Overview

Gatekeeper

Gatekeeper is a centralized platform designed to help you take control of your entire contract lifecycle and vendor relationships. Instead of losing track of renewal dates in messy spreadsheets, you can store every agreement in a searchable, secure repository with automated alerts. This ensures you never miss a termination window or get hit with an unexpected auto-renewal fee again.

You can also streamline your procurement processes using the built-in Kanban workflow engine to route approvals and sign documents electronically. The platform is built for mid-market and enterprise teams who need to mitigate risk and ensure compliance across their global supply chain. By automating repetitive administrative tasks, you can focus on strategic relationship management and cost-saving initiatives rather than manual data entry.
