Every platform ranking above this one sends you contractors, freelancers, or offshore engineers on monthly billing. Underdog.io delivers something different: pre-screened, full-time developers who want to join your team, own their domain, and still be shipping for you in three years. No hourly rates. No monthly subscriptions. No offshore.
The model question
Contract and freelance developers solve a specific problem — you need capacity now, for a defined scope, and you'll be done. Most startups actually need something different: developers who accumulate context about your product, own their domain with judgment, mentor whoever comes next, and make architectural decisions they'll live with for years. That's a full-time hire. And finding one requires a completely different process than posting on Upwork.
Underdog delivers pre-screened developers who are actively exploring full-time roles at startups — introduced directly to your team, matched to your stack and stage. You only pay when you make a hire.

Every Monday, we introduce you to engineers who match your criteria. Hand-reviewed, not algorithm-filtered. Full-time seeking. Already interested in startups like yours before the first message.
Request interviews directly. No agency in the middle. No exclusivity. You pay 11.5% of first-year salary only when you make a hire — zero cost if you don't.
How we compare
Pricing
Traditional agencies charge 20–25% of first-year salary, often as a retainer before you've seen a single candidate. Underdog charges 11.5%, pay-per-hire only. The math is simple: on a $160K senior engineer, that's $18.4K instead of $32–40K — with no risk if you don't hire.
Base salary ranges at US venture-backed startups. Equity is additive. Sources: Wellfound, Glassdoor, Levels.fyi 2025.
