The best engineers don't apply. They're invisible to every job board, ATS, and recruiter. We find them anyway. GradPipe parses GitHub at the AST level , actual code, not self-reported skills and ranks 1,400+ builders by real technical depth. 15 engineers placed at YC-backed and hard-tech startups in 4 months. Founders get matched candidates before posting a job. No LeetCode. No resumes. No HR theater. Just signal.
