Overview
Fundbox is a San Francisco-based financial technology company founded in 2013 by Israeli entrepreneurs Eyal Shinar, Yuval Ariav and Tomer Michaeli, with its development center in Tel Aviv (Haaretz). It began as a direct lender advancing payment on small businesses’ unpaid invoices, reached a $1.1 billion valuation with a $100 million Series D in November 2021 — and then spent the following years rebuilding itself into something different: embedded capital infrastructure, credit delivered inside the software platforms small businesses already use (TechCrunch; PYMNTS).
Invoice financing, Israeli-founded
Shinar had been a partner at the venture firm Battery Ventures before founding Fundbox (Haaretz). The original product was invoice financing with an algorithmic twist: beginning in August 2013, Fundbox offered credit lines to small businesses based on their receivables, charging a computer-generated commission calibrated to the risk of each cash advance (Haaretz). The model attracted notable early backers: a $50 million round in September 2015 led by Spark Growth Capital brought in Ashton Kutcher, Jeff Bezos’ Bezos Expeditions and talent manager Guy Oseary, following a $40 million round that March and taking total investment to $107.5 million (Haaretz).
The unicorn round and the AI underwriting story
The November 2021 Series D — $100 million led by the Healthcare of Ontario Pension Plan — valued Fundbox at $1.1 billion and brought total equity raised to $410 million since 2013 (TechCrunch). CEO Prashant Fuloria told TechCrunch the company, boosted by pandemic-era demand, had crossed a $100 million annual revenue run rate — “well and truly beyond” that, though not yet profitable — had tripled its new-customer acquisition rate in 2021, and had connected with over 325,000 small businesses while transacting more than $2.5 billion in working capital (TechCrunch).
The company’s differentiator, Fuloria said, was its focus on business-to-business SMBs — suppliers invoicing clients like restaurants and waiting to be paid — combined with an AI-driven underwriting model that mapped what he called a “business graph”: businesses as nodes, their transactions as connections, generating risk signals for each B2B transaction (TechCrunch). More than 99 percent of credit decisions were fully automated, he said, and the company offered lines of credit up to $150,000 (TechCrunch). Around the same time Fundbox expanded beyond lending into payments and membership offerings, launching Flex Pay to give business owners more ways to fund expenses (TechCrunch).
The embedded-capital pivot
The pivot’s clearest public marker came in May 2022, when Visa announced a partnership with Fundbox to strengthen what it already called an “embedded working capital platform” (IBS Intelligence). The first product was the Fundbox Flex Visa Debit Card, issued by Pathward, N.A., bringing Flex Pay’s spend-management to card-accepting merchants; the companies also planned small-business buy-now-pay-later products and instant fund disbursement via Visa Direct (IBS Intelligence). Fundbox reported Flex Pay payment volume growing more than 80 percent quarter-over-quarter and said its annual revenue run-rate had passed $160 million (IBS Intelligence).
The embedded strategy deepened in the following years. By mid-2025 Fundbox’s credit was being embedded through partners including Autobooks (Autobooks Capital), Cantaloupe (Cantaloupe Capital) and Nav, which presented Fundbox’s pre-approved offers to its own SMB users (PYMNTS). On June 23, 2025, the founding team of embedded-lending platform Vaya Technologies — co-founders Ankit Singh and Soham Sen — joined Fundbox in product and engineering leadership roles to accelerate the development of new embedded credit products, a move the company framed as strengthening its embedded-fintech and vertical-SaaS expertise (PYMNTS).
What this profile does not claim

- A reported February 2026 credit-facility renewal with ATLAS SP Partners and Blue Owl funds appears only in company announcements and trade listings, not in fully-read independent coverage — it is not asserted as fact.

- Partnership claims beyond those independently reported (Visa, Autobooks, Cantaloupe, Nav) — including names appearing only in company boilerplate — are not asserted, and no internal links were built on them.
- Customer counts, origination volumes and automation rates are company-reported via press coverage and are presented as reported, not as independently audited facts.
