J12 Ventures

J12 Ventures backs founders early at the frontier of AI, investing at pre-seed and seed in visionary founders across Europe building solutions that enable the development of AI models and applications, and solutions that apply AI technologies to mission-critical workflows. The firm invests across two core segments: Enablers — foundational software powering AI including data infrastructure, developer tools, the full MLOps lifecycle, and next-generation compute efficiency — and Applications — domain-specific products that combine deep domain insight with advanced AI technologies such as predictive ML, computer vision, generative models, and agentic systems to reinvent mission-critical B2B workflows. J12 looks for founders with outlier ingenuity, childish curiosity, and the stamina to prevail, partnering at the earliest stages to support them for as long as it takes to build a generational company.
