Stellar is a European, GDPR-compliant influencer marketing platform designed for brands and agencies that need more structure, transparency, and measurable results from creator marketing. By bringing discovery, campaign operations, reporting, and ROI measurement into one intelligent platform, Stellar helps teams manage influencer marketing with greater precision and confidence.
Used by more than 400 brands and agencies across 20 countries, Stellar is built to support the full influencer marketing workflow without forcing teams into a rigid setup. Its modular approach and AI-enhanced capabilities allow organizations to tailor the platform to their own workflows, reporting requirements, and strategic priorities – so they only pay for the features they truly need.
- Discover Influencers: Find relevant creators up to 60% faster with Stellar thanks to a database of more than 440M profiles, advanced filters, AI-powered social listening, and competitor benchmarking. Teams can build stronger shortlists, uncover creators already gaining traction in their category, and avoid wasted spend from poor fit. Shortlists can also be shared directly with stakeholders or clients, so they can review, approve, and comment online without needing their own Stellar access, reducing email back and forth and speeding up validation.
- Analyze Profiles: Go beyond follower counts with audience authenticity checks, audience and location insights, past partnership visibility, lookalike discovery, and AI-enhanced brand safety. This helps teams assess creator credibility, brand fit, and reputational risk before campaign budgets are committed.
- Forecast Performances: Bring predictive analytics into planning to estimate likely campaign performance, ROI, and EMV before content goes live. This makes influencer marketing easier to justify internally and easier to manage as a measurable growth channel.
- Manage Relations: Keep briefs, deliverables, creator coordination, tracking links, promo codes, and shipping workflows organized in one place. Stellar also helps preserve campaign knowledge across teams over time, making it easier to optimize future activations and scale operations more consistently.
- Report Results: Combine automated content tracking, attribution, social listening, and sentiment analysis to measure both paid and organic impact. Teams can understand audience response, monitor the broader campaign conversation, and report on ROI, EMV, efficiency, and performance drivers in a clearer and more stakeholder-friendly way.
Discover creators with stronger fit and less wasted spend:
Stellar helps brands and agencies find the right creators faster, with less guesswork and less wasted budget. By combining creator discovery with AI-enhanced social listening and competitor benchmarking, teams can identify relevant profiles, spot rising voices early, and surface creators already generating organic traction around a brand, product, or category. This leads to stronger shortlists, better creator fit, and up to 60 percent time savings through Stellar’s smart search engine.
Just as importantly, discovery in Stellar is built for collaboration. Shortlists can be shared directly with internal stakeholders or clients, allowing them to review, approve, and comment on creators online without needing their own Stellar access. That cuts down on email back and forth, accelerates validation, and makes the selection process more efficient for everyone involved.
Analyze creators with more confidence before campaigns go live:
Selecting a creator involves more than audience fit. Reputational risk matters too. Stellar supports safer, more informed decisions by bringing audience authenticity checks, location and demographic insights, past partnership visibility, and brand safety into one workflow.
Its AI-powered Brand Safety feature analyzes available textual content across a creator’s profile, spanning all supported networks, any language, and years of historical posts. It classifies content into 11 risk categories, including threats, violence, self-harm, sexual content, politics, drugs, alcohol, tobacco, war, controversial topics, and coded language such as "algospeak". Each flagged post receives a severity score from 0 to 9, and results are updated daily. The result is a more complete view of creator credibility, audience quality, and brand risk before a campaign goes live.
Forecast campaign performance before budget is committed:
Instinct still drives the planning of too many influencer campaigns. Stellar brings predictive analytics thanks to AI into planning so teams can forecast likely performance, estimate ROI and EMV, and make more confident budget decisions before content is published. That makes influencer marketing easier to justify internally and easier to manage as a measurable, performance-minded channel rather than a leap of faith.
Manage creator relationships without operational drag:
Execution is often where influencer programs become difficult to scale. Stellar keeps campaigns organized end-to-end: briefs, deliverables, calendars, creator coordination, tracking links, promo codes, and product shipping workflows all live in one place. It also protects institutional knowledge by keeping decisions and learnings visible across teams, so brands and agencies can build on what they already know, optimize incrementally, and run a more consistent, scalable creator program.
Measure real campaign impact, not just paid deliverables:
This is one of Stellar’s strongest differentiators. Stellar goes beyond contracted outputs by combining automated content tracking, attribution, social listening, and sentiment analysis into a single reporting layer. Teams can capture both paid and organic performance, understand how people really reacted, and track the broader conversation around a campaign, including community reactions, unpaid content, and competitor signals. Instead of stopping at views and engagement, teams get a clearer picture of ROI, EMV, efficiency, and what actually drove results.
Just as importantly, this reporting layer is built to adapt. Stellar can be customized around the formats, structures, metrics, and stakeholder views each team actually needs. Data inputs can be enriched when needed, calculations can be aligned with internal logic, and for enterprise clients, API connectivity makes it easier to feed influencer marketing data into internal business intelligence environments and custom dashboards. That creates a smoother data flow, a more holistic view of influencer activity, and smarter decisions across the business.
