OpenHack

Always on AI Security Engineer. Backed by @ycombinator and @solofounders

[OpenHack @openhack]

We’re thrilled to announce that OpenHack is now a part of @ycombinator Fall 2026! 🙌

Excited for some amazing product announcements very soon.

Excited to share that @OpenHack is now part of YC Fall 2026! 🚀

Feels pretty surreal to be writing this, after building, shipping, selling and figuring things out the hard way.

Despite all advancements in security tooling, organizations still struggle with false positives, knowing what to fix first, and AI-assisted attacks moving faster than ever.

That’s why we’re building an always-on AI security engineer. One that is the most context aware - knowing your business, developer intent and system architecture deeply. It can hunt, reason, prioritize and verify vulnerabilities based on true business impact like a real security engineer.

It’s a much harder problem to solve than it looks on the surface, and we’re just getting started.

Back to building. 🫡

This is exactly why we built OpenHack. Model restrictions slow down our ability to find and defend against vulnerabilities; gating them behind cyber use-case forms.

First month of OpenHack Pro is free btw, code "DEFCON34".

[Ananay @ananayarora]

> got approved for Anthropic Cyber Program in April
> somehow got removed (?)
> claude refusals across the board
> applied again today
> approved in 20 mins
> claude refusals still across the board

everyday i become even more bullish on open source models

‼️ ATTENTION ALL DEFCON ATTENDEES ‼️

Free OpenHack Pro for a month with code "DEFCON34"

Thank you for your attention to this matter.

[Ananay @ananayarora]

Due to high signup volume and large scale abuse overnight, we're temporarily suspending our free credit bonus.

Instead, we're offering a month of free Pro plan while DEFCON is going on. Use code "DEFCON34" to get one month of free OpenHack Pro!

Happy Hacking!

[Ananay @ananayarora]

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.

AI will transform every industry, power every company, and be built by every country.

Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.

The world needs both frontier closed models and frontier open models.
