How to find a non-technical cofounder when you're the one who builds

This guide is for engineers, designers and other makers who can build a product and need a cofounder who can sell it: a business, sales or go-to-market cofounder. If you're on the other side, looking for someone to build, read how to find a technical cofounder instead.

Technical founders tend to assume this is the easy direction, since plenty of people would happily take the title of business cofounder. Far fewer can find and close customers for a product that doesn't sell itself yet, and those are the ones worth your time. When an engineer at a large tech company asked on Hacker News in 2020 where to meet non-technical cofounders, the most useful replies weren't about where to look at all. They were about trust, and about whether the person had done the work before.

What does a non-technical cofounder actually do?

In most software startups the non-technical cofounder owns everything that happens outside the product. In the first year that usually means:

• Finding customers. Working out who has the problem badly enough to pay, reaching them and getting meetings.
• Selling. Running the calls, handling objections, setting prices and closing the first deals.
• Bringing back what customers say. Early sales are mostly learning. Pete Kazanjy, in his book *Founding Sales*, calls early-stage selling "in large part evangelical product management and product marketing".
• Running the company. Fundraising if you raise, hiring, contracts, finance and the many jobs that have no owner yet.

The title varies. Some people search for a business cofounder, others for a sales cofounder, a commercial cofounder or a go-to-market cofounder. The job is roughly the same: they make sure the thing you build reaches people who pay for it.

The three kinds of non-technical cofounder

It helps to decide which kind you need, because you'll find them in different places.

Many good business cofounders mix two of these. A former operations manager who has also sold software to her old industry is worth more to a vertical product than a sales director from a large software company.

Do you need a business cofounder, or do you need to sell first?

Some founders need a cofounder. Others need to spend a month selling and then decide. Investors and experienced sellers lean towards the founder selling first. Unusual Ventures quotes Hector Hernandez, who has built revenue teams at several software companies: "Founders are almost always the best salespeople, even at large companies." The same post warns that if you can't close the first few deals, a new sales hire will struggle too.

In a 2025 Hacker News thread, a programmer whose product had made a few sales asked how to find a sales cofounder. Several replies said the same thing in different words: do the first sales yourself, call the people who would pay, and ask the customers you already have whom they'd recommend.

There are good reasons to look anyway. The 2011 Startup Genome Report, based on more than 650 self-reported web startups, found that teams with one technical and one business founder raised 30% more money and grew users 2.9 times faster than teams with only one kind of founder (Startup Genome). The data is old and shows correlation, not cause, but it fits what most builders find: selling and building both take full days, and one person rarely does both well for long.

A rough test. You probably need a business cofounder if:

• You've had 15 or 20 conversations with potential buyers and still can't say clearly who buys and why.
• Your product sells to businesses through calls, pilots and procurement, and you have nobody who has done that before.
• You've closed some customers yourself and the product has stopped moving because selling takes all your time.
• You're building for an industry you've never worked in.

If none of these apply, sell for a few more weeks first. You'll be a better judge of a sales cofounder once you know what selling your product involves.

Why good business people turn technical founders down

Good sellers have options. The median US sales manager earned $148,270 a year in May 2025, according to the Bureau of Labor Statistics. The person you want may well earn that, often with commission on top, and will be giving it up to sell something with no customers and no brand.

They also hear a familiar pitch: an engineer has built something impressive and wants someone to sell it. The trouble is that the product was often built before anyone asked a buyer whether they wanted it. A strong seller can tell within one call whether that happened, and many say no for that reason alone.

Turn the pitch around. Show what you've learned from buyers, not only what you've built.

What to bring before you approach anyone

Write a short note about what you have. The point is to show a seller that the hardest question, whether anyone wants this, has at least a partial answer. Useful proof:

• Something people use. A working version with real users, even a few dozen. Usage data says more than a demo.
• Conversations with buyers. Notes from calls with the people who would pay, what they said hurts, and what they pay for now.
• A first sale or a pilot. One paying customer changes every conversation that follows.
• The commercial problem you can't solve. Be specific: you don't know how to reach procurement at hospitals, or you can't get past the free trial.
• What you won't do. Say plainly that customer meetings and sales calls will be theirs to lead, so it's clear what they'd own.

An example:

I've built a scheduling tool for home-care agencies. Fourteen agencies use the free version weekly, and two pay $200 a month. Every sale so far came from someone I know, and I've no idea how to reach agency owners beyond them. I need someone who has sold to care providers and wants to own sales and partnerships. I'm full-time on this and will keep building the product.

That tells a seller what exists, what's missing and what would be theirs.

Where to find a non-technical cofounder

Business people rarely gather at developer events. Look where they already work, and where your buyers are. We build Foundinity, so it comes first.

