AI sales startup Rox has secured $100 million in a Series B funding round, reaching a post-money valuation of $1.3 billion. The deal, which closed on November 11, 2026, was co-led by General Catalyst and March Capital. Existing investors Sequoia and GV participated, alongside new backers including Prosperity7 and Databricks Ventures.
The company, founded in 2024 by Ishan Mukherjee, Shriram Sridharan, and Diogo Ribeiro, previously raised $50 million in seed and Series A rounds by November 2024. Reports indicate a prior valuation of approximately $1.2 billion in March 2026. Rox operates as an AI-native revenue system that utilizes autonomous agents to integrate with existing software like Salesforce.
Rox reports that its annual recurring revenue grew more than 10x in its first year, with net revenue retention exceeding 700%. Customer success metrics include one client generating $330 million in qualified sales pipeline within eight weeks and others reporting a 25x return on investment over 90 days. The client list includes Ramp, MongoDB, New Relic, Trafigura, and Groq.
The startup plans to allocate the new capital toward AI research, product development, and the expansion of its go-to-market teams. The company intends to increase the size of these teams fivefold over the next year.
