01The company
A base for global products
Incorporated in Delaware to operate without borders, with products designed from day one for multiple languages and markets.

Origin
Legal tech and AI in Brazil
The global operation rests on the founder's experience building SaaS for the legal sector and artificial intelligence applications in Brazil.
03How we build
Four decisions that apply to every product
The same technical standard across every brand in the portfolio, from the first commit to deployment.
AI applied to the product
Artificial intelligence goes where it solves a real user problem — not as screen decoration.
Cloud-native on AWS
Everything runs in containers on AWS: repeatable deployment, predictable cost and room to grow on demand.
Security and privacy by default
Minimal data, credentials outside the code, end-to-end HTTPS and restricted access as the default.
Multilingual from day one
Portuguese, English and Spanish are born together in the product — never a translation project bolted on later.
04Global presence
Between Brazil and the world
Headquarters in the United States, roots in Brazil and products ready for global reach.
