Turn your idea intoa business that runs itself.

Tell Macromuffin what you want to build. It builds it, runs it, and improves it (the website, the outreach, the day-to-day) without you hiring anyone. Keep 100% of what you make, and own your stack and data.

We’re opening to a small first group. One email when it’s your turn, and nothing else.

When people ask these assistants for a recommendation, your business can be the answer.

How it works

From an idea in your head to a business that runs.

Tell it your idea

Describe it in plain words. No idea yet? It’ll help you find one worth building.

It builds the business

Site, product, first outreach, all set up for you. Anything public waits for your yes.

It runs the day-to-day

The busywork a team would handle, done while you sleep. A briefing every morning.

It improves on its own

It watches your numbers and acts: tests new versions, ships the winner.

What it does

A full team’s output. For the price of a tool.

Five jobs you’d otherwise hire for, running from day one.

You stay in charge

It works on its own. Nothing risky ships without you.

Anything public or money-related waits for your yes.

Routine work it just does, so you’re never the bottleneck.

Flip any decision from plain English to the full technical trail.

While you sleep, your business keeps working.

You wake up to progress, not a to-do list. Approve what matters; it handles the rest.

Be first in when Macromuffin opens.

We're opening to a small group first. Leave your email and we'll tell you the moment it's your turn. Nothing else from us in the meantime.

Questions founders ask

Good to know.

Yes. Tell it what you’re interested in or good at, and it’ll work through ideas with you until you’ve got one worth building. Then it builds it.

Anything public, or that spends money, waits for your approval. Routine work like drafting, analysis and testing, it does on its own so you don’t have to.

No. The default is a plain conversation. The full technical detail is there if you want it, and out of your way if you don’t.

Never. You keep 100% of what you make. No revenue share, ever.

You own your data and your stack, and you can bring your own models, so you’re never locked to one vendor.

We’re building automated Companies House and Making Tax Digital support for UK founders. It’s early and rolling out. If that’s important to you, tell us and we’ll keep you posted.

You bring the idea. It builds the business.
