# Lesson 6: Know who it's for

> Personas put a face on the work; accounts put revenue on it. ARR and churn are how product connects to money.

Two questions anchor every build decision: **who is this for** (persona) and **what revenue is at stake** (account).

## Personas: the "who"

A **persona** is a named archetype of a user with goals and pain points: "Keyboard-first Kate, a PM who lives in shortcuts," not "users." Personas force the *who is this for?* question before you build, which is the cheapest possible guard against building for yourself by accident. Solo founders are their own heaviest user; that's exactly why the discipline matters.

Link feedback to personas and patterns appear: if every export complaint comes from the data-analyst persona, you know who to interview before you spec.

## Accounts: the "how much"

In B2B, an **account** is a customer organization. Ten users at one account is one renewal decision, not ten. Accounts carry the money math:

- **ARR**: annual recurring revenue; the number you and any investor actually track.
- **Health score** & **churn risk**: leading indicators of that ARR walking out the door.

**Churn** is the silent killer of early SaaS: you can't out-acquire a leaky bucket. Feedback linked to a high-ARR, high-churn-risk account is not the same priority as the same words from a free-tier user, the Golden Thread is how you see the difference.

## Do it now

1. On [Personas](https://productos.ca/documentation/pages/workspace/personas), create or confirm one persona that matches a real user: name, goal, one pain point.
2. Link your Lesson 2 feedback to it.
3. Glance at [Accounts](https://productos.ca/documentation/pages/workspace/accounts): find the ARR and churn-risk columns (hover the ⓘ on either). If you have even two paying customers, add them.

> **Solo-founder shortcut**

>   Two personas is plenty to start: your core user and your buyer (sometimes the same person, knowing <em>that</em> is also a finding).
