Technical advisor: the lightest hire a non-technical founder can make
A field guide on what a technical advisor actually does for a non-technical founder, what 0.25–1% equity buys, the three failure patterns, and the four conversations to have before signing.
A founder called me on a Friday afternoon, three weeks out from a decision deadline. She had three proposals for the build of her product on the table: $94K from a Brazilian software house, $145K from a Polish team, $230K from a New York agency. The numbers were different. The timelines were different. The proposed stacks were different. Her runway said she could afford one of them, comfortably. She could not afford the wrong one.
She had spent the week reading the three proposals back to back. She knew what each said. She did not know which one was right. The architecture sections might as well have been in another language. The timelines were quoted with confidence that she had no way to evaluate. The references for two of the three were companies she did not recognize. She told me she had not slept in four days.
“I think I need to hire a fractional CTO,” she said.
“You don’t need a CTO,” I said. “You need a thirty-minute call with someone who has built this kind of system before, who you can show all three quotes to, and who can tell you which of the three is being honest. That’s a technical advisor. You can probably have one signed by Tuesday.”
That call is why this article exists.
What is a technical advisor?
A technical advisor is a senior engineer or technical leader who, in exchange for a small equity grant (typically 0.25% to 1%) and no salary, makes themselves available to a founder for periodic conversations about technical decisions the founder cannot make alone.
They don’t ship code. They don’t manage your engineers. They don’t sit in your standups. They aren’t on the call when you negotiate with vendors, unless you explicitly bring them in. They aren’t accountable for delivery. They don’t have a title on your investor deck.
What they are is the person on the other end of a Slack channel, or a monthly call, when something happens you don’t know how to read. A vendor proposal. A stack decision. A hiring decision. A bug your developer says will take three weeks to fix. A pitch from a “consultant” who wants $40K up front. The kind of question that, asked in the wrong way, lands you with the wrong answer for six months.
That is the hire. Not a leader, not a builder. A second opinion that has the right context, on call, at a price you can afford.
If you are a non-technical founder running a company with one developer (or no developer), an advisor is the cheapest insurance against the three things that keep you up at night: you don’t know how to brief a developer, you don’t know whether a quote is fair, and you have no way to read whether the technical work being done for you is good or bad. A real CTO would solve all three. A real CTO is not available to you yet, and probably shouldn’t be your move at this stage anyway. A technical advisor solves enough of the problem to keep you from making the worst-case decision.
What does a technical advisor do?
Three things, in order of how often they actually come up.
They review the work other people are quoting you. This is the highest-leverage use of an advisor’s time. You send them a software house’s proposal, a freelancer’s quote, an internal estimate from a developer you trust but cannot verify. They read it. Within twenty minutes they can tell you whether the line items make sense, whether the stack is reasonable for what you’re building, whether the timeline is honest, whether the team’s references are people they recognize. You cannot do this on your own. They can, because they have built or quoted on the same kind of work fifteen times before.
They sit in on technical decisions you would otherwise have to make alone. Choosing between two database options. Deciding whether your internal tool should be built or bought. Reading the risk in a proposed integration. Should you accept the developer’s recommendation to rewrite the auth system? These are decisions where the right answer depends on five pieces of context the founder doesn’t have. An advisor with the context can compress a week of confusion into a forty-minute call.
They open doors. Less often, but real. The advisor knows a senior engineer who’s between roles, a software house they personally trust, a recruiter who works with founding engineers, an investor in the same stage who’s seen a similar problem. Their network is part of what you’re paying for. The good advisors offer this without being asked. The mediocre ones treat it as something to ration.
What they do not do, and should not do, is run your engineering team. They do not write your specs. They do not sit on calls with your customers. They do not own deliverables. They do not have hire-and-fire authority. The moment a technical advisor starts to act like a real CTO, one of two things is happening: either they’re being underpaid for the work they’re doing, or you’re using them as cover for decisions you should be making yourself. Both end the relationship within six months.
Technical advisor vs CTO vs fractional CTO: which one do you actually need?
