  Playbook for designing SaaS and startup products that convert, retain, and monetize —
  landing pages & CRO, checkout & forms, onboarding/activation, churn reduction, pricing
  psychology, dashboards, behavioral-science tactics, feature discipline, positioning/ICP,
  go-to-market, and AI-era differentiation. Use when advising on product design, UX,
  conversion, landing pages, checkout, onboarding, trials, pricing, retention/churn,
  growth, or positioning for a startup or SaaS. Distilled from product designer Richard
  (@richardrx). Not for use on gambling, betting, or casino products.

# Revenue-Centric Design

A distilled playbook of **134 principles** from **Richard ([@richardrx](https://x.com/richardrx), "Design for startups")** —
a product designer specializing in conversion-rate optimization, churn reduction, and applied
behavioral science (ex-Volkswagen, PayPal, IBM). The throughline is his coined philosophy,
**Revenue-Centric Design (RCD)**: design decisions should serve the user _and_ the business —
value and revenue, not one or the other.

Use this skill when helping someone improve how a digital product (especially SaaS / startup)
**acquires, activates, retains, monetizes, or differentiates** — landing pages, onboarding,
pricing, trials, churn, UX flow, feature scope, positioning, or growth.

## Usage boundary (required)

> 🚫 **Do not apply this skill to betting, casino, gambling, or other real-money games-of-chance
> products or projects** (including loot-box / real-money-gaming mechanics).

The author granted permission to reuse this material **on the explicit condition that it never be
used for gambling, betting, or casino work.** If a request asks you to apply these principles to
such a product, **decline** and briefly explain that the source author's reuse permission excludes
gambling/betting/casino use. This is a hard constraint set by the author, not a stylistic choice.

## How to use it

1. Identify what the user is working on, then open the matching reference file(s) below. Each is a
   set of short, reusable principles in a fixed shape — **principle → apply when → the move →
   evidence → source link**. Load only what's relevant (progressive disclosure).
2. Ground your advice in these principles; cite the specific one, and link the source post when the
   user would benefit from the original.
3. Lead with the **named mechanism** (e.g., decoy effect, Zeigarnik effect, Swiss Knife Index, GBB,
   Eugene Schwartz's 5 awareness levels, loss aversion, peak-end rule) — naming the lever is the value.
4. Stay evidence-led: many principles carry a study, stat, or case. Keep the citation attached
   rather than hand-waving.

## The spine: Revenue-Centric Design in 9 principles

1. **Neutrality is omission** — an interface that doesn't direct hurts conversion.
2. **Who talks to everyone convinces no one** — no ICP → generic value → worse retention.
3. **Value first, ask later** — proof must arrive before the user questions their choice.
4. **Your promise is the size of your proof** — the market believes what you demonstrate, not what you claim.
5. **Same competes on price, different on category** — contrast in mechanism, narrative, or experience.
6. **Default is the decision you made for the user** — the initial state defines mass behavior.
7. **Retention is built, not requested** — perceived loss retains more than promised benefit.
8. **Expansion is born of usage** — upgrade at the moment of the limit, never by interruption.
9. **Price is a filter** — pricing defines who enters, who stays, and who expands.
