One advantage of a SPAC compared to a traditional IPO is that it can be a faster and more efficient way for a company to go public. This is because the SPAC has already raised capital through its IPO, which is then used to fund the acquisition of a target company and take it public. Additionally, the SPAC structure allows for greater flexibility in terms of valuation and deal structure, as the sponsors have more control over the negotiation process with the target company. The SPAC also provides more certainty regarding valuation and equity raised. Disadvantages include founders' loss of control over the process and loss of visibility.
