Lead
Rox raised $100M in a Series B round at a $1.3B valuation, the company announced on November 12, 2026. General Catalyst and March Capital co-led the financing. The San Francisco company builds AI agents that run parts of enterprise sales and revenue operations, a job usually split between human reps, operations staff and CRM software.
The round arrives two years after Rox's founding in 2024 and two years after it disclosed $50M in combined seed and Series A funding. The company did not disclose valuations for those earlier rounds.
Who Is Backing Rox?
Existing investors Sequoia Capital and Factory returned for the round. New backers include Databricks Ventures and Prosperity7 Ventures. The company has not disclosed how much each investor contributed or what share of the company the $100M buys.
Rox was founded by Ishan Mukherjee, who serves as CEO, along with Shriram Sridharan and Diogo Ribeiro. A General Catalyst partner said in the announcement that Rox is winning conversations against legacy systems. A Sequoia partner described the startup as a clear example of real return on investment.
What Does Rox Actually Sell?
Rox sells AI revenue agents that sit on top of a customer's existing sales data and carry out work such as finding accounts, qualifying pipeline and preparing outreach. The pitch targets the Global 2000, the largest companies by revenue, and it positions the product against Salesforce and other incumbent CRM platforms. Rox frames its software as a replacement for manual upkeep of those systems rather than a plug-in to them.
The company's own figures are large, and none have been independently verified. It says annual recurring revenue grew more than tenfold in its first year and that net revenue retention among enterprise customers exceeds 700%. It also cites a return of roughly 25x within 90 days of deployment.
Customer examples come from the same announcement. A global IT services firm reportedly generated $330M in qualified pipeline in eight weeks. A medical technology company identified more than $200M in opportunities and closed $24M in revenue. An engineering and professional services firm identified more than $310M in opportunities.
Pipeline is not revenue, and "identified" is not "closed." The $24M closed figure is the only one of the three that reflects booked business, and the company did not state the time frame or the baseline it was measured against. Absolute revenue for Rox itself was not disclosed.
Why Does a $1.3B Valuation Matter at This Stage?
A $1.3B valuation for a two-year-old company signals that investors are pricing Rox on growth rate and enterprise retention rather than on scale. The company has not disclosed its ARR, so the multiple cannot be calculated. Tenfold growth from a small base is a common feature of early enterprise software, and a retention figure above 700% usually means a small number of customers expanded sharply.
The round also reflects crowded competition. Startups such as 11x, Optivian and Airspeed target adjacent parts of sales automation, many pitching AI "digital workers" for prospecting or outbound. Rox is betting that a system tied to a company's full revenue data will beat narrower point tools. Incumbents including Salesforce have added their own agent products, so the claim that startups can displace them is still untested at Global 2000 scale.
The participation of Databricks Ventures adds a data-infrastructure angle. Enterprise agents depend on clean access to customer data, and a data platform investor has a commercial interest in how that access is built.
How Will Rox Spend the Money?
Rox plans to put the capital into AI research, custom models and evaluation infrastructure. It also intends to expand deployments across healthcare, industrial, financial services, energy and technology customers. Evaluation tooling matters because enterprise buyers need evidence that an agent's outputs are accurate before it touches customer accounts.
Headcount and hiring targets were not disclosed.
Outlook
Rox now holds $150M in total disclosed funding and a unicorn valuation within two years of founding. The next test is whether the retention and return figures hold as the customer base widens beyond early adopters. Incumbent CRM vendors and well-funded AI sales startups will contest the same budgets, and the company will need to publish revenue figures that match its valuation.
