How it works

You're not applying.
You're being introduced.

This isn't a job board. No listings to scroll, no cover letters to write, no applications to track. Here's how it actually works.

01
Build your profile

Tell us where you've been and where you want to go. Takes five minutes. No resume upload required.

02
Get selected

We review every profile by hand. Only the top 5% make the cut — which is exactly why companies trust our introductions.

03
Companies reach out

Hiring managers at vetted NYC startups contact you directly. You decide who's worth your time. 85% of accepted engineers hear from a company in their first week.

Why this is different

The job board sends you into a pile.
We put you at the top of one.

When a company gets an Underdog introduction, they're not sorting through 400 applicants. They're reading a curated shortlist. You're a recommendation, not a resume.

Typical job board
✗Apply to a posting and compete with hundreds of other applicants
✗Your resume disappears into an ATS no one's actively checking
✗Recruiters from agencies you've never heard of reach out
✗No signal on comp until late in the process
✗Your current employer can find your profile
Underdog.io
✓One profile, introduced to multiple companies at once
✓Hiring managers read your profile directly — no ATS in the way
✓Only vetted companies — we turn away 50%+ who try to join
✓Salary ranges shared upfront with every intro
✓Your profile is hidden from your current employer by default
