Portfolio highlights

  • Ludus AI — Ludus AI is a technology company introducing a next-generation solution for the 3D game and visualization industry. The startup, founded by Piotr Penar, former CEO of DreamStorm Studios, aims to facilitate the creation of high-quality content in Unreal Engine by using artificial intelligence.Unreal Engine, although recognized as the best tool forcreating 3D experiences, presents significant challenges for creators. Complicated documentation and complex processes often lead to extended production times and increased costs. Ludus AI was created in response to these problems, resulting from the founder's direct experience in managing a 60-person team of developers during a 9-year journey through the gaming industry and working on projects for Microsoft, Google and UPS.We've created a comprehensive set of tools that significantly speed up work in Unreal Engine, offering users not only the basic capabilities offered by AI technology, such as project and blueprint analysis, but also the innovative ability to automatically create objects in virtual space based solely on a description.Ludus AI solutions are used in many industries. Game studios can significantly accelerate the development process of projects, architectural firms gain the ability to quickly create interactive visualizations, and the training and simulation sector can more effectively create advanced training environments. The technology also works in the automotive industry in the design of user interfaces and in film production in the creation of virtual film sets.We're building tools that we needed ourselves when running a game studio. The reality is that many teams can't afford to hire senior Unreal developers, yet they need to deliver high-quality projects. Our tools bridge that gap, making professional-grade development accessible to teams of any size.The company, which recently released the first version of its solution, is already attracting the attention of the industry, has over 5,000 users and plans further expansion into international markets. We secured our first investors with 1,000,000 PLN in funding, including Hartmann Capital and one private-equity investor. We also joined the EU’s top Concordia Design Accelerator. In the coming months, Ludus AI will focus on the stability of its product, adding more features to its assortment and developing its most frequently used and most effective tool, which is the creation of 3D objects by description.
