Rox Raises $100 Million Series B at $1.3 Billion Valuation

Rox has raised $100 million in Series B financing at a $1.3 billion valuation, money the San Francisco startup will spend pushing AI revenue agents deeper into the world's largest companies. General Catalyst and March Capital co-led the round. Sequoia Capital and Factory returned, joined by new backers Databricks Ventures and Prosperity7 Ventures.

The check lands just months after Rox announced $50 million in seed and Series A funding in November 2024 — the same year Ishan Mukherjee, Shriram Sridharan and Diogo Ribeiro founded the company. In venture terms, Rox went from incorporation to a $1.3 billion valuation in roughly a year.

What do the numbers actually show?

Rox says annual recurring revenue grew more than tenfold during its first year in market, and enterprise net revenue retention exceeded 700%. Customers span IT services, energy, commodities, medical technology, industrial manufacturing and automotive markets.

The company also disclosed customer outcomes — and, notably, it separated qualified pipeline from closed revenue, a distinction many AI sales vendors blur. At a global IT services firm, Rox generated $330 million in qualified pipeline over eight weeks. At a medical technology company, it identified more than $200 million in funding opportunities and helped close $24 million in actual revenue over five months.

Rox additionally reported a 24.3-times return on investment within 90 days at a German engineering and technology company. What the company did not disclose: absolute revenue figures, customer counts or churn data. Pipeline numbers, however large, are not booked sales — and a tenfold increase says little without the starting base.

What is the product, and where does it run?

Rox builds agents that generate pipeline, qualify leads, book meetings, manage deals and expand customer accounts inside a customer's existing enterprise systems. The technology sits on each customer's own data warehouse rather than a proprietary data layer — a design choice that matters for large enterprises with strict governance requirements.

Manu Narayan, CIO of GitLab, said the appeal is partly procedural: "A core part of our internal AI strategy is freeing our teams from routine activities so they can spend more time on higher-value strategic work. Rox's agents help the revenue team find and research prospects, and fit into the systems and governance standards we already run."

The new capital will fund AI research, custom models and evaluation infrastructure, plus expansion across healthcare, industrial, financial services, energy and technology customers. Rox is also developing a benchmark to assess agents on real-world revenue tasks — an implicit acknowledgment that measuring AI agent performance remains unsettled ground.

The company recently cut outbound prospecting pricing by 50%, attributing the reduction to research-led improvements. A price cut that soon after a mega-round suggests Rox sees pricing power as a lever for enterprise adoption, not a sign of margin pressure — though the company offered no unit economics to support that reading.

What did the founders and investors say?

Ishan Mukherjee, co-founder and CEO, made the claim of full internal adoption: "Rox is the product I wish I had. 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. This round lets us go further in our ultimate goal of growing the world's revenue."

Sumant Mandal, co-founder and managing partner of March Capital, framed the bet in platform terms: "We're thrilled to partner with Ishan and the Rox team as they build a generational platform for revenue teams. Their rare combination of deep technical talent and real domain expertise shows up in the product, and it came through clearly in our conversations with delighted Global 2000 customers across industries."

What happens next?

Rox's stated focus is automating administrative and research-intensive sales work so human teams can concentrate on complex accounts and relationships. With $100 million fresh capital and a benchmark effort underway, the company is positioning itself as the reference standard for enterprise revenue agents — a claim the market, not the press release, will test.
