Get recommended by AI, not competitors. Subsig is social listening for the era of AI: visibility, reviews, communities and agents in one place
If AI doesn't know you exist, you don't exist
Pius spent years on growth at Meta, Canva, and his own startup, then AI wiped it all out and he rebuilt three times. One day he asked ChatGPT what to launch next, and his old company wasn't in a single answer. That's when it clicked: if AI doesn't know you exist, you don't exist. So he built Subsig to fix the signals AI reads. Over 200 brands are already tracked, and now it's live on AppSumo.
Your buyers are asking an AI which tool to use
And you have no idea what it said. The answer is assembled from reviews, threads, and comparison posts you don't own.

Four features, one product
See the prompts where AI names you, a competitor, or nobody, across ChatGPT, Perplexity and Google AI Overviews, with every citation traced to its source
Ratings and sentiment from G2, Capterra, Trustpilot and more in one view, with alerts on rating drops and review spikes before your buyers see them
Mentions across Reddit, Hacker News, X, Youtube and LinkedIn, scored by relevance so you spend time on the ten that matter
Root cause analysis on a ranking that moved, a prompt coverage roadmap, and source fixes ranked by how fast they lift citations
A few months of heads-down building
Subsig started as a review tracker. Then users stopped asking about their rating and started asking why an assistant named a competitor instead of them
Out of stealth
What early users say
“Subsig helped us get a clear, structured view of how Photoroom shows up across AI-driven discovery and reputation channels. That visibility made it much easier to prioritize where to focus and move faster with confidence."
Matt Rouif
Co-founder & CEO Photoroom
“Subsig helped us clearly understand how Notary compared to competitors across reputation, trust signals, and AI-driven discovery. That insight allowed us to focus our efforts where competitive gaps actually mattered.”
Jakobus Schuster
CEO @ notarity
“From my experience scaling Trustpilot’s early sales motion, strong reputation signals fundamentally changed sales efficiency and became a meaningful driver of revenue growth. Today, those same signals increasingly shape visibility across AI-driven discovery as well.”
