## The short definition

One idea, plainly put.Co-Sale Right is a capital concept your team should define once. A loose definition misaligns budgets and reporting.

Right to sell alongside founder in third-party sale.

Co-Sale Right sits in Capital & Investing; it is a capital concept. Define it once and the reporting holds together.

## The mechanics

One idea, plainly put.There is no single setting for Co-Sale Right. It bends to the audience, the channels, and the wider plan.

Co-Sale Right is not a switch you flip. It names a moving idea, and the way it plays out shifts with the setup. A lean team running one paid channel applies Co-Sale Right differently than a brand running ten. Use Co-Sale Right loosely and teams pull apart; pin it down and the math lines up.

The working rule is plain. Agree what Co-Sale Right covers first, then act on it. Skip that order and Co-Sale Right loses its shared meaning, and two teams end up measuring two different things. Worth a slow read.

## Where it shows up

Keep this in mind.Reach for Co-Sale Right when a real decision rides on it -- a budget, a metric, or a comparison. Otherwise it is reference.

Use Co-Sale Right when it changes an outcome. For capital & investing teams, that tends to be three recurring moments. With no choice live, Co-Sale Right is good to know, not to chase.

1. **Setting budget.** Co-Sale Right helps decide which channel gets the next dollar.
2. **Choosing a metric.** Co-Sale Right flags whether the number you report is causal.
3. **Comparing options.** Co-Sale Right evens out a comparison that would otherwise mislead.

## Worked example

Pick one definition.The example below traces Co-Sale Right through a real a PE-owned DTC brand scenario, with real limits and a number to read at the end.

Look at a PE-owned DTC brand. In a contribution-margin cleanup, Co-Sale Right drove the decision rather than sitting in a footnote. A baseline came first, then a single agreed meaning of Co-Sale Right, then the read: EBITDA margin lifted 6 points in a year.

Worked example for Co-Sale Right -- illustrative figures, RGM analysis

| Stage | The step taken | Why it mattered |
| Baseline | Logged where Co-Sale Right stood before the test. | Something concrete to compare to. |
| Define | Fixed one meaning of Co-Sale Right for the test. | Two people, one meaning. |
| Act | A contribution-margin cleanup — one variable. | Cause and effect, isolated. |
| Result | EBITDA margin lifted 6 points in a year | A decision the data earned. |

Treat the Co-Sale Right figures as illustrative, labeled RGM analysis. Reuse the sequence, not the digits.

## Where teams go wrong

Keep this in mind.Most mistakes with Co-Sale Right share a root: the term gets reported as if it were exact when it is not.

- **One blanket rule.** Applying Co-Sale Right the same way everywhere. Split it by audience, channel, and business model.
- **No anchor.** Quoting Co-Sale Right without a starting point. Always pair it with a baseline.
- **Vanity focus.** Gaming Co-Sale Right instead of the result. Tie it to business value.
- **Apples to oranges.** Comparing Co-Sale Right across firms raw. Adjust for pricing and cycle before you read it.
