“Can a single subscription platform replace the entire financial back-office — tax, banking, payroll, bookkeeping, and benefits — for the 17M+ US solopreneurs filing as S Corps?”
Lettuce launched as a financial operating system purpose-built for US solopreneurs and single-member S Corps, bundling business formation, automated tax management, payroll, bookkeeping, and banking into a single subscription. Rather than building financial infrastructure in-house, Lettuce assembles a stack of embedded finance partners (Unit for banking, Gusto for payroll, Tight for bookkeeping, Formations for incorporation) to deliver enterprise-grade financial services to solo business owners. The strategic angle is replacing a fragmented combination of accountant + QuickBooks + payroll software + bank with one vertically integrated platform optimized around S Corp tax savings.
Lettuce discloses Unit as its banking provider, according to the Embedded Finance Index 2026.
Lettuce does not disclose a bank charter of its own; its banking services are provided through Unit.
Lettuce's payroll is powered by Gusto.
The Embedded Finance Index 2026 maps 3 layers in Lettuce's stack: Banking / BaaS (Unit); Payroll (Gusto); Spend / AP (Tight).
Lettuce is headquartered in San Francisco, CA (548 Market St., Suite 84232, San Francisco, CA 94104).
