Signs You Need a Fractional CTO

Your technical debt is mounting. Without strategic oversight, development teams can accumulate technical debt that slows down innovation and increases costs exponentially. A fractional CTO identifies these issues early and implements solutions before they become critical.

You're struggling to scale your tech team. Hiring developers is expensive and time-consuming. Are you hiring the right people? Building the right architecture? A fractional CTO ensures you build a high-performing team with the right skills, culture, and processes from day one.

Critical situations where a fractional CTO delivers immediate value:

Raising investment rounds (investors want to see technical competence)
Building your MVP or preparing for product launch
Scaling from 5 to 50+ developers
Migrating legacy systems or re-platforming
Implementing DevOps, security, or compliance frameworks
Navigating technical due diligence during acquisitions

Fractional CTO Cost vs. Full-Time CTO

Full-time CTO costs are skyrocketing. In 2025, experienced CTOs command £120K-£180K+ base salary, plus equity (often 2-5%), benefits, bonuses, and recruitment fees. Total first-year cost easily exceeds £200K.

Fractional CTO services deliver the same expertise at a fraction of the cost. Access world-class technical leadership for £3K-£8K per month depending on engagement level—saving you over 60% compared to full-time hires while maintaining flexibility.

Better ROI, zero retention risk. Scale up or down based on your needs, avoid expensive recruitment mistakes, and get immediate access to 15+ years of battle-tested experience across multiple industries and technologies. Start fast, deliver results, move forward.
