The production department for those who don’t have one

Big holding groups have built in-house integrated production. Independent agencies and brands producing without an agency were left without one. Gataria Filmes has become their production department, on demand, and launched its own platform where agency and client follow the whole job in a single link.

Press release · October 2026

Two new tools

Job platform. Every project gets its own link with schedule, approvals, materials and deliveries. Agency and client comment on the cut at the exact second and sign off each stage in one place.

gatarIA. An AI assistant on the website that turns a rough idea into a structured brief, for those who arrive without one. Inside the platform, it also handles job support, answering quick questions about the project in progress.

Gataria Effect. The method is named after the overview effect, the shift in perspective astronauts describe when they first see Earth from above: looking at the whole project so every stage talks to the next.

“What a job lacks most isn’t budget or ideas. It’s someone looking after production from start to finish. We became that person for those who don’t have one.”
Mariana Sierra, founder
