I · Where you start

Something needs building, and there's no senior engineer to build it.

Most people who call us start in one of four places. Find yours.

None of this should take an agency, a six-month hire or a leap of faith.

II · When it gets urgent

Then something makes it urgent.

  • Real users arrive, and the app slows down under them.
  • An investor asks who reviews the code.
  • A competitor ships the AI feature you've been planning.
  • The AI bill doubles, and nobody can say why.

Waiting makes the fix bigger: more users on shaky code, more months without a technical owner.

III · What you've tried

You've looked
at your options side by side.

Maybe an agency quoted a long timeline and an account manager. Maybe a freelancer stopped halfway, or AI tools got you a demo that won't scale. Here is how an agency and SoulToSoul compare on what matters to you.

Speed
A typical agency: Weeks of discovery, sprint ceremonies and handoffs before anything ships.
SoulToSoul: We ship fixed-scope builds in one to eight weeks.
Who you work with
A typical agency: Account managers and project managers in front of juniors you never meet.
SoulToSoul: The senior engineers who write your code, in your Slack from the first day.
Cost
A typical agency: Hourly billing for every layer, and a bill that grows with each change request.
SoulToSoul: We agree a fixed price before we start, and you pay for senior engineers only.
Quality
A typical agency: You trade speed against quality.
SoulToSoul: We hand the mechanical 90% to AI. Senior people own architecture, security and review.
AI
A typical agency: They ignore AI, or ship AI-generated code with little review.
SoulToSoul: We help you adopt AI where it pays off, with a person accountable for every decision.
After launch
A typical agency: A handover call, then a new statement of work for every fix.
SoulToSoul: Handover docs, a walkthrough with your team, and 30 days of support on builds.

In 20 minutes we'll tell you whether we're the right fit and what the work would take.

IV · Who you meet

You meet someone who has sat in your seat.

Your first call is with our founder, Serge. He was CTO of MortgageBloc, so he knows what it is to have more product to build than people to build it. Before that he was a tech lead at Ember, which Starling Bank acquired.

Teams often come to us with an MVP that AI tools built in a weekend and that now falls over with real users. We keep the speed and add the engineering it skipped.

Serge Radkevics, founder

Previously Tech Lead at Ember (acquired by Starling Bank) and at TribeIRL, CTO at MortgageBloc.

Our engineers let AI write the scaffolding, the tests and the boilerplate. A senior engineer decides what we build, checks that it is safe and puts their name on it. We can set your team up to work the same way. We help you navigate AI, human first.

V · Your first step

Your first step takes 20 minutes.

  1. 1

    You book 20 minutes

    You tell us what's holding the project back. You talk to the founder, not a salesperson, and if we're not the right fit we'll say so.

  2. 2

    You get a written scope and a fixed price

    After the call you get, in writing, what we would build, how long it takes and what it costs.

  3. 3

    You decide

    Nothing starts until you sign it off. If you'd rather build it with someone else, the plan is yours to take.

VI · The build

While it's built, you stay in charge.

Engineers draft with AI, and a senior engineer reviews every change before it ships. You talk to the people writing the code, in your Slack from the first day.

How the work is split between AI and people

AI accelerates

  • Scaffolding and boilerplate
  • Tests and documentation
  • Internal tools
  • CI/CD and monitoring

People decide

  • Business logic
  • Architecture decisions
  • Security and quality
  • Product priorities

VII · Launch

Then real users arrive.
This time it holds.

Six products we built are live today, from dispatch software for trucking companies to a marketplace of 15-second video pitches.

We also run our own early-stage products.

See the lab

VIII · What you keep

You come back with more than software.

  • A product that holds up with real users, and you know why.
  • Handover docs and a walkthrough, so your team can run it.
  • 30 days of support after the build.
  • Someone senior to call on, if you keep a fractional CTO.
  • A clear view of where AI saves your team time, and where it doesn't.
  • One fixed price, agreed before we started.

questions

For anything else, email hello@soultosoul.dev.

How can you be faster and cheaper than an agency without cutting corners?

Much of what an agency bills you for is coordination: account managers, handoffs, juniors learning on your project. We skip that layer. AI handles the repetitive coding, a senior engineer checks all of it, and your money goes to the people actually building.

Is AI-written code safe to put in production?

It can be, as long as someone senior owns it. Every change gets read by a person and goes out with tests and a security check. If you already have an AI-built MVP that feels shaky, that's the job the Build Sprint was made for.

Why are there no prices on the site?

Because projects differ too much for a price list to be honest. After a 20-minute call we write down the scope and a fixed price, so you see the full cost before anyone starts.

We're not technical. Can you help us work out where AI fits?

Yes. We look at how your team works, point out where AI would save time and where it wouldn't, and leave the decision with you. You're free to take that plan and build it with someone else.

Where are you based?

In Portugal, on Lisbon time, which lines up well with the UK and most of Europe.

Your next step
