Sales automation startup Rox AI reaches $1.2B valuation, sources say

Rox, a startup building autonomous AI agents to improve sales productivity, has raised a new funding round that values the company at $1.2 billion, according to multiple sources familiar with the matter.

The financing included a lead investment from existing backer General Catalyst, two of those people said. At the time the round closed last year, Rox was projected to finish 2025 with $8 million in annual recurring revenue, or ARR, according to two people familiar with the deal.

Back in November 2024, Rox said it had raised a total of $50 million, including a seed round led by Sequoia and a Series A round led by General Catalyst, with participation from GV.

Rox was founded in 2024 by Ishan Mukherjee, the former chief growth officer at New Relic. Mukherjee joined New Relic after the company acquired Pixie, a software monitoring startup he had co-founded, in 2020.

The startup describes itself as an intelligent revenue operating system that connects with a company’s existing software stack — from Salesforce to Zendesk — and deploys hundreds of AI agents. Those agents are designed to monitor current accounts, research potential customers, and update CRM systems. By bringing all of those tasks together, Rox is trying to replace and simplify the many fragmented software tools that sales teams currently rely on.

“Rox’s unique system of AI agents levels up the CRM experience,” GV investor Dave Munichiello wrote in a 2024 blog post announcing the Series A round. “These agents work constantly behind the scenes to monitor customer activity, identify potential risks and opportunities, and even suggest the best course of action.”

Rox is entering a highly competitive market spanning several categories, including established revenue intelligence companies such as Gong and Clari, as well as AI sales development platforms like 11x and Artisan. The space is also seeing a steady wave of newer AI-native, all-in-one CRM challengers, including Monaco — a startup founded by Sam Blond, the former president of corporate spending platform Brex — which emerged from stealth last month.

According to Rox’s website, the company’s customers include Ramp, MongoDB, and New Relic.
