Yes. You can change your mind anytime up until a fundraise closes and you will receive a full refund, including any fees. Unfortunately, investments cannot be cancelled once the fundraise closes.
You'll receive a five-day notice via e-mail when a fundraise is about to close. Additionally, we put a 7 day warning on the fundraise page to let investors know that it will be closing soon. You can cancel at any point up until the fundraise closes.
Once the minimum funding target is met, many companies do a "rolling close", where investments that have successfully applied to invest are executed and funds are transferred, but the round is still open to receive new investments. You'll still receive a five-day notice if this occurs. Once your funds are transferred to the company, you no longer can cancel your investment or obtain a refund.
