Rox raises $100M at $1.3B valuation to take on Salesforce

Rox, an AI sales startup that has been around for barely two years, just raised $100 million in Series B funding at a $1.3 billion valuation. Its pitch is aimed squarely at the enterprise software establishment, Salesforce included.

Cofounder Ishan Mukherjee is betting that the systems running the world’s biggest sales teams won’t need the old guard forever.

Who wrote the checks

General Catalyst and March Capital co-led the round, according to Fortune, which first reported the deal. Sequoia and GV returned from earlier rounds. Prosperity7 came in as a new investor.

Research compiled on the deal also lists Databricks Ventures among the new participants. The $1.3 billion figure is a post-money valuation, meaning it includes the fresh $100 million. The round reportedly closed on November 11, 2026.

The cap table has a familiar look. Sequoia led Rox’s seed round, and General Catalyst led its Series A. Together those early rounds totaled $50 million, announced in November 2024.

There is one wrinkle. A separate round at a valuation of roughly $1.2 billion was reported in March 2026. If both figures hold, the step-up from $1.2 billion to $1.3 billion is real but modest.

What Rox actually does

Rox calls itself an AI-native revenue operating system. Its approach is to hand that grunt work to swarms of autonomous AI agents. Those agents plug into the software companies already run, including Salesforce and Zendesk. The goal is to free reps to concentrate on deals rather than data entry.

The early numbers explain why investors are leaning in. Rox grew annual recurring revenue (ARR) more than 10x in its first year. Its net revenue retention topped 700%.

One customer reportedly generated $330 million in qualified sales pipeline in eight weeks. Some customers have reported roughly 25x return on investment within 90 days.

The customer list mixes tech names with industrial ones. It includes Ramp, MongoDB, New Relic, Trafigura and Groq, spanning sectors from IT services to automotive.

The team and the backstory

Rox was founded in 2024 by Ishan Mukherjee, Shriram Sridharan and Diogo Ribeiro. The trio brings backgrounds from major tech companies, including New Relic, which now also appears on the customer roster.

Rox says the new capital will go toward AI research, product development and its go-to-market teams. It aims to expand those teams fivefold over the next year.
