We're democratizing AppSec.
Three engineers building world-class AppSec for the AI coding agent era. No enterprise-only gates. No Jira black holes. No vuln, no bill.
Cofounders, all engineers
LOC/day shipped per active dev
EU + US regions
Make digital safety a standard, not a luxury.
We're a passionate team of cybersecurity and engineering builders driven by a single conviction: every team that ships code deserves application security that works with the way they actually code today.
Security review meetings don't scale to agent-time. Scanners built for human-paced PRs miss the logic flaws that ship at 5,000 LOC/day. We're rebuilding the whole stack, in the agent loop, at agent speed, with verdicts that arrive before the line is even written.
Founded in early 2025, opening a Seattle branch in 2026. Built for AI-native teams everywhere.
Three founders. One mission.
Engineers who shipped AppSec inside scale-ups, watched their tools get bypassed by Copilot in 2023, and decided to build what should have existed.

Four values. Zero compromises.
The principles we test every decision against, from a pricing tweak to a CWE rule shipped at 3am.
Innovation
Leveraging AI and agent-loop architecture, we stay ahead of the curve, continuously rewriting what AppSec means in the agent era.
Accessibility
Advanced security should be available to every builder, regardless of company size or budget. Free tier, transparent pricing, no enterprise-only gates.
Transparency
Clear pricing. Open documentation. Honest verdicts. We refuse to add to the alert pile, if we can't verify, we don't page.
Collaboration
Built for teams. Bridging developers and security engineers with one source of truth that lives where the code is written.
We're hiring builders.
Whether you write code, sell software, design products, or care for customers, there's a seat at the table for builders who want to redefine what AppSec means in the agent era.
