What Rox builds for enterprise sales teams
Rox makes AI agents that handle sales work inside a company’s existing systems. The agents generate leads, book meetings, manage deals and expand accounts with current customers.
The software targets Global 2000 companies. It runs on each customer’s own data warehouse instead of storing account data in a separate CRM.
Rox launched a public beta in late 2024 and came out of beta in September 2025. During the beta, more than 35 enterprise sales teams used the product, including MongoDB, Confluent and Ramp, according to General Catalyst.
Fortune framed the round as a challenge to Salesforce. Ishan Mukherjee, Rox’s co-founder and CEO, has argued that legacy CRM platforms are exposed as enterprises move their data to modern warehouses.
Rox funding history and valuation
Rox came out of stealth in November 2024 with $50 million. Sequoia led the seed round with GV participating, and General Catalyst led the Series A. The company did not share a valuation at the time.
In March 2026, TechCrunch reported that Rox had raised a General Catalyst-led round at a $1.2 billion valuation, citing unnamed sources. Neither company confirmed that report or gave an amount.
The new Series B brings disclosed funding to about $150 million. At $1.3 billion, the valuation is roughly 8.7 times the capital Rox has disclosed.
Rox has not disclosed revenue. It says its annual recurring revenue grew more than 10 times in its first year on the market. Sources told TechCrunch in March that Rox was projected to finish 2025 with about $8 million in ARR, a figure the company did not confirm.
How Rox will use the new funding
Mukherjee said the money will go toward AI research and product development. Rox also plans to grow its US sales, marketing and commerce teams fivefold next year.
The research work includes building custom models alongside the agent software, according to Unite.AI’s coverage of the round.
Who founded Rox
Ishan Mukherjee co-founded Pixie Labs, a software monitoring startup that New Relic bought in 2020. He then served as New Relic’s chief growth officer before starting Rox in 2024.
Rox’s other co-founders are Shriram Sridharan (CTO), Diogo Ribeiro (chief growth officer) and Christopher Ré, who leads research.
Rox and the AI sales agent market
Rox competes with several venture-backed sales automation startups. 11x reached a $350 million valuation after a $50 million Series B in 2025, and Artisan raised a $25 million Series A in April 2025.
Agent companies across many functions have raised large rounds this year. Our list of the top-funded AI agent startups tracks where the biggest checks have gone.
The Rox round came during a busy stretch for AI deals. In late October, startups announced about $5.18 billion in a single week, as covered in our Oct 19 to 25 funding roundup.
