San Francisco-based Rox raised a $100 million Series B at a $1.3 billion valuation this week, co-led by General Catalyst and March Capital, with Databricks Ventures joining as a new strategic investor. The company, which builds an AI revenue agent for Global 2000 sales teams, announced the round on 11 November and followed two days later with details of the Databricks investment and partnership.
Who put in the money
General Catalyst and March Capital co-led the Series B. Existing investors Sequoia Capital and Factory doubled down, according to the company, and new investors in the round include Databricks Ventures and Prosperity7 Ventures. GV also appears among the company’s listed backers. The raise follows $50 million in seed and Series A funding that Rox announced in November 2024; the company has not disclosed a valuation for that earlier financing.
General Catalyst framed the round as a bet on timing rather than on product alone. The firm said boards are, for the first time, telling revenue leaders to try something new rather than renew the incumbent, and noted that there is “a long graveyard of companies that said they’d take on Salesforce” — the difference, in its telling, being that older systems were never built for agents. Fortune used the same competitive framing in its coverage of the round, describing Rox as betting it can take on Salesforce.
What Rox is building
Founded in 2024, Rox sells an AI revenue agent that handles pipeline generation, lead qualification, meeting booking, deal management and upsell and churn work for enterprise sales teams. The system is built on each customer’s own data warehouse rather than on a separate vendor-hosted system of record, which is the architectural argument underpinning the pitch against legacy CRM.
The company says ARR grew more than 10x in its first year in market. Its 13 November announcement reports 702% net revenue retention across strategic and enterprise customers, and the 11 November release says some customers see roughly 25x return on investment within 90 days. Those are company figures. Rox names WSP, Groq, America’s Auto Auction, MongoDB and Puma Energy among its customers, and GitLab appears in the Series B release. Rox was 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.
The new capital goes toward AI research, custom models and evaluation infrastructure, and expanded work with large enterprises across healthcare, industrial, financial services, energy and technology.
The Databricks tie-up
The 13 November announcement confirmed that Databricks Ventures invested as part of the same $100 million Series B. Alongside the investment, Databricks has validated Rox as a “Built-On Databricks” partner, which the two companies describe as recognition of Rox’s architecture for building customer-facing AI applications and agents on the Databricks Data + AI Platform. Rox describes itself as a Databricks customer and says its agent operates against customer data held in the Databricks lakehouse, using OpenSharing and Unity Catalog under the customer’s existing access controls.
Rox also says that, as an early Databricks Marketplace partner, customers can apply their Rox investment toward an existing Databricks commitment — framing that it describes as simplifying procurement. On the company’s own account, the partnership is as much commercial as technical, since it ties the agent to a data platform decision enterprises have usually already made.
What the raise means for vendors
The structure of the round is the part worth noting: a data platform’s venture arm investing in an application that runs directly on its customers’ lakehouse data, with the partnership announced alongside the money. In the same week, Growth List covered LangChain’s $300 million Series C, another agent-infrastructure raise, and Mercor’s $750 million Series D, a round that included Salesforce.
For sellers of data, CRM adjacencies and revenue tooling, the practical signal is where the buying conversation now sits: Rox is pitching Global 2000 revenue teams on agents that work inside the customer’s existing warehouse and governance model.
