Growth finance for Series A companies: the 90-day install for marketing and creative agencies in Latin America
The exact 90-day plan for standing up growth finance at Series A — the point where the founder can no longer be every function. Written for agency owners and heads of new business in Latin America.
This edition of the Growth Broker playbook is written for agency owners and heads of new business operating in Latin America. In this market, LATAM buyers reward hands-on partnership, local presence, and clear commercial terms, so the way you install growth finance has to be shaped to that reality from day one.
Series A is the moment growth finance 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 CAC payback and gross margin 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.
Inside marketing and creative agencies, the binding constraint is almost always owner-time bottleneck on the sales function, and in Latin America it is compounded by the fact that local partnership depth, not marketing spend is what actually gates growth. Growth finance is only useful here when it is pointed at both constraints at once.
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: optimising for growth rate at any cost. It usually shows up around day 45 when the founder tries to hire ahead of the model.
The Series A version of growth finance looks small compared to what you will build at Series B. That is the point — it is a foundation, not a monument.
Concretely for marketing and creative agencies in Latin America: agencies that install this stop trading time for pipeline and start productising it, and one properly-installed LATAM account becomes a reference across the region. That is the reason it is worth installing growth finance deliberately for this market rather than importing a playbook designed for somewhere else.
