A decade ago, opening a checking account meant a trip to a branch, a printed signature card, and a teller who knew your name. Today the fastest-growing bank in America has no branches at all, employs no tellers, and signed up most of its roughly 25 million customers from a phone. Digital banking and neobanks are financial services delivered entirely through apps, often by companies that are not legally banks themselves but partner with one behind the scenes. Chime alone reached about 25 million signups and $1.6 billion in revenue in 2024, according to Business of Apps, a scale that forces traditional banks to respond. For consumers and businesses, the branch has stopped being the default.
What separates a neobank from a bank
A traditional bank holds a banking charter, which lets it take deposits and lend under direct regulatory supervision. A neobank usually does not. Instead it builds a slick app and partners with a chartered bank that holds the deposits and provides the federal insurance, while the neobank owns the customer relationship, the design, and the features. This split is the defining structural fact of the sector.
That arrangement is why a neobank can move fast on experience while leaning on a partner for the regulated parts. It also explains the business model. Rather than charging monthly fees, most neobanks earn the bulk of their money from interchange, the small fee merchants pay each time a customer swipes the neobank’s debit card, a model Business of Apps describes in its analysis of Chime.
Digital banking, more broadly, also includes the apps and online services that traditional banks themselves now offer. The line between a neobank and a digitally transformed bank is blurring, a shift explored in this look at why digital banking is becoming the industry standard.
Why customers switched
The pull was a better experience at a lower cost. Neobanks built around fee-free checking, early access to direct-deposit paychecks, fee-free overdraft up to a limit, and large free ATM networks. For customers tired of surprise fees, the proposition was simple and concrete, which is why adoption skewed heavily toward younger users who do their banking on a phone.
Convenience reinforced price. Signing up takes minutes from a phone rather than a visit to a branch, and the app handles everything from deposits to disputes. The benefits of this model for everyday account holders are laid out in this piece on opening an account through digital banking platforms, and its reach into underserved groups is covered in this look at how digital banking improves financial accessibility.
The result is a generational shift. A large and rising share of Americans now treat a banking app, not a branch, as their primary financial home, and the migration has been quiet but steady, as this analysis of the customer migration reshaping retail banking describes.
The numbers behind the sector
The leading US neobank illustrates the trajectory. The table below consolidates Chime’s reported figures, which anchor the broader sector conversation.
| Metric | Figure | Note |
|---|---|---|
| Total signups | ~25 million | Cumulative since launch |
| Active users (2024) | 8.7 million | Engaged accounts |
| Revenue (2024) | $1.6 billion | Up about 31% year over year |
| IPO valuation (2025) | $11 billion | Rose to $18.4 billion on debut |

Read together, these figures show a company that grew users for years and only recently turned that scale into a public-market story. The gap between 25 million signups and 8.7 million active users also reveals the sector’s central challenge: turning sign-ups into daily primary accounts rather than secondary spending cards.
What it means for businesses
For businesses, neobanks matter in two ways. First, many now serve small businesses directly, offering app-based accounts, instant payouts, and integrated bookkeeping that traditional banks were slow to build. A founder can open a business account and start moving money the same day, without a branch visit or a relationship manager.
Second, the neobank model is a template. Any company with a large customer base can now embed banking features, a card, an account, instant payouts, into its own app through banking-as-a-service partners. That is reshaping how non-banks think about financial products, and it pressures incumbent banks to match the experience or risk becoming invisible plumbing behind someone else’s app.
The competitive response from traditional institutions has been to accelerate their own digital builds, a trend covered in this look at the future of global digital banking, because the alternative is ceding the customer relationship entirely.
The risks beneath the growth
The model carries real risks. Because most neobanks rely on interchange rather than fees, their revenue is tied to how much customers spend, which makes them sensitive to economic downturns. The partner-bank structure also creates dependency, since the neobank does not control the charter or the insurance directly, a point regulators have scrutinized after high-profile partner failures.
Profitability is the other open question. Many neobanks grew users fast while burning cash, and the path to durable profit runs through becoming a customer’s primary account, the one their paycheck lands in, rather than a secondary card. Which players have actually reached that point is examined in this analysis of where the profitable neobank players now sit.
Where the sector goes next
The next phase of US neobanking is about depth rather than reach. Having acquired tens of millions of customers, the leaders are racing to add products, lending, investing, savings, and credit-building, that deepen each relationship and lift revenue per user. A customer who borrows, saves, and spends through one app is worth far more than one who only swipes a debit card occasionally.
Consolidation is likely. Many smaller neobanks grew on cheap capital and now face a harder funding environment, which favors the few that reached real scale and a credible path to profit. The recent public-market debut of the category leader gives investors a benchmark, and it raises the bar for every neobank still private.
For consumers, the practical upshot is more capable apps and, eventually, fewer but stronger providers. The era of dozens of near-identical fee-free checking apps is closing, and the survivors will be the ones that became a genuine financial home rather than a second card, a convergence that continues to play out as covered in this look at the future of global digital banking.
The branch is not disappearing tomorrow, but its role has changed from default to backup for a growing share of Americans. The neobanks proved that millions would run their financial lives from a phone, and the lasting question is now which of them can turn that habit into a primary banking relationship that pays for itself.
