“Can a small Seattle community bank with a modern core become a credible sponsor bank for embedded consumer lending and deposits?”
Founded 1999 as Seattle Savings Bank, a boutique community bank serving families, business owners and family offices around Puget Sound. In the early 2020s, the bank rebuilt on an open-API, cloud-based core and extended into embedded finance under a 'Partner Banking' brand, positioning itself as a sponsor bank for fintechs, marketplaces and consumer brands — including a consumer-facing CD rate marketplace, CD Valet, launched in 2022. It operates a California consumer-lending DBA called Partner Lending Solutions, signaling that its embedded-lending BaaS business is distinct from its community-bank balance sheet.
