Technological change rewards those who know how to use it

We help technical organizations turn data, software, and new methods into more efficient handling of information, higher-quality designs, and better decisions.

Expert services

Data-driven services for infrastructure planning

We build services where engineering judgment, historical data, and machine learning come together to improve how infrastructure projects are assessed, planned, and delivered.

  • Ground-condition and geospatial analyses for early-stage infrastructure planning
  • Automated solutions for design and calculation processes
  • Design assignments that draw on our strong industry expertise

Systems for technical operating environments

We build systems and interfaces for settings where data comes from work sites and other locations, and has to serve real users in their day-to-day work.

  • Site condition monitoring and management solutions
  • Data collection and utilization for renewable energy assets
  • Clear interfaces for end users and APIs for agentic workflows

Consulting services for technical organizations

We help technical organizations adopt new technology. From our own experience we know where and how AI is worth using, and what needs to be considered when planning an AI strategy.

  • A clear model for building an AI strategy
  • Hands-on support for seeing development projects through and transferring the know-how
  • Lasting change in processes and measurable benefit in the long term as well

Background

Crestia brings together engineering and systems experience built over two decades across different industries.

On the engineering side, we have strong experience in energy infrastructure: transmission lines, substations, foundation and structural design for demanding projects, plus renewable energy and telecom structures. Our background includes hundreds of projects for grid operators, contractors, and other operators in Finland. We also have experience from other construction and manufacturing industries.

On the systems side, we have built integrations, monitoring solutions, and data platforms across construction, energy, and industrial operations: measurement systems, dashboards, and data infrastructure that grounds decisions in real information.
