Rox Raises $100 Million Series B at $1.3 Billion Valuation to Challenge Salesforce with AI Agents

Rox has raised $100 million in Series B funding at a $1.3 billion valuation, as the AI sales startup expands its efforts to transform how businesses manage customer relationships and sales operations.

The round was co-led by General Catalyst and March Capital, with participation from returning investors Sequoia and GV, alongside new investor Prosperity7.

The San Francisco-based company develops AI agents designed to automate sales workflows, including researching customer accounts, identifying promising opportunities and preparing outreach. Its approach aims to move beyond traditional customer relationship management (CRM) software by making AI agents actively perform sales-related tasks rather than simply storing customer records.

According to the company, its annual recurring revenue (ARR) has grown more than tenfold since its first year after launch. Rox did not disclose an exact revenue figure.

The new funding will support AI research and product development, while the company plans to expand its US sales, marketing and commercial teams fivefold in 2027.

Rox Founders and Leadership

Rox was co-founded by Ishan Mukherjee, Shriram Sridharan, Diogo Ribeiro and Christopher Ré.

Ishan Mukherjee serves as the company's co-founder and CEO. Before launching Rox, he founded Pixie Labs, which was acquired by New Relic for approximately $150 million in 2020. He subsequently served as New Relic's Chief Growth Officer.

The founding team brings experience across enterprise technology, cloud infrastructure and artificial intelligence.

• Ishan Mukherjee: Co-founder and CEO, previously founder of Pixie Labs and Chief Growth Officer at New Relic.

• Shriram Sridharan: Co-founder and former founding member of AWS's Aurora database team.

• Diogo Ribeiro: Co-founder and former Google engineer.

• Christopher Ré: Co-founder and Stanford AI Lab professor.

Their combined backgrounds reflect Rox's focus on building AI systems for complex enterprise sales operations.

How Rox's AI Agents Aim to Transform CRM Software

Traditional CRM platforms primarily help businesses organise customer information, track sales interactions and manage commercial pipelines.

Rox is taking a different approach by developing AI agents that can actively work across these processes.

Its agents are designed to:

• Research customer accounts and gather relevant business information.

• Identify and recommend which accounts sales teams should prioritise.

• Prepare customer outreach and sales-related workflows.

• Help commercial teams manage customer relationships through automated intelligence.

The company's broader ambition is to reduce the amount of manual work required from sales professionals while making customer-facing operations more efficient.

Rather than functioning only as a database for sales teams, Rox wants its platform to become an active layer of AI-powered sales execution.

General Catalyst and Other Investors Back Rox's AI Sales Ambitions

The $100 million Series B was co-led by General Catalyst and March Capital.

Returning investors Sequoia and GV also participated, while Prosperity7 joined as a new investor.

General Catalyst has backed Rox since its earlier development stages. Partner Marc Bhargava said the opportunity lies in building AI-native products that are designed around autonomous agents rather than adapting older software architectures.

The investment comes as businesses increasingly explore how AI agents could automate tasks traditionally handled through enterprise software.

Rox's Customer Base and Revenue Growth

Rox has named several businesses among its customers, including Ramp, New Relic, Trafigura, MongoDB, Groq and America's Auto Auction.

The company reports that its annual recurring revenue has increased more than tenfold since its first year after launch. However, it has not disclosed its current ARR.

An earlier TechCrunch report, citing people familiar with the matter, said Rox was projected to finish 2025 with approximately $8 million in ARR. That was an earlier reported projection, not a confirmed current revenue figure.

The company previously announced $50 million in seed and Series A funding in November 2024 from investors including Sequoia, General Catalyst and GV.

Its latest round gives Rox additional resources to expand its product capabilities and commercial operations.

Can Rox Challenge Salesforce?

Rox is entering a market dominated by established enterprise software companies, particularly Salesforce.

The startup's argument is that AI-native platforms can change how businesses manage customer information and sales execution.

Its CEO has pointed to companies moving data away from traditional CRM environments and into their own infrastructure as one factor that could weaken the hold of incumbent platforms.

However, challenging Salesforce will be difficult. Salesforce reported $41.5 billion in revenue for fiscal 2026 and says it has worked with more than 150,000 companies.

Rox is therefore competing not only against an established software product but also against a deeply embedded enterprise ecosystem.

Its opportunity lies in demonstrating that autonomous AI agents can deliver enough value to change how businesses operate their sales organisations.

What Rox's $100 Million Funding Means for AI Sales Automation

Rox's Series B funding reflects investor interest in AI agents that can take on operational responsibilities within businesses.

The company is positioning itself at the intersection of enterprise software, sales automation and artificial intelligence.

Its next phase will focus on improving its AI capabilities, expanding its customer base and significantly increasing its commercial team.

The challenge will be proving that AI agents can reliably handle complex sales workflows at enterprise scale and deliver a compelling alternative to established CRM platforms.

With a $1.3 billion valuation and $100 million in new funding, Rox has secured substantial resources to pursue that ambition.
