What WindSim does
WindSim is a Norwegian wind energy software company founded in 1993 and headquartered in Tønsberg, Norway. Its core product is a simulator designed to model and optimize the energy production of wind turbines and wind farms, serving customers across Europe, Asia, Australia, and North America. The company positions itself as a specialist vendor within the wind farm development value chain, supplying engineering and resource-assessment tooling rather than a broad horizontal SaaS product.
The firm operates as a small, focused organization with 11-50 employees, consistent with a niche specialist. Leadership is founder-aligned: Arne Reidar Gravdahl serves as CTO and Founder, and Donna Rennemo serves as President and CEO. WindSim's website (windsim.com) was inaccessible due to a CAPTCHA verification page at the time of data collection, which limits visibility into detailed product architecture, pricing, and customer references.
The company has only one documented funding event — a $738,000 seed round in November 2007 led by Sarsia Seed Management — with no subsequent rounds disclosed in the available data, implying either organic, self-funded growth or capital efficiency. Its revenue model, pricing structure, customer segmentation, and go-to-market motion are not disclosed in the supplied data, and no patents, awards, partnerships, or named customers were identified.

WindSim competitors and assessment
Company assessmentBroad incumbents
- DNV: Global energy consultancy (formerly including Garrad Hassan) offering wind energy consulting, software tools, and due diligence services. Overlaps with WindSim in energy yield assessment but operates at much greater scale across multiple energy sectors.
- Vaisala (Leosphere): Provides LiDAR-based wind measurement solutions (formerly Leosphere) that feed wind resource assessment workflows. Adjacent competitor to WindSim, supplying hardware and data that complement simulation.
- UL Solutions (OpenWind): Owns the OpenWind wind farm design and resource assessment software (originally from AWS Truepower). Competes directly with WindSim in wind farm layout and energy yield modeling.
Direct peers
- Meteodyn: Provides wind resource assessment software (Meteodyn WT) and consulting services for wind farm design and yield estimation. Direct competitor in CFD-based wind simulation software.
- NRG Systems: Supplies wind measurement equipment (met masts, LiDAR) and resource assessment services to the wind industry. Overlaps with WindSim in the wind resource assessment value chain.
- Vortex: Provides wind resource and energy yield assessment data and software services to wind farm developers, financiers, and operators. Competes directly with WindSim in pre-construction wind modeling and analytics.
- EMD International: Developer of windPRO, a leading wind resource assessment and energy yield software suite used by developers worldwide. Direct competitor to WindSim in wind simulation and resource modeling for both onshore and offshore projects.
Emerging players
- DTU Wind and Energy Systems (WAsP): Develops the WAsP (Wind Atlas Analysis and Application Program) suite, a foundational wind resource modeling tool widely used in academia and industry. Overlaps with WindSim in wind resource assessment methodology.
