Custom Software Development

Custom software, built from scratch and reviewed by people.

Senior engineers lead the build and supervised AI coding agents do the volume. Every change goes through review, and a person merges it. You get the speed of AI without code nobody has read.

20 minutes. Walk away with your first quick win.

Software development for non-technical founders and busy teams.

✓Founders with a product to build and no engineering team yet.
✓Software companies of 5 to 500 people starting a new product while their engineers stay on the core one.
✓Teams that want AI to speed up the build, with a senior engineer accountable for what ships.

Building a software product from scratch, step by step.

01

Scope with a senior engineer

We agree what to build first, the architecture and the data model, and what to leave for later.

02

Framed issues

Each piece of work becomes a GitHub issue with acceptance criteria, so everyone agrees what done means before code is written.

03

Agents write draft pull requests

Supervised AI coding agents write the code in draft pull requests, with tests, on your repo.

04

Review and adversarial audit

Each pull request is reviewed against its criteria, and a separate agent tries to break it before a person looks.

05

A person merges

Nothing reaches your main branch until a person has read it and merged it.

AI-assisted software development, led by senior engineers.

Agents are fast at writing code. They are not accountable for it. On every build, a senior engineer owns the calls agents shouldn't make on their own.

✓Architecture, data model and choice of services.
✓Security, authentication, payments and anything that handles customer data.
✓What gets merged, and when a change needs a rethink rather than a fix.
✓Tests and continuous integration from the first week, so the product can keep changing safely.

How this compares with an agency, freelancers or a hire.

01

Agency or studio

Usually a fixed scope and a handoff at the end. We work month to month, and the same people stay as the product changes.

02

Freelancers

Flexible, but you manage the work and judge the code yourself. We bring the senior judgment and the review process.

03

Full-time hire

The right move once the product is proven. We help you hire and hand over when you are ready.

04

Technical co-founder

Hard to find and costs equity. A fractional CTO gives you senior technical leadership while you look, or instead.

05

No-code and AI app builders

Fast for a first version. When it needs real users, real data and security, we take it to production.

Month to month, scoped after a free audit.

Builds are priced as a monthly engagement, scoped with you after the free AI audit. There is no fixed project quote and no long contract, and you can change or stop the work month to month.

Already have a prototype?

01

Need a prototype first

If you need an AI MVP to test the idea before building the real product, start there.

02

Have an AI-built app

Built something with Lovable, Bolt or Cursor that now needs to hold up? We make it production-ready.

03

Need a technical lead

Architecture, hiring and investor due diligence from a fractional CTO who also builds.

Before you ask.

How much does it cost to build a software product from scratch?

It depends on scope. We price builds as a monthly engagement, scoped with you after the free AI audit, so you are never locked into a fixed quote for a product that will change.

Do I need a CTO or a technical co-founder to work with you?

No. A senior engineer leads the build and makes the technical calls. When you are ready to hire, we help you find and hand over to your own team.

What does AI write, and who checks it?

AI coding agents write most of the code in draft pull requests. Each one is reviewed against agreed criteria and audited by a separate agent, and a person merges it.

Is AI-written code secure and maintainable?

It can be, with the right checks. We keep security-sensitive work with senior engineers, require tests and review on every change, and never merge code nobody has read.

Can you work with my existing developers?

Yes. We can lead a new product next to your team, or set up the same process inside it so your developers ship with supervised agents too.

What if I already built a prototype with Lovable, Bolt or Cursor?

Then we start from what you have. We review it, fix what blocks launch and keep building, rather than starting over.
