Droidrun raises €2.1M to scale open-source AI framework for mobile app automation

German startup Droidrun has secured €2.1 million in pre-seed funding led by Merantix Capital, with participation from Sixty Degree Capital and angel investors including Mandeep Singh, Felix Jahn, and Peter Sarlin, as the Osnabrück-based company scales its breakthrough open-source framework enabling AI agents to control mobile apps through natural language commands.

Founded in 2025 by Peter Lächner, Droidrun tackles a persistent challenge in mobile automation where traditional tools rely on fragile screen vision approaches that frequently break with interface updates. The company's innovative solution bypasses visual analysis entirely, instead converting mobile app interfaces into structured text that large language models can reliably understand and interact with, effectively transforming any mobile app into a programmable API.

Central to Droidrun's breakthrough is their innovative approach combining visual UI parsing and accessibility APIs to enable precise, robust interaction with app elements. This allows AI agents to perform complex tasks like booking trips, making purchases, extracting data from mobile-only apps, and automating workflows through simple natural language commands rather than manual scripting.

The open-source framework went viral within weeks of launch, attracting thousands of developers and gaining 3.9K GitHub stars while securing integration into major AI platforms. Droidrun supports multiple LLM providers including OpenAI, Anthropic, and Gemini, while offering planning capabilities for complex multi-step tasks and self-healing automation that adapts to app changes.

The company also provides a cloud platform for running AI agents at scale across multiple devices in parallel, featuring credential management and complex workflow orchestration. With mobile devices being the primary interface for daily activities, Droidrun's native mobile control capabilities position the company at the forefront of agentic AI development.
