A down round happens when a company raises new equity at a lower price per share than its prior round. The mechanical effects are predictable: anti-dilution provisions kick in, founder and employee dilution accelerates, and the cap table absorbs significant repricing. The signaling effects are equally important, down rounds signal market or operational difficulty and can complicate hiring, sales, and future fundraising.
In the 2022 to 2024 correction, many companies that raised in 2021 at peak valuations needed down rounds or extension SAFEs to bridge to better fundamentals. Done well, a down round resets the cap table for the next phase of growth.
