How much has Brex raised?

Brex raised over $1.5B in combined equity and debt capital across 11 rounds from 2017 to January 2025. Of that total, roughly $1.1B was equity (Series A through D-2) and the remainder was structured debt — balance-sheet capital used to fund card underwriting and corporate lending rather than operations.

The equity raises follow a steep ramp: $7M in 2017, $175M in 2018–2019, $250M in 2020, and $875M across 2021 alone. The debt raises — from Barclays, UBS, SVB, American Express, Bank of America, Citi, and TPG — reflect the capital-intensity of running a lending business inside a fintech software company. The January 2025 Citi/TPG debt round was non-dilutive and positioned Brex to reach cash-flow positivity without further equity dilution before the Capital One deal.

Brex never raised a formal down round — no equity was priced below the $12.3B Series D-2. However, the Capital One acquisition at $5.15B effectively realized a down-round outcome for investors who participated at the 2021 peak, representing a roughly 58% markdown to the last equity valuation.

Brex's earliest backer was Ribbit Capital, the fintech-specialist VC that led the Series A alongside Y Combinator. Greenoaks Capital appeared in the Series C and led the peak Series D-2 round, holding one of the largest equity stakes going into the acquisition. Tiger Global led the Series D at $7.4B — one of the last mega-rounds Tiger executed at growth-stage valuations before the 2022 correction.

Kleiner Perkins joined in the June 2019 Series C extension, lending Brex a tier-one Sand Hill imprimatur. DST Global and IVP participated in multiple rounds. Perhaps most notably, Peter Thiel and Max Levchin — co-founders of PayPal — backed Brex early, providing both capital and strategic fintech credibility. TCV, known for backing Spotify and Netflix, co-led the final Series D-2.

On the debt side, Silicon Valley Bank, American Express, Bank of America, Barclays, UBS, Citi, and TPG all provided structured financing. This diversity of debt providers — spanning traditional banks, a card network, and private equity credit — reflects Brex's hybrid identity as both a software company and a financial institution.

The $12.3B valuation was set in October 2021 at the height of a zero-interest-rate-policy environment that inflated SaaS and fintech multiples across the board. When the Fed began raising rates aggressively in 2022, growth-stage multiples compressed across the sector — Brex was not unique in this respect. The valuation was never formally marked down in a new equity round, so secondary market prices fell while the cap table held its last-round reference.

The June 2022 SMB exit also removed Brex's fastest-growing (if riskiest) customer cohort, slowing near-term revenue growth and signaling a multi-year rebuild toward enterprise. In hindsight, the pivot was the right strategic call — enterprise NRR reached nearly 140% and the business became cash-flow positive — but the transition cost time and suppressed near-term revenue growth multiples.

The $5.15B Capital One price — roughly 7x annualized revenue at a ~$700M run rate — is a rational strategic acquisition multiple for a profitable and growing software-plus-card business. For Brex CFO Erica Dorfman, the transaction represented a premium to public-market comps that made the financial logic compelling, even if the headline number stung relative to the 2021 peak.

Brex reached operating cash flow positivity for the first time in October 2025 — a pivotal milestone that management had flagged as the precursor to any IPO process. Net revenue retention in the enterprise segment reached nearly 140%, and overall revenue growth was tracking approximately 50% year-over-year as of August 2025, with annualized revenue hitting roughly $700M.

Brex had been mulling an IPO path — Bloomberg reported in February 2025 that Brex was eyeing $500M in 2025 revenue as it considered an eventual public offering. Pedro Franceschi's move to sole CEO in 2024 was partly framed as IPO preparation. The Capital One acquisition in January 2026 (closed April 7, 2026) ended the independent public-company track.

Under Capital One, Brex operates as a strategic subsidiary rather than a standalone public company. Public investors can now access Brex's economics through Capital One shares. Pedro Franceschi continues to lead the combined entity, and the product roadmap reportedly continues largely intact — Capital One's ownership provides a much larger balance sheet to fund continued growth.

Post-acquisition, Brex sits inside Capital One — a bank with roughly $100B+ in assets — which significantly expands its buying power relative to a VC-backed startup. Capital One's ownership means procurement processes are maturing fast: expect more formal vendor evaluation cycles, expanded security reviews, and legal due diligence compared to a pre-acquisition Brex deal.

The $235M January 2025 debt round from Citi and TPG suggests Brex was actively investing in product and infrastructure right up to the deal close — meaning technology refresh budgets and integration work are likely still in flight through 2026. Sellers targeting Brex's finance, engineering, or GTM teams should anticipate that budget owners are integrating Capital One's existing vendor relationships alongside Brex contracts, creating both displacement risk and expansion opportunity.

Brex reports into Capital One's commercial division (Frank LaPrade's org), so for larger enterprise deals, the approval chain now runs through both Brex leadership and Capital One governance. Champion relationships with Brex's CTO (James Reggio) for infrastructure deals, and with the CRO (Doug Adamic) for GTM tools, remain important for the initial land — but C-suite and Capital One sign-off are increasingly required for meaningful contract expansions.
