As soon as you submit a purchase on the Equivesto portal your money is transferred to a segregated account. The funds are held in this segregated account for the duration of the campaign. Once the campaign is over, the funds are released to the company if it was successful, or refunded to investors if it did not meet the minimum raise goal.
When investing, investors have a 48 hour back-out window, where investors can change their minds and ask for a full refund no questions asked.
