Rox AI Hits $1.2B Valuation — General Catalyst-Backed Sales Agent Startup Reaches Unicorn as SDR Teams Face Replacement

TechCrunch·medium signal

Rox, which deploys autonomous AI sales agents to replace SDR and BDR functions, raised a new round at $1.2B valuation led by returning backer General Catalyst, per TechCrunch on March 12. The raise comes amid a record pace of $100M+ AI agent rounds in March 2026 — more than any comparable period in venture history. Rox joins Lightfield (AI-native CRM at $40M) and others targeting the $50B+ sales automation market where incumbents like Outreach and Apollo face displacement by agents that execute entire outbound sequences autonomously rather than providing dashboards for humans to operate.
