Keyplay
Account scoring you can inspect and backtest, now part of Inflection.
Keyplay builds ICP models and scores accounts against them, with visible signal weights and backtesting on your CRM data. Scores sync to Salesforce or HubSpot. Inflection.io acquired Keyplay in April 2026, and Keyplay now describes itself as merged with Inflection.
