Most launch advice is written by people selling you a dream. This isn't that.

Build Then What is a 65-page playbook for indie builders sitting on an app that shipped and then went quiet. It's built on a real app that had 584 visitors, four-minute average sessions, and zero signups — and walks through every leak that was actually killing conversions, most of which had nothing to do with the idea.

Three parts: Fix the App (make a stranger understand it in five seconds), Get It Seen (the audience playbook, a content engine, and a first-paid-ads playbook), and Optimize (chase the funnel, not vanity metrics). Every phase ends with a "Do This Now" walkthrough plus the exact steps run on the real case-study app. Includes 8 copy-paste AI prompts and the full teardown.

No guaranteed-riches promise. Just an honest diagnosis from someone one step ahead of you.

Features

What's inside — the "feature" list (concrete, checkable):

A 65-page playbook in three parts — Fix the App, Get It Seen, Optimize — that moves you from "shipped and quiet" to "understood and bought"
A "Do This Now" walkthrough in every phase — literal, ordered steps you execute this week, not theory
A real "here's me doing it" box beside each walkthrough — the same steps run on an actual app, so you copy a pattern instead of guessing
The Audience Playbook — a 5-step system for finding where your buyers already gather and earning the right to be heard
The Content Engine — how to produce content at volume without burning out, including the repurposing multiplier (one idea → a week of posts)
The Paid Ads Playbook — how to run your first $200 ad test as an experiment that returns a real answer, with a diagnostic ladder for reading the results
All 8 AI prompts, copy-paste ready — grouped by phase, in the order you'll actually use them
The full case study — a real app with 584 visitors and $0, every leak found, every fix shipped, and what's still being measured
An exit checklist per phase — so you know when you're actually done, not just busy

Use Cases

Use cases — the "when do I reach for this" list:

You shipped an app and it went quiet. Traffic maybe, signups no. This is the core case — diagnose why strangers don't convert.
You've posted a lot on social and gotten nothing. The Audience Playbook and Content Engine explain why volume alone failed and what to do instead.
You're about to build and want to avoid all of this the first time. Part One is a pre-build sanity check on whether a specific person will actually pay.
You have visitors but a brutal bounce rate. Part Two's "walk your funnel as a stranger" finds the leak between "landed" and "signed up."
You're thinking about running ads and don't want to waste the money. The Paid Ads Playbook is a first-timer's guide to buying a clean answer instead of lighting cash on fire.
You're stuck on "what do I even post?" The Content Engine turns your audience's real questions into a repeatable content calendar.
You're not sure if the idea is dead or just the marketing. The whole book exists to separate those two — usually it's not the idea.

Retired IT pro turned solo builder. I design, build, and market AI-powered tools myself.

I'm a retired IT guy. I built several apps with AI tools and made $0 across all of them. Instead of quitting, I took my own app apart and wrote down every reason it wasn't converting. This is that teardown, turned into a playbook. I'm not promising you riches — I'm sharing what I found while I'm still in it.

Loved the brutal honesty. Instead of vague marketing advice, it gives you a concrete playbook to fix your funnel and messaging. Super actionable.
