What is ProfileAPI?
Raw B2B data can be overwhelming and lack the depth needed for truly intelligent applications. ProfileAPI transforms this challenge by providing AI-inferred traits and actionable signals on B2B companies and professionals, directly accessible via API. It's designed for builders like you who need structured, insightful data to fuel smarter search, hyper-personalized experiences, and deeper analytics within your apps and AI agents.
Key Capabilities
ProfileAPI delivers powerful insights derived from continuous AI analysis, giving you a competitive edge:
⚡️ AI-Inferred Traits & Signals: We go beyond simple data aggregation. Our AI analyzes public websites and professional social media to infer rich characteristics (traits) and identify actionable events or attributes (signals) for both companies and people. This provides a deeper, more nuanced understanding than raw data alone.
📊 Comprehensive B2B Coverage: Access data on over 40 million companies and 500 million professional profiles. With over 1 billion AI-inferred traits and signals, you get a vast and trustworthy dataset to build upon.
🧩 Structured & Actionable Data: Receive data in a clean, structured format, ready for immediate integration into your workflows. Key signals cover categories like Company Stage, Hiring Activity, Business Model, Person's Topics of Interest, Education, and more, providing insights you can act on.
🔄 Continuously Updated: Our AI constantly analyzes new information, ensuring the traits and signals you access are current and relevant, reflecting the dynamic nature of the B2B landscape.
