Rox Raises $100 Million at $1.3 Billion Valuation to Attack Salesforce

Rox has raised $100 million in Series B funding at a $1.3 billion valuation, money the startup will spend building AI agents it says can replace Salesforce rather than merely sit beside it. General Catalyst and March Capital co-led the round, the company told Fortune in an exclusive published Wednesday. Sequoia and GV returned; Prosperity7, the venture arm tied to Saudi Aramco, joined as a new investor.

The San Francisco-based company builds AI agents for sales teams. The agents research customer accounts, rank which ones deserve attention and draft the outreach. The pitch is blunt: the CRM should do the work, not just store records of work done elsewhere. Rox named Ramp, New Relic, Trafigura, MongoDB, Groq and America's Auto Auction among its early customers.

Who is behind Rox?

Cofounder and CEO Ishan Mukherjee has sold a company before. New Relic bought his previous startup, Pixie Labs, for roughly $150 million in 2020, and he then served as New Relic's chief growth officer. He isn't alone. Shriram Sridharan was a founding member of the AWS team that built the Aurora database. Diogo Ribeiro came from Google. Christopher Ré, a Stanford AI Lab professor, cofounds too and gives the outfit research depth that most sales-software shops can't match.

What does the money say about the revenue?

Rox says annual recurring revenue has grown more than tenfold since its first year after launch. It did not give a dollar figure — and the outside numbers are small. TechCrunch reported in March, citing people familiar with the deal, that an earlier General Catalyst-led round valued Rox at $1.2 billion and that the company was projected to finish 2025 with about $8 million of ARR. Rox declined to comment at the time.

That would make the new $1.3 billion valuation roughly 160 times projected ARR. The multiple makes sense only if the agents eat a real slice of enterprise software spending. The fresh capital funds AI research, product development, and a plan to grow the U.S. sales, marketing and commercial team fivefold next year. Rox had earlier raised $50 million in seed and Series A funding from Sequoia, General Catalyst and GV, announced in November 2024.

Why bet against Salesforce now?

Mukherjee's argument rests on a shift already underway. Large customers, he said, have moved their data out of Salesforce and into their own environments — a migration he credits to companies such as Nvidia and Intel — and that exodus has weakened the incumbent's grip. "There are going to be autonomous agents that do customer-facing commercial work across large parts of the economy, not just tech companies," he told Fortune.

The scale gap is enormous. Salesforce reported $41.5 billion of revenue for fiscal 2026 and says it has worked with more than 150,000 companies. General Catalyst partner Marc Bhargava, who wrote Rox a check in 2024 before the company had a product or revenue, is candid about the history here. He acknowledged "a graveyard of companies" that tried to unseat Salesforce, ServiceNow or Workday. His counter: AI-native products built on a fresh code base work better than retrofits.

Wall Street shares some of that nervousness. Investor worry that AI agents will erode seat-based software pricing knocked software stocks at points this year — a slide Fortune noted was dubbed the "SaaSpocalypse." If agents do the selling, the logic runs, companies stop paying per human seat.

What happens next?

Rox now has the cash and the mandate to hire aggressively, and its tenfold ARR claim — whatever the undisclosed base — will face its first real test as the fivefold team expansion puts the product in front of far more enterprise buyers next year.
