PAY TO PLAY
“Pay to play”, specifically in the tech ecosystem, refers to a sort of provision that effectively punishes investors for not participating up to their full pro-rata percentage. These provisions come in a number of forms, from anti-dilutive formulas in a dilutive financing event to converting preferred stock to common stock if the investor doesn’t fully invest for their pro-rata ownership.
