FAQ

Questions we often get

Envixo is an AI-native software company. Senior engineers directing AI agents build our own SaaS products and custom software for clients: web apps, APIs, iOS and Android apps, desktop apps and AI agents, plus modernization of legacy systems.

Any technology. Because AI is part of every step of our process, we are not tied to one stack: we pick the language, framework and cloud that fit the problem, and we also take over and evolve systems already written in older technologies.

AI agents write much of the code, tests and documentation, and our senior engineers direct them, review every change and own the architecture, security and product decisions. The result is delivery in weeks of what used to take months, without giving up quality.

Yes. We audit the current system, plan the migration and rewrite or move it to new technology without losing URLs, data or customers, then tune performance and cost in production.

Envixo has offices in San Francisco (USA), Leiria (Portugal) and Rio de Janeiro (Brazil), so our engineers work close to clients' time zones in North America, Europe and Latin America.

Envixo was founded in 2007 by Patrick Espake, a software engineer and the author of Learning Heroku Postgres, published by Packt.
