Slash Raises $100M Series C at $1.4B Valuation — Teenager-Founded Ramp Competitor Adds AI Agents to Financial OS

TechCrunch·high signal

Slash, the vertical banking platform founded by teenagers, raised $100M at a $1.4B valuation led by Khosla Ventures and Ribbit Capital, announced April 16. The platform bundles business checking, corporate cards, stablecoin payments, treasury management, invoicing, multi-entity support, global USD accounts, and AI agents into a single financial operating system for online businesses. For builders: Slash is the clearest example of a next-gen fintech cannibalizing Ramp, Brex, and Mercury simultaneously by starting AI-native rather than bolting agents onto legacy infrastructure.
