# GradPipe > GradPipe is an engineering hiring network that matches startup founders to engineers by the work they can prove — analyzing the whole builder record (GitHub down to the syntax tree, shipped systems, portfolio, resume, and LinkedIn) instead of credentials. ## Main - [About GradPipe — hiring engineers by proven work](https://gradpipe.com/about.md): How GradPipe scores engineers across GitHub (down to the syntax tree), shipped systems, portfolio, resume, and LinkedIn — and what makes the approach different from LeetCode-style platforms. - [How GradPipe works — AST-level engineering signal](https://gradpipe.com/how-it-works.md): Detailed explanation of how GradPipe reads the whole builder record and analyzes public code at the AST level to measure engineering signal. - [For Founders — hire senior engineers by craft](https://gradpipe.com/for-founders.md): How startup founders use GradPipe to hire senior engineers who do not apply to job posts — three matches per role, direct introductions, no ATS. - [For Engineers — be found by what you’ve shipped](https://gradpipe.com/for-engineers.md): How engineers join the network and get matched with startups by the work they can prove. Roles come to you; your work is the evaluation. ## Placements and case studies - [Case study: founding engineers for Independence OS](https://gradpipe.com/case-studies/independence-os.md): How GradPipe opened the IIT Bombay and IIT Kharagpur pipelines for Independence OS (healthcare AI) and placed several founding engineers. - [Case study: SWE interns for Unsiloed AI (YC F25)](https://gradpipe.com/case-studies/unsiloed-ai.md): How GradPipe sourced strong software-engineering interns for Unsiloed AI (YC F25). - [Case study: founding engineer for Stellon Labs](https://gradpipe.com/case-studies/stellon-labs.md): How GradPipe sourced and placed a founding engineer for Stellon Labs (infrastructure for machine learning). ## FAQ and Reference - [Pricing — GradPipe success-fee model](https://gradpipe.com/pricing.md): GradPipe’s success-fee pricing model and how it compares to traditional contingency and retained search. - [GradPipe FAQ — scoring, pricing, and process](https://gradpipe.com/faq.md): How AST scoring works, why GradPipe doesn’t use LeetCode, what makes a candidate elite, pricing, the placement process, and privacy.
