Technical Cofounder vs Development Agency: What Each Costs in Equity, Cash and Time

What You Are Actually Choosing

A technical cofounder and a development agency are not two prices for the same thing.

• A technical cofounder is a co-owner. They build the first version, then own the technology for years: architecture, hiring engineers, security and the technical half of fundraising. You pay in equity now, and in salary once the company can afford it.
• A development agency or studio is a supplier. It builds a defined product for a fee and hands it over. You keep your equity. You also keep the job of deciding what happens next.

So the useful question is not "which is cheaper?" It is "what problem do I have right now?" If the problem is "nobody can build version one", either can solve it. If the problem is "this company needs a technical leader for the next decade", only a cofounder or a senior hire can.

There is a third need that is neither: part-time technical judgement, such as checking a vendor's work or speaking to investors about architecture. That is covered in fractional CTO vs development partner. And if you want the practical steps of getting an MVP built without a technical partner, see MVP development for non-technical founders. This page is about the bigger decision: give away part of the company, or pay for the build.

What a Technical Cofounder Costs in Equity

There is no legal standard for cofounder equity. There are two useful data points, and they pull in slightly different directions.

• Y Combinator recommends equal splits. In a 2015 YC essay, partner Michael Seibel wrote that "equal or close to equal equity splits among founding teams should become standard". His reasoning: it takes 7 to 10 years to build a company of great value, so who did more in the first few months matters little over that span. He also warns that a cofounder given a small stake, such as 10% or 1%, can look to investors like a less capable or less impactful cofounder.
• Many teams still split unequally. Thomas Hellmann and Noam Wasserman studied 1,476 founders in 511 ventures (NBER working paper, 2011) and found that roughly one third of founder teams split equity equally. Teams that split equally often agreed very quickly, in less than a day, and equal splitting was associated with lower pre-money valuations in first financing rounds.

Read together: a technical cofounder who will build and run the technology should expect a large stake, near equal in a two-person team. But the split deserves a real conversation about who brings what, not a 50/50 agreed in an afternoon. The research found an association with lower valuations, not proof that equal splits cause them.

If you were planning to offer something like 10%, Seibel's warning applies. Investors may read that person as a junior cofounder, and the person may too. At that level you are probably describing an early employee or a contractor, which is a different and cheaper relationship.

What the stake is worth in dollars

Equity feels free because no money leaves your account. One way to put a price on it is Y Combinator's own standard deal: $125,000 for 7% of the company on a post-money SAFE.

• Implied post-money valuation: $125,000 ÷ 0.07 = $1,785,714.
• 1% of the company at that price: $1,785,714 ÷ 100 = about $17,857.

Rounded to the nearest dollar. YC also invests a further $375,000 on an uncapped SAFE, which is left out here because it has no fixed price. See Sources.

Three caveats keep this honest. It is paper value: only companies YC accepts get that price, and most early companies never reach it. A cofounder gives years of work, not one build, so a 40% stake is not "overpaying for an MVP". And if the company fails, the equity is worth nothing to anyone.

The point is narrower: do not hand over a cofounder-sized stake when what you need is a one-off build. Equity is the most expensive way to pay for something you could buy for cash.

Equity is also not the only cost. YC's own FAQ says the first use of its investment should usually be the founders paying themselves a salary so they can work full time. Once you raise, your technical cofounder draws a salary too. The real cofounder deal is equity plus, later, cash.

Vesting: The Protection Most Founders Skip

Vesting means a founder earns their shares over time. If they leave early, the company keeps the part they have not yet earned. It is what stops a cofounder from walking away after three months with a third of your company.

The standard terms are well documented:

• Stripe Atlas: most founders choose four-year vesting with a one-year cliff, starting on the date of incorporation. Shares vest monthly at 1/48 of the grant, and 25% vests on the cliff date. Atlas says a one-year cliff is "typically the industry standard and preferred by investors".
• Clerky: customary founder terms are monthly vesting over 4 years with a 1-year cliff, plus 100% double-trigger acceleration. That means unvested shares vest early only if both things happen: the company is acquired, and the founder is then let go without cause.
• YC: Seibel's essay describes the same four-year, one-year-cliff setup and explains its purpose: a cofounder who turns out to be a poor fit in year one can leave without taking a large share of the company.

Worked example: a cofounder with 40%

Say your technical cofounder is granted 40% of the company on the standard schedule. Here is what they keep if they leave at different points:

The last row is the one to avoid. Without vesting, a cofounder who leaves after three months keeps 40% of the company, and you pay someone else to finish the product with the 60% that is left.

