About GMIStrategy / design / technology

A team accountable for the product, not only the code.

We connect strategy, design and technology so early decisions still hold when the product reaches production and scale.

Our approach

From decision to outcome.

01

An accountable product team

We stay close to the problem, users and business outcome. Our responsibility does not end when code is handed over.

02

Agreed scope and fixed price

After the workshops, you receive a recommendation, risk map, agreed scope and a fixed price for delivering it.

03

The code and knowledge stay with you

We build readable solutions, hand over documentation and share the knowledge required for future development.

In our client’s words

“From the start of our collaboration, we could count on strong commitment, efficient communication, and openness to our ideas. The team understands our needs well and responds quickly to questions and challenges as they arise.”

History

Responsibility that continues after launch.

Technologies and project scale change. Our role stays the same: help make sound decisions, build the product and take responsibility for how it works.

Evidence you can verify

Have a product to build or a difficult system to untangle?

Let us start with the goal, the risks and the decisions that need to be made before delivery.
