Open Design / Chapter 1 · The Answer HEADLINE ANSWER
Decision / Where should the board point next quarter's spend

Fund ecosystem attach,
not paid-acquisition seats.

Every account that installs a plugin or a design system in its first 30 days expands 2.9x faster than one that doesn't. Seat-only accounts flatten by month four; attach-driven accounts keep compounding. Paid acquisition buys the seat — the ecosystem buys the expansion.

131%
Net revenue retention · attached cohort vs. 96% seat-only

Twelve months of billing data settle it: the two cohorts split the moment a plugin or design system installs, and the gap never closes. This is the point the finance model was built on — the one inflection marked in orange.

Open Design / Chapter 5 · The Ask RECOMMENDED MOVE
Decision / Three moves for the next two quarters

Reallocate $2.4M toward the attach engine.

MOVE 01 · CUT PAID SPEND 20%
Redirect $900K from ads

Paid acquisition sits at 11-month payback; every dollar moved to attach clears in 4.3 months.

MOVE 02 · DOUBLE THE PLUGIN TEAM
6 to 12 engineers, this half

217+ plugins already drive 42% of new ARR; the constraint is supply, not demand.

MOVE 03 · LAUNCH ENTERPRISE SUPPORT
Monetize the attach cohort directly

A paid support tier on top of the free core; modeled at $6.8M incremental ARR by Q4.

Open Design / Voices from the Room VALIDATION
We stopped asking how many seats we sold and started asking how many accounts touched a plugin in week one — that single question now runs the growth plan.
