Analysis
As of November 11, 2026, Rox, the AI sales-agent startup, has raised $100 million in Series B funding at a $1.3 billion valuation, the company told Fortune in an exclusive. General Catalyst and March Capital co-led the round, Sequoia and GV returned, and Prosperity7 joined as a new investor.
Fortune framed the raise as a direct challenge to Salesforce, a company it puts at a $172 billion market cap.
The round makes Rox a unicorn-valued company in AI applications for revenue teams, and it lands in a week when private AI marks are being set against a very loud public backdrop: Pulse has covered Path Robotics, Sand.ai and Mercor rounds in the past two days, and our funding tracker keeps the running list.
“Fortune framed the raise as a direct challenge to Salesforce, a company it puts at a $172 billion market cap.”
What does Rox do?
Rox sells AI agents to sales teams. Per Fortune, "AI agents research customer accounts, recommend who to prioritize, and prepare outreach for clients." When General Catalyst announced its first investment in November 2024, it described the company as "building a new revenue operating system for the applied AI era" (General Catalyst).
Rox's early customers named by Fortune include Ramp, New Relic, Trafigura, MongoDB and Groq. The company says its annual recurring revenue grew more than tenfold since its first year after launch; it did not give Fortune a dollar ARR figure. Dealroom's March report carried an $8M ARR figure that neither company confirmed.
Who founded Rox?
CEO Ishan Mukherjee co-founded Rox. Before it, he started Pixie Labs, which New Relic acquired for roughly $150 million in 2020, per Fortune, and he was a product lead on Apple's Siri Knowledge Graph. His co-founders include Shriram Sridharan, a founding member of AWS's Amazon Aurora database team, former Google employee Diogo Ribeiro and Stanford AI Lab professor Christopher Ré. Sequoia's partnership note also credits Avanika Narayan alongside Ré for research in data preparation with AI (Sequoia). Dealroom lists the company as founded in 2024.
How much has Rox raised?
Before this round, Rox "previously raised $50M across a Sequoia-led seed and a General Catalyst-led Series A announced in November 2024," per Dealroom. Sequoia said it led the seed with participation from GV and General Catalyst.
In March 2026, Dealroom, citing TechCrunch's sources, reported a new General Catalyst-led round valuing Rox at $1.2B; Dealroom noted that neither company confirmed it, and no amount was given.
Disclosed funding is therefore at least $150 million on a Pulse desk sum of the $50 million and the $100 million.
Value Add VC data
- Nov 2024, seed + Series A -- $50M combined, valuation not disclosed, seed led by Sequoia and Series A led by General Catalyst (Dealroom)
- Nov 2026, Series B -- $100M at $1.3B, co-led by General Catalyst and March Capital (Fortune)
- Mar 2026, unconfirmed round -- amount not disclosed, at a reported $1.2B, led by General Catalyst per TechCrunch's sources (Dealroom)
If the March mark holds, the Series B is a modest step-up of about 8% from $1.2B to $1.3B, not a fresh unicorn jump. Comparable: Mercor's $750M Series D at $20B this week, another AI company with General Catalyst on its cap table.
Rox competitors: Salesforce and ServiceNow
The incumbents are enormous. Salesforce generated $41.5 billion in revenue for fiscal 2026 and says it has worked with more than 150,000 companies, Fortune reported. ServiceNow ended its latest quarter with 680 customers paying more than $5 million each, per the same Fortune report. Rox's bet is that the system of record matters less once agents do the research and outreach a rep used to log by hand.
The risk is plain: Salesforce owns the data layer Rox's agents need, and incumbents ship agents too. Rox has not confirmed a revenue figure, headcount or a customer count, and a tenfold multiple off an undisclosed first-year base can describe a small business. A $1.3 billion price on that disclosure set is a growth bet, not a revenue multiple anyone outside the cap table can check.
The next proof point is a named dollar ARR figure or a customer that replaces, rather than sits on top of, its Salesforce instance.
