Summary
Rox, a San Francisco-based startup, has raised $100 million in a Series B financing that values the company at $1.3 billion, according to Reuters as cited by Unite.AI. General Catalyst and March Capital co-led the round. Sequoia Capital and Factory, both existing investors, participated, and Databricks Ventures and Prosperity7 Ventures joined as new investors.
The company said it will use the proceeds for AI research and custom-model development while widening its enterprise customer base in healthcare, the industrial sector, financial services, energy and technology. Rox reported that annual recurring revenue grew more than tenfold during its first year in the market. Its customers include Puma, Groq and Ramp.
Rox positions its platform as more than outbound lead generation. According to its documentation, the system covers prospecting, qualification, engagement, closing, renewal and account expansion within one connected architecture. The platform draws on CRM records, email, calendars, Slack, call transcripts, documents and internet sources, and includes a governance layer applying a single access model across systems. Its Outbound Agent validates contact roles and email addresses against more than 17 enrichment providers before outreach, and teams can keep every send under manual review or pause automation.
Rox cited customer deployments including MongoDB, which reportedly moved from prototype to production in 45 days, Ramp, whose conversion rate rose 10% to 15%, Couchbase, with adoption above 90% among more than 250 representatives, and Puma Energy, which uses the platform to monitor customers in key markets. The company cautions that these figures reflect individual configurations and may not represent outcomes for other customers.
The research spending aligns with an agenda described on Rox's research page, covering task-specific models, agent architectures, evaluation systems for agent behavior and production infrastructure. Rox's company page lists Ishan Mukherjee as cofounder and CEO, Shriram Sridharan as cofounder and CTO, Diogo Ribeiro as cofounder and CGO, and Christopher Ré as cofounder for research. General Catalyst also led the company's Series A, which it announced on November 19, 2024. The central question for investors is whether early revenue growth and customer outcomes can be replicated across the broader industries Rox is now targeting.
