## About

1.5° Ventures was established by Jan-Gisbert Schultze and Dr. Fabian Heilemann. Schultze also serves as a partner at Acton Capital. Heilemann founded AENU, a climate tech fund that shares leadership overlap with 1.5° Ventures. The firm targets early-stage start-ups and growth companies. Its strategy covers direct investments in venture opportunities. Geographic reach centers on Europe with additional exposure through partner networks. Confirmed relationships include AENU as a co-investor and Tobias Lechtenfeld as a partner who also directs Net Tech for Zero. Team size and total deployment figures remain undisclosed. The firm lists no additional offices beyond its Berlin headquarters. It participates in the WIN Initiative and Impact Hub networks. No operational events from the last 24 months appear in available records. The structure links two founders who retain parallel roles at established European venture firms. This creates a hybrid sourcing model through existing capital networks rather than a standalone mandate.
