## A week of launches that give back to the market and show who we are.

From May 4 to 8, 2026, we held our first Launch Week and delivered 5 free tools to the ecosystem to open up the market. One tool launched per day, and a legacy that reflects our culture and what we believe in.

- **Transparency:** We play with our cards on the table. If something doesn't make sense for you, we say so. If it does, we show the numbers.
- **Deep technical expertise:** We are the leading Open Finance specialists in Brazil. It isn't marketing, it is what we do every day, and have for years.
- **Pioneering:** The first proxy for the regulated ecosystem. A model unique in Brazil, unlike anything else in the market.
- **Partnership:** Even when the solution isn't under our roof, we help. We connect, teach, open doors. Creating value for the ecosystem is part of our DNA.
