How to hire a CTO, starting with which kind you actually need
To hire a CTO, first decide which job it is: a founding CTO who builds the product, a scale-up CTO who builds the team and platform, or a transformation CTO who modernises a larger company. Each sits in a different pool. Source directly, test technical judgment against business outcomes, and have the board meet finalists.
Decide this first
"CTO" names at least 3 different jobs. A search that does not pick one ends up comparing a hands-on builder with an executive who has not written code in 8 years, and nobody can choose.
The 3 kinds of CTO, and where each one works today
| Founding CTO | Scale-up CTO | Transformation CTO | |
|---|---|---|---|
| Company stage | Pre-seed to Series A | Series B to pre-IPO | Established company, often non-tech |
| The job | Writes much of the code and makes the first architecture calls | Builds the team, the platform and the security posture | Modernises legacy systems and the tech org |
| Where they are now | Staff or principal engineers, ex-founders, early engineers at startups | VPs of Engineering, CTOs of smaller companies, acquired founders | CIOs, CTOs and VPs at large companies or consultancies |
| Equity versus cash | Mostly equity | Balanced | Mostly cash |
| Common mistake | Hiring an executive who cannot build | Hiring a builder who will not delegate | Hiring for buzzwords over delivery history |
These are patterns from practice, not fixed categories. Pick the column that matches the next 2 years.
Where to find CTO candidates
Founding CTOs rarely carry the title yet. Look for staff and principal engineers who have shipped products end to end, early engineers at startups that were acquired, and founders whose last company wound down. Open source maintainers and people who write about architecture in public are easy to research before you write.
Scale-up CTOs are mostly VPs of Engineering ready for the wider remit, or CTOs of smaller companies looking for a bigger stage. Founders of acquired companies become reachable when their retention period ends, which a profile's tenure dates often hint at. Your investors see many portfolio CTOs and can tell you who is restless.
A brief and a Boolean string for a scale-up CTO
Adapt the brief to the column you chose above. The Boolean version trades recall for control.
Plain-English brief:
CTO or VP of Engineering who has led engineering through a Series B or C at a B2B software company, grown the team past 50 engineers, owned security and compliance work such as a first SOC 2, and presented to a board. Still close enough to the code to review an architecture. Europe, remote.
Boolean:
(CTO OR "Chief Technology Officer" OR "VP of Engineering" OR "VP Engineering" OR "Head of Engineering")
AND (SaaS OR B2B OR platform)
AND ("Series B" OR "Series C" OR scale OR scaled)
AND ("SOC 2" OR security OR compliance OR board)
NOT (fractional OR consultant OR recruiter)
Every candidate judged against the brief
Results ranked against the CTO brief, each card with a short reason traced to the profile.
The Cognitive reads the brief into editable filters and judges each person against the must-haves. People who miss one drop below those who meet them, so a founding engineer who never ran a team is still visible, just lower. Tenure per role in the profile panel helps you spot a retention period ending.
What BLS data says about CTO pay
BLS publishes no CTO wage on its own. It names the CTO among the titles in computer and information systems managers, a group with a median of $175,140 in May 2025, usually after 5 years or more of related work. For context, chief executives had a median of $213,990 in the same survey (both read 5 October 2026).
A founding CTO is paid mostly in equity, so these figures tell you little at seed stage. They are more useful for a transformation CTO, where most of the offer is cash. Whatever the stage, decide the equity range before outreach starts, because strong candidates will ask in the first call.
What to assess in a CTO, with questions that get past the pitch
A strong senior engineer and a CTO can give the same technical answer. The difference is whether the answer ends with a business consequence.
Tell me about a technology bet you made that the rest of the leadership team had to live with.
A link to an outcome, such as rebuilding billing because pricing experiments were blocked for months, and how the payoff was measured.
What did it cost, and would you make the same call today?
Walk me through a build versus buy decision, for example authentication or a data warehouse.
Total cost, lock-in risk, and the point at which they would revisit the choice.
How did you grow engineering from a handful of people to several teams?
The first managers they appointed, why those people, and the hiring mistake they would not repeat.
Tell me about a first SOC 2 audit or a serious incident you led the company through.
