J12 Ventures

J12 Ventures is an early-stage venture capital firm headquartered in Stockholm, with additional presence in London and Paris. The firm invests in technical founders building artificial intelligence companies across Europe and beyond, backing them early and supporting them over the long term.

Investment activity is organised around two areas. Enablers covers companies that help businesses adopt AI and give builders the tools to create models and applications - spanning data infrastructure, developer tools, MLOps and compute. Applications covers companies applying AI to transform significant business workflows. The resulting portfolio sits at the intersection of AI infrastructure and B2B software.

The team is composed of former founders and operators with company-building and early-stage investing experience. J12 Ventures states a preference for founders displaying ingenuity, curiosity, adaptability and stamina, and frames its approach as backing ambitious, long-term company building rather than short cycles.

The firm operates from three European cities - Stockholm, London and Paris - while its portfolio companies are distributed across Europe and beyond. Founding year, team size and fund size are not disclosed.
