AI-native marketing agency and a self-serve CRM platform for small businesses, with its own client dashboard and automation engine.
Eight live products. One person. No investors, no logos borrowed from anyone else.
Don Gastón is the umbrella over everything Carlos Martinez builds and runs — a marketing agency and CRM platform, a fractional-CMO SaaS, a real-estate marketplace, three media properties, a photography business, and a public safety utility. Each one is a real, independently live site. This page just lists them plainly.
The portfolio
What's actually live
An AI-native fractional CMO, sold self-serve on its own separate infrastructure — three plans, no sales call required.
A real-estate marketplace for La Serena and Coquimbo, Chile — pay-per-lead to local brokers, with a full property appraisal tool.
Sim-racing gear guides and affiliate content, alongside the Realtape YouTube channel — the same audience, two formats.
Bilingual poker news, strategy, and tournament coverage, in English and Spanish, running since 2009.
Photography services, quoted per project.
Live earthquake, weather, and official SENAPRED emergency alerts for Chile — free, no account required.
A guide to golf in Chile — the country's federated clubs, course information, and tour coverage, written for players and for the clubs themselves.
Chile Spirits
In development
An online liquor store. Not launched yet — the domain is reserved and the build hasn't started.

About
How this is run
Don Gastón has no outside investors and no employees beyond Carlos. Every property above is built, deployed, and operated directly — most run on the same shared infrastructure (an InMotion hosting account per property, deployed through GitHub), and each one stands on its own rather than cross-selling the others.
NetWebMedia is the oldest and largest of the group; the rest were built after it, each testing a different kind of product — a marketplace, a media property, a public utility — under the same operator.
