Why not an agency, a freelancer or an in-house team?
You have options. Here is how a senior team that directs AI agents, and runs its own products in production, compares with the usual ones.
| Traditional agency | Freelancer with AI | Hiring in-house | Envixo | |
|---|---|---|---|---|
| First version in production | Months, after a long discovery phase | Fast, but rarely production-ready | Months of hiring before work starts | Weeks: AI agents write, seniors direct |
| Who builds it | Mostly junior and mid-level staff | One person, often outside their stack | Your team, once you find it | Senior engineers directing AI agents |
| Quality | Depends on who is assigned | Unreviewed AI code, few tests | Depends on who you manage to hire | Every change reviewed, tested and measured |
| Before work starts | Hourly estimates that keep growing | Hourly, availability varies | Salaries, benefits and turnover | A plan with scope and timeline |
| After launch | A new contract for every change | Often gone when you need them | Yours to keep, if they stay | We keep it running in production |

Built for founders and product teams
For founders and product and operations leaders who need software shipped without building a senior team first: a new product, custom software, a legacy rewrite or AI in the team you already have.
Custom Software Development
Custom software for startups and enterprises: web, mobile, desktop and APIs. From MVPs to complex platforms, built by senior engineers working with AI agents.
MVPs & New Products
Go from idea to a product in users' hands in weeks. With AI, a small senior team builds what used to take a whole department.
Modernization & Migrations
Legacy systems rewritten or moved to new technology without losing a URL, a record or a customer. We audit, plan and migrate.
AI Adoption & Team Augmentation
Senior engineers who join your team and bring AI-driven workflows with them. Ship more with the team you already have.

We literally wrote the book
Envixo's founder is the author of Learning Heroku Postgres, published worldwide by Packt. The depth that goes into writing a technical book is the same depth we bring to every database, migration and production system we build for you.
What the book covers
- Running PostgreSQL in production in the cloud
- Backups, rollback, followers and forks
- Performance tuning, caching and full-text search
- PostGIS and database extensions
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 a software engineer, the author of Learning Heroku Postgres, published by Packt.
You do. The code, designs and data we create for your project belong to you, in your own repositories and accounts.
After the first call we send a plan with scope, timeline and price. New products and modernizations are usually a fixed scope; ongoing work and team augmentation are billed monthly.
Book a call at calendly.com/envixo or email [email protected]. We discuss your goals, suggest the right approach and send a plan with scope and timeline.
