Rox, which builds AI agents that research accounts and prepare sales outreach, raised a $100M Series B at a $1.3B valuation co-led by General Catalyst and March Capital, with Sequoia and GV returning and Prosperity7 joining. Founded by Ishan Mukherjee alongside Shriram Sridharan, Diogo Ribeiro, and Stanford's Christopher Ré, the company says ARR has grown more than tenfold since launch across customers including Ramp, MongoDB, Groq, New Relic and Trafigura. Mukherjee says the goal is 'autonomous agents doing customer-facing commercial work across large parts of the economy.'
