Starling and Carta Shift Focus to Annual Recurring Revenue Amid Fintech Evolution

Annual recurring revenue is everywhere in fintech right now. Companies like Starling and Carta have made ARR a centerpiece of how they talk about their businesses — not just to investors, but to the market at large. The pitch is simple: forget the funding round, look at the revenue line.

It’s a real shift. For years, fintechs leaned hard on valuation headlines and capital raises to signal momentum. A $2 billion round was a story. A $4 billion valuation was a story. Whether the underlying business could sustain itself? That was kind of a secondary concern, at least publicly. Cheap capital made that possible. Investors were willing to bet on potential rather than proof. But that era’s pretty much over, and the metrics that matter have moved with it. Margins, customer retention, cash flow — these are what serious money is watching now. ARR fits neatly into that framework because it gives a number that, in theory, speaks to actual customer behavior and recurring demand rather than speculative future upside.

Why ARR Gets Messy Fast

The problem is that ARR isn’t as clean as it sounds. Two fintech companies can report the same ARR figure and be running fundamentally different businesses. A company locked into multi-year enterprise contracts and a platform collecting tiny per-transaction fees can both land on the same annual number. Same figure, totally different risk profiles, different customer dynamics, different revenue predictability. And yet, side by side in a pitch deck or press release, they look equivalent.

That gap matters. Investors trying to compare fintechs on ARR alone are basically comparing apples to something that’s technically a fruit but grown in completely different conditions. The AI sector has made this worse, not better. AI companies have been reporting revenue growth at speeds that look almost theatrical, and that pace has warped expectations around what ARR should look like and how fast it should climb. Fintech firms now operate in a world where their ARR growth gets benchmarked against AI darlings, which isn’t really a fair fight.

So the debate inside the industry is pretty real: what does ARR actually mean? Is it contracted revenue? Active paying customers? Annualized figures based on last month’s transactions? Projected run rates that assume everything stays flat? Companies can choose, and the choice matters enormously. Without disclosure of those details, ARR is basically a number in search of a definition.

What Transparency Actually Requires

For ARR to hold up as a serious metric, companies need to go further than just reporting the number. The period of calculation matters. Customer concentration matters — if 60% of ARR comes from three clients, that’s a different story than 60,000 customers each paying small amounts. Revenue consistency across quarters matters. How new customers ramp up matters, because a signed contract and an active paying account aren’t the same thing.

Starling and Carta putting ARR front and center is a signal, but it’s only useful if the supporting detail follows. Fintech firms that want to be taken seriously in this environment can’t just drop a headline ARR figure and walk away. The investors worth impressing will dig into what’s contracted versus what’s realized, what’s growing organically versus what’s held together by a handful of large deals.

And there’s a real risk here. ARR could go the way of other metrics that sounded rigorous until everyone started gaming them. The valuation boom showed what happens when numbers get detached from business reality — things look great until they very much don’t. Fintech went through that cycle. It doesn’t want to repeat it.

The sector is in a different place now. Regulated operations, institutional backing, actual customer bases with transaction histories. That’s real. But real only counts if it’s reported clearly. Transaction volumes fluctuate. Customer ramp-up speeds vary. These dynamics hit ARR in ways that a single annual number won’t capture on its own.

Fintech’s maturation is genuine — but maturation means accountability, not just a new metric to headline. Companies that break down their ARR with actual detail, that show what’s driving the number and what could disrupt it, will probably earn more trust than those who treat ARR as a marketing line. The ones who don’t will find that sophisticated investors have seen this movie before.

Carta and Starling are betting that revenue transparency wins. The industry is watching to see if the detail matches the headline.
