November 11, 2026 — Rox, a San Francisco startup building AI agents for enterprise sales teams, said on Wednesday it has raised $100 million in a Series B round that values the company at $1.3 billion. Why it matters: sales is one of the biggest budgets in any large company, and Rox is now a unicorn on the claim that agents — not another dashboard — should do the repetitive revenue work.
What happened
Rox announced the $100 million Series B on November 11, 2026. The round was co-led by General Catalyst and March Capital. Existing investors Sequoia Capital and Factory increased their stakes, and Databricks Ventures and Prosperity7 Ventures joined as new investors. The raise follows the $50 million in seed and Series A funding Rox announced in November 2024.
Rox was founded in 2024 by Ishan Mukherjee, Shriram Sridharan and Diogo Ribeiro, and is headquartered in San Francisco.
What Rox actually sells
Rox describes its product as a revenue agent for the Global 2000 — the world’s largest companies. The agent works inside the systems a sales team already uses and takes on pipeline generation, lead qualification, meeting booking, deal management and account expansion. The system is built on each customer’s own data warehouse rather than a shared pool of data.
The company’s pitch leans on a familiar statistic: a small share of top sales reps produces most of the revenue, while the average rep spends a large share of the week on administrative work. Rox’s bet is that agents can absorb that admin layer and let reps spend their time on customers.
The numbers Rox is reporting
Rox says its annual recurring revenue grew more than tenfold in its first year in the market, and that it is now deployed at large companies in IT services, energy, commodities, medical technology, industrial manufacturing and automotive. It reports net revenue retention above 700% across enterprise customers and says some customers saw roughly 25x return on investment within 90 days. Named customers include Puma Energy, Groq and Ramp.
Those growth and return figures are company-reported and have not been independently audited — treat them as the company’s own account of its traction, not verified results. Rox says the new capital will go to AI research, custom models and evaluation infrastructure, including a benchmark for revenue agents, and to expanding its enterprise customer base across healthcare, industrial, financial services, energy and technology.
Why it matters
Most AI agent funding so far has chased coding and customer support, where results are easy to measure. Revenue work is harder: a sales outcome can take months to land, so an agent cannot quickly test whether it did a good job. A $1.3 billion valuation says investors think that harder problem is worth more — and that incumbents built before agents existed are vulnerable. For sales teams, the practical test is simpler: does the agent produce pipeline your reps would not have found, at a cost below the outreach it replaces? Rox now has $150 million in total reported funding to prove its answer at Global 2000 scale.
