You've got the audience. There's a product hiding in it.
I build the software your audience already needs — and we own it together. You bring the reach. I build and run it. Nothing upfront. 50/50.
Built with creators like Alex Welsh (Locksmithing Secrets) — now my co-founder on KeySolved.
I've already done this — here's how it worked.
Alex Welsh teaches locksmithing to a 28k-strong audience. His students kept asking the same thing on every job: which key, which tool, for which car? The answer was scattered across forums, PDFs and WhatsApp groups.
So we built KeySolved — the reference app that answers it in seconds. I built it and run it. Alex brings his audience and is my co-founder. We split it 50/50, fully transparent.
That's the whole model. Your audience has its own version of that question. I find it, build it, and we own it together.

Simple, and weighted in your favour.
You bring
an engaged audience and the commitment to market the product to them — the same way I commit to building it.
I bring
the entire product: build, infrastructure, data, support, and the day-to-day running of it.
We split
revenue 50/50 after costs. Both of us see the Stripe dashboard. No equity games, no hidden fees.
You pay
nothing upfront. Your reach is the investment.
We start trading through existing accounts, sign a simple heads of terms, and formalise properly once it's making real money — not before.
Do the maths on your own audience.
A small slice of an engaged audience is a real monthly income. Drop in your numbers and see your half — after costs.

Illustrative. Your half of revenue after an assumed ~15% for payment processing and running costs, split 50/50. Conversion is the share of your audience who subscribe — for context, KeySolved had ~0.3% subscribed on day one and grows from there. Real numbers depend on your audience and product.
A product person, not an agency.
18 years building products — including leading product design at Habito, where the software I worked on processed £3B+ in mortgages* — and 100+ products shipped through Hello Crossman. I build production-grade software in ~30 days, not 30 weeks. You're not getting a freelancer or an offshore team; you're getting a co-founder who can actually ship.

This works when:
You've got an engaged audience (a list, a channel, a community), not just a follower count.
Your audience hits the same painful task repeatedly — a lookup, a calculation, a piece of admin they all complain about.
You'll actually market it. This only works if you drive it.
If that's you, there's almost certainly a product hiding in your audience. The call is where we find it.
The questions everyone asks.
Let's find the product in your audience.
One 15-minute call. I'll come having looked at your audience, with a view on what the product could be. No pitch deck, no obligation.
