The most useful fact when comparing startup banking platforms is that most of them are not banks. They are software companies that build the account experience on top of chartered partner banks, and once you know that, the questions that actually differentiate them become obvious.
Who holds the money, and what that means for insurance
Deposits in these products sit at partner banks rather than with the platform itself, which is why deposit insurance coverage is described in terms of a network of banks and a sweep arrangement that distributes balances across several of them. This can extend coverage well beyond what a single account would carry, and the mechanism is worth understanding because it is contractual rather than automatic.
The questions to ask are which institutions hold the funds, whether the sweep is opt-in or default, whether it applies to your full balance or only part, and what happens to access if the relationship between platform and partner changes. Confirm current arrangements directly with each provider, because partner lists and coverage terms are revised and any figure written elsewhere ages quickly.
The real differentiators are controls and workflow, not the account
A business current account is close to a commodity; what separates these platforms is the operational software around it. Compare how spend controls work in practice: whether cards can be issued instantly per person or per vendor, whether limits and merchant categories can be set at issuance, whether receipts can be required and chased automatically, and whether approval flows exist for larger payments.
Then compare the accounting side, since this is where daily time is spent. Look at the depth of the ledger integration, whether transactions arrive categorised with receipts attached, whether the reconciliation is genuinely two-way, and how multi-entity structures are handled if you have more than one company. A platform that saves a bookkeeper hours each week is worth more than a marginal difference in yield.
Treasury, yield and the question of where idle cash sits
Most of these platforms offer some way to earn on idle balances, and the mechanism differs in ways that matter. Money held in a bank deposit and money held in a money market fund are different products with different risk and different insurance treatment, even when the interface presents them side by side. Establish which one a yield feature is actually using before deciding it is comparable across providers.
Also establish liquidity: how quickly funds move back to the operating account, whether there is a settlement delay, and whether any minimum applies. For a company with a payroll obligation, availability under pressure matters more than the rate, and this is the aspect a rate comparison never captures.
The failure modes worth researching before you commit
The recurring complaint across this entire category concerns account freezes and closures triggered by automated risk systems, together with the difficulty of reaching a person when it happens. Because the platform sits between you and the chartered bank, resolution can involve two organisations. Search recent user reports for exactly this, for each provider you are considering, and weight it heavily if your business has irregular flows, international counterparties or anything a risk model may find unusual.
The practical mitigation is independent of which you choose: maintain a second account at an unrelated institution with enough balance to cover payroll and critical payments. This is inexpensive insurance against a category-wide risk, and companies that have lived through a freeze describe it as the lesson they wish they had learned earlier.
