Five to Nine

Overview

Five to Nine is an enterprise employee engagement and event management platform designed for internal program leaders, HR teams, and Employee Resource Groups (ERGs). The platform automates event scheduling, attendee communication, RSVP tracking, and post-event survey feedback in one central interface. By replacing manual spreadsheets, it gives executives real-time data analytics on employee participation and inclusion initiatives. Five to Nine integrates into existing workplace tools like Slack, Zoom, and calendar suites to streamline hybrid community building.

Founder story

Recognizing that internal corporate programs and Employee Resource Groups relied heavily on manual spreadsheets and fragmented communication tools, the founders built a dedicated SaaS platform to streamline event logistics, track participation, and measure workplace belonging.
