Slash raises $100 million Series C and launches AI agent to automate business finance

Slash Financial has raised $100 million in a Series C funding round, reaching a $1.4 billion valuation and officially entering unicorn status. The round was led by Ribbit Capital, with participation from existing investors including Goodwater Capital, New Enterprise Associates (NEA), and Y Combinator, alongside new investor Khosla Ventures.

With this latest raise, Slash has secured more than $160 million in total funding since its founding in 2021. The company’s valuation has scaled rapidly, rising from $370 million in its Series B round less than a year ago, reflecting strong growth momentum and investor confidence.

The funding will support what the company describes as its most significant product expansion to date, centered around the launch of its new AI-powered financial agent, Twin. Designed to function as an “AI chief of staff,” Twin leverages full contextual access to a company’s financial data within the Slash platform to automate workflows, surface insights, and execute actions such as payments, expense management, and operational tasks.

Founded by CEO Victor Cardenas and CTO Kevin Bai, Slash provides business banking infrastructure including accounts, corporate cards, payments, and treasury tools to approximately 5,000 companies. The platform has demonstrated rapid growth, surpassing $250 million in annualized revenue in 2025, representing a 2,400% increase over the previous two years.

A key driver of this expansion has been the company’s push into programmable financial infrastructure. Its Global USD Account, powered by Stripe’s Bridge, exceeded $1 billion in annualized payment volume within nine months of launch, highlighting strong adoption of stablecoin-based financial products.

The introduction of Twin builds on earlier AI initiatives, including the recent release of the Slash Model Context Protocol (MCP), which enables third-party AI agents to integrate directly with the platform’s API. Together, these developments signal a broader shift toward “agentic finance,” where intelligent systems handle financial operations autonomously rather than relying on manual workflows.

According to the company, the long-term vision is to eliminate the need for businesses to actively manage financial tools, replacing traditional interfaces with AI-driven systems capable of executing tasks and optimizing outcomes in real time.

By combining rapid product development, embedded finance, and AI-native infrastructure, Slash is positioning itself as a next-generation operating system for business finance, aligned with the growing demand for automation and intelligent financial management.
