Get Named When People Ask AI Where to Buy or Sell
Buyers and sellers increasingly ask ChatGPT, Perplexity, and Gemini which marketplace to trust before they ever open an app. Subsig tracks whether your marketplace is recommended, monitors what AI says about your trust and safety, and helps you close gaps before the next transaction goes to a competitor.
Trusted by teams building their reputation in the AI era
Every trade starts with someone asking AI who to trust
Marketplaces live and die by trust between strangers. Now AI is the first thing people ask before they buy, sell, or list. Subsig makes sure that answer points to you.
