An AI-first technology and consulting practice from Brazil.

§ 01 The founder

Who's behind 21xVentures

Bernardo Campos

Founder · Rio de Janeiro, BR

Bernardo started 21xVentures to do AI-first work across building, advising, and writing. The premise is that a small practice can be more useful by staying close to the work, adapting the approach to each problem rather than fitting the problem to a predefined approach.

He writes here in English and Portuguese, usually about practical questions that come up while building AI systems.

§ 02 Areas of interest

What we focus on

Applied AI where outcomes can be measured: production systems that need rigorous evaluation, decisions about what should and should not be automated, the data and pipelines underneath, and product workflows that change when models enter the loop. The practice is oriented toward work that can be implemented and operated.

§ 03 How we work

A lean core, with project-specific specialists

The core team stays small. For each project, we bring in one or two partners who have lived the problem from the client's side: people with experience in FP&A, equity research, pricing, engineering, or operations. They join the work where their context matters and return to their core roles when the project is complete.

Each project pairs domain experience with production engineering. The team forms around the problem and stays only as long as the work requires.