This is the question most non-technical founders skip, and it’s why so many advisor relationships end badly. The three roles sit on a spectrum and look similar at the edges, but they are not interchangeable.
A CTO is a full-time executive. They run the engineering organization, sit on the leadership team, attend board meetings, sign on the architecture, and are accountable for the company’s technical reputation. Their compensation is full salary plus meaningful equity (often 5% to 10% if joining pre-seed). Most non-technical founders at the seed stage cannot actually hire a real CTO, and trying to do so usually produces an overqualified IC or an underqualified executive.
A fractional CTO is a part-time hands-on technical leader who is paid in cash, typically $200 to $400 an hour or a monthly retainer of $5K to $15K. They write specs, review code, hire engineers, manage vendors, and own outcomes for the period you have them. They are the right hire when there is already a build happening and you need someone qualified to oversee it.
A technical advisor is none of that. They are paid in equity, not cash. They do not own outcomes. They are not part of your standup, your sprint, or your hiring loop. They give you their judgment, on call, when you need it. The total time commitment is one to four hours a month on average, with occasional spikes when you’re making a big decision.
The decision tree, in plain language: if there is no product yet and no engineer yet, you need either a fractional CTO to ship the first version or a founding engineer to own the build, plus an advisor for second opinions. If there is a product, an engineer or vendor building it, and your job is to oversee the build well enough to know when something is going wrong, you need an advisor and maybe a fractional CTO. If there is an engineering team of four or more and the company has product-market fit, you are in CTO territory.
Most non-technical founders we work with are in the second bucket. Almost none of them have an advisor in place. That gap is what this article is about.
How much equity should a technical advisor get?
The standard range is 0.25% to 1%, vesting over one to two years with no cliff or a short cliff, in exchange for a defined time commitment.
Inside that range, the actual number moves with three levers.
The first is the time commitment. An advisor who commits to one monthly thirty-minute call sits at the low end. An advisor who commits to a weekly call plus an open Slack channel plus first-call review of every major hire sits at the high end. We typically see 0.25% for the light arrangement, 0.5% to 0.75% for the medium, and 1% for the heavy involvement. Above 1% you are no longer hiring an advisor; you are hiring a fractional CTO and underpaying them in equity.
The second is the stage. Pre-seed equity is more expensive to give. An advisor coming in pre-seed, when the company is genuinely risky, can reasonably expect more equity than an advisor joining post-Series A. The reverse is also true: an advisor who joins after the company has product-market fit and a real valuation is giving up less optionality, and the grant reflects that.
The third is the named value the advisor adds. An advisor whose name on your deck unlocks an introduction to a key investor, or whose reputation among engineers makes recruiting easier, can ask for more. A more anonymous advisor whose value is purely the calls cannot.
Two things to avoid.
First, no cash. A technical advisor is paid in equity. The moment they ask for cash, you are either looking at a fractional CTO conversation or at someone who is not actually an advisor. Real advisors who want a relationship with your company are happy to be paid in equity, because the upside if the company works is meaningful and the downside if it doesn’t is a few hours a month they were going to spend on something less interesting anyway.
Second, no equity without vesting. A short vest is fine (one to two years). No vest is a footgun. We have watched a founder give 1% to an advisor on a handshake; the advisor was on three calls in the first quarter, went quiet, and three years later the cap table still showed the grant when the company raised a Series A. Vesting protects you, not the advisor. The good advisors will not flinch when you ask for it.
For the agreement itself, the Y Combinator FAST (Founder Advisor Standard Template) is a good starting point. Most early-stage tech advisors will recognize it and know how to read it. It exists because the advisor-founder relationship is common enough that the standard terms are a known commodity.
The three failure patterns
We have seen three ways an advisor relationship goes wrong. Watch for them.
Failure one: the advisor as a shield. The founder uses the advisor as cover for decisions they should be making themselves. Every time a hard call comes up, the founder goes silent, waits for the advisor’s monthly call, and then claims the advisor told them what to do. The advisor gets tired of being asked to ratify decisions instead of being asked to weigh in. The relationship dies, and the founder is left with the same decision problem and 0.5% less equity. The fix is to treat the advisor as a consultant on the calls you have to make, not as the person who makes them.
