Norrsken Impact Fund

Check: Historical Norrsken role. The firm now publishes €1M–€10M tickets, but no personal ticket or present investing authority should be inferred because Christian left for an operating role in 2026.

During his Norrsken tenure, Christian explored frontier technologies where difficult physical environments create enabling infrastructure for Earth: satellites for climate intelligence, microgravity for drugs, semiconductors and materials, and in-space supply chains. His move to Biorce shifts his current work from capital allocation to operating an AI clinical-trial platform.

Khosla Ventures

Check: No personal check range is published. Khosla's Seed Fund supports technical and business-model experiments and may incubate companies; historical firm commentary described many seed investments around $1M–$2M. The Main Fund covers larger early and later rounds. These are firm-level references only.

Katie works at the company-formation boundary, incubating and backing early deep-tech and consumer ideas. Her experience spans satellites, AI research, consumer-company formation, entertainment partnerships, fundraising, recruiting, and product at Fei-Fei Li's Astrocade. That combination supports a thesis around technically novel products whose consumer behavior, narrative, team, and initial distribution can be designed together from day zero.

Alpine Space Ventures

Check: €10M-€20M initial investments. No person-specific check range is inferred for Christina Kotzur.

Christina Kotzur serves Alpine Space Ventures as Chief Financial Officer. The official sources do not publish a separate personal investment thesis, so the profile retains the firm's stated strategy without attributing it personally.

Check: €10M-€20M initial investments. No person-specific check range is inferred for Lynn Zoenen.

Lynn Zoenen works on Alpine Space Ventures's strategy to lead high-conviction investments in European and selected U.S. space-industrial companies with technical excellence, customer traction and major commercial potential. The firm does not publish a narrower personal mandate on the cited roster.

Alpine Space Ventures

Check: €10M-€20M initial investments. No person-specific check range is inferred for Catriona Chambers.

Craft Ventures

Check: No personal check-size range is published. Craft attributes venture and growth investments to Taylor, including a Series B investment in Xona; financing totals are not his personal check authority.

Taylor backs frontier systems and software, with a strong interest in physical AI and resilient infrastructure. His Xona thesis illustrates the pattern: a strategically critical legacy system faces technical and geopolitical limits; a new hardware-software architecture produces order-of-magnitude performance gains; and the product can serve both commercial and defense markets. His finance background also supports attention to capital planning and scaling requirements.

Craft Ventures

Check: No personal check-size range is published. Craft attributes angel through growth investments and a led Series A to Sky; these are portfolio-stage observations rather than personal check limits.

Sky backs hard-technology companies that extend connectivity and intelligence into the physical world. His company-building history—from EarthLink and Boingo to Swarm, Ring, and Joby—supports a lens centered on infrastructure transitions, ambitious technical systems, consumer-grade usability, and businesses that can ride a long adoption curve from enabling technology to everyday utility.
