There’s a conversation happening in boardrooms, co-working spaces, and investor meetings across London right now – and it’s one that would have seemed premature just a few years ago.
Founders are talking about compliance. Not grudgingly, not because a lawyer told them to, but because the market has made it unavoidable. The businesses that treated regulatory infrastructure as an afterthought are the ones struggling to raise, struggling to scale, and struggling to explain themselves in due diligence. The ones that got it right early are pulling ahead.
Two areas in particular keep coming up. The first is payment licensing – the regulatory authorisation that any business touching money movement, subscription billing, or embedded finance needs to have properly sorted. The second is HR infrastructure – the people-operations layer that growing businesses consistently underinvest in until it becomes expensive not to.
Zitadelle AG’s payment licensing practice has been handling the first problem for founders across the UK and Europe – helping businesses understand what authorisations they actually need, how to structure applications efficiently, and how to build a regulatory position that holds up as the business grows.
The payment licensing problem nobody warns you about
Here is something that catches a surprising number of UK founders off guard: the point at which your business needs a payment license is not always obvious, and the consequences of crossing that line without one are not trivial.
Marketplaces, SaaS platforms with billing components, businesses holding customer funds even temporarily, and companies facilitating payments between third parties – all of these can find themselves in regulated territory without having made a conscious decision to enter it. The product evolves, a feature gets added, and suddenly the legal and regulatory picture is considerably more complicated than it was six months ago.
The FCA’s authorisation requirements are clear in principle and complex in practice. What constitutes payment initiation, e-money issuance, or account information services – and which of these your product actually touches – is a question that deserves a precise answer before you’re in a fundraising process and an investor’s legal team is asking it for you.
Getting ahead of this isn’t about being conservative. It’s about having optionality. A properly licensed business can move into new markets, attract institutional clients, and close commercial partnerships that an unlicensed one simply cannot.
The HR infrastructure gap is bigger than most London founders admit
Ask most founders how their HR function is doing and you’ll get a version of the same answer: fine, we’re managing, we’ll sort it properly when we’re bigger.
The problem is that “when we’re bigger” is precisely when HR problems become expensive. A misclassified contractor who’s been working with you for two years. An employment contract that doesn’t reflect current obligations. A performance management process that nobody followed because it was never properly documented. These aren’t hypothetical risks – they’re the standard catalogue of issues that emerge in fast-growing businesses that treated people-operations as secondary to product.
London’s labour market is competitive, sophisticated, and legally complex. Employees know their rights. Contractors know the IR35 rules. Senior hires ask pointed questions about equity, notice periods, and what happens if things don’t work out. The businesses that handle these conversations well – because they’ve built the infrastructure to handle them properly – close better hires and retain them longer.
The ones that wing it find out the cost of winging it at the worst possible time.
The businesses getting this right are already pulling ahead
The London fintech and business growth story of the next few years will be written by the founders who understood something their peers didn’t: that compliance infrastructure and people infrastructure aren’t overheads to be minimised. They’re competitive advantages to be built.
Payment licensing sorted before the product launch. HR processes built before the headcount doubles. Regulatory and people foundations designed for where the business is going, not just where it is today.
It’s not the most exciting conversation to have. But it’s increasingly the most important one.
