profileAPI Review

profileAPI, from the team behind Truebase, is a developer-first source of B2B profile data. Instead of static firmographic fields, it returns profiles enriched with AI-inferred traits and signals, insights derived from the data rather than just the data itself, refreshed weekly and augmented with real-time company and people intelligence. The API is built for embedding: developers wire it into apps, AI agents, custom workflows, and smarter search or personalization features.

Key Features

• AI-inferred traits and signals on people and companies
• Real-time company and people insights
• Weekly updated B2B profiles
• Powers smarter search and personalization
• API access designed for developers
• Supports custom workflows and AI agents

Who It's For

profileAPI targets developers and technical teams building products or internal tooling that need B2B intelligence: an AI SDR agent that reasons about a prospect, a recruiting product ranking candidates, a data science pipeline scoring accounts. Sales and marketing teams benefit downstream, but the buyer is whoever writes the integration. Pricing starts at $27 per user per month on the Starter plan, an unusually accessible entry point for a B2B data API, with higher volumes priced beyond that.