Failure two: the advisor with no skin in the game. The advisor agreed to the role at the seed dinner, accepted the equity grant, and now responds to Slack messages three days late, when they respond at all. This is almost always a result of the founder not setting a real time commitment in the agreement. The advisor said yes to a vague ask, gets pulled into more interesting things, and the founder is too uncomfortable to push back because they’re not paying cash. The fix is structural: a defined cadence in the agreement, a defined response time, and a clear conversation if it slips for two months in a row.
Failure three: the advisor pointed at the wrong problem. The founder hired an advisor with deep expertise in distributed systems. The actual decisions the founder needs help with are vendor selection and developer hiring. The advisor’s value-add on the technical decisions is real but rare; the founder’s actual pain is in the operational decisions where the advisor has no advantage over a sharp generalist. The fix is to be honest about what kind of help you need before you start the search. A non-technical founder running a vertical SaaS company will, in our experience, get more out of an advisor who has built two or three real products in production than an advisor who is the deepest expert in a specific subfield.
The four conversations to have before signing
Before the equity grant lands on paper, work through four things in conversation. None of these is contentious if the advisor is the right fit. All four become friction if the fit is wrong, which is exactly the value of having them upfront.
Conversation one: what is the actual help you need? Not “general technical guidance.” Specific. Is it reviewing vendor proposals? Is it sitting in on the first engineer hire? Is it monthly architecture review? Is it being the named person you call when something is broken? Write down the three things, in order, that you expect to ask the advisor about most. Show them the list. A good advisor will tell you within ten minutes whether they’re the right fit for that list. A bad advisor will say yes to everything.
Conversation two: what is the time commitment, on what cadence? Get specific. One thirty-minute call per month, plus async Slack response within forty-eight hours, plus availability for two ninety-minute “deep-dive” sessions per year. Or whatever fits the scope. Vague time commitments are the single most reliable predictor of an advisor relationship that dies in six months.
Conversation three: what is the equity, on what vesting? Pick a number in the 0.25% to 1% range, with a vest of one to two years. Put it on paper. Use the FAST template or a lawyer-reviewed equivalent. Do not hand over equity on a handshake.
Conversation four: what is the offramp? What happens if either of you decides this isn’t working? If the advisor goes quiet for two months, what’s the conversation? If the founder pivots and no longer needs this advisor’s expertise, what’s the conversation? The good advisor will be the one who insists on this conversation. The advisor who flinches at it is the advisor you do not want.
How to find a technical advisor
In rough order of how often it works.
Your investor’s network. Seed-stage investors meet hundreds of senior engineers and former CTOs every year, many of whom advise multiple companies in the investor’s portfolio. Ask your lead investor for two introductions. They will know who is currently advising, who has bandwidth, and who has been recommended for the kind of work you need.
The early team of a company in your domain. The first three engineers at a now-Series-B company in your vertical know your problem space, were on the build five years ago, and are often open to advising the next generation. They are not actively shopping for advisor roles, which is good for you. A cold message that names a specific decision you’re facing and asks for thirty minutes works more often than founders expect.
The deliberately senior cold pitch. A blog post you read three times, a podcast episode that made you nod, a GitHub repo whose code reads cleanly to you (or to your developer). Reach out. Explain the specific decision. Offer the standard equity arrangement. Senior engineers who have already been advisors before will know in two minutes whether they want to take the call. The hit rate is low but the cost of the message is low.
Your competitors’ ex-team. Engineers from a competitor that closed, was acquired, or pivoted away from your space have exactly the right context and are usually amenable to a structured relationship. The conversation is slightly more delicate, but if you handle it cleanly the fit is excellent.
What does not work: posting on LinkedIn, generic startup advisor marketplaces, or asking your accelerator’s general Slack channel. The advisors you want are not browsing for opportunities. They are responding to specific asks from founders who already did the work to figure out what they need.
