Strengths and weaknesses
- +Waterfall enrichment chains 150+ data providers under one subscription, materially raising email/firmographic match rates versus any single source
- +Combines enrichment, AI web research (Claygent), and signal monitoring (funding, hiring, job changes, tech installs) in one platform
- +Spreadsheet-style table UI plus Clay University make complex multi-step enrichment accessible without code
- –Dual credit/action model causes fast, hard-to-predict credit burn; auto-recharge billing reportedly fires without advance warning
- –Steep learning curve, reviewers cite hours in week one and 2–3 weeks before workflows are reliable
- –Phone/mobile number coverage is weak (~30–35% match rate)
- +Official Node (@fiberai/sdk) and Python (fiberai) SDKs
- +Three MCP servers (v3 OAuth, v2 API key, lite) and a first-party plugin
- +Agent-native docs: per-operation markdown, llms.txt and openapi.json
- –No free tier; entry plan $300/month
- –Trial requirements conflict between homepage and pricing page
- –No confirmed official status page or SLA
