After the next "closing" of the offering. Every investor whose investments have “cleared” by the time of the closing will be included in a disbursement. A company can conduct a series of “closes” (withdrawals of funds) throughout the duration of the campaign. If a company has a minimum capital amount that they must raise before they can withdraw funds from their escrow account then there may be a wait before their first closing - check their Offering Circular (for a Reg A+) or their PPM (for a Reg D).
After the "closing" the issuance of your securities will begin and you will be sent an email by the company you invested in. You will receive a communication when your securities are issued, along with instructions on how you can directly access your securities.
