Square
“Can Square become the complete financial OS for small and medium businesses by owning the full stack — payments, banking, lending, payroll, and tax — on a single vertically integrated platform?”
Square launched in 2009 as a card-reader hardware company democratizing payment acceptance for micro and small businesses. Over a decade it evolved into a full financial operating system for SMBs — layering in payroll, banking (checking, savings), lending, and corporate card products, culminating in the 2021 launch of its own FDIC-insured bank, Square Financial Services, Inc. The 2021 rename to Block Inc. at the parent level separated the Square SMB brand from Cash App (consumer) and other ventures. The embedded finance strategy is now deeply vertical: Square underwrites loans using its own transaction data, issues checking accounts through its own bank charter, and embeds payroll/retirement/tax services directly into the seller dashboard.
