Customer onboarding for Series B companies: scaling without breaking for healthcare and life sciences in Latin America

This edition of the Growth Broker playbook is written for commercial leaders at healthtech, medtech, and life-sciences companies operating in Latin America. In this market, LATAM buyers reward hands-on partnership, local presence, and clear commercial terms, so the way you install customer onboarding has to be shaped to that reality from day one.

Series B is the stress test for customer onboarding. What worked at fifteen people fails at fifty unless the operating rhythm is deliberate.

The Series B move is to separate the model owner from the operators. One senior human owns strategy, time to first value, and the weekly review; a small team runs the machine.

Add a second geography or segment only when the first one is producing a defensible number for two full quarters. Not before.

Inside healthcare and life sciences, the binding constraint is almost always regulated-sale cycle length, not intent, and in Latin America it is compounded by the fact that local partnership depth, not marketing spend is what actually gates growth. Customer onboarding is only useful here when it is pointed at both constraints at once.

Governance appears at Series B — that is fine, provided it accelerates rather than slows. The test is whether reviews still make decisions or just distribute updates.

The Series B failure mode of customer onboarding is onboarding checklists that document handoffs instead of driving outcomes, amplified by headcount. Fix the root cause; do not paper over it with more people.

Compensation begins to matter now. Pay operators on time to first value outcomes, not on effort. Effort-based comp at Series B produces theatre.

A well-run customer onboarding function at Series B is the moat that survives to Series C. Companies that skip this discipline burn through raises trying to buy it back.

Concretely for healthcare and life sciences in Latin America: the healthcare teams that install this get past procurement instead of dying in it, and one properly-installed LATAM account becomes a reference across the region. That is the reason it is worth installing customer onboarding deliberately for this market rather than importing a playbook designed for somewhere else.
