Tenant grain versus user grain in B2B SaaS

Seat-level funnels invent expansion. A loud intern clicks through every screen, the chart celebrates, and the invoice does not move. Tenant grain asks a different question: did this workspace do the work it pays for?

Shared logins are not a footnote

In Thailand we still see family-shared devices and a single admin login used by three operators. If your identity graph pretends those are three users, your “power user” segment is a fiction. Usage pattern analysis has to declare grain on every card in the atlas: tenant, seat, or session.

Module 02 of Sequence Atlas spends a full session on this. People arrive impatient. They leave able to say, in one sentence, which chart is about accounts and which is about clicking.

Expansion is an account event

Seat adds, billing changes, and admin invites belong on the tenant timeline. Individual feature tours belong on the seat timeline. Mixing them produces a slide that says “engagement predicts expansion” when all you measured was that admins click more in the week they buy seats — because they are buying seats.

We keep a counter-example in class: a logistics workspace whose DAU fell while they added two countries. The tenant path was healthy. The seat path looked like churn. Finance only cares about the first.

What to do on Monday

Label every weekly chart with its grain. If you cannot, stop presenting it. Then pick one tenant journey — month-end close, approval queue, or first record — and ignore seat-level vanity until that journey is named. The pattern atlas is the artefact; the courses are how we teach you to fill it.
