Efield

Efield AB, operating as Efield Solutions, was a specialized technology firm focused on the simulation of electromagnetic phenomena. The company was established in Sweden in 2006 and carved a niche in providing an integrated modeling and simulation environment for the 3D analysis of complex electromagnetic applications.

The firm's core business centered on offering advanced simulation capabilities tailored to clients in the communications and networking hardware sectors. Its technology was specifically applied to microwave design, antenna design, and antenna integration, addressing the intricate challenges of how electromagnetic fields behave in and around these components. This allowed engineers and designers to model, analyze, and optimize their products in a virtual environment before physical prototyping.

Efield's business model was rooted in providing this specialized software and simulation environment to its clients. The company successfully navigated the early stages of a technology startup, securing a Seed Round of funding in April 2006, the year it was founded, followed by a secondary transaction in early 2008. Its primary financial backers included notable investors such as KTH Chalmers Capital, Saab Ventures, and Verdane.

After operating for approximately five years and reaching a revenue-generating stage, Efield AB was acquired by the ESI Group on December 15, 2011. This acquisition marked a significant milestone, integrating Efield's specialized electromagnetic simulation tools into the broader portfolio of its new parent company.
