No licenses
No licenses to manage

Participate on as many teams as you need — your own and others'. One account, one calendar connection, full visibility everywhere you collaborate.
Built for collaboration
Your teams, your way
Create as many teams as you need. Join teams others have created. Every team has its own members, availability view, and scheduling — across any combination of organizations.
Consultants & agencies
Get every project team aligned in minutes
Managing multiple client engagements means coordinating across multiple organizations simultaneously. Create a team per project, invite stakeholders from any company, and see everyone's availability in one view — no back-and-forth emails, no calendar tennis.

- Manage dozens of cross-company projects from a single workspace
Enterprise teams
Stop burning licenses on external collaborators
Every vendor, contractor, and partner you add to Microsoft 365 or Google Workspace costs a full license — and creates a security surface you have to manage. Timeslot gives external collaborators calendar visibility at a fraction of the cost, with zero access to your internal systems.
- No guest licenses, no E3/E5 seats, no Google Business licenses for externals
- Vendors connect their own calendar — you never touch their credentials
- When a project ends, there's nothing to clean up or deprovision
