Subsig is out of stealth
and live on AppSumo
Get recommended by AI, not competitors. Subsig is social listening for the era of AI: visibility, reviews, communities and agents in one place
Product screenshot, dashboard
We built Subsig to enable a new world of social listening in the era of AI, to help businesses understand how they show up across AI search, reviews, online communities, and the other conversations that shape their reputation
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. Whether a model recommends you comes down to everything already said about you.

Are we the name the model says out loud?
Four features, one product
AI visibility
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
Reviews
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
Communities
Mentions across Reddit, Hacker News, X, GitHub and LinkedIn, scored by relevance so you spend time on the ten that matter
AI SEO agents
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
Chosen by
AppSumo picked Subsig for their potential and innovation collection
We took that as a reason to put the full product in front of early users rather than a trimmed version of it
The Subsig team
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.”

Launch questions
Everything worth knowing about the AppSumo deal before you buy.
Is this the same product as on subsig.com?
Yes. The AppSumo deal is the full product, priced as a one-time purchase instead of a subscription.
What happens when the deal ends?
Your tier stays yours. Nothing switches to a subscription later, and future updates to your tier are included.
I already pay monthly. What now?
Nothing changes for you. If a lifetime tier suits you better, contact us before buying and we'll sort the overlap.
Can I try it before deciding?
Start on the free plan, run your first report, then take the deal while it's live if it earns it.
