Stop sorting through unqualified applicants. Underdog.io delivers a curated batch of pre-screened, full-time full stack developers directly to your inbox every Monday. Every candidate has been hand-reviewed. None of them are on Upwork.
The problem with hiring full stack developers
Post a full stack developer job on LinkedIn or Indeed and you'll get 400 applications. Maybe 20 are worth reading. Maybe 5 are actually interested in your company. The problem isn't finding full stack developers — it's finding the ones who are genuinely good, genuinely interested, and genuinely available.
The average software engineering role receives 250+ applications. Sorting through them manually costs your team weeks before a single interview happens.
Traditional recruiting firms charge 20–25% of first-year salary — $30K–$50K for a senior full stack developer hire. And they're often sending you the same candidates as three other companies.
Freelance platforms like Upwork and Toptal are built for contractors. The best full-time full stack developers aren't there — they're already employed and not applying to job boards.
Underdog solves all three. We pre-screen every candidate so only the top 5% reach you, we charge half what agencies charge, and every developer in our network is seeking a full-time permanent role — not a freelance gig.
How it works
No sourcing sprints. No recruiter phone calls. No job posting management. Just a curated batch of pre-vetted full stack developers delivered directly to you each week.
Share your stack, seniority requirements, team size, and what you're building. Takes 15 minutes. We set up your company profile and start matching immediately.
Every Monday, we introduce you to a curated batch of full stack developers who match your criteria. They've been hand-reviewed, they're actively looking, and they already know about your company.
Request interviews directly through the platform. We handle the introduction — you handle the conversation. No agency sitting in the middle taking a cut of everything.
Hiring guide
The best full stack developers for startups aren't always the ones with the longest resume. Here's what actually matters when you're making this hire.
Salary expectations
Base salary only. Equity is additive — particularly significant at seed and Series A. Traditional recruiting agencies charge 20–25% of first-year salary to fill these roles. Underdog charges 11.5%, pay-per-hire only.
How we compare
Every option for hiring a full stack developer has a trade-off. Here's an honest look at how they compare for a startup making a full-time hire.
What hiring teams say
Talentpluto quickly helped us fill the pipeline with high quality candidates. We were able to fill the opening with someone we were really excited about in just a few weeks. We'll definitely work with their team again.
In our first week we interviewed 6 candidates and less than 2 weeks later we signed an absolute killer as our founding AE. Underdog instantly opened up a much larger pool of top candidates than we had access to before.

Pricing
A traditional agency charges 20–25% of first-year salary. For a $160K senior full stack developer, that's $32–40K — before you even know if the hire works out. Underdog is different.
