Content marketing managers at mid-size SaaS companies have spent a decade optimizing for Google rankings, but a growing share of discovery now happens inside ChatGPT, Perplexity, and Gemini, where there is no ranking report, no search console, and no clear feedback loop. When an AI assistant answers a buyer question, it cites a handful of URLs and names a few brands. Today a content team has almost no way to know whether their pages are among those cited, which competitors are, or what wording triggers inclusion. Karmable Brand Monitor for AI-Cited Sources closes that gap. It tracks which URLs and brand mentions get surfaced and cited across ChatGPT, Perplexity, and Gemini for a defined set of prompts, then reports share of citation, missing topics, and competitor gaps so teams can optimize content for AI discovery. The MVP is a prompt-monitoring engine: a user imports target queries and tracked domains, Karmable runs those prompts against the three assistants on a schedule, parses the cited sources and brand name mentions, and produces a dashboard showing citation share over time plus which pages won or lost citations. Revenue is a straightforward B2B SaaS subscription, tiered by number of tracked prompts and domains, aimed first at the single budget holder who already pays for Semrush. Go to market starts narrow: sell to content marketing managers at mid-size SaaS companies through founder-led outreach and free citation audits that show a prospect exactly how often they are cited versus named competitors. Growth loops come from the audit itself being shareable inside marketing teams, from competitor benchmarking that pulls in named rivals as leads, and from published visibility reports that themselves become AI-citable content.
