All campaigns on FundedByMe have a minimum goal to reach before it can be deemed 'successful' - we show that minimum goal as 100%. They also have a maximum goal, based on the number of shares available, which will show on the campaign as 'overfunded'.
Once the campaign you have shown an interest to invest in reaches 100% you will receive an email confirming that it has reached its target. Part of this email will be the payment information, prompting you to make the payment to the business you are investing in's bank account.
If a campaign closes after 45-days and has not reached 100% of its minimum goal, you will also receive an automated email from FundedByMe telling you this. In this case your investment interest will be canceled and there are no further actions required from you.
