Building software the AI way.

The Company

What Is TAG|85?

TAG|85 is a software engineering practice built for the AI era. We provide companies with senior Product Engineers — experienced builders augmented by teams of AI software engineering agents.

Founded in Lisbon, the San Francisco of Europe, we work with organizations globally who need complex, custom software but have historically been priced out of bespoke development. Our engineers embed directly with your team, working alongside your product owners to build software that fits you exactly.

Philosophy

Why We Exist

The software industry's biggest shift since cloud computing is not that AI writes code. It is that AI changes the economics of what can be built.

Software that would have needed a team of ten and a year of runway can now be built by one engineer and a team of AI agents in weeks. TAG|85 exists to bring this new reality to companies who need software that fits them exactly — not the other way around.

Let's Build Something

Whether you need a new product built from scratch or want to understand how AI-augmented engineering can work for your organization.
