TL;DR: Going from freelancer to agency is a positioning problem before it is an operations problem. Pick a niche, charge premium, hire seniors only.
The three inflection points
- Niche down. "Web development" is not a niche. "Premium Next.js for B2B SaaS" is.
- Productize delivery. Fixed-scope sprints with clear deliverables beat hourly billing every time.
- Hire only seniors. One senior at $80/hr beats three juniors at $25/hr on output, quality, and margin.
