The story

Founded in 2012, Plastiq pioneered credit-card-based vendor payments for SMBs — allowing businesses to pay suppliers by card even when vendors don't accept cards. After raising $472M+ and attempting a SPAC merger in 2022, Plastiq was acquired by Priority Technology Holdings and now operates as 'Plastiq, Powered by Priority.' The company expanded from pure bill-pay into embedded finance through Plastiq Connect APIs (enabling platforms to embed payment and working capital features) and added short-term financing for SMBs, positioning itself as a B2B payments and working capital platform rather than a simple payment bridge.
