Growth Rate (y/y)
Sacra estimates that Brex hit $319M in net annualized revenue in 2023, a 48% increase from 2022 when they hit $215M and grew 12%.
Their acceleration was driven primarily by the 302% year-over-year growth of revenue from deposits, which grew from $26M annualized in 2022 to roughly $105M annualized in 2023. Brex's business checking product was one of the biggest beneficiaries of the shutdown of Silicon Valley Bank shutdown, which drove their total assets from $4B to $7B.
Brex makes most of its revenue from interchange fees when its customers use cards for transactions. Other sources of revenue include seat-based fees from Brex’s financial management SaaS, fees from bank partners where Brex parks its customers’ cash, and transaction revenue from Brex's bill pay product.
Unlike Amex, which charged $300-600/year for a corporate card, Brex gave away cards for free and monetized transaction volume at a roughly 2.7% interchange rate.
Brex’s free card served as a wedge to get into early stage companies like its fellow Y Combinator batchmates, and then its interchange model allowed it to index on the upside of those companies as they grew similar to YC’s venture model.
Brex based their credit limits on how much cash startups had in their accounts, giving startups 10x-20x higher credit limits, and waived off the monthly fee, making money through interchange fees, much like consumer neobanks like Chime and Dave.
Brex collects roughly 2.8% on the transaction volume that goes through their platform as gross revenue—after the interchange is split, they end up with about 55% gross margins. Compare that to a purely expense management product like Divvy (now part of Bill.com) with about 80% gross margins, or AmEx at ~65%.
Last year, Brex launched financial and software products complementing its corporate cards to eat into more of a startup’s financial stack, such as expense management, bill payment, and cash management, where they can make money through a SaaS-style subscription fee, reducing their reliance on interchange fees.
Brex found initial traction by indexing on the core problem facing all startups/SMBs: unlike established companies, they struggled to get corporate cards from traditional card companies like AmEx and furnished personal guarantees by founders for cards with low credit limits, even though they might have $100K or $1M in their bank account. On top of that, getting a card involved excessive manual paperwork, a long waiting time, and high monthly charges.
Gradually, Brex layered on more and more features—banking, expense management, venture debt, travel management, financial modeling, and others—en route to building a Silicon Valley Bank-like suite of financial products for startup businesses, all built on top of their (mostly) proprietary infrastructure payments base.
Brex’s key products include:
Corporate cards: Brex’s core product with high credit limits for startups without any monthly or set-up fee.
Venture debt: Provides loans to startups at a 6% to 10% interest rate.
Brex Empower: Spend management software, tightly coupled with corporate cards, through which companies can build rule-based spending workflows, reimburse employee expenses, and review purchases.
Bill pay: Payment software for non-payroll, non-employee spend where companies can process invoices and pay their vendors digitally instead of manually processing invoices.
Brex sits at the center of the venn diagram of neobanks, companies offering corporate cards, and expense management companies—their biggest competitors among startups are the other 'overlappers' that are stitching together several functionalities into one integrated product.
The launch of Ramp in 2020 changed the economics of the “startup credit card” by replacing rewards with cash back and bundling in expense management SaaS, which created switching costs and incentivized teams to have only 1 credit card company—forcing Brex to launch its own expense management product to catch up.
By using only Ramp cards across the team, companies could manage all their expenses in one place rather than stitching together their spend across multiple cards.
Mercury jumped in front of Brex in the financial stack with their linked bank account and debit card—now they have their own Mercury IO credit card (via Lithic), which has the advantage of consolidating a startup’s finances in one interface.
In parallel, incumbents in the spend management category are broadening their product suites. For instance, Bill.com acquired Divvy in May 2021, Airbase launched a standalone bill pay product in June 2021, and Rho added expense management software in August 2022.
Brex is threatened by a growing number of vertical SaaS with cards and expense management focused on industries with high spend irrespective of revenue ala Parker and Juni (ecommerce), Convoy (trucking) and Flexbase (construction) as well as Deel-esque, ‘global-first’ card companies like Jeeves, Moss, YouTrip, Payhawk. Vertical SaaS companies can take ~1.75% on each transaction completed on their platform by issuing virtual or physical credit cards to their customers.
Brex is expanding horizontally by eating into more of its customers’ financial stack through software and moving up the stack from startups to sell into enterprises.
Financial management suite
Like Rippling, Brex’s underlying infrastructure allows them to build a compound startup with the pricing advantage of bundling across many SKUs and the integrated UX of all-in-one software. Brex already combines Bill.com ($8B) with bill pay and expense management, Navan ($9.2B) with travel, Pipe ($2B) with debt, and Mercury ($1.6B) with banking—they have the opportunity to expand even further, from loans to accounting to payroll to other services like vendor payments.
The US B2B payments market at $25T is thrice the size of the B2C payments market, but credit card adoption is very low, accounting for only 4% of payments. With its card-led spend management software, Brex has the opportunity to sell more software to its existing customers, capturing more of their business spend on its platform.
In 2022, Brex both made the decision to stop serving SMBs/startups and also launched Brex Empower—an enterprise product suite for large companies to streamline reporting, budgeting, and delegating spend.
It already has late-stage startups like Doordash, Classpass, and Scale as its customers and is looking to move to larger Fortune 1000 companies to sell into.
Pivot in sales motion
As Brex pivots to sell to enterprises, there is a considerable change in the sales motion with longer sales cycles, stricter compliance norms, and higher customer support expectations. Brex’s existing sales and customer support operations fine-tuned for startups may not work for enterprises.
Reliance on interchange fee
Since making the decision to stop working with SMBs, Brex has become even more indexed on revenue from venture-backed startups spending money on their corporate cards—which could be a problem in an uncertain economic environment where both venture fundraising and startup spending are down.
