About Decisa

Decisa is an advertising operating system: it combines first-party attribution — connecting paid clicks to the conversions and revenue they actually produced — with draft-based campaign management, where every change to an ad account is proposed, reviewed, applied, and audited.

Why we built it

Platform dashboards grade their own homework: every ad platform reports its own conversions under its own attribution rules. The result is that teams decide budgets on inflated numbers — and the tools that measure the truth can't act on it.

Decisa closes that loop, guided by four principles:

Clarity. Show what is attributed and what is not — no invented matches.
Learning. Explain the evidence behind every number and every recommendation.
Control. Every campaign change is a reviewable draft with an audit trail — nothing applies silently.
Consistency. One canonical view of clicks, conversions, and revenue across platforms.

Who builds it

Decisa is built by Costa Software, founded by Alfredo Costa, and operated by Decisa Tecnologia LTDA, a Brazilian company.
