Definition
Quick Definition
A Fractional CTO (Fractional Chief Technology Officer) is an experienced technology executive who works with companies on a part-time or contract basis, typically 1-3 days per week, providing strategic technology leadership without the cost of a full-time hire.
What is a Fractional CTO? Understanding the Role
The fractional CTO meaning centres on flexible, senior-level technology leadership. Unlike traditional full-time CTOs earning £150,000-£250,000 annually, a fractional Chief Technology Officer works with multiple companies simultaneously, dedicating typically 1-3 days per week to each client. This model emerged from the startup ecosystem where companies need CTO-level expertise but cannot justify or afford a full-time executive.
