Onboarding used to be 1:1 and sequential — a bespoke run of meetings, materials, and follow-ups, with a typical ramp of 70–90 days. The cohort model restructured this: groups move through together, collateral consolidates, and each step unlocks the next — agreements before bio, bio before capture, capture before profile build. Ramp dropped to roughly 60 days. It built for our efficiency but also created the peer community contributors named, year after year, as the thing they most wanted. The harder constraint was reach: every module had to work async across different communication styles and technical fluency. One rule governed everything — build for the least accessible format first. Designing for the hardest case is what made the average case fast.
