Overview
Arc built a financial platform for technology companies: revenue-based financing, cash management, treasury products, and a marketplace for debt capital. Don Muir, Nick Lombardo, and Raven Jiang founded it in 2021, entered Y Combinator's Winter 2022 batch, and raised $31 million in equity alongside a $150 million lending facility.[8][25]
Arc's path to a July 2026 acquisition by Axos was shaped by one structural fact. Software could reduce manual work of serving startup finance teams, but deposits, payment rails, insured cash, and lending capacity still came from regulated institutions. Each product expansion increased the value of Arc's interface and the importance of its bank infrastructure.
Axos closed the acquisition on July 20, 2026. The price was not disclosed, and Arc told customers the same team and platform would continue.[2][3]

Founding Story
Don Muir came from corporate finance. He worked in consulting and late-stage private equity before pursuing his MBA in California.[9] Nick Lombardo also worked in private equity and banking in New York.
Muir and Lombardo met at Stanford GSB. They found a sharp contrast between finance for established companies and finance for the founders around them. Large borrowers could run a competitive process among banks. Early-stage software companies faced slow underwriting, dilution, and products designed for larger accounts. Muir told Fintech One-on-One: “that was my aha moment.”[10]
NFX met Muir and Lombardo before they had chosen a company name or precise direction. The investor backed the founders, their SaaS focus, and their ability to recruit partners such as Stripe.[8]
Raven Jiang joined as founding CTO, pairing the finance thesis with a technical co-founder.[9] Muir’s April 2023 Next Play presentation says Jiang studied computer science at Stanford, worked at Facebook and Tesla, and joined Muir and Lombardo at Stanford Business School. This is Muir’s account rather than Jiang’s own founding interview.[9]
The first product was Arc Advance. Arc raised a $150 million debt facility, built an underwriting model, and advanced capital against software companies' future revenue.[8] The team came out of stealth in January 2022 with $11 million in seed equity and joined YC's Winter batch. The original wedge solved an urgent financing problem while generating the customer and underwriting data needed for a wider finance platform.

What They Built
Arc’s launch announcement describes converting future revenue into upfront capital, using financial data to underwrite advances.[26]
Arc then added cash-management accounts and investments. Stripe’s customer case study describes Arc’s use of Stripe Treasury and its 2024 migration to Fifth Third Bank.[27] Arc’s current disclosures identify separate deposit, advisory and brokerage arrangements, including Atomic Brokerage and Pershing.[24]
The capital product also changed. Arc initially lent from its own facility. Muir said the company deployed a couple hundred million dollars, repaid the facility, and replaced direct lending with an asset-light marketplace in January 2024.[10] Borrowers uploaded financials and a data room. Arc matched them with banks and private-credit funds whose loan sizes, industries, collateral preferences, and risk limits fit the request.
The manual work inside that marketplace produced another product. Arc Intelligence parsed spreadsheets, PDFs, and presentations, standardized credit metrics, and helped lenders draft analysis. Arc’s November 2024 technical article said the capital marketplace had processed billions in loan volume and represented $4 billion in private-credit demand by November 2024; the company's own benchmark reported more than 99% accuracy for tasks labeled high confidence.[13] Those figures were not independently audited.
In 2025, that lender tool became F2. It spun out with its own company, funding, CEO, and roadmap, while Arc launched Archie for startup finance teams.[4][14] Arc had evolved from one underwriting model into two finance-software businesses serving opposite sides of the credit market.
The acquired product continues to develop. By this October 2026 review, Arc’s developer documentation offers read-only REST and command-line access to company financial data; its MCP connector is marked coming soon. Archie’s product page advertises accounting, banking and spend data, alerts, scenario planning and reports. These are current product claims, not proof of accuracy or complete cross-provider coverage.[19][20]
Market Position
Target Customers
Arc first targeted premium, early-stage B2B software companies with recurring revenue. That focus made future revenue easier to model and kept distribution close to YC and venture funds.
Muir said Arc’s customer base expanded to pre-IPO companies after the 2023 bank crisis, with larger clients retaining several bank relationships.[10]
Market Size
Public market figures describe adjacent pools and cannot establish Arc's revenue opportunity. TechCrunch cited a roughly $30 billion venture-debt market in January 2024.[12] Arc later called its marketplace a $4 billion platform processing billions in loan volume.[13] The buyer said Arc could help it reach millions of underserved US small businesses, but Arc historically focused on technology and growth companies.[1]
Competition
Arc competed on breadth and specialization. Mercury built startup banking and treasury. Brex combined cards, spend, and cash management. Pipe and Capchase targeted recurring-revenue financing. Traditional banks supplied regulated accounts and credit.
