What is a Fractional CTO?
A Fractional CTO is a part-time Chief Technology Officer who provides senior technology leadership, strategy, and execution oversight to multiple companies simultaneously. They provide senior technology leadership part-time, which is often materially lower cost than a full-time CTO hire, depending on scope and market.

Many companies start with fractional CTO and transition to full-time when executive technology oversight is needed continuously and budget supports permanent headcount. Signals can include:
- Team growth increases ongoing executive leadership demand
