that’s what we use too.

Wow that had been quite a journey - thanks for the detailed response. We’ve been using cel internally in a golang codebase and been pretty happy with it. I’ve only know about starlark in the Bazel context - I’ve learned a couple of things from your post. Thanks :)

This looks cool - will give it a try (hah!) Curious on why you picked starlark instead of cel for the conditional scripting part?

Congrats to the team. IIRC their CTO was the creator of RocksDB.

Thanks for the detailed answer - please turn it into a blog post! Excited to see competition and different architectural approaches to tackle durable execution. Wishing you all the very best!

Feedback: everybody’s question is going to be on why this over temporal? I’ve noticed you answered a little bit of that below. My advice would be to write a detailed blog post maybe on how both the systems compare from installation to use cases and administration, etc - I’ve been following your blog and while I think y’all are doing interesting stuff I still haven’t wrapped my head around how exactly is restate different from temporal which is a lot more funded, has almost every unicorn using them and are fully permissively licensed.

I agree - and flagged it as a result. It is clearly a hit piece and has promptly even made it to Prabhakar's wikipedia page: https://en.wikipedia.org/wiki/Prabhakar_Raghavan
