About Ploid
Summary
Ploid builds people data infrastructure for developers and companies that need reliable, up-to-date information about individuals at scale. Its index covers over two billion people drawn from professional, social, and web sources, unified through entity resolution into a single profile. Developers access it via API, CLI, or MCP to power sales tools, recruiting products, customer intelligence, identity resolution, and AI agents, replacing a patchwork of static data integrations and stale exported records.
Business model
Usage-based API access with a demo and pricing tier structure.
Go-to-market
Developers and companies adopt Ploid through self-serve API, CLI, and MCP integrations, plugging directly into agents and platforms they already use such as Claude, Cursor, and ChatGPT without migration.

The people data company for the agent era
Ploid is the AI-native people data infrastructure for building products, workflows, and agents around people. We’ve built an index of 2B+ people across professional and social sources, with the infrastructure to search, resolve, enrich, and retrieve up-to-date information about anyone on demand. Through Ploid’s API, CLI, and MCP, developers and companies can search for people, enrich profiles, find emails and phone numbers, resolve identities across different data points, and access the broader web context associated with a person. Unlike traditional people databases that rely primarily on static records, Ploid is designed for AI-native workflows. We combine our people index with real-time retrieval and entity resolution so data can be refreshed and expanded at the moment it is requested. Ploid can power everything from sales and recruiting products to customer intelligence, identity resolution, trust and safety, and AI agents that need reliable information about people. Instead of building and maintaining dozens of data integrations yourself, Ploid gives you one infrastructure layer for people data. 2B+ people. One API. Built for AI.
