Rox Raises $100 Million at $1.3 Billion to Put AI Revenue Agents on Top of the Corporate Data Warehouse

Rox, a San Francisco startup that builds AI revenue agents for the world's largest companies, has raised a $100 million Series B at a $1.3 billion valuation. General Catalyst and March Capital co-led the round; existing backers Sequoia Capital and Factory doubled down, GV remained on the cap table, and Databricks Ventures and Prosperity7 Ventures joined as new investors. The round comes about a year after the company announced $50 million across its seed and Series A.

The product idea is deceptively simple: instead of layering agents on top of a CRM, Rox builds them directly on each customer's own data warehouse. The agents watch accounts, spot openings, generate pipeline, qualify leads, book meetings and manage deal follow-up inside existing systems. Chief executive Ishan Mukherjee, who co-founded the company in 2024 with Shriram Sridharan and Diogo Ribeiro, frames this as a structural critique of incumbent sales software — the old systems, he argues, were never designed for agents, and if an agent reads the warehouse directly, the CRM becomes just another table in it.

The company's numbers, which come from Rox itself and have not been independently audited, are aggressive: annual recurring revenue up more than 10x in its first year in market, and net revenue retention above 700% across enterprise customers. Case studies cited in the announcement include a global IT services firm that says it gained $330 million in qualified pipeline in eight weeks while freeing about 1,000 rep-hours, a medical technology company that found more than $200 million in new funding opportunities and closed $24 million in five months, and a German engineering firm reporting a 24.3x return on investment within 90 days.

Rox anchors the pitch in a familiar industry statistic it attributes to Salesforce: the top 15% of sales representatives bring in roughly 90% of revenue, while the average rep spends 40% of their time on administrative work. The company recently cut its outbound prospecting pricing by 50%, which it attributes to research-led efficiency gains rather than discounting. It has also been named a Visionary in the 2026 Gartner Magic Quadrant for revenue action orchestration.

Revenue is a harder automation target than code: an agent can run tests against software in seconds, but sales outcomes take weeks or months to confirm, which makes the feedback loop for training and proving revenue agents slow and expensive. That is the bet General Catalyst's Marc Bhargava is making explicit — boards, he says, are for the first time telling revenue leaders to try something new rather than auto-renew the incumbent. Whether Rox's retention numbers survive a thousand customers instead of a dozen will be the real test of the category.
