LAUNCHED Playbooks

Stop researching. Start shipping.

The evidence library, distilled into build-order playbooks. Every step carries its grade, links to live apps doing it right, and ships with a copy-paste prompt your coding agent can implement in minutes.

One payment, lifetime access, every future playbook included. No subscription — we practice the one-time pricing we preach.

Built the way it tells you to build

This page follows its own playbook.

One price, stated plainly$129, once. No countdown, no fake discount, no "only 3 left" — pressure tactics are absent from the best-converting pages we audited, so they are absent here.
The fear, answered in writingPay once, own it forever, every future playbook included. If it is not what you expected, one email inside 14 days gets a full refund.
Graded, like everything we shipEvery step inside carries SOLID or CONTESTED — and when a number is company-reported rather than peer-reviewed, the step says so with a yellow dot.

Step 1 of 5 · Pick the trial length

SOLID

Seven days. It beat 14 and 30 on subscriptions and revenue.

Do thisSet the trial to 7 days. In the largest trial-length experiment published — 337,724 real users, randomized — 7-day trials produced +5.6% subscriptions and +7.9% revenue versus longer trials, with better two-year retention.

Green dot: peer-reviewed randomized experiment (Yoganarasimhan et al., Management Science 2023). The strongest evidence class we track.

Buy once

Secure Stripe checkout, $129. The receipt email is your key.

2
Sign in with that email

We send a six-digit code — no password to invent, no account to manage.

3
Ship each step

Work the checklist. Every step has a copy-paste prompt your coding agent executes, and live app examples to compare against.

What this is not

It is not a course, and it is not the research library — that stays free. The playbooks are the decisions, pre-made: the strongest-graded path through the evidence for each surface, in build order, with the weak spots labeled instead of hidden. If a step rests on company-reported numbers, the yellow dot says so. Nothing inside is folklore.

Is this a subscription?
No. $129 once, lifetime access, and every playbook we publish later is included. We sell the way the evidence says people prefer to buy.
What if the evidence changes?
The playbooks are living documents wired to the same library the site runs on. When a grade moves — a replication fails, a better study lands — the step updates and you see the change.
Refunds?
One email within 14 days, full refund, no questions. The fear of a bad purchase is exactly the anxiety our own research says to remove in writing.
Who is this for?
Founders and small product teams shipping real apps. If you want the full research trail instead of the decisions, the free library already has it.
