Proximal Says Revenue Run Rate Topped $200 Million After $15 Million Seed Round

Proximal says its annualized revenue has passed $200 million after a $15 million seed round led by General Catalyst at a $300 million valuation, putting the 40-person startup in the center of the race to train better coding agents. The San Francisco company says it uses AI systems to generate coding tasks, evaluations, and post-training data for other AI models, an automation-heavy approach it argues can keep costs below more manual data-labeling work.
