Bay Commercial Bank

What Bay Commercial Bank does

Bay Commercial Bank, operating under the legal name United Business Bank, is a California-based community bank founded in 2004 and headquartered in Walnut Creek. The institution provides full-service commercial and consumer banking with a documented focus on small businesses, labor unions and labor organizations, individual consumers, and commercial real estate developers/investors. Core product lines span business and personal deposit accounts (checking variants, savings, money market, CDs, IRAs, HSAs), SBA 7(a) and 504 small business lending, USDA Business and Industry loans, commercial real estate and construction loans, equipment financing, business term loans, business credit lines, and merchant card processing. A differentiated Labor Services Division serves union and labor communities with specialized banking products.

The bank's technology platform is conventional community-bank infrastructure rather than a proprietary AI-driven stack. It comprises Business Online Plus (web-based account management, transfers, bill pay), mobile banking applications for business and personal customers, remote deposit capture / Scan-A-Check, ACH origination, wire transfer services, lockbox, positive pay fraud prevention, e-statements, and courier services, distributed alongside a physical branch and statewide ATM network. Distribution is omnichannel — relationship-based branch and SBA-lending-officer sales supported by digital channels and CDARS via an IntraFi Network partnership that enables multi-million dollar FDIC-insured deposits through a single relationship.

The revenue model is traditional bank economics. Primary streams include net interest income from commercial real estate, construction, SBA, USDA, equipment, term and personal loans; recurring fees and monthly maintenance charges on deposit accounts; transaction-based fees from cash management (merchant processing, ACH, wires, lockbox, courier, positive pay); interchange and annual fees from credit card programs; and interest-rate differentials on interest-bearing deposits. GTM is sales-led and relationship-driven, with SBA lending as a flagship origination channel and community/union outreach as a primary acquisition motion. The bank holds a 5-Star Bauer Financial rating, the highest category from that independent rating firm.
