What Does a CTO Actually Cost? Real Startup Salary Data for 2026

Let's cut through the noise. You're building something. You need technical leadership. And you've probably spent an embarrassing amount of time Googling "startup CTO salary" trying to figure out if you're supposed to pay someone £40k or £400k.

The truth is messier—and actually more interesting—than any salary range table suggests.

We've worked with dozens of founding teams across different stages, industries, and geographic locations. We've hired CTOs ourselves, become CTOs for others, and watched countless founders wrestle with this exact decision. This is what we've learned.

The Stage-Based Reality: CTO Salary by Funding Level

Your startup's stage isn't just about funding amount—it fundamentally changes what a CTO costs and what they're willing to accept.

Pre-seed and bootstrap phase (£0 external funding):

This is where equity becomes currency. Most pre-seed teams either don't have a technical cofounder, or they do but everyone's working for free or near-free. If you're hiring someone into this phase, you're not really hiring a CTO—you're recruiting a cofounder.

The structure usually looks like: tiny base salary (maybe £20k-£30k, if anything) plus 5-15% equity. Sometimes it's all equity. The person joining at this stage has to believe they're building something genuine, not just optimizing someone else's vision.

Seed stage (£500k-£2m):

This is where proper CTO salaries actually start. You have runway, you can pay real money, but you're still capital-constrained. Expect to pay:

London:: £75k-£95k
South Wales/Yorkshire/regional UK:: £60k-£80k

Add 1-3% equity to this. The equity component is significant here. At seed stage, you're still betting on something unproven. The salary alone won't attract senior technical talent—but salary plus meaningful equity and the chance to build something real, will.

Total compensation including equity run-up: think of it as £85k-£110k in London, £70k-£95k regionally.

Series A (£2m-£10m):

You've found product-market fit signals. Your CTO isn't debating whether this might work anymore—they're scaling what works. Salaries climb significantly:

London:: £95k-£130k
Regional:: £85k-£115k

Equity is usually 0.5-2%, though this compresses as your cap table gets busier. You'll also start seeing proper benefits packages emerge here: healthcare, pension matching, conference budgets.

Series B and beyond (£10m+):

At this point, you're competing for experienced operational talent. CTO salary floors look like:

London:: £130k-£180k
Regional:: £110k-£150k

Equity typically 0.2-1%. But you're now offering what proper tech companies offer: signing bonuses, performance bonuses, proper equity acceleration, the works.

The Location Premium: Why London Costs 20-30% More

This isn't secret. London draws talent from across the UK and Europe. Market pricing reflects that. A CTO in London commands 20-30% premium over equivalent roles in regional UK cities.

Why? Partly talent density. Partly cost of living. Partly because London startups can raise more, so they can pay more. It becomes self-reinforcing.

But here's what's interesting: if you're not in London and you're competing with London startups, you actually have an advantage. A regional location, lower cost of living, and genuine equity upside can be more attractive than a London salary bump. You just have to be explicit about it.

The Equity Component Is the Real Compensation

This is the bit most founders get wrong.

At seed stage especially, don't think of equity as a nice bonus. Think of it as the actual compensation. A £70k salary plus 2% equity isn't "£70k with a bit of upside." It's a compensation package where roughly 30-40% of the total expected value comes from equity outcome.

If your startup raises at a £10m post-money valuation at seed (reasonable for UK tech), 2% equity could be worth £200k over a 4-5 year vest. That's an extra £40k-£50k annually in expected value. That matters for financial decision-making.

The flip side: if you're asking someone to take equity instead of cash, you need to be ruthlessly honest about what that equity might actually be worth. "We might exit at £50m" is not a compensation plan. "Here's our target market, here's what we've validated, here's why we think £50m is achievable" is better. Then your CTO can actually assess whether that 2% makes sense.

This is why early-stage CTOs either have financial runway (previous exits, family money, or low expenses) or they don't take the role. Equity is option value. Not everyone can afford to hold options.

What Actually Drives CTO Salary Variation

Industry matters more than you think.: Fintech and biotech CTOs command 15-25% premiums over e-commerce or content CTOs at the same stage. Not because the work is harder—because the hiring pool is different and regulatory complexity raises the bar.

