What Keystone Bank does
Keystone Bank is a community bank founded in October 2018 in Bee Cave, Texas by Jeff Wilkinson, now operating as a division of Third Coast Bank following the February 2026 acquisition of its parent, Keystone Bancshares, by Third Coast Bancshares (NYSE: TCBX) in a $123 million transaction. Pre-merger, the bank served Central Texas from three branches (two in Austin, one in Ballinger) and a loan production office in Bastrop, with $1.02 billion in total assets, $812 million in loans, and $844 million in deposits as of mid-2025, supported by 80+ employees. Combined with Third Coast, the entity now holds over $6 billion in assets and operates a statewide Texas footprint plus a 50-state mortgage operation.
The bank's product set spans personal banking (Rewards Checking up to 4.65% APY, Rewards Savings up to 3.90% APY, CDs, home loans) and business banking (Small Business Checking, Business Analysis Checking, The Impact Account for nonprofits, Money Market, SBA loans, Commercial Real Estate loans, Lines of Credit, Term Loans, Acquisition Loans, Letters of Credit, Treasury and Liquidity services). The technology stack is largely vendor-built: Kasasa powers the digital banking platform and rewards programs, Mastercard Finicity delivers the Insights account-aggregation and budgeting feature, Early Warning Services provides Zelle P2P payments, and Jack Henry supplies Treasury Pro for commercial cash management. Mobile banking on iOS and Android offers biometric login, card controls, and real-time alerts; the website is WCAG 2.2 Level AA certified through AudioEye.
Revenue is generated primarily through net interest income on the loan portfolio (commercial real estate, SBA, business term loans, residential mortgages) funded by deposits, supplemented by account maintenance fees, loan origination and service fees, and treasury management fees. The go-to-market motion is relationship-based community banking targeting SMBs, entrepreneurs, nonprofits, and individual consumers in western Travis County and the Hill Country, differentiated by local decision-making, faster turnaround than national banks, and active community sponsorship and engagement.

Emerging players
