Plastiq, a B2B payment platform powering the small and midsize business economy, went public via a SPAC merger with Colonnade Acquisition II in a $480m deal. “We are excited about this important milestone of entering the public markets through a combination with Colonnade. For too long, SMBs have been neglected from financial services. As a public company, we plan to continue to invest in opportunities to scale the business with a growing product suite that enable us to provide SMB owners with access to sufficient, on-demand cash flow, which is a critical component to grow their businesses," Eliot Buchanan, Plastiq CEO.