What they owned personally, what they delegated, and what changed afterwards.
How have you explained technical debt to non-technical founders or investors?
Debt framed as revenue risk and delivery speed, with a real conversation and its outcome.
A CTO hiring process that founders and boards can run
- Pick the kind of CTO and write the mandate Founders and the board agree the column from the table, the 2-year goals and what the CTO owns versus the CEO and product.
- Set the equity and cash range Agree it before outreach. A founding CTO conversation stalls without it, and changing the number mid-search costs trust.
- Source and reach out Search the pool for your column. The first message should come from the CEO and name the problem, not the perks.
- Structured first conversations Score every candidate on the same 5 criteria: strategy, build versus buy, scaling, security and board partnership.
- Review your real system Give finalists a walkthrough of your architecture and ask what they would change in the first 6 months and what they would leave alone. "Here is our stack and our incident log from last quarter. Where would you start?"
- Board, team and references A board member or investor meets finalists, engineers meet them too, and references include people who reported to them.
If you are a non-technical founder hiring your first CTO
Do
- Ask a technical advisor or investor to sit in on the final rounds
- Check shipped products, not only titles and logos
- Agree vesting and decision rights in writing before the start date
- Ask how they would hire the first 5 engineers
Do not
- Hire the most impressive résumé for a hands-on build
- Treat a fractional CTO as a long-term substitute for a team
- Promise co-founder equity before you have worked together
- Skip references because the chemistry feels right
How The Cognitive fits a CTO search
Sourcing is the larger job here. The Cognitive searches ~900M public profiles from a plain-English brief, reveals verified emails and phone numbers for the people you keep, and keeps everyone found with the role so later searches skip them.
For a wide first pass, candidates take a live, two-way AI video interview of 10 or 20 minutes on your criteria. Each is scored 1 to 5 with overall written feedback, a transcript and a recording, and nothing is rejected automatically. The founder and the board still decide. With 60+ ATS integrations, imported candidates get a note written back and their stages never move.
AI Sourcing and AI Interview each start at $99/month.
Probing the claims on a CTO résumé
The AI follows up on what the candidate just said, against a rubric fixed for the role.
Before the interview the AI plans up to 5 resume points to probe, such as "scaled the platform to 10 million users", and asks what the candidate personally led. Each comes back verified, refuted or unclear with evidence. It cannot check outside facts, so references still matter.

Frequently asked questions
How much does it cost to hire a CTO?
It depends on the kind of CTO. A founding CTO is paid mostly in equity. For later stages, BLS has no CTO wage, but the group that includes CTOs had a median of $175,140 in May 2025. Add the cost of a search firm if you use one, which is usually priced against first-year compensation.
How do you find a CTO for a startup?
Look for staff and principal engineers who have shipped a product end to end, early engineers from acquired startups and former founders. Ask investors and advisors for introductions, research open source and public writing, and source directly rather than posting and waiting.
How long does it take to hire a CTO?
No reliable public figure exists for CTO searches, so treat any single number with care. Board involvement, equity negotiation, a system review and references each add stages, and a sitting CTO may have a long notice period. Agreeing the kind of CTO and the equity range up front removes the most common delays.
Should I hire a fractional CTO or a full-time CTO?
A fractional CTO suits a company that needs architecture advice, vendor choices or help hiring its first engineers, but not daily ownership. Once technology is the product and a team needs leading every day, hire full time. Many companies use a fractional CTO to run the full-time search.
What is the difference between a CTO and a VP of Engineering?
The CTO owns technology direction, architecture and often the technical voice with customers and investors. The VP of Engineering runs the organisation: delivery, managers and hiring. Early on one person does both; they split as the team grows.
Should a non-technical founder look for a technical co-founder or hire a CTO?
If the product does not exist yet and cash is short, a co-founder with meaningful equity is the usual route. If you have funding and a product, hiring a CTO with clear vesting and decision rights is cleaner. Either way, get a technical advisor into the final rounds.
Can an AI interview screen CTO candidates?
As a first pass on a wide search, yes. Every candidate gets the same criteria in a 10 or 20 minute conversation they book themselves, with a 1 to 5 score per criterion, written feedback and a recording. The founder, the board and references still decide.