Foundinity

You state what you need in a cofounder, and answer an assessment about how you work: commitment, working style, ambition, personality, goals, values, alongside your skills and interests. If you need someone who sells, that's part of what you state. A multi-trait algorithm built on established psychological compatibility models ranks the people you see, and every match shows where the two of you align and where you differ. That matters here: engineers and sellers often work very differently, and it helps to know which differences you're taking on before the first call. When you match, a 10-day clock starts, and you can book the intro call in the app. Profiles are visible only to compatible members, and an "exploring" status lets someone with a sales job look without telling anyone. It's free to get started; Plus is $5 a week or $15 a month. More on how it works.

Your customers and the industry you sell to

The best business cofounder for a vertical product often already works in that industry. Think of the operations lead at a customer who keeps sending feature requests, the consultant who advises your buyers, or the account manager at a supplier your customers trust. These people know the buyers by name and can explain why a deal stalls.

Ask your current users and the people you've interviewed one extra question: who's the most commercially sharp person you know in this field? Then go to the trade shows and association meetings your buyers attend, not startup events. You'll meet fewer founders there and more people who understand the customer.

Former colleagues

In a 2026 Censuswide survey of 500 people for Starling Bank, 26% said they met their cofounder at a former workplace (startups.co.uk). As an engineer, you've probably worked with more commercial people than you realise: product managers, solutions engineers, customer success leads, account executives who brought you into calls. Think about who you'd trust in front of a customer, and who customers asked for by name.

People who sold at small startups

Selling at a ten-person company is a different job from selling at a large one. One reply in the 2025 Hacker News thread suggested looking for people who have done marketing at companies of fewer than 20 or 30 employees, where everyone covers several roles. Kazanjy draws the same line in *Founding Sales*: professional sellers at established companies are good at taking a known product to a known buyer in a repeatable way, which is a different skill from figuring out how to sell something new.

Look for the first or second sales hire at a startup that was acquired or shut down. They've built a pipeline from nothing and watched what worked.

Sales and go-to-market communities

Some communities are built for revenue people. RevGenius runs a Slack community for sales, marketing and revenue operations people, and it's free to join. Pavilion is a paid membership for go-to-market managers and executives, priced by seniority and location, with "Founder" as one of the seniority options and local chapter events. Join to take part, not to post a cofounder ad on day one: answer questions about selling to your kind of buyer, and see who gives the most useful answers.

Business schools and university programmes

MBA students and alumni are a common source of business cofounders, especially those who worked in sales, consulting or operations before their degree. Many business schools run entrepreneurship clubs, startup competitions and venture labs, and some open their events to engineers from outside the school. If you studied somewhere with a business school, the alumni network covers people with years of commercial experience.

Startup Weekend and hackathons

Startup Weekend is a three-day event where people pitch ideas, form teams and build a company together. You'll find people who want to do the business side, and you'll see them do it under a deadline: who talks to potential customers on Saturday morning, and who only polishes the pitch deck. Hackathons with a pitch or business track work the same way.

Full-time programmes

Some programmes form teams from individuals. Antler says solo founders and incomplete teams join its UK residency for up to 8 weeks, with the goal of forming a complementary founding team. Entrepreneur First doesn't require a cofounder or an idea to apply, though its FAQ says it takes only a small number of non-technical individuals, so expect most people around you to be technical too. Both expect you to commit full-time.

What to look for in a business cofounder

Titles tell you little. A sales director at a large company may never have sold without a brand, a marketing budget and leads arriving every morning. Look instead for:

• Pipeline they built themselves. They can describe how they found their own prospects, not only how they closed the ones they were handed.
• Knowledge of your buyer. They know how your customers buy, who signs off and what makes them say no.
• Curiosity about the product. They ask how it works and why you made the choices you did. A seller who never asks will make promises you can't keep.
• Comfort with numbers. They talk about conversion rates, sales cycles and how many conversations a deal takes, without being prompted.
• Clear writing. Most early selling happens by email. Read what they write.
• Follow-through. They send the notes after a call, unprompted, and do what they said by when they said.
• Tolerance for rejection. Ask how many prospects said no last quarter and how they felt about it. Good sellers can tell you.

Skills tell you who can do the job. The rest tells you who you can actually build with for years. A great seller who wants to raise money next month when you want to grow from revenue, or who works in bursts when you work steadily, is a hard partner to keep. Our list of questions to ask a potential cofounder covers hours, money, direction and conflict.

How do you judge sales skill when you've never sold?

You can't watch someone close a deal in an interview, and confident people interview well. Use evidence instead.

Ask them to walk you through real deals

Pick one deal they won and one they lost. Ask how they first found the customer, who was in the room, what the customer objected to, how long it took and what they would do differently. People who did the work give names, numbers and dates. People who were near the work describe what "the team" did.

Call people they sold to

Ask for a former manager and, if possible, a customer they sold to. Ask the customer what it was like to buy from them, and whether they'd take a call from them again. Ask the manager how they did against their target and how they got there. Altitude Accelerator, a startup support organisation in Ontario, warns that many would-be non-technical cofounders say they'll "handle the business side" without knowing what that involves, and suggests asking people who have worked with them whether they'd recommend them as a cofounder.

