What is a pro rata right?
Pro rata rights give an investor the right, without the obligation, to invest in later rounds to keep its ownership percentage. An investor that owns 10% of a company can buy 10% of the next round and hold its stake steady. Venture investor Fred Wilson has called it the most important term an investor can negotiate, because it pays off on the upside.
Why it matters to a revenue leader
Pro rata rights shape who is in the next round before it starts. When existing investors take their full allocation, new investors read it as confidence; when they pass, new investors ask why. Insiders often decide based on the latest sales results, so for a revenue leader the quarter before a raise carries extra weight.
Example
Fictitious numbersA seed investor owns 8% of a company raising a $25 million Series B. Its pro rata allocation is $2 million. If it invests, its ownership stays at 8%; if it passes after a weak quarter, the new lead will want to know the reason.
"Which of our investors plan to take their pro rata in the next round, and what sales results will they want to see first?"
