Built by day eight. You can click it.
Six figures and six months is a lot to commit to off the back of a deck. A second opinion costs a fraction of the quote and takes ten days. A good agency will welcome the scrutiny.
Line by line. What you are paying for, and what it assumes.
The part most likely to blow the estimate. That is the part that gets built.
A working slice of the riskiest piece. Running software you can click.
Written, with a recommendation and the evidence behind it.
The quote is fair and the plan holds up. You get the questions to push on before you sign.
Same outcome, less scope, different sequence, costed.
Sometimes the prototype shows the idea needs more work before anyone writes the cheque.
I write whichever one the ten days points to.
I've been shipping software for over twenty years, the last ten leading engineering, product and design.
For the last two, I've been heads-down with AI. Claude in my editor, Claude Code in the terminal, agents stitched into my day-to-day. It's why one person can build the risky part of your idea inside ten working days.
I built and shipped Vertera solo: a live healthcare platform with native iOS and Android apps, a clinician dashboard, PROMs, and compliance tooling for HIPAA, GDPR, ISO 27001 and SOC 2. That is the kind of build agencies quote six figures and six months for.

Fixed price, fixed time. If you carry on with me afterwards, it comes off your first embedded month.
Ten working days. Credited in full against your first embedded month if you carry on with me.
Working software for the riskiest slice, a line by line read of the quote, and a written verdict. You own all of it.
The ten days answer one question: is this quote worth signing. Building the part that carries the risk is enough to find that out.
Then I write that, and you sign with more confidence than you had. It happens, and it is why the verdict is worth paying for.
The deliverable is fixed before we start, and the risky slice is agreed on day three.
No. The quote and a conversation with you are enough. Whether you tell them is your call.
You do. All of it. Standard work-for-hire terms.
Whatever the verdict says. If you carry on with me, the fee comes off your first embedded month at £8,500.
No. Start with the call and tell me roughly what you are looking at. I only need the quote itself once we agree the ten days are worth doing.
Usually within days of the call. Two slots at most, so first come first served.
Ten working days, £5,000 fixed, credited against your first embedded month.
