Build-in-public experiment

You pitch. I build.

Bring the SaaS opportunity. I'll build the product. Then we find out, in public, whether it turns into a real business.

Don't just send the idea. Research the market. Talk to potential customers. Identify the competition. Work out how we reach the first users, and how the product makes money.

The experiment

Can a validated problem become software people pay for?

That is the whole question. I handle the technical side. The person whose submission is selected becomes the Growth Partner and handles business development and customer acquisition.

There is no guarantee a selected project succeeds. The point is to find out what happens when product building, market validation and customer acquisition run together — and to document the whole thing as it happens.

How it works

Six stages, in order

From a researched submission to a launched product with real numbers attached to it.

01

Submit

Tell me about the problem, the target customer, the proposed solution, the competitors, the business model, the market evidence, and the customer-acquisition strategy.

An idea alone is not enough.

02

We evaluate

Submissions are reviewed on the strength of the problem, evidence of demand, customer accessibility, monetisation potential, MVP feasibility, differentiation, and the proposed acquisition strategy.

03

Validate

Finalists may be asked to run further customer interviews, validate pricing, build a waitlist, or otherwise prove the opportunity is worth building.

04

I build

For the selected project I lead the engineering, build the MVP, deploy it, and handle the agreed technical infrastructure.

05

You grow

The selected submitter becomes the Growth Partner: validating the product, reaching customers, running growth experiments, acquiring users, and bringing feedback back into the product.

06

We launch and measure

We launch publicly, track the results, and document what happens — wins, failures, pivots, users, revenue and lessons.

Who does what

Two jobs, both real

Both sides are expected to contribute actively for as long as the project runs.

Builder

Me
  • Product architecture
  • UI/UX implementation
  • Software development
  • Database, API and infrastructure
  • Hosting and deployment
  • Technical maintenance
  • Bug fixes and technical improvements
  • Agreed technical operations

Growth Partner

You
  • Market research
  • Customer interviews
  • Customer validation
  • Positioning
  • Marketing
  • Customer acquisition
  • User feedback
  • Growth experiments

The 40% share is not payment for submitting an idea. It reflects the Growth Partner's active role in proving and growing the business.

The money

60% Builder, 40% Growth Partner

Published up front, so you know the commercial arrangement before you apply rather than after you are selected.

Net distributable profit

60%Builder

40%Growth Partner

The split applies to net distributable profit, not gross revenue. Agreed direct business expenses come out first.

Deducted first

Where applicable:

  • Hosting and infrastructure
  • Payment processing fees
  • Approved advertising spend
  • Necessary third-party software and services
  • Refunds, chargebacks and similar direct costs
  • Other mutually agreed operating expenses

What submitting does not give you

Submitting an idea does not automatically grant ownership, equity, intellectual property rights, or a permanent revenue share in the resulting product or company. Selected participants receive and agree to a project-specific collaboration agreement before development begins.

You do not need to complete or negotiate that agreement to apply. The application is the first stage; detailed terms are finalised only if your idea moves forward.

Strong submissions

What gets read twice

Six things the selected submission will almost certainly have.

A painful problem

The target customer clearly experiences the problem and has a reason to solve it.

Evidence of demand

You have spoken to potential customers, collected feedback, observed existing behaviour, or gathered other meaningful evidence.

A reachable customer

You can explain exactly where potential customers are and how we reach them.

A realistic MVP

The first version can be built and launched without trying to create an entire enterprise platform.

A clear business model

You can explain who pays, what they pay, and why the product is worth paying for.

A credible acquisition plan

You can explain how we get the first 10 users and, ideally, the first 3 paying customers.

Not this

What will not make it past the first read

Better you read it here than spend an evening writing a submission that was never going to fit.

  • A vague idea with no identified customer
  • “Uber for X” without strong evidence
  • A platform that would take years to build
  • An idea that depends entirely on running ads
  • A market where you have no realistic path to reaching customers
  • Ideas based only on assumptions, with no validation

The challenge

You are not handing me an idea and waiting

If your idea is selected, you become part of the build. You may be expected to:

I build the product. You help prove that people want it.

If it fails

We might build it and find that nobody wants it

That is not a failure of the experiment. It is a result. Depending on what we learn, the project may be:

  • Continued
  • Pivoted
  • Paused
  • Shut down

Whichever it turns out to be, it gets documented honestly — same as everything else.

Public build

Expect the journey to be filmed

By taking part, expect parts of the project to be shared publicly — videos, screenshots, product updates, milestones, lessons and business metrics. We agree reasonable boundaries around confidential information before development begins.

Before any code

What the written agreement settles

The terms above are the general model, published so you know what you are applying to. If an idea is selected, a project-specific collaboration agreement finalises the detail.

  1. 01The MVP scope
  2. 02Responsibilities of both parties
  3. 03Profit-sharing mechanics
  4. 04Eligible expenses
  5. 05Intellectual property and source-code rights
  6. 06Brand, domain and product ownership
  7. 07Customer and data responsibilities
  8. 08Minimum participation expectations
  9. 09What happens if either party stops contributing
  10. 10What happens if the project is paused, abandoned or terminated
  11. 11Any future equity or company arrangement

None of this has to be settled to apply. A written agreement must be accepted by both parties before production development begins.

Read the collaboration terms

The agreement is a template for selected projects. Project-specific terms are completed only after an idea is selected and both parties have agreed the details.

Your submission

What happens to the ideas I don't select

Most submissions will not be selected. This is what happens to them.

It isn't published

I don't post submissions, read them out in a video, or share them outside the review. If I ever want to reference one publicly, I ask first.

It isn't built without you

I don't take an unselected submission and build it myself. If an opportunity is worth building, it's worth building with the person who did the research.

It isn't kept forever

Submissions are held while the round is reviewed, then archived. Email me and I'll delete yours.

What that is not

Submitting does not create an NDA or any confidentiality agreement between us. Send only what you are free to share — no trade secrets, no private customer data, nothing belonging to an employer or a client.

Similar ideas arrive from different people, and I may already be working in the same space or be pitched it again later. So if a future project resembles something you sent, that resemblance on its own is not evidence that your submission was used. If you need enforceable protection for an idea, this programme is not the right route for it.

Questions

Before you write anything

Ready to pitch

Don't give me a SaaS idea. Give me a business opportunity you believe we can prove.

The application is the first stage — you are not expected to negotiate a full project agreement just to submit an idea. If your proposal is selected, we work through the project-specific details together and sign the agreement before development begins.

This page is a plain-language overview of the programme. The signed project-specific collaboration agreement controls the legal relationship between the parties.