Sell together for two weeks

The most reliable test is real customer work. Agree a goal before you start, for example:

1. Agree on one type of buyer together. 2. They write the first outreach message and the list of 50 people to send it to. 3. They aim to book ten conversations in two weeks. 4. You sit in on as many calls as you can, and they write up what they heard. 5. At the end, you both review: how many replies, how many calls, what customers said and what should change in the product.

Watch whether they hit the number or tell you early why they won't, whether their notes change how you see the product, and whether customers ask to talk to them again. A short sprint with a review at the end was also the suggestion of a venture investor answering an early-2026 Hacker News question from a developer-tools founder looking for a go-to-market cofounder.

Check what they can do this week

Ask which ten people they could call tomorrow about your product. A seller with a real network in your industry answers quickly and specifically. If they need three months to "build relationships", factor that into your plans.

Mistakes technical founders make

• Looking for "a business person". It's too vague to answer. Say whether you need a seller, a marketer or someone from the industry, and why.
• Choosing for contacts alone. An address book runs out after the first twenty calls. You want someone who can keep finding customers once the friendly ones have bought.
• Recruiting a big-company closer. Someone who has always had a brand and a lead flow behind them may struggle to start from zero. Ask how they found their own prospects.
• Waiting until the product is finished. By then you've built a lot without a buyer's input. A seller who joins earlier shapes what gets built.
• Handing over every customer conversation. Keep joining some calls. If you stop hearing customers directly, you'll build for your cofounder's summary of them.
• Settling titles in the first conversation. Who's CEO and other terms come later, once you've worked together and both want to continue.
• Skipping the hours question. A strong seller who can only give evenings while keeping a job with a quota is a different partner from one who is full-time from next month. Ask in the first call.
• Treating idea people as sellers. Someone with many ideas and no customers has not shown they can sell. Ask for deals, not plans.

Write a first message that gets a reply

Keep it short and specific, and lead with what you've learned from buyers:

You spoke at the regional care-providers conference about why agencies drop scheduling software after the trial. I've built a tool that fourteen agencies use weekly, and I'm stuck on exactly that problem: they use it free and don't upgrade. Would you have 30 minutes to tell me what you'd look at first?

Ask for their view of a real problem, not for a cofounder. If the conversation goes well, the next step is a second call, then the two-week sprint.

Then run a longer trial

If the sprint goes well, agree a longer trial with a clear goal before either of you commits: a target number of paying customers, a pilot signed, or a price that buyers accept. Agree how long it runs and when you'll check in. Keep building where they can see it. They're judging you as well, and the best evidence you can give a seller is a product that improves every time they bring back what a customer said.

FAQ

What is a non-technical cofounder?

A cofounder whose main job isn't building the product. In most startups that means owning sales, marketing, customer relationships and the running of the company, while the technical cofounder owns the product and the technology.

How do I find a business cofounder as a technical founder?

Start with Foundinity, which ranks people by compatibility on multiple dimensions around who you are and how you work, and with people you've worked with in product, sales or customer roles. Then look in the industry you sell to, among early salespeople at small startups, and in sales and marketing communities. Bring proof that people use what you've built.

Do I need a sales cofounder or a first sales hire?

If nobody has worked out how to sell the product yet, a first hire usually struggles, because there's no process for them to follow. That work belongs to a founder: you or a cofounder. Once you have a way of selling that works and repeats, hiring salespeople makes more sense.

Should a technical founder learn to sell?

Yes, at least to the first few customers. You'll understand your buyers better and judge a sales cofounder far better if you've done some of the calls yourself. Kazanjy's *Founding Sales* is written for founders in exactly this position.

How do I evaluate a sales cofounder?

Ask them to walk you through a won deal and a lost one, call a former manager and a customer they sold to, and work together on two weeks of real outreach to your target buyers with a goal agreed in advance.

Can a marketer be a cofounder instead of a salesperson?

Yes, if your buyers come to you rather than waiting to be called. Products sold to consumers or small teams often grow through content, search, communities or paid channels, and a marketer who has grown something before fits that better than a salesperson.

Is a domain expert better than an experienced salesperson?

For a product built for one industry, often yes. Someone who has worked in that industry knows the buyers, the vocabulary and why deals stall. Check that they've sold or persuaded people before, though; knowing an industry and selling into it are different skills.

How do I find a non-technical cofounder with no network?

Build one around your users. Talk to the people who use your product and ask whom they'd recommend, go to your buyers' trade events, and take part in sales and marketing communities before you ask anyone to join you. Startup Weekend gives you a fast way to see business-minded people work.

What if a potential business cofounder wants to be CEO?

Discuss roles once you've worked together, not in the first call. Many technical founders are happy for the person closest to customers and investors to lead; others aren't. What matters is that you both agree before you commit.

Can a designer find a business cofounder the same way?

Yes. Everything in this guide applies to designers and other makers. Bring what you've built and what users told you, and look where your buyers and their sellers already are.
