Tenbin for Outside Directors — Manage Board Commitments Without Conflict
As an outside director serving multiple boards, you receive a Google Workspace account from each company. Board meetings, committee calls, and one-on-ones pile up — but no calendar sees the full picture. Tenbin does.
Average outside director serves 2–4 boards simultaneously.
64% of board meetings are now scheduled virtually (post-2020).
Board meeting conflicts create real governance risk.
Why Outside Directors Need a Different Approach
- Each company provides its own Google Workspace.
- Board meetings are often scheduled by company secretaries.
- No one knows about your other board commitments.
- Result: scheduling conflicts between Board A and Board B.
- Unlike employees, you can’t ask IT to “sync your calendars” across companies.
The Governance Risk of Calendar Conflicts
- Missing a board meeting due to double-booking is a governance failure.
- Rescheduling board meetings affects many busy executives.
- Compliance meetings (audit committee, etc.) can have regulatory deadlines.
- Your availability accuracy is a professional obligation.
How Tenbin Works for Board Members
- Connect each board’s Google Workspace account.
- Tenbin reads free/busy across all accounts (not board meeting agendas).
- When a company secretary needs to book you, share your Tenbin link.
- They see your real availability across boards.
- The event is created on the appropriate board calendar.
Confidentiality Guarantee
- Board A cannot see Board B’s meeting titles or agendas.
- Tenbin reads only free/busy status via Google’s FreeBusy API.
- No event details (titles, descriptions, attendees, documents) are accessed for aggregation.
- OAuth tokens are encrypted at rest (AES-256-GCM).
- Data retention: deleted within 90 days of account disconnection.

FAQ
- Will the board secretary need a Tenbin account?
- No. You share a booking link. The secretary picks an available time in their browser — no account or app install required.
- Can I restrict bookable hours for board meetings?
- Yes. Set available hours per booking page — e.g. “Board availability: Tue/Thu 10am–4pm JST.” Personal time stays protected.
- Is Tenbin compliant with corporate governance expectations?
- Tenbin accesses only free/busy status — never board materials or meeting content. It uses Google OAuth 2.0 with encrypted token storage. No board-confidential information is processed or stored for aggregation.