Technical complexity.: Building infrastructure for millions of concurrent users is different from building a content site. A CTO managing real-time systems, complex data pipelines, or security-critical infrastructure should cost more. This isn't snobbery—it's market reality.

Team size.: Managing 3 engineers is different from managing 15. At seed you might have a CTO who codes 50% and manages 50%. At Series A, maybe it's 20/80. The managing-through-others component changes what salary tier you're in.

Founder vs. hired CTO.: This is subtle but real. Founder-CTOs often take lower salaries. Hired CTOs—people joining a team where the vision isn't theirs—expect to be properly paid or properly equipped with equity. This is completely fair.

The Fractional CTO Option: When Full-Time Makes No Sense

Not every startup should hire a full-time CTO.

Fractional CTO services (we do this, and so do other firms) typically cost £3k-£8k monthly depending on scope and seniority. Over a year that's £36k-£96k. For a seed-stage startup that needs strong technical governance but not 40 hours weekly of full-time CTO work, this is often a smarter move.

You're hiring fractional when:

You have a strong technical cofounder or VP Eng but need strategic oversight
You need to hire your first engineering team but can't yet justify full-time leadership overhead
You want external accountability and best-practice direction without a full salary commitment
Your runway is tight and you need flexibility

The gap between fractional CTO cost and full-time CTO salary is exactly where hybrid models live. This is something we see more of: £40k-£50k salary plus 2-5% equity, where the CTO is part-time but deeply committed. Works well when you've found the right person who wants portfolio growth or is between exits.

We've written more about when to hire a CTO, how much fractional CTOs actually cost, and fractional vs. full-time if you want to go deeper here.

The Equity-Aligned Hybrid: A Middle Ground That Works

Here's what we've seen work well, especially at seed stage:

£50k-£65k salary + 2-4% equity + flexibility on hours (70% full-time, 30% advisory to other portfolio companies, or similar arrangement).

This works because:

The founder conserves cash relative to market-rate full-time CTO hire
The CTO gets proper equity ownership without taking a massive salary cut
Both parties are aligned on long-term outcome, not just monthly payroll
The CTO stays sharp across multiple businesses and brings that cross-portfolio learning back

This isn't a salary compromise. It's a different structure entirely—one that treats the CTO more like an extended cofounder than like an employee. If the person is right, and the startup is right, it often produces better outcomes than either full-time or fractional alone.

What You Actually Need to Do

Figure out your stage first.: Use the salary ranges above as anchors, but check local comparisons. Levels.fyi and Glassdoor aren't perfect for startups, but they're better than nothing.

Price equity honestly.: Don't use optimistic exit scenarios. Use realistic ones. If your CTO is genuinely in a position to hold options (they have runway), great—equity can be substantial compensation. If they're not, a fractional arrangement or higher salary matters more.

Be explicit about what you need.: "CTO" is umbrella job. Do you need a technical cofounder, or do you need operational scaling leadership? Hiring for the wrong thing is expensive. Read about what a fractional CTO actually does if that's relevant to you.

Consider equity splits carefully.: We've written about technical cofounder equity splits because this is where early mistakes compound. Get it roughly right upfront.

Don't underpay out of hope.: Paying 30% below market because "we're a startup" signals that you don't respect the role. That attracts either juniors (not what you need) or founders desperate enough to gamble everything on your vision (risky). Pay fairly. The cost of hiring the wrong technical leader is higher than the salary difference.

The Real Tension

Founders face a genuine trade-off here. You want to preserve runway. You also need serious technical leadership. Both are real constraints.

The answer isn't "pay whatever." It's "understand the trade-offs and make them consciously."

Fractional CTO services exist because that trade-off is real. Hybrid structures exist because you can often find someone who weighs 70% commitment differently than full-time, especially if equity is genuine.

But if you need a full-time CTO—and most scale-stage startups do—then budgeting for the salary ranges above isn't optional. It's baseline. The question is how you balance base salary against equity, and whether geographic flexibility helps, but not whether to pay.
