Modernization doesn’t always mean replacement.

For Efacec, we created a unified interface that simplifies complex workflows while preserving the knowledge and capabilities already embedded in existing systems.

The result? A more consistent, resilient and future-ready operational platform.

70% are already moving forward.

Modernizing legacy isn’t just about technology,
It’s about unlocking scalability, speed, and future growth.

The real question is: what’s holding the other 30% back?

🚗 From underused tool to performance driver.

We redesigned a Commercial Proposal Simulator for a leading European car rental company, turning slow, repetitive workflows into a fast, intuitive digital experience.

✔ Less friction
✔ Faster proposals
✔ Higher adoption

Result? Up to 50% faster development and 80% more design consistency.

When internal tools work better, business moves faster.

From operational complexity to a scalable platform.

Efacec and Hi Interactive worked as one team, combining transportation expertise, UX, UI and front-end development to create a unified experience built around real operational workflows.

Interface Legacy Cost Calculator

Your interface legacy doesn't show up in any budget line.
But you're paying for it every quarter. 💸

I'm sure you've read it: 33% of dev time lost to tech debt. 50% slower delivery. 40% higher maintenance costs.
Sound familiar?

We built a calculator to help you make visible the invisible cost of interface legacy. 👇

From idea to component… without the usual friction.

What if you could turn a simple request into a structured, ready-to-use component in seconds?
Less back-and-forth. Less ambiguity. More building.

Because speed isn’t just about coding faster, it’s about starting smarter.

From Structure to Velocity: Double Diamond vs. Stingray Model

As AI moves from experimentation to enterprise scale, methodology becomes a strategic choice.

Is it structure or speed?
Risk mitigation or market acceleration?

What if the future isn’t choosing between the Double Diamond and the Stingray Model, but knowing how to orchestrate both?

A perspective on blending architectural thinking with AI-amplified velocity.

Now at out blog: https://hi-interactive.com/blog/from-structure-to-velocity-double-diamond-vs-stingray-model/

Speed, consistency, and scale, delivered.

We partnered with Colliers to create a unified design system that empowers faster development, brand consistency, and scalable digital growth across web and mobile applications.

The result?
Less rework. Faster time-to-market. A solid foundation for future expansion.
