Rox secures $100M Series B, reaching $1.3B valuation for revenue agents

Rox, an enterprise software firm creating an autonomous agent system for corporate sales departments, has secured $100 million in Series B equity financing co-led by General Catalyst and March Capital ^[0]. According to reporting on the transaction, the financing round closed on Nov. 11, 2026, establishing a post-money valuation of $1.3 billion ^[1].

A syndicate of existing and new institutional backers joined the round, including Sequoia, GV, Prosperity7, and corporate backer Databricks Ventures ^[1]. The transaction marks a step-up from earlier reporting, which pointed to an investment completed in March 2026 at an estimated valuation of approximately $1.2 billion ^[1].

Cofounders Ishan Mukherjee, Shriram Sridharan, and Diogo Ribeiro started the company in 2024 to construct a revenue engine powered by autonomous agents ^[1]. The software handles automated sales actions directly inside enterprise pipelines, seeking to streamline daily execution for commercial teams ^[1].

According to the financing announcement, Rox plans to direct the primary proceeds from the $100 million round toward three core areas: advancing its artificial intelligence research efforts, accelerating core product engineering, and growing headcount across customer-facing go-to-market divisions ^[1]. The company continues to compete in the expanding enterprise workflow category against incumbent customer relationship management providers ^[1].
