What is a seed round?
A seed round is an early funding round used to prove the product and win the first customers. It is often the company's first outside capital, raised from friends and family, angel investors or early-stage funds, frequently on SAFEs or convertible notes. Founders typically size it to fund 12 to 18 months of work toward the milestone that makes the next round possible.
Why it matters to a revenue leader
At seed there is rarely a sales team, so the founder sells. The round buys evidence of paying customers, a repeatable reason they buy and early signs that they stay. A revenue leader who joins at or after seed inherits whatever proof those first deals created, so separating wins from the founder's network from wins a team could repeat is the first diagnosis.
Example
Fictitious numbersA founder raises $2.5 million at seed to fund 18 months. The goal agreed with investors is 15 paying customers and $1 million in ARR before raising a Series A. At month 12 the company has 9 customers, and 7 of them came through the founder's own contacts.
"Which of our first customers would we have won without the founder in the room?"
