Developer sourcing for the vibe-coding era
Find developers
who think in systems,
not what they type.
The real problem isn't interviewing — it's finding signal in a pile of polished, AI-assisted submissions. Langos cuts through the noise by revealing how a developer reasons, not just what they ship.

The Problem
Finding great
developers just
got harder.
Every candidate now submits polished, AI-assisted work. The signal is gone — and the tools built to find it haven't caught up.
Three filters that no longer filter
Résumés are indistinguishable
ChatGPT writes a compelling senior engineer profile in seconds. Every applicant now looks like the candidate you're looking for.
Take-homes are trivially AI-completable
Any task you can set, a model can solve. You're no longer screening for skill — you're screening for who remembered to run the linter.
Thinking style is still completely invisible
The most predictive signal — how a developer reasons, overrides, and refines — is never captured by any résumé, test, or portfolio submission.
The Solution
Meet Langos — a sourcing layer
that reveals how developers think.

They work naturally with AI
No restrictions — Cursor, Copilot, whatever they use. The extension invisibly records the full developer-AI dialogue: prompts, suggestions, overrides, diffs.
