We do not hand you an AI score.
We hand you something real enough to test.See the work first
One fictional idea. One real finished package.
Leadkeeper shows the messy starting idea, working prototype, blunt evaluation, three validation tests, and the exact boundary between what was included and what was left out.
The delivery
Enough to learn. Nothing added to look impressive.
Blunt evaluation
What is clear, what is weak, what we had to assume, and what is most likely to fail.
Test plan
Three specific tests you can run with prospective users instead of collecting vague opinions.
Files you own
Source ZIP, setup instructions, one revision, and a Cloudflare preview hosted for 60 days.
How it works
One week from messy idea to testable link.
- Day 0You answer the brief.
We check the idea fits a focused web prototype.
- Day 1We lock the workflow.
You know exactly what we are and are not building.
- Days 2-6We build and pressure-test.
The prototype and evaluation are created together.
- Day 7You get the link and files.
One revision is included after delivery.
Who this is not for
Not a production app in disguise.
Not for people who need a production app, login system, payment processing, app-store launch, or unlimited revisions. The job is to learn whether one core workflow deserves a real build.

Questions
Straight answers before you apply.
How long does a prototype take?
Seven days from an approved brief. Day 0 you answer the brief, day 1 we lock the workflow, days 2-6 we build and pressure-test, and day 7 you get the clickable link and source files.
What does the $499 include?
One focused clickable web workflow, a blunt evaluation and test plan, one revision, the source ZIP with setup instructions, and a Cloudflare preview hosted for 60 days.
When do I pay?
Not when you apply. We first confirm that a useful one-workflow prototype can be defined, then send an invoice. The seven-day build starts after scope approval and payment.
Do I own the code?
Yes. You receive the full source ZIP and setup instructions. No equity, lock-in, or mandatory retainer.
Is this a production-ready app?
No. It is a clickable prototype built to test whether the core workflow is worth a real build. It excludes production authentication, payments, sensitive customer data, and app-store releases.
What happens after the 60-day preview?
You can launch on your own domain for a one-time $250, and optionally keep managed hosting for $49/month with deployment management, DNS upkeep, and limited small changes. Cancel any time.