Practical points

• Vest yourself too. The standard applies to every founder. A non-technical founder who asks only the technical cofounder to vest is asking for a fight.
• Credit work already done. Stripe Atlas lets you set a vesting start date up to six months before incorporation. Clerky gives an example of issuing 25% of a founder's shares fully vested and vesting the other 75% over 36 months, for founders who worked full time before incorporating.
• In the US, ask about the 83(b) election. The IRS says an 83(b) election "must be filed no later than 30 days after the date the property was transferred". Form 15620 is one way to file; a written statement is the other. Talk to an accountant before you receive the shares, not after. Outside the US the rules differ, so ask a local lawyer.
• Assign the IP to the company. Code a cofounder writes, especially before the company exists, should be assigned to the company in writing. Expect investors to ask who owns it.

What an Agency Costs in Cash

Market prices for an MVP vary a lot by who builds it. Our MVP development cost guide puts general ranges at $8,000 to $25,000 with freelancers, $15,000 to $40,000 with offshore teams and $50,000 to $150,000 or more with agencies.

minidev.pro's prices are published in our price list. The base MVP is $5,000 fixed, delivered in 30 days or less, and covers sign-up, one core workflow, a database, Stripe checkout or a waitlist, a basic admin view, a landing page, deployment and 30 days of post-launch fixes. Add-ons have fixed prices.

Worked example: a small B2B subscription product

Prices from our published price list. At YC's deal price, $7,500 is $7,500 ÷ $1,785,714 = 0.42% of a company.

If we miss the agreed delivery date, and the delay was not caused by scope changes you asked for, you get a full refund of what you paid plus $2,000. That is in our terms.

The cost after launch

An agency's cost does not stop at launch if the product keeps changing. Your options after the 30 days of included fixes:

• Leave it alone while you sell and learn. Many MVPs need few changes in the first months.
• Hire your own developer, who picks up the code and the handover.
• Use a retainer. Our Growth Partner retainer is from $5,000 a month for 60 hours of senior development, month to month with 7 days notice. A full year is 12 × $5,000 = $60,000.

That $60,000 is real money. The honest comparison is this: cash you can stop paying in any month, against equity you cannot take back once it has vested.

Time: Finding a Cofounder vs Shipping

We could not find reliable public data on how long it takes to find a technical cofounder, so we will not quote a number. What we can say is that the search has no fixed end date. You have to meet someone, find out whether you work well together, agree the split and vesting, and then they still have to build the product. Any step can fail and send you back to the start.

An agency is a purchase with a date. At minidev.pro the timeline is in the contract: 30 days or less, with the refund-plus-$2,000 guarantee behind it.

The gap matters because months spent searching are months not spent learning from users. But speed is not everything. The right cofounder found later may be worth far more than a product shipped sooner. The better question is what you can learn while you search, which is where the build-first approach comes in.

Control and IP

Control cuts both ways. With an agency, you hold all the decisions, which also means you hold all the responsibility for technical choices you may not be able to judge. With a cofounder, you give up some control and get a partner who owns those choices.

What Investors Expect

If you plan to raise venture money, this section matters most, and the evidence leans toward the cofounder.

• Y Combinator's FAQ, answering a non-technical founder: "It's important for the founding team to have the skills to build their product themselves, rather than outsourcing it to someone else. For most businesses, that usually means you need a technical co-founder."
• YC on solo founders: "We regularly accept solo founders", but its advice remains that "one-person startups are tough and you're more likely to succeed with a co-founder."
• Paul Graham (YC cofounder, 2006) listed "hiring bad programmers" as a startup killer, because non-technical founders "can't tell which are the good programmers", and added that "no one really good wants a job implementing the vision of a business guy."

The fair reading: if your plan is accelerators and seed venture capital, with software as the product, an agency-built MVP on its own will not satisfy investors. They will ask who owns the technology for the next five years, and "our agency" is a weak answer.

Two things soften this. First, not every company needs venture money. A business funded by its own revenue, a B2B tool for a niche market, or a service business adding software answers to customers, not to an accelerator's criteria. Second, an MVP with paying users changes the conversation. It does not replace a technical founder for YC, but it is evidence of demand, and it is the strongest thing you can show a technical cofounder you want to recruit.

Decision Table

When a Technical Cofounder Is the Better Choice

We build MVPs for a living, so here is where we would tell you not to hire us, or at least not only us:

• Technology is the moat. If your advantage is a new algorithm, a model you train, a hardware product, developer tools or security infrastructure, the hard part cannot be scoped into a fixed 30-day build. You need someone who owns it full time.
• You are raising venture money on a technical thesis. Investors will judge the team that builds the technology. A technical cofounder is part of the product they are buying.
• The product needs heavy engineering from day one, for years. If the roadmap is mostly hard technical work rather than workflows and screens, paying an agency every month for years costs more than it saves, and you never build the in-house knowledge.
• You have found the right person. If you have worked with a strong engineer before and they want to commit for years, that is rare. Do not let an agency quote talk you out of it.

