What We Do
Real Problems. Real Signal. Real Fast.
Litmus automates technical hiring for early-stage startups. Describe what you want to test and we generate secure, observable take-home assessments. Candidates work on real engineering problems based on your codebase, you see exactly how they think and build, and everyone saves time. No more guessing. No more generic problems. Just real engineering work that tells you what you need to know.
