Partnerships and co-selling for startups under 20 people for marketing and creative agencies 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 partnerships and co-selling has to be shaped to that reality from day one.

The under-20-person version of partnerships and co-selling is not a diluted enterprise playbook. It is using another company's distribution to reach buyers you cannot cost-effectively reach yourself with different constraints: no headcount, no politics, and no time to be wrong for long.

Own it personally as a founder or lean-in operator for the first quarter. Hiring a specialist too early replaces context with process.

Pick one channel, one trigger, one message. Two of anything at this stage is too many and none of them will work.

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. Partnerships and co-selling is only useful here when it is pointed at both constraints at once.

Instrument sourced and influenced pipeline from partners in a spreadsheet if you have to. Legibility beats sophistication under 20 people.

The startup-specific trap is signing MOUs no one operationalises, usually because a well-meaning advisor points at what worked at their $50m company. Ignore.

Budget rules: whatever you spend on tools, spend the same on the person operating them. Under-tooling is fine; under-humaning is not.

A working partnerships and co-selling function at 15 people is a genuine moat — most competitors of that size do not have one, and the discipline carries forward as the company grows.

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 partnerships and co-selling deliberately for this market rather than importing a playbook designed for somewhere else.
