XO Life Tech Stack

Patient data collection platform for pharmaceutical real-world evidence

Hospitals and Health Care Munich, Bavaria 11–50 employees Founded 2021 Public Company

XO Life operates a SaaS platform that collects patient-reported outcomes and real-world evidence for pharmaceutical companies. The tech stack—Python, Vertex AI, TensorFlow, PyTorch, and Snowflake—reflects a data science and ML-heavy foundation, yet hiring is concentrated in senior engineering and design roles rather than data science, suggesting the platform's core value now lies in product experience and compliance rather than model innovation. Active projects center on consumer experience and design systems, aligned with the pain point of balancing user usability against strict safety and regulatory requirements.
