Rox, a startup building AI agents that automate enterprise sales, has raised a $100 million Series B at a $1.3 billion valuation, the company announced on November 11. The Rox Series B was co-led by General Catalyst and March Capital, with existing investors Sequoia Capital and Factory doubling down and new investors Databricks Ventures and Prosperity7 Ventures joining.
The financing follows a $50 million seed and Series A announced in November 2024. In its first year in market, Rox says it has grown annual recurring revenue by more than 10 times and is now deployed by leading public and private enterprises in IT services, energy, commodities, medical technology, industrial manufacturing and automotive. The company reports more than 700 percent net revenue retention across enterprise customers, with some seeing about 25 times return on investment within 90 days.
What Rox Does
Rox builds a revenue agent for the Global 2000, the world’s largest companies. The agent generates pipeline, qualifies leads, books meetings, manages deals and expands accounts inside a company’s existing systems. It is built on each customer’s individual data warehouse, pulling from CRM records, email, calendars, Slack, call transcripts, documents and internet sources.
The pitch is that customer relationship software should put information to work, not just store it. Enterprise sales follows a power law, Rox said in its announcement: the top 15 percent of reps bring in roughly 90 percent of revenue, while the average rep spends 40 percent of their time on administrative work, according to Salesforce. Rox was built to raise the ceiling for those teams, automating pipeline generation, deal execution and upsells so reps can spend more time building relationships.
“Rox is the product I wish I had,” said Ishan Mukherjee, Rox co-founder and chief executive. “We built Rox for the Global 2000 because that is where the problem is the hardest and the stakes are the highest. Our own go-to-market runs entirely on Rox, with no other tools, and our customers are already generating hundreds of millions of dollars of pipeline at a fraction of the traditional cost.”

Customer Results, as Reported by Rox
Rox’s announcement is built around customer numbers the company reported itself. A global IT services firm got $330 million in qualified pipeline in eight weeks and handed pursuit preparation to Rox, getting 1,000 hours back for selling. A global medical technology company saw more than $200 million in new funding opportunities identified at medical facilities, and closed $24 million in revenue in five months. A leading global engineering and professional services firm saw more than $310 million in potential opportunities identified, including previously missed public sector bids.
Other examples include a DevSecOps platform that doubled outbound volume, a payroll provider that autonomously found and engaged 4 million prospects at 20 percent of the cost of traditional outreach, an industrial software company that doubled sales team capacity and booked more than 50 meetings in six weeks, and a large German engineering and technology company that saw 24.3 times return on investment in 90 days.

Why Investors Are Betting on Revenue Agents
Revenue is the next frontier for AI agents and one of the hardest, Rox said. Unlike code, where an agent can test its work immediately, sales outcomes take weeks or months to materialize. Rox is tackling that with custom models and original research, including a revenue agent benchmark to measure performance on real world revenue tasks. The company recently cut outbound prospecting pricing by 50 percent, driven by research led improvements.
“There is a long graveyard of companies that said they’d take on Salesforce,” said Marc Bhargava, managing director at General Catalyst. “The difference now is that the old systems were never built for agents, and boards are finally willing to start fresh. Rox is winning those conversations. That’s why we doubled down.”
Konstantine Buhler, a partner at Sequoia Capital, called Rox “a clear example of the real ROI of AI, delivering measurable results for Global 2000 sales teams and CROs in under a quarter.” Rox was also named a Visionary in the 2026 Gartner Magic Quadrant for Revenue Action Orchestration and a Major Player in the 2026 IDC MarketScape for Worldwide Unified Revenue Orchestration Platforms.
What the Money Is For
Rox will use the capital to advance its AI research, custom models and evaluation infrastructure, and expand its work with large enterprises across healthcare, industrial, financial services, energy and technology. Fortune reported that the company plans to expand its United States sales, marketing and commercial team fivefold next year.
Rox was founded in 2024 by Mukherjee, Shriram Sridharan and Diogo Ribeiro, and is headquartered in San Francisco. Its customers include Puma, Groq and Ramp, according to Reuters, and MongoDB, New Relic and Trafigura, according to Fortune. GitLab chief information officer Manu Narayan said Rox’s agents “help the revenue team find and research prospects, and fit into the systems and governance standards we already run.”
Why It Matters
The round puts Rox among the best funded challengers in a race to rebuild enterprise software around agents rather than databases. Salesforce generated $41.5 billion in revenue for fiscal 2026 and says it has worked with more than 150,000 companies, so Rox is taking on an entrenched incumbent. But the bet from General Catalyst, March Capital, Sequoia and Databricks Ventures is that boards are now willing to replace the system of record itself, not just add AI on top of it. Whether Rox’s customer numbers hold up at larger scale is the question the next year will answer.