Even then, an agency can help at the edges: building a non-core part, such as an admin tool or a marketing site, or adding capacity for a deadline. It does not replace the person.

Build First, Recruit With Traction

For many non-technical founders the choice is not either-or. It is a sequence: pay cash for a focused MVP, get real users, then recruit a technical cofounder with evidence.

Why this order works:

• It removes guesswork for both of you. A strong engineer is weighing your company against a job offer. Users, retention and revenue are more persuasive than a deck.
• It shows whether you need a full-time technical partner at all. Some products turn out to be mostly sales and operations with modest software. Others clearly need deep engineering. You find out with real data.
• It protects your equity while risk is highest. The earliest stake is the most expensive one you will give away, because nothing is proven yet.

How to do it

1. Do the customer work first. Talk to the people you want to sell to and name a first user. Our non-technical founders guide lists what to bring before you pay anyone.
2. Build only the core, in the company's name. Keep the code repository, hosting, domain and Stripe account in the company's name from day one, so a future cofounder inherits clean ownership.
3. Get real usage. Run the product with real users for a few months. Write down what they use, what they ignore and what they pay for.
4. Recruit with evidence. Show candidates the repository, the handover notes and the numbers. Let them read the code before they commit.
5. Work together before you split equity. A paid trial project on the real codebase tells you more than ten coffees.
6. Agree equity with standard vesting. There is no reliable public data on how much a cofounder who joins after launch receives. It is negotiated, and traction gives you more to negotiate with. Use the four-year, one-year-cliff schedule whatever the number.

You can see what a fixed-scope build produces in our case studies, and how the price adds up in the MVP cost calculator.

When We Are Not the Right Choice

minidev.pro is a supplier, not a cofounder. Our MVP development is a fixed cash price for a fixed scope, delivered in 30 days or less. That makes us the wrong choice if:

• You are looking for a long-term technical owner who shares the risk. We hand over the product and the code. We do not join your cap table or run your technology for the next decade.
• Your product is research. If nobody knows yet whether the core technology can be built, you need a technical founder or research team with room for dead ends, not a fixed scope.
• You have not spoken to customers yet. Do that first. A landing page, a spreadsheet or a no-code tool may answer the question for less.
• You need an independent technical voice, for example to judge vendors, including us, or to sit in investor meetings. Hire a fractional CTO or technical advisor for that. See fractional CTO vs development partner.

We fit when the risk is demand rather than technology, the first version can be scoped, and you would rather spend a few thousand dollars than a large share of your company to find out whether people want it.

Frequently Asked Questions

Do I need a technical cofounder to start a tech startup?

Not to build and test a first product. A development agency, a freelancer or a no-code tool can do that for cash. You do need one when technology is the moat, when the product needs years of hard engineering, or when you plan to apply to accelerators such as Y Combinator, which says that for most businesses the founding team should be able to build the product itself.

How much equity should a technical cofounder get?

There is no legal standard. Y Combinator recommends equal or close to equal splits, and in a study of 1,476 founders in 511 ventures, Hellmann and Wasserman found roughly one third of teams split equally. For a two-person team where the technical cofounder builds and runs the technology, plan for a large, near-equal stake on a four-year vest with a one-year cliff, not 5 or 10%.

What vesting schedule should cofounders have?

The common default is four years with a one-year cliff: nothing vests in the first year, 25% vests at the one-year mark, and the rest vests monthly at 1/48 of the grant. Stripe Atlas describes the one-year cliff as the industry standard and preferred by investors. Put every founder on it, including yourself. In the US, ask an accountant about an 83(b) election, which must be filed within 30 days of receiving the shares.

Should I give a development agency equity instead of cash?

Usually not. An agency builds a defined product and moves on, so equity buys you no long-term commitment. Valued at Y Combinator's standard deal price of $125,000 for 7%, a $5,000 to $15,000 build is worth 0.28% to 0.84% of the company. Pay cash for a build and keep equity for people who will work on the company for years.

Will investors fund a startup whose MVP was built by an agency?

Some will and some will not. Accelerators such as Y Combinator prefer founding teams that can build the product themselves. An agency-built MVP with paying users shows demand, but investors will still ask who owns the technology long term. If you plan to raise venture money, have an answer: a technical cofounder you are recruiting, or a clear plan to hire one.

Can I bring in a technical cofounder after an agency builds the MVP?

Yes, and it is often easier. With working software, users and the code in your company's name, a candidate can judge the opportunity on evidence rather than a pitch. Expect them to want to change or rewrite parts of the code. That is normal: the MVP's job was to prove demand, not to last forever.
