What Stellar is
Stellar is an influencer marketing platform available through the web and API. Its creator search covers more than 440 million profiles and supports discovery by image, content and brand mentions. AI reviews creator text, images, video and audio, while checks cover audience authenticity, brand partnerships and brand safety. The safety scan assesses sensitive content across 12 categories and detects fake followers and artificial engagement. For measurement, Stellar tracks campaign posts, stories, reels and videos and reports engagements, views, clicks, sales, EMV, ROI and costs. Reports can be exported to Excel, PowerPoint or PDF or delivered through the API. MCP access connects with ChatGPT, Claude and Gemini, and API connections support campaign data, creator lists and workflows. White-label reports, custom criteria and brand-specific creator scores are available. Discovery Radar starts at €299/mo billed annually; Campaign Manager starts at €899/mo billed annually. Both listed plans include three users.
