How it works

Managing Sales Pipelines

Users can visualize their deal stages using Kanban views (e.g., New, Engaged, Proposed). They can track key deal information, including associated companies, contacts, and amounts, to manage their sales process effectively.

Centralizing Customer Communications

Users can synchronize their email inbox with the CRM. Emails are logged against relevant company and contact records, allowing teams to maintain a shared, up-to-date history of all customer interactions directly within the platform.

Customizing for Unique Business Needs

Users can import their customer data and then customize the CRM's data model by creating new objects and fields. This allows them to structure the platform around their specific operational data and unique processes.

Key Points

  • It is backed by Y Combinator (YC S23).
  • The platform is designed to provide the simplicity of a SaaS product with the freedom and control of self-hosted open-source software.
