Slash Achieves Unicorn Status Following $100m Series C Fundraise

WHY THIS MATTERS: The $100 million capital injection validating Slash as a unicorn is less about the headline figure and more about the strategic direction it greenlights for the entire B2B financial technology sector. This is a definitive pivot toward the era of AI agents and autonomous finance. The launch of ‘Twin,’ a dedicated financial AI Chief of Staff, transforms the core value proposition of a business banking platform from merely providing a superior digital interface to offering genuine operational automation. By offloading complex workflows—from invoice generation to real-time payments—to an intelligent agent, Slash is fundamentally enabling what investors are calling a “lean, high-velocity” model for modern businesses. This development signals that the next competitive battleground is no longer feature parity in corporate cards or expense management, but the depth and security of embedded, proactive AI that minimizes human effort. This move sets a new bar for what a truly indispensable financial operating system must deliver.

Slash Financial, Inc., the banking platform¹ built for modern businesses, is now valued at $1.4 billion following a $100m Series C funding round led by Ribbit Capital. New investor Khosla Ventures and Goodwater Capital, who led Slash’s Series B just 16 months ago, co-led the round. This latest funding elevates Slash to unicorn status and brings the total amount of capital raised to more than $160 million. New Enterprise Associates and Y Combinator also participated in the round and are investing in Slash for a fourth time. 

“We went from $10 million to $250 million in annualized revenue in 24 months,” said Victor Cardenas, CEO and co-founder, Slash Financial. “This round lets us build the next layer of what Slash can do: more industries, more markets, more of the financial tools businesses actually need. The support from Ribbit, Khosla, and Goodwater is invaluable and will enable us to build what’s next, faster.”

 The nine-figure fundraise comes amid a period of rapid growth for Slash. The company surpassed $250 million in annualized revenue in 2025 and exceeded $1 billion in annualized stablecoin payment volume within nine months of launching the product. 

“What drew us to Slash was the speed and conviction we saw from Victor, Kevin and the team,” said Micky Malka, founder of Ribbit Capital. “The ratio of output to headcount is something we’re only starting to see from the best AI-native companies. They’re building the bank of the future, where agents handle the processes that used to require entire departments. We couldn’t be more excited to partner with them.”

Since its founding in 2021, Slash has grown from an early-stage startup into a multi-product business banking platform, now powering more than $30 billion in annualized payment volume and serving more than 5,000 businesses across a growing range of industries. 

“Slash is building the financial operating system for a new class of business: lean, high-velocity operators who will move more money with fewer people than anyone thought possible,” said Jai Sajnani, Partner at Khosla Ventures. “What excites us is the underlying model: go deep in one industry, earn the right to expand, repeat. Slash is on its way to becoming an indispensable platform for operators building with AI.”

“AI is enabling a new generation of SMBs and solo entrepreneurs to operate at unprecedented scale,” added Eric Kim, Co-Founder and Managing Partner of Goodwater Capital. “That shift demands a modern financial stack built for how they actually work. Slash is building the Finance Operating System to meet this unique moment, bringing banking, payments, and software into a single platform. We’re excited to co-lead their Series C.”

To date, Slash has raised a total of $160 million. Just last year, the company raised $41 million at a $370 million valuation during its Series B funding round, led by Goodwater Capital, NEA, and Menlo Ventures. In 2023, Slash secured $19 million in its Seed and Series A rounds, which included a commitment from Rick Yang at New Enterprise Associates (NEA), with additional participation from Y Combinator, Menlo Ventures, Connect Ventures, Soma Capital, Tinder co-founder and former CMO Justin Mateen, Plaid co-founder William Hockey, and other angels and funds.

AI agents define the start of Slash’s new chapter

With the Series C, Slash is making its most significant product investment to date, one that extends the platform both deeper and wider. Twin, Slash’s new AI-powered financial agent, brings a new level of intelligence and automation to the financial workflows of existing Slash customers.

Twin acts as an AI Chief of Staff by leveraging contextual access to a company’s entire Slash account to surface insights on recurring financial or operational tasks, and take real action via direct card or bank payments and other key functions. 

Twin represents a fundamental shift in how businesses interact with their finances. Rather than logging into a dashboard to manually execute transactions, Slash account holders can now direct Twin to handle any action available within the platform, from payments and invoice generation to spinning up new cards, all informed by real-time data across their accounts, card spend, treasury, virtual accounts, and reimbursements. The underlying premise is that businesses shouldn’t have to operate their financial tools manually if an intelligent agent can do it for them. All activity runs through a secure agent layer that keeps sensitive account and card details protected.

FF NEWS TAKE:Yes, this move absolutely shifts the industry’s focus. The combination of rapid revenue scaling, massive transaction volume, and a commitment to AI-native workflow automation proves the verticalised, agent-based approach is working. We should immediately watch how direct competitors, particularly those in the SMB banking and expense management space, respond to this AI-driven pressure. The race is now on to see who can transition fastest from a software-first platform to an intelligence-first platform.
