How Fractional CTOs and CFOs Manage Scheduling Across Multiple Companies

· Norimitsu Shida · Kiruck Inc.

Kurz

Fractional leaders serve 3–6 companies with separate Google Workspace accounts that cannot see each other. Tenbin connects those accounts, reads only free/busy for availability, and exposes one booking link — up to 10 accounts, $10/month base (2 included) + $3 each additional. Clients do not see other companies' event titles.

The rise of fractional leadership

Startups want C-suite expertise without full-time cost. Market growth has been strong since 2022 — exact statistics vary by source, but demand for fractional CTO/CFO roles is widely reported as rising.

A day in the life (scheduling edition)

Board call on startup A, sprint on B, investor call on C — while three people try to book you via email. Without merged availability, you risk double-booking.

The booking link problem

If your link only checks one tenant’s calendar, it can offer a slot that conflicts with another tenant — even when each calendar looks “free” locally.

How Tenbin solves this

1) Connect accounts. 2) FreeBusy merged. 3) Set available hours in your timezone. 4) Pick destination calendar per booking page. 5) Share one URL with every client.

Protecting your time

Outside your defined hours stays unbookable even if a calendar looks empty — critical for deep work and recovery.

FAQ

No. Availability uses busy intervals only — not titles, attendees, or descriptions across tenants.
