If you're not going to build your startup's product yourself, you have five realistic options: hire your first in-house engineers, use a dev shop or agency, assemble contractors from a talent marketplace, bring on a fractional CTO, or join a venture studio. A sixth, a founding engineering team like Founding Ten, sits between hiring and outsourcing. The right choice comes down to three questions: who actually writes the code and how senior are they, what you give up to get it (equity, or just a fee), and whether you want a permanent hire or a fixed engagement.
The options, side by side
| Option | Who builds it | What you give up | Who owns the code | Commitment | Best when |
|---|---|---|---|---|---|
| First in-house hire | The engineer you recruit (months to find the right one) | Salary + meaningful equity | You | Permanent | You have traction and need a durable long-term team |
| Dev shop / agency | Assigned developers; seniority and location vary. Verify who actually does the work | Project fees; you manage the vendor | Usually you (check the contract) | Per project | The build is well-specified and you can manage vendors |
| Talent marketplace | Vetted contractors you assemble yourself | Hourly rates; you still vet, manage, and integrate | You | Flexible | You have the technical leadership to direct contractors |
| Fractional CTO | No one; they advise, architect, and hire | A monthly retainer | You | Part-time | You need senior leadership, not hands on the keyboard |
| Venture studio | The studio's shared team | 20-35% equity (often a co-founder seat) | The studio or co-owned | Deep, equity-based | You're pre-idea and will trade equity for a co-founder + capital |
| Founding engineering team | A senior team that builds it for you | A monthly retainer, no equity | 100% you | Monthly retainer | You want senior development without hiring, and want to keep your equity and code |
Generalizations, individual vendors vary. Always confirm seniority and IP ownership in the contract.
When each one is the right call
Hire in-house
Once you have product-market fit and durable funding, a permanent team usually wins on cost and continuity. The catch early on is time and risk: a great senior first hire can take months to find, costs real equity, and is hard to reverse if it's the wrong fit.
Dev shop, agency, or marketplace
Good when the work is well-defined and you can carry the management overhead. The risk founders underestimate is ownership: the people who pitched you aren't always the people who build, and code written to ship a demo often gets rebuilt later. Seniority and a clear IP clause are what separate a good engagement from an expensive rewrite.
Fractional CTO
The right fit when your gap is senior leadership (architecture, hiring, technical strategy) rather than building. A fractional CTO generally won't write most of your code, so pair them with people who will.
Venture studio
A strong option if you're very early and want a co-founder, capital, and a team in one, and you're comfortable trading 20-35% of the company for it. The trade is permanent: that equity and influence don't come back.
Where a founding engineering team fits
A founding engineering team builds your product end to end for you, the way your first engineering hires would, but on a monthly retainer instead of payroll. Think of it as a senior developer or team on salary, without the recruiting, the management, the payroll, or the equity. You keep 100% of your equity (unlike a venture studio) and own all of the code and IP outright. It's the right fit when you need senior development now, but aren't ready (or don't want) to commit to permanent headcount or give up part of your company.
That's the model we run at Founding Ten. It's how we built ClinSight, Oriva Health, and Custosa: real products in regulated health and AI, shipped end to end. If that's the shape of help you need, tell us what you're building.
Common questions
Should I hire a founding engineer or use a dev agency?
If you can find and afford a great senior engineer who wants to commit long-term, an in-house founding engineer is ideal. If you can't yet, the real question is whether you'd rather manage a vendor (an agency) or have a senior team build it for you on a retainer. Agencies are often cheaper per hour but you carry the management and integration; a founding engineering team trades a higher monthly fee for senior delivery, code you keep, and your equity intact.
Do I need a technical co-founder?
Not necessarily. A technical co-founder gives you equity-aligned, permanent technical leadership, but they're hard to find and cost meaningful equity. If your blocker is getting the product built rather than long-term technical leadership, a strong first hire or a founding engineering team can get you to traction without giving up a co-founder's share.
What's the difference between a fractional CTO and a founding engineer?
A fractional CTO is a part-time senior leader who advises, architects, and hires. They generally don't write most of the code. A founding engineer (or team) is the person actually building it. Early on many founders need the building more than the advising; some need both.
How do I build my product without giving up equity?
Pay for the build instead of trading equity for it. In-house hires cost equity plus salary, and venture studios take 20-35%. Agencies, marketplaces, and a founding engineering team are paid engagements, so you keep your cap table intact and, with the right contract, own all the code.
Why do outsourced MVPs often get rebuilt?
Usually three causes: junior engineers behind a senior pitch, no ownership of architecture decisions, and code written to ship a demo rather than to be built on. The fix is seniority and ownership: whoever builds your MVP should be good enough that you'd have hired them, and accountable for the codebase you'll grow.
When should I just hire in-house instead?
Once you have product-market fit and durable funding, a permanent team usually wins on cost and continuity. Before that, when speed, seniority, and flexibility matter more than permanence, an engagement-based team is often the better risk.
