Ploid

YC company profile

The people data company for the agent era

Ploid is the AI-native people data infrastructure for developers and companies building products, workflows, and agents around people.

We've built an index of 2B+ people across professional and social sources, giving developers one API to search for people, enrich profiles, find emails and phone numbers, resolve identities, and retrieve up-to-date information from across the web. Unlike traditional people databases built around static records, Ploid combines its massive people index with real-time retrieval and identity resolution, delivering fresh, reliable information whenever it's needed. From sales and recruiting to customer intelligence, trust and safety, and AI agents, Ploid replaces fragmented data providers with a single infrastructure layer.

2B+ people. One API. Built for AI.
