About Clay

Clay is a go-to-market data platform built around a spreadsheet-style interface where each row represents a person or company and each column is an API call, auto-populating from chained data providers like Apollo, Hunter, and OpenAI in a 'waterfall' that tries source after source until a verified answer is found. This waterfall approach typically yields 90 to 95% contact accuracy by paying for redundancy across providers, reportedly outperforming single-vendor data by 12 to 18% on email validity according to a 2025 G2 report. Clay's pricing looks inexpensive at the platform level, but costs scale with usage: credits are consumed per data element per record, and Action Credits introduced in March 2026 now meter every workflow step including API calls and CRM pushes, adding a variable cost layer some users have called a "workflow tax." Premium data sources like ZoomInfo and Apollo must be brought separately rather than being included.
