The Build Decision That Determines Your Runway
Agency or in-house? This decision determines how fast you ship, how much runway you spend, and whether you have technical leadership driving product vision. It's not a permanent choice, but the wrong choice at the wrong stage is expensive.
True Cost Comparison
In-house senior full-stack developer (US): $150K–$200K salary + $30K benefits + $20K recruiting + months to hire = $200K+ per year, 3–6 months before productivity.
Quality agency (offshore): $8,000–$20,000 for an MVP, $5,000–$15,000/month ongoing. Starts in 1–2 weeks. Full team (PM, designers, developers, QA).
For a $1M seed, hiring in-house costs 2 engineers for 1 year. An agency can ship your full product in 3 months, leaving 9 months of runway to iterate based on real user feedback.
When In-House Wins
- Your core competitive advantage is the software itself (not the business model or distribution)
- You need to ship continuously, 5+ times per week
- Post-PMF, predictable growth stage where iteration speed matters
- You have technical co-founders who can lead and evaluate the team
When Agency Wins
- Pre-PMF, testing ideas quickly
- Non-technical founders who can't evaluate in-house developers
- Specific expertise needed (AI/ML, mobile, compliance) not worth full-time hire
- Budget constraints: need full team but can't afford US hiring costs
The Hybrid Model
Many successful startups use agencies to build the MVP, then hire 1–2 in-house engineers to take over and iterate, with the agency available for specialized work. This gives you speed to market plus the institutional knowledge that comes from in-house ownership.
