First, a confession: I'm an agency founder. So in this post I'll take extra care to stay neutral, because not every startup needs an agency. Sometimes the right answer is “nobody yet — test it yourself first”.
Let's go through the options one by one.
1. A technical co-founder
Someone who owns the company together with you and is responsible for the technical side of the product.
- Strength: long-term commitment. They take equity instead of a salary, think about the product with you and don't run when times get hard.
- Risk: the right person is hard to find, splitting equity is complicated, and a mismatch between partners can paralyse the company.
- Who it suits: startups where the product itself is the technology — where your competitive edge lies in the technology.
In “Let's build an IT startup, bro” I described how the “we'll give the developer a cut” approach ends: a co-founder isn't an employee but a partner, and you have to do as much work as they do.
2. A hired developer
- Strength: full focus, the knowledge stays inside the company, the product moves forward every day.
- Risk: one person doesn't know everything. Backend, mobile, interface, servers and testing are separate skills. Add hiring, management and a salary every month.
- Who it suits: when the product already works, has users and needs continuous development.
3. A freelancer
- Strength: flexible and cost-effective for small jobs. A specific task, a specific result.
- Risk: dependence on one person, availability (they work on other projects at the same time), uneven quality.
- Who it suits: small jobs with a clear scope, and prototypes.
4. An agency
- Strength: a ready team — analyst, designer, developers, testing. A process, and responsibility for dates and results. When someone falls ill, the work doesn't stop.
- Risk: it costs more, you're not their only client, and the product knowledge may stay inside their team — that is, outside your company.
- Who it suits: a first version with a clear scope, when speed matters and there's no in-house team.
5. Yourself
Yes, yourself. No-code tools, a landing page, a form, a Telegram bot — these are often enough to test an idea. I wrote about this in detail in “MVP: how to build a first version that fits into 6 weeks”.
- Strength: the cheapest and fastest test.
- Risk: limitations. When the product grows, you'll have to move to another solution.
Which one, and when?
- The idea hasn't been tested yet → yourself, or a simple prototype with a freelancer.
- The assumption is confirmed and you need a first real version → an agency or a strong freelancer, with an independent technical adviser alongside.
- The product works and is growing → an in-house team, a tech lead, and when the time comes, a CTO at co-founder level.
Whoever you choose: 5 rules
- Keep the accounts in your name. The domain, hosting, App Store and Google Play accounts, the code repository — all in the company's name.
- Pay in stages. A working result at the end of each stage, then the payment.
- Written scope and acceptance criteria. Write down in advance what “done” means.
- Documentation. Another team should be able to pick up the work tomorrow.
- Start with a small trial task. A week or two of work before a big contract will show how you work together.
The bottom line
The right choice depends not on who is better but on what stage you're at. Hiring a big team for an untested idea is just as risky as leaving a working product to one person's goodwill.
If you're not sure which road suits you, let's look at your situation together in a mentorship session — even if the answer isn't an agency.
