Pro-rata rights
The right (not the obligation) for an existing investor to participate in future rounds sufficient to maintain their ownership percentage as the company issues new shares.

In plain English
If a Series A investor owns 10% and you raise a Series B, they can put in 10% of the new round to stay at 10%. Prevents forced dilution of early believers.
Example
Seed investor owns 8% at $1M invested. Series A raises $10M — pro-rata check is $800k to stay at 8%. Investor declines → their stake dilutes to ~6% post-round.
Why it matters
Pro-rata is table-stakes for institutional seed funds. Some angels ask for it too. Founders should reserve pro-rata for investors who are actually adding value beyond the check — everyone else takes it in the standard SAFE/note.
Common mistakes
- Granting super-pro-rata (2x, 3x) to early investors — clogs future round allocation
- Not tracking pro-rata rights on the cap table — they surface as a surprise mid-Series-B
- Confusing pro-rata rights (participate in future rounds) with anti-dilution (get made whole on down rounds)
