Slash Raises $100M Series C, Hits $1.4B Valuation and Launches AI Agent Twin

Slash closed a $100 million Series C round, pushing its valuation to $1.4 billion and reporting $300 million in annualized revenue while unveiling an AI agent called Twin that automates invoicing, payments, and anomaly detection.

Slash, founded in 2019 by Victor Cardenas and Kevin Bai, provides a unified platform for corporate banking, cards, payments, and analytics. The company serves thousands of businesses across e‑commerce, crypto, and professional services, aiming to replace legacy expense‑management tools with a digital‑first stack.

The Series C funding totals $100 million, bringing the post‑money valuation to $1.4 billion. Slash reports annualized revenue of approximately $300 million. Its new product, Twin, is an AI agent that can autonomously generate invoices, execute payments, and flag anomalous transactions for review.

The capital will be used to expand product development, scale sales teams, and deepen integrations with banking and crypto networks. Twin positions Slash within the emerging category of agentic finance tools, where software performs routine financial tasks without human intervention. Observers note the company’s high revenue‑per‑employee ratio and its blend of traditional rails with native crypto support as differentiators.

Watch for how Twin’s adoption affects customer acquisition costs and whether competitors accelerate their own AI‑driven automation in corporate finance.
