What is a Fractional CTO?
A fractional CTO is a senior technology executive who provides strategic technology leadership on a part-time or project basis. Unlike full-time CTOs, fractional CTOs work with multiple companies, offering high-level expertise at a fraction of the cost of a full-time hire.
This model has become increasingly popular as companies realize they need expert technology guidance but may not have the budget, workload, or growth stage to justify a full-time executive position.
