The Non-Technical Founder Challenge
Building a tech product without a technical co-founder is challenging but increasingly common. Non-technical founders need someone to validate technical decisions, evaluate developers, and ensure the product is built right. A fractional CTO fills this gap, providing senior technical leadership without requiring a full-time hire or giving up significant equity.
Non-technical founders typically start with 0.5-1 day per week of fractional CTO time. This increases during key periods: major architecture decisions, hiring sprints, or fundraising. The fractional CTO acts as your technical advisor and quality backstop, not a replacement for day-to-day development resources.
