How much does a fractional CTO cost?

Typically $3,000–$15,000 per month, or about $150–$400 per hour, for 5–20 hours a week. That's far below a full-time CTO, who can cost $200,000–$350,000+ in base salary plus equity.

What are the main types of fractional CTO?

Fractional CTOs tend to specialize: pre-product/MVP (stack and first build), scaling (architecture and team as you grow 10→50), legacy turnaround (tech debt and reliability), AI/ML, and security & compliance.

What is the difference between a fractional CTO, a full-time CTO, and CTO-as-a-Service?

A fractional CTO embeds part-time and owns your technical strategy and team. A full-time CTO does the same full-time at a much higher cost. CTO-as-a-Service bundles CTO-level oversight with an outsourced dev team from one vendor.

When should a startup hire a fractional CTO?

Common triggers are making early technical and stack decisions, scaling an engineering team past the founder's reach, fixing a stalled or fragile codebase, or needing senior technical leadership while you search for a full-time CTO.

Can a fractional CTO run technical due diligence?

Yes — an experienced fractional CTO is a common choice for technical due diligence on behalf of investors or acquirers, assessing architecture, security, the team, and technical risk before a deal.
