Agency vs freelancer vs AI tools for an MVP

UK agency

Funded teams who want a project managed for them and have £30,000 or more to spend.

Freelancer

Founders with a clear spec who can manage the work, or who have someone technical to check it.

AI tools

Anyone testing an idea for the first time. Start here before you pay a person.

Many founders asking this have already decided they need someone. Some of them don't yet. If you haven't shown the idea to ten people who might pay for it, an AI builder and a weekend will teach you more than a £30,000 invoice. The rest of this page is for when you're past that point.

Agency vs freelancer vs AI tools at a glance

When to choose each option

Choose AI tools when

• You want to find out if anyone cares before spending real money.
• You need something to put in front of ten users, an investor or a co-founder next week.
• The product is mostly forms, lists and a dashboard, and nobody pays through it yet.

Use Lovable or Bolt, keep it rough, and talk to users. If the idea dies, you've lost a few weeks and a monthly subscription. That is a good outcome.

Choose a freelancer when

• You have a written spec, or a working prototype that shows what you mean.
• You, or someone you trust, can review the work and say no.
• The budget is under agency level but you need real code that someone can maintain.

YunoJuno's rate data puts the UK average for software engineering contractors at £533 a day in 2025, so the job board medians are not outliers. A senior freelancer is often the best value per pound on this page. The catch is that you become the project manager, and if you hire a developer you probably need a designer too, which means two diaries and two invoices.

Choose an agency when

• You have funding and would rather pay for process than run it yourself.
• The product needs several specialists at once: native mobile, data, compliance.
• You need someone who will still be there in two years with a team behind them.

Agencies make sense when the project is bigger than one person. For a first MVP that is often not the case yet.

Hidden costs and common traps

Agencies

• Discovery before the quote. Many agencies charge for a discovery phase before they will commit to a build price. One UK agency lists discovery from £3,000. That can be good value, but it is money spent before anything is built.
• Senior pitch, junior delivery. Ask who will actually design and build your product, and meet them.
• Change requests. Fixed-price scopes are tight. Anything new becomes a priced change.

Freelancers

• Copyright. In the UK, a contractor usually owns the copyright in what they write unless your contract assigns it to you. Get the assignment in writing before you pay.
• The design gap. A developer will build what you describe. If you can't describe it well, you get a working app that is hard to use.
• Hourly drift. A day rate with no cap on days is not a budget. Ask for a fixed price per milestone.

AI tools

• The last 20 percent. Getting to a demo is quick. Getting to something you'd let strangers put card details into is not. Auth, data permissions, error handling and payments are where AI-built apps usually fall down.
• Credit burn. Both Lovable and Bolt meter usage, in credits and tokens. A prompt spent chasing a bug uses up your allowance just like one spent building, and bugs can take a lot of prompts.
• Your time. The subscription is cheap. The evenings are not free.

If you already have an AI-built app and want to know how far off it is, I've written about fixing a vibe-coded app.

Where BlackFig fits

I'm a fourth option that sits between the freelancer and the agency. I'm a senior product designer who also writes the code, so you get design and build from one person, with one price and no handoff between a designer and a developer.

The MVP Build starts at £12,000 and typically goes live in 4 to 6 weeks, depending on scope. If you're not sure what to build yet, the Validation Sprint starts at £3,500 and takes 1 to 2 weeks. The code, hosting and accounts are in your name from day one. I use AI tools to move faster on the repetitive parts, and I review everything they write.

That is not cheaper than a weekend in Lovable, and it shouldn't be. It is cheaper than most agency quotes because there is no team overhead. The trade-off is capacity: I take a few clients at a time, and I won't suit a project that needs ten people from day one.

You can see how I work on a real product in the FindPopups case study, a two-sided marketplace I designed and built. For a breakdown of what MVPs cost across all these options, read how much an MVP costs in the UK.
