Starling's Edge Over Tide
Tide
Starling can afford to make business banking stickier because it owns the cheapest and most powerful part of the stack, the deposits. With a full banking license, SME balances sit on Starling’s own balance sheet, so it can pay interest, fund loans directly, and keep the spread between what it earns on assets and what it pays depositors. Tide, by contrast, relies on ClearBank and lending partners, which limits margin and product control.

That balance sheet matters most in credit. Tide offers Credit Flex and a lender marketplace, but partner led lending means economics are shared and underwriting sits partly outside Tide. Starling can originate and hold SME loans itself, which lets it bundle credit tightly with the primary account and price for retention, not just for referral revenue.
-
Deposits also make retention more mechanical. In UK neobanking, higher rates turned deposits into a customer acquisition and retention tool, because banks with their own balance sheets could win accounts through yield instead of paid marketing. Starling reported more than £12B of customer deposits in its 2025 annual report, giving it a large base to defend and monetize.

Monzo shows the middle case. It has its own license and earns net interest income from deposits and loans, but in the business segment it is still lighter on bookkeeping depth, while Tide is stronger in workflow software. Starling is the one combining licensed banking economics with a direct Tide substitute in software through its £7 Business Toolkit, plus extra reach through Engine.
The market is moving toward SME finance platforms that combine the account, the ledger, and the loan in one place. If Tide builds more proprietary credit, it narrows the gap, but licensed players like Starling start with a structural edge because every retained deposit can fund the next product, lower acquisition cost, and deepen the customer relationship over time.
