Prox

Based in San Francisco, California, Prox is an artificial intelligence software company developing multimodal technical support agents for complex physical products. The platform utilizes advanced knowledge graphs and large language models to process dense technical manuals, wiring schematics, and computer-aided design files for industrial equipment such as HVAC systems, CNC machines, and electric vehicle charging stations. Operating with a two-person team, the early-stage startup is backed by Y Combinator as part of its Fall 2025 accelerator batch. Unlike horizontal customer service platforms such as Zendesk, Prox focuses specifically on high-value business-to-business retail sectors requiring specialized domain expertise that cannot be easily outsourced. The enterprise system features expressive voice support, video processing, and generative visual capabilities to assist field technicians with intricate troubleshooting and installation procedures. Formerly known as Dart Labs, Prox was founded in 2025.
