Fractional CTO in Lisbon: Guide [Save €100K+/Year]
Why hiring a full-time CTO is often the wrong move for startups under 2M ARR. The fractional CTO model explained with real examples from Lisbon.
You have a great product idea, early traction, maybe even some revenue. But you are not ready to commit 120,000 to 180,000 euros per year to a full-time CTO. The majority of startups in Lisbon with fewer than 20 employees do not need a full-time CTO. What they need is fractional CTO services: senior technical leadership on a part-time flexible basis.
What Is a Fractional CTO?
What Is a Fractional CTO?
A fractional CTO provides the same strategic technical leadership as a full-time CTO but works with your company on a part-time or project basis. Typically 10-20 hours per week. They handle technology strategy, architecture decisions, team hiring and management, vendor selection, security, and technical due diligence for fundraising. You get C-level technical expertise without the C-level salary. Porto-based leadership consultant Hélder Teixeira makes a similar point in his book O Último Activo: a title like CTO only matters if someone still governs the decision behind it. The fractional model works when the founder keeps that governing role and uses the hire to sharpen the call.
