Semiotic is a San Francisco, California-based technology company that develops artificial intelligence design agents specifically engineered to generate professional-grade landing pages for technology startups.

Backed by Y Combinator as a participant in the accelerator's Fall 2025 batch, the early-stage startup currently operates with a core team of three employees. The platform utilizes generative artificial intelligence to produce customized web interfaces, aiming to eliminate the lengthy wait times and substantial capital requirements typically associated with professional design services.
