“Can a construction estimating tool become the financial operating system for residential contractors?”
Founded 2016 as CostCertified, an estimating tool for residential contractors. Following Y Combinator in 2021, the company rebranded to Bolster and expanded from estimating into an end-to-end construction OS covering CRM, project management, presentations, and — critically for embedded finance — payments, business accounts, and (in roadmap) capital and corporate cards. The strategy is a classic vertical SaaS 'own the money layer' play: use estimating as the wedge, then monetize contractor cash flow via payments (Adyen) and lending.
Bolster discloses Adyen as its banking provider, according to the Embedded Finance Index 2026.
Bolster does not disclose a bank charter of its own; its banking services are provided through Adyen.
Bolster processes payments through Adyen. Disclosed money-movement rails: ACH.
Bolster's lending and capital products are provided by Adyen.
Bolster integrates with QuickBooks.
The Embedded Finance Index 2026 maps 7 layers in Bolster's stack: Payments / PSP (Adyen); Money movement (ACH); Banking / BaaS (Adyen); Card issuing (Adyen); Card network (Visa); Lending (Adyen and Bolster Capital (coming soon)); Accounting (QuickBooks).
Bolster is founded in 2016 and headquartered in Calgary, Alberta, Canada.
