I built the tool I wished I had.

After spending years inside Brazilian accounting firms and optimizing operations for international holding companies, I realized that true strategic analysis was broken. So I coded the solution from scratch.

The Founder & The Heritage

Thesum wasn't conceived in a Silicon Valley garage. It was built by a Software Engineer born in the interior of the Brazilian Northeast—in a small city called Jaguaquara—whose career spanned across Canadian holding companies and US-based international firms with operational bases in Mexico and Paraguay.

Before writing a single line of code for this platform, I worked directly inside Brazilian accounting firms as a consultant. With deep operational experience in accounting—gained through real, field-tested work rather than just a bachelor's degree—I spent years optimizing their internal tools and witnessing the exact bottlenecks that stall true strategic analysis.

Thesum is the direct result of that convergence. Beginning in 2022, I immersed myself in the early research groups mapping out Agentic AI, tracking the evolution of predictive models up to architectures like Google's DS-STAR in 2025. I spent those years continuously coding, iterating, and pitting my financial decomposition models against the absolute top human analysts in the market. I refused to launch until the predictions were equal to or better than the experts. The state-of-the-art finally caught up to the vision. And the machine is now ready.