Product lines kept converging. Ramp added Treasury in January 2025, pairing a bank account with money-market investments.[17] Mercury's own October 2025 comparison described a category where business accounts, expanded FDIC coverage, cards, invoicing, bill pay, expenses, accounting integrations, yield, and capital access increasingly came in one package.[18]
Arc's product sequence suggests an advantage in vertical context. Startup cash accounts supplied borrowers to the debt marketplace; marketplace data supplied lender software. Its constraint was institutional. Cash-management accounts and execution depended on banks, brokers, or payment partners. Reporting software alone did not require a bank balance sheet. A chartered bank could combine Arc's software with its own balance sheet, nationwide distribution, and regulatory infrastructure. Axos identified exactly that combination in announcing the deal.[1]
Trovata now advertises normalized bank and ERP data, cash forecasts, scenario modeling, and executive reporting. Its platform also markets a multibank portal to banking partners. An independent cash view is therefore an existing category, not a gap created by Arc’s acquisition.[21][22]
Business Model
Arc Advance used a lending facility to fund advances against future revenue.[8] Marketplace fees, treasury economics, interchange, software subscriptions, and referral revenue were not publicly broken out. Arc’s current pricing page lists an annual paid Premium membership, including Archie access, and custom Enterprise pricing; it does not disclose a fixed Premium price on the observed page.[23]
Arc raised $31 million in disclosed equity: $11 million in the seed round and $20 million in its Series A.[8][25] Its larger financing totals included the lending facility, which funded customer advances rather than ordinary payroll and software burn. Combining debt and equity as if both were venture funding would misstate the economics.
No audited revenue, net interest margin, take rate, credit losses, retention, or profitability data was disclosed. The acquisition price was also undisclosed, so investor returns cannot be inferred.
Traction
Arc’s August 2022 founder announcement described a community of over 1,000 founders and tens of millions deployed in advances.[25] A community count does not establish paying accounts or retained revenue.
A post-crisis presentation cited thousands of sign-ups and hundreds of millions in annual gross transaction volume.[9] These are founder-supplied measures, and the company did not publish cohorts, active-account counts, deposits, or net revenue.
Post-Mortem
Arc remained operational through the sale. Its post-mortem asks why a bank owner made sense after the company reported customer growth, changed its capital model, and separated a second product.
Wedge: direct lending supplied data and customers
Revenue financing gave Arc an urgent entry point and a way to learn underwriting. The remedy for its balance-sheet burden was explicit: repay the $150 million facility and turn the lending operation into a marketplace.[10] That reduced capital intensity while preserving borrower relationships. It also left Arc coordinating regulated lenders rather than replacing them.
Shock: SVB pulled cash management forward
The failure of Silicon Valley Bank brought urgent demand for alternative cash-management accounts. Muir’s April 2023 presentation linked Arc’s growth to the crisis and reported thousands of sign-ups. This customer demand increased the value of usable accounts and documented partner relationships.[9]
The same episode sharpened regulatory scrutiny. In July 2024, the OCC, Federal Reserve, and FDIC issued a joint statement on bank-fintech deposit arrangements.[16] The FDIC later proposed stronger beneficial-owner recordkeeping for third-party deposit accounts, explicitly addressing what happens when an intermediary fails.[15] Growth made compliance and partner reliability more valuable, not less.
Split: investor AI outgrew banking product
Arc Intelligence emerged from internal lender work and found a distinct market. Lombardo confirmed the separation in September 2025: “Arc continues to operate as Arc”.[4] The company separated it as F2 in September 2025, backed by existing investors.[14] The split narrowed Arc back toward startup cash management and gave each business its own buyer, cadence, and capital. It also removed part of the proprietary lender-workflow story from the company Axos later bought.
Exit: the product joined direct banking infrastructure
Axos said Arc contributed a team, technology platform, and expertise with innovation companies. Axos contributed banking products, nationwide distribution, capital, and direct infrastructure. Lombardo said: “We built Arc with the belief that businesses deserve a more intelligent and integrated financial platform.”[1] The buyer closed the deal thirteen days later.[2]
Arc’s April 2026 disclosures distinguish Fifth Third accounts through Stripe from investment advisory and brokerage arrangements with Arc Advisory, Atomic Brokerage, and Pershing. Securities can lose value; deposit eligibility depends on account structure and applicable requirements. The bank acquisition should not be read as proof that every account, instrument, or intermediary carries the same protection.[24]
The structural mechanism is convergence between interface and institution. Arc simplified the interface with software, then added products whose safety and economics depended on regulated partners. A bank could internalize that dependency. The acquisition may therefore complete the strategy even if the standalone product was viable. Without a purchase price or revenue data, the strength of the financial exit remains unknown.
Key Lessons
- Use a balance-sheet wedge to learn the market. Arc's first facility let it build underwriting models and customer relationships. A marketplace then kept borrower relationships while shifting funding to participating lenders.
- A crisis can reveal the real product. Arc started with financing, but the SVB failure made cash safety and diversification urgent. Cash-management volume reportedly multiplied as customers sought alternatives.
- Partner rails become more important with scale. Stripe, Fifth Third, and BNY Mellon Pershing let Arc ship banking products quickly. More deposits, products, and regulation increased the value of direct bank infrastructure.
- Separate a product when its buyer and cadence diverge. F2 served lenders and investors; Arc served startup finance teams. The spinout gave each a clearer roadmap before Axos bought the cash-management company.
- Acquisition can complete a fintech architecture. Arc brought software and startup distribution; Axos brought a chartered balance sheet and nationwide bank products. The deal joined layers that the standalone company had assembled through partners.
