Hired to lead your technology function part-time: an ongoing CTO-as-a-service engagement, not a one-off project. Joins your team, attends your meetings, manages your engineers, represents you to investors, and owns the outcomes.
Their job is to make your company successful. Their accountability is ongoing.
Hired to provide expert advice on a specific problem. Analyzes your situation, delivers recommendations in a report or slide deck, and moves on to the next client.
Their job is to be right. Their accountability ends when the engagement ends.
A consultant diagnoses and writes a prescription. A fractional CTO checks the vitals, adjusts the treatment, and stays until you are healthy.

Timing
Cost
$48,000 - $120,000
$200-$500/hour × 20 hours/week × 12 weeks
At the end: a report. Maybe some implemented changes. The consultant moves on.
$15,000 - $45,000
$5,000-$15,000/month × 3 months
At the end: a functioning technology organization, an ongoing relationship, and someone who knows your business deeply.

FAQ
A fractional CTO is embedded in your team, leads engineers, represents your company to investors, and is accountable for outcomes. A consultant provides expert advice, delivers reports or recommendations, and typically has a defined end date with no ongoing accountability.
Fractional CTOs typically charge $5,000-$15,000 per month on retainer for ongoing leadership. Consultants often charge $200-$500 per hour or project-based fees starting at $10,000-$50,000. The fractional model is more cost-effective for ongoing needs, while consulting works better for specific, time-bound projects.
Yes, for most startups from seed through Series A, a fractional CTO can provide the same strategic value without a full-time salary or equity. The fractional model works best when you need senior technical leadership but don't have enough work or budget to justify a $200K-$300K full-time executive salary.
Absolutely. Many clients bring me in as their fractional CTO for ongoing leadership, then hire specialized consultants for specific projects I identify: security penetration testing, FinOps optimization, regulatory compliance. The fractional CTO is the general contractor; consultants are the specialists brought in for specific jobs.
