Profound is a marketing platform built for the era of AI-powered search. As AI assistants like ChatGPT, Perplexity, and Google AI Mode replace traditional search engine results pages, brands are losing control of how they're described to consumers. Profound gives marketers tools to monitor how AI systems talk about their brand, measure visibility and sentiment across major AI platforms, create AI-optimized content that those systems cite, and deploy autonomous agents that handle research, content generation, and publishing end-to-end. The platform covers three layers: analytics/intelligence (Answer Engine Insights, Conversation Explorer, the Profound Index), content creation (AI-optimized articles, comparisons, social posts), and agentic execution (Profound Aim, Profound Agents). Buyers are enterprise marketing teams — over 15% of the Fortune 500 — across CPG, financial services, retail, pharma, and tech. Founded in mid-2024, it reached a $1B valuation in 18 months.
