About us

We are an investment holding involved in businesses that show a high potential growth and a positive impact on society. We also work on Nelson and Nara Sirotsky’s family assets management.

Our essence

Achievement and retribution, multiplying dreams.

A Nara and Nelson Sirotsky’s dream. A burning desire to celebrate a family’s values,
history, and tradition. A craving to keep alive the flame of passion, work, ethics, trust,
courage, and entrepreneurship for the next generations.
