Verified builder network.
Real work. Not resumes.

Upswell replaces the resume-and-inbox cycle with live Git telemetry, peer attestations, and a double-blind trust layer, built for the working engineer, not the platforms farming them.

cold outreach
01

You don't apply. Neither do bots.

There is no inbound funnel to manage. Instead of collecting keyword-stuffed resumes, founders explore live, authenticated engineering history. Discovery replaces pipeline triage.

02

No cold outreach. No inbox clutter.

Conversations require mutual structural fit — neither side can cold-pitch the other. Upswell stays quiet until a role and a builder line up, then automates the introduction.

03

Anonymous by default.

The code speaks first. Names, employers, and GitHub handles stay private, so both sides evaluate on real output. Identities reveal only after a mutual match.

02 / the pass

Two passes, built on one schema.

Build and Role map to the exact same six axes. The role describes the spec; the build is shaped by real engineering history — same structure, opposite ends.

Build Pass

Control your technical passport.

No form-filling, keyword optimization, or ghosting. Your Build Pass verifies your real-world technical signature straight from your Git log while keeping your identity fully private.

Automated Git Telemetry · Un-alterable

Build Pass
Role Pass

Same six axes — the role maps the spec, the build is shaped by real history. The match is the overlap.

03 / signal, deconstructed

A score you can't, and shouldn't have to, write yourself.

Your pass builds itself directly from your live engineering history, so you never write another resume. Connect GitHub once, and our double-blind architecture visualizes your true depth while fully protecting your identity.

Composite score
8.4/ 10

Recomputed on every push — a single number that folds all four signals below into one GitHub-verified score.

04 / control center

Two workspaces. One zero-trust network.

The platform is completely double-blind until an engineer's actual code history matches a company's real workload requirements. Profiles and identity details are strictly locked behind an automated matching perimeter, revealing data only when both sides mutually opt-in.

06 / why upswell

Every other tool was built for a different problem.

Recruiters optimize for placement fees. Job boards optimize for volume. Neither was built for a seed-stage founder hiring their first engineers.
