Customer onboarding for Series A companies: the 90-day install for healthcare and life sciences
The exact 90-day plan for standing up customer onboarding at Series A — the point where the founder can no longer be every function. Written for commercial leaders at healthtech, medtech, and life-sciences companies.
This edition is written for commercial leaders at healthtech, medtech, and life-sciences companies. In healthcare and life sciences, healthcare buyers move under regulatory constraint and reward domain-specific messaging, so the way you install customer onboarding has to reflect that reality from day one.
Series A is the moment customer onboarding stops being optional. The founder has to step out of some of the work, the plan requires a defensible growth number, and every quarter compounds toward the next raise.
Day 1 to 30: diagnosis and instrumentation. Name the constraint, write the ICP, wire time to first value into the board pack.
Day 31 to 60: first live cycle at 20% of planned volume. Founder still in every review. Kill criteria written and enforced.
The binding constraint we see in healthcare and life sciences is almost always regulated-sale cycle length, not intent. Customer onboarding is only useful in this vertical when it is pointed at that constraint — not at a generic growth number borrowed from another category.
Day 61 to 90: ramp to full volume, hire the first dedicated operator, and hand off ops. Founder retains strategy and the weekly review.
By day 90 the metric is legible and the trajectory is defensible. This is what turns a Series A story into a Series B round.
Trap most Series A companies fall into: onboarding checklists that document handoffs instead of driving outcomes. It usually shows up around day 45 when the founder tries to hire ahead of the model.
The Series A version of customer onboarding looks small compared to what you will build at Series B. That is the point — it is a foundation, not a monument.
Concretely for healthcare and life sciences: the healthcare teams that install this get past procurement instead of dying in it. That is the reason it is worth installing customer onboarding properly rather than half-heartedly across three vendors.
