What Calejo does

Calejo Hybrid Intelligence AB is a Swedish deep-tech company founded in 2017, headquartered in Tärnaby, Sweden, with R&D in Stockholm, sales in Berlin, and a UK office. The company builds Calejo Optimize™, a single core product that is an industrial process optimization engine based on patent-pending Gray Box (Hybrid Intelligence) modeling. The platform combines mathematical white-box physics models with AI black-box neural networks in any combination, supports Differential-Algebraic Equation (DAE) compatible modeling with variable time-step solving, and is built on the Open Modelica foundation with proprietary AI blocks. It creates digital twins of industrial processes, runs real-time multi-objective optimization, and is positioned as a step toward autonomous industrial operations; integrations span Azure, Siemens, ABB, SAP, SQL, Oracle, IBM Maximo, and generic IoT platforms.

Calejo serves enterprise and government customers across four primary verticals: municipal water and wastewater (Kungälv Municipality, Swedish municipalities), mining (Boliden Aitik, plus a joint industry project with LKAB), process industry / pulp and paper (SCA Obbola, broader SCA forestry supply-chain digital twin), and energy / hydropower (Uniper). Reported outcomes include 15-25% energy efficiency improvements in wastewater treatment, double-digit percentage energy reductions at pulp mills, and improved turbine efficiency at hydropower plants. A sub-brand, Calejo Smart Energy, addresses energy producers and consumers for forecasting, load balancing, and waste reduction.

The business model is sales-led enterprise: custom pricing, multi-year contracts, on-site joint workshops, and a structured four-stage implementation (digital twin creation, process optimization, operator interface, verification and final delivery). Marketing is primarily content-driven through website articles, case studies, and newsletters. Distribution is direct enterprise sales in Europe augmented by a strategic partnership with Global Kinetics for U.S. market entry; funding to date consists of an Almi Invest round and a Vinnova grant explicitly directed at U.S. expansion. Revenue is not publicly disclosed and the company is small (1-10 employees) with commercial pilots underway in Sweden and Italy.

Core offering

Calejo sells Calejo Optimize™, an industrial process optimization engine that uses patent-pending Gray Box (Hybrid Intelligence) modeling to combine mathematical white-box physics models with AI black-box neural networks. The platform creates digital twins of industrial processes, performs real-time multi-objective optimization, and is deployable across edge, cloud, and desktop environments for industrial and municipal customers in mining, pulp and paper, hydropower, and water/wastewater sectors.

Product overview

Calejo offers a single unified product: Calejo Optimize™, an industrial process optimization engine built on patented Gray Box (Hybrid Intelligence) technology that combines physics-based mathematical modeling with AI neural networks. The platform creates digital twins of industrial processes, enables real-time optimization, and supports the evolution toward autonomous industrial operations. Calejo Optimize integrates with existing industrial systems (Azure, Siemens, ABB, SAP, Oracle, Maximo, IoT platforms) to collect operational data and presents results through existing dashboards, SCADA systems, or its own instrument panel.
