Technical Co-Founder, Freelancer or Agency?
By CodexierPublished 7 min read
Every non-technical founder reaches the same fork: find someone to share the company with, hire a freelancer by the hour, or pay an agency for a fixed scope. The advice online is mostly written by people selling one of the three. This guide compares them on the things that decide the outcome of an early product in Sweden: cost, speed, continuity, control and what happens when the first version needs to change.
What a technical co-founder really costs
Equity looks free at the start because nobody is paying anything. It is the most expensive currency you have. A technical co-founder joining before the product exists usually expects a share close to yours, vested over several years, plus a say in every major decision. If the company works, that share is worth more than any agency invoice you will ever receive. If it does not, you have spent a year negotiating with a partner instead of talking to customers. The arrangement pays off when the person brings more than code: architecture judgement, hiring ability and the willingness to carry the product through three rewrites. It fails when the founder is really looking for a developer and offers equity because there is no cash.
Freelancers: speed and key-person risk
A good freelancer can start next week, works directly with you, and charges only for hours used. For a small, well-defined first version that is hard to beat. The risks are all about continuity. One person holds every decision in their head; if they take a full-time job, get sick or lose interest, you inherit a codebase nobody else understands. Quality varies enormously and is hard to judge without technical knowledge. And an hourly model has no natural end: scope grows, hours grow, and there is no fixed price to hold anyone to. Mitigate with a written scope, weekly demos, code in a repository you own, and documentation as a deliverable, not an afterthought.
- Ask for two references from projects that are still running a year later.
- Insist that the code lives in your company's GitHub or equivalent from day one, with your admin access.
- Agree a weekly hour cap and a demo every Friday; hours without a demo are a warning sign.
- Check F-tax status and get a written agreement on IP transfer; without it, the freelancer may own the code.
Agencies: process and price
An agency sells a team and a process: a scoping phase, a fixed quote, a project lead, designers and developers who have done this before, and someone to call when the original developer is on holiday. The price is higher than a freelancer's hourly rate would suggest, because you are buying continuity and reduced risk, not just hours. The trade-off is flexibility: a fixed scope means changes go through change requests, and an agency's process can feel slow when you want to pivot on a Tuesday. Agencies are strongest when the first version is well understood and the founder's time is better spent selling than managing developers.
| Factor | Technical co-founder | Freelancer | Agency |
|---|---|---|---|
| What you pay | Equity, vested | Hourly, open-ended | Fixed price per scope |
| Time to start | Months to find the right person | Days to weeks | Weeks, after scoping |
| Continuity | High, if the partnership holds | Low: one person | High: team and documentation |
| Control over scope | Shared decisions | Full, but scope drifts | Fixed, changes cost extra |
| Best for | Product is the company; deep tech | Small, clear first version | Defined MVP, founder busy selling |
| Worst case | Co-founder conflict, equity locked | Developer leaves, code unreadable | Overpaid for features nobody used |
Our own MVP development is the agency model with a published fixed price and delivery window, which is the honest way to make the comparison above.
Hybrid setups
In practice most Swedish startups we meet run a sequence rather than a choice. The first version is built by an agency or a trusted freelancer on a fixed scope, so the founder can show something to customers and investors within months. Once there is paying usage, the company hires its first developer or brings in a technical co-founder who inherits a working product, documentation and a codebase in the company's own repository. The agency stays on for maintenance or steps back. This works because the equity conversation happens when the company is worth something, and the person joining can judge what they are joining.
Fractional CTO plus agency
An experienced engineer a few hours a week reviews architecture and vendor work, without equity or a salary. Cheap insurance against building the wrong thing.
Agency build, in-house takeover
Write the takeover into the contract: documentation, a handover week, and a codebase with tests. Ask about it before signing, not after.
Freelancer with an agency safety net
A freelancer builds; an agency audits quarterly and can step in. Works when you have found a strong individual but want continuity cover.
Questions to decide
- Is the product itself the company, or is software one part of a service business? Only the first case justifies co-founder equity.
- Do you have cash for a first version? If yes, buying it keeps your cap table clean for the people who join later.
- Can you write down the first version in two pages? If yes, a fixed scope from an agency or freelancer is realistic. If no, start with a paid planning phase.
- Who will own and understand the code in a year? Whatever the answer, put it in the contract now.
- How long can the company survive if the builder disappears tomorrow? Your answer sets how much continuity you should pay for.
When you should not hire us or any agency: if you have found a genuine technical partner who believes in the product and you have the time to build together slowly, do that; it is the cheapest cash option and the best long-term one. And if the idea is still unvalidated, spend on customer conversations and a clickable prototype before spending on code. We say which case you are in on a 15-minute call, including when the answer is not us. How to pay for it is covered in funding an MVP in Sweden.

Frequently asked questions
How much equity should a technical co-founder get?
There is no market rate, only a negotiation about contribution, risk and timing. A person joining before the product exists and working unpaid for a year has a strong claim to a share close to equal. Whatever you agree, vest it over several years with a cliff, so an early exit does not leave the company with a passive shareholder.
Can a freelancer build a full SaaS product?
A strong one can build a first version. The question is what happens after: maintenance, security updates, scaling and the day they are unavailable. Plan for that from the start with your own repository, documentation and a second pair of eyes on the architecture.
Is an agency always more expensive?
Per hour, yes. Per finished, working product, often not, because a team with process makes fewer expensive mistakes and does not bill for learning on your project. Compare the total for a defined scope, not hourly rates.
Who owns the code when an agency builds it?
Whatever the contract says. In Sweden the default without an agreement can leave rights with the developer, so the contract must transfer full ownership on payment. Our agreements do; ask any supplier to show you the clause before you sign.
Unsure which route fits your idea and your budget?
Fifteen minutes with an engineer: you describe the product and the money available, we say whether a co-founder, a freelancer or a fixed-price build makes sense, and what to write into the contract either way.
