Fractional CTO Services
Strategic technology leadership, without the overhead
Executive-level technical guidance for companies ready to scale thoughtfully - engaged precisely when and how you need it.
Claverton 42 provides fractional CTO and interim technology leadership services to UK startups, scaleups, and established organisations.
A fractional CTO provides executive technology leadership on a part-time or temporary basis
You gain the strategic insight of a seasoned technology executive—someone who has built and scaled engineering teams, architected enterprise systems, and navigated the complex intersection of technology and business - without committing to a full-time salary.
This model is designed for growing companies that have outpaced DIY solutions but aren't yet ready for a six-figure executive hire. The engagement flexes with your needs; intensive during critical periods, lighter during steady-state operations.
The result is informed decision-making at every level-from daily technical choices to multi-year roadmap development, grounded in decades of real-world experience.