What good looks like, six months in
If the advisor relationship is working, six months in the founder can describe three specific calls where the advisor’s input changed a decision. Not vibes, not “they’re a great sounding board.” Three specific decisions where the founder was about to go one way, the advisor pushed back with context the founder did not have, and the founder went the other way.
The cadence is regular. The advisor responds. The founder is not surprised when something the advisor warned about comes up later.
The equity has vested incrementally, and neither side has felt that the equity is mispriced relative to the work being done. If either side has been quietly resentful, that is a signal to renegotiate or end the relationship.
The advisor has introduced you to at least one useful person. Not necessarily a hire, not necessarily an investor. Someone whose existence you didn’t know about who turned out to matter.
If three of those four things are true, you are getting roughly what 0.5% buys. Renew the relationship for another vesting period if both sides want to continue. If only one or two of the four are true, the relationship is underperforming, and the conversation to have is the one in failure pattern two.
When you should not hire a technical advisor
Three situations.
You do not yet have a product and you do not yet have an engineer. In that case, an advisor is the wrong shape of help. What you need is a fractional CTO or a founding engineer who will actually build the first version, plus possibly an advisor as a second opinion on the build. The advisor cannot ship for you.
You have one developer and you have not yet learned how to brief them properly. In this case, an advisor’s marginal value is real but small compared to fixing the briefing problem at the source. The two are not mutually exclusive, but the advisor will not save you from a broken briefing process.
You think you need a CTO and you are using “advisor” as a cheaper title. This is the path that produces a frustrated founder, a confused advisor, and an underperforming engineering function. If you genuinely need executive oversight, hire a fractional CTO for three to six months and revisit the question after.
If none of those three apply, an advisor is almost certainly the right move. The cost is low, the upside is high, and the worst case is that you and the advisor part ways amicably after a vesting period with no real damage done.
Frequently asked questions
Do technical advisors get paid?
In cash, no. In equity, yes. The standard arrangement is 0.25% to 1% equity vesting over one to two years, in exchange for a defined time commitment. The reason advisors accept this is that the upside in equity, if the company works, is meaningfully larger than they would make at hourly consulting rates over the same period. The reason founders should accept this is that an advisor paid in cash is no longer an advisor; they are a consultant, and the conversation about cost will dominate the relationship.
How is a technical advisor different from a co-founder?
A co-founder owns the company. They sign the docs. They share founder-level risk: low or no salary in the early days, founder-level equity (typically 10% to 50% depending on stage and contribution), founder-level vesting (four years), and founder-level voice. A technical advisor is none of that. They have a small equity grant, no operational role, no founder rights, and no liability. Founders sometimes try to blur this line by giving an advisor a co-founder title without the equity or the rights. It always ends badly. Pick the structure that matches the relationship.
How long do advisor relationships last?
The vesting period is the structural answer: one to two years. The relational answer is that good advisor relationships sometimes outlast the vesting and turn into something else. The advisor becomes a board observer. They take a small angel check. They re-up for another vesting period at a lower percentage. Bad advisor relationships often end before the vesting completes, which is what the cliff is for. Plan for one to two years; let the relationship tell you what comes next.
Should I have more than one technical advisor?
Sometimes. If the technical decisions you face span two clearly different areas (e.g. you have a fintech product where the build is straightforward but the regulatory technical landscape is its own discipline), two advisors with non-overlapping expertise can each give 0.25%-tier time and value. Three or more is almost always a mistake; the cap table gets noisy, no advisor feels primary, and the founder ends up coordinating advisors instead of getting advice.
Will an advisor replace a fractional CTO?
No. The advisor gives you judgment, on call, at a low total time commitment. The fractional CTO owns the build. They are complements, not substitutes. The right pattern at the seed stage for many of the non-technical founders we work with is a fractional CTO for the first six months of the build, transitioning to a technical advisor once the build is stable and the engineer-or-vendor relationship is running well. That progression is cheaper, lower-risk, and more aligned with the actual shape of the work than trying to make a single hire cover the whole arc.
