About

What is Keyplay

Keyplay runs AI agents against public web data and firmographic sources to continuously score, enrich, and segment accounts against a backtested ICP model — tracking up to 75K accounts on the paid tier. It's built for RevOps teams, GTM leads, and AEs at mid-market and enterprise companies who need more than static list pulls and want account fit scored on 750+ signals rather than a handful of manual filters. The standout capability is the ability to build custom AI agents that automate specific account research questions and generate unique signals not available in off-the-shelf data providers. Keyplay does not replace outreach or sequencing tooling — it stops at the research and prioritization layer, so you'll need a separate execution stack to act on what it surfaces.

Our verdict

Vanderbuild take

Keyplay is a focused account research and ICP scoring tool — if your RevOps or GTM team is spending cycles manually triaging accounts or arguing about ICP fit, this is the category of tool you need, and Keyplay is a credible option in it. On the agentic readiness front, the API is available and the enrichment endpoint is documented, so you can wrap Keyplay's scoring into your own orchestration layer or MCP setup without too much friction — MCP status is unconfirmed, but the REST access is real. That said, expect procurement involvement: the meaningful tier starts at $20K/year, and intent scoring is custom-priced on top of that, so this isn't a tool you expense on a credit card. The honest limitation is scope — Keyplay is purely a research and prioritization layer, and teams expecting it to also handle outreach, sequencing, or contact-level data will need to budget for additional tooling alongside it.
