## Summary

API-first corporate card and global payments platform for high-spending businesses; $60.1M raised with $41M Series B, $3B annualized volume in 2025 competing with Brex and Ramp for programmable spend management.

## Company Overview

Slash is a Los Altos-based fintech company providing comprehensive financial services and corporate cards for high-spending businesses — offering global payments, programmable corporate cards, real-time payment rails, spend management APIs, reconciliation, and detailed reporting that financial operations teams at high-growth companies and high-volume businesses need to manage complex payment workflows. A Y Combinator W21 graduate, Slash raised $60.1 million total including a $41 million Series B in May 2025 led by Goodwater Capital with New Enterprise Associates and Menlo Ventures participation, surpassing $3 billion in annualized volume in 2025 (up from $1 billion in 2024).

Slash's platform is differentiated by its programmable API layer: rather than fixed expense policies, Slash allows finance teams to write rules that govern card behavior in real-time — a card that automatically approves software vendor charges under $500, requires manager approval for travel above $2,000, and blocks any merchant outside an approved category list. This programmatic control creates precise spend governance without requiring manual approval workflows for every transaction. The global payments infrastructure handles multi-currency vendor payments across 100+ countries.

In 2025, Slash competes in the corporate card and spend management market with Brex (corporate cards and banking for startups), Ramp (expense management and corporate cards), Airbase (procurement and AP), and Mercury (banking and cards for startups) for high-growth company financial infrastructure. The $3B annualized volume growth in 2025 (3x year-over-year) signals strong market momentum. Slash's differentiation from Brex and Ramp centers on the API-first programmability for technically sophisticated finance teams and the high-volume payment infrastructure for businesses with complex transaction patterns. The 2025 strategy focuses on growing the high-spending business customer base, deepening the API integrations with ERP and accounting systems, and expanding the global payments coverage.
