From Dream to Reality:
The Inspiration Behind Duox

Gustavo and Alice met in college, where the idea of transforming the accounting universe was already bubbling. Graduating in 2014 (Alice) and 2015 (Gustavo), they followed paths that led them to work in offices and dive into the tax area – with Gustavo also working for a time in auditing.

Throughout those years, the conversation about innovating in accounting never ceased. Even in different corporate environments, the idea of establishing their own office remained alive and vibrant between the two friends.

In 2019, fueled by experience and mutual trust, they stepped out of their comfort zone and opened the office together, starting with just one client but with a huge vision. Believe it: even starting modestly, the potential was there.

Success came quickly; by 2020, they were already serving more than 20 clients, and even during the challenges of home office imposed by the pandemic, Duox continued to grow.

With the resumption of in-person services in 2022 in Agronômica, they reaffirmed the importance of direct contact with clients. By the end of 2023, this growth allowed the move to a larger room, symbolizing the consolidation and continuous advancement of Duox.

The journey of Duox reveals courage, innovation, and dedication. If you are looking for an accounting service that combines expertise, proximity, and clarity, come meet Duox and transform the management of your business.
