Ionworks was founded in 2023 by Valentin Sulzer and Rob Timms, experts with backgrounds in mathematics, physics, and engineering. The idea emerged from their work on PyBaMM, the world’s leading open-source battery modeling software, which they developed and which is widely used by battery engineering teams globally. Recognizing that many battery companies lacked the time or expertise to build and maintain their own simulation software, they launched Ionworks to commercialize and scale this technology, making advanced battery simulation accessible and efficient for industry users[2][3][4].
Early traction came from the adoption of PyBaMM in academic and industrial labs, validating the demand for simulation-driven battery design. Ionworks builds on this foundation by offering a cloud-based platform that accelerates battery innovation through virtual prototyping and collaboration tools[2][3].

Ionworks rides the trend of digital transformation in battery development, analogous to how CAD revolutionized structural engineering and CFD transformed aerodynamics. The timing is critical as the battery industry faces $100 million, five-year development cycles that bottleneck innovation in electric vehicles, consumer electronics, and energy storage. Market forces such as the global push for electrification, demand for faster product cycles, and advances in cloud computing favor Ionworks’ simulation-as-a-service model[2].
By enabling virtual prototyping and data-driven design, Ionworks influences the broader ecosystem by lowering barriers to entry for battery innovation, accelerating R&D timelines, and fostering more sustainable and efficient energy storage solutions. Its integration with lab equipment and scalable cloud infrastructure positions it as a key enabler in the shift toward digital battery engineering[3][5].

Looking ahead, Ionworks is poised to expand its platform capabilities, deepen integration with battery manufacturing workflows, and broaden its customer base across automotive, consumer electronics, and grid storage sectors. Trends such as increasing battery complexity, demand for faster innovation cycles, and growing adoption of digital twins will shape its journey.
Ionworks’ influence may evolve from a niche simulation tool to a foundational platform in battery design, potentially setting industry standards for virtual prototyping and lifecycle optimization. Its continued leadership in the PyBaMM community and cloud-based delivery model will be critical to scaling impact and maintaining competitive advantage.
In summary, Ionworks is accelerating battery innovation by transforming how engineers design and validate batteries, helping to unlock faster, cheaper, and more reliable energy storage solutions that are vital for the future of clean technology.
