Closebook

A CRM that tells the team what to do next.

A B2B sales CRM with a visual pipeline, deal health scoring and an AI copilot that reads activity and recommends the next best action — built around how your team actually sells.

The problem

Leads live in inboxes, spreadsheets and people's heads.

Growing B2B teams outgrow spreadsheets but find enterprise CRMs heavy and generic. Reps skip data entry, managers can't trust the forecast, and deals stall silently.

  • Pipeline updated only before reviews
  • No signal when a deal goes cold
  • Forecasts built on gut feel
  • Off-the-shelf CRMs don't match the sales process
The solution

Capture activity automatically and turn it into guidance.

Closebook syncs email and calendar, scores deal health from real engagement, and suggests concrete next steps. Stages, fields and rules match your process instead of a vendor's template.

  • Email & calendar auto-logging
  • Deal health from engagement signals
  • Copilot next-best-action
  • Forecast by commit / best case
