Venture Partner at Craft Ventures
Check size: 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.
Describe the physical or network constraint and why a systems-level technical change makes it solvable now. Bring performance data, deployment architecture, hardware and software integration, manufacturing and supply chain, regulatory milestones, unit economics at scale, partnership strategy, and evidence that the product can move from specialized early adopters to broad everyday use.
Scrappy, technically ambitious founders pursuing infrastructure-scale shifts; products that make complex networks or hardware usable in daily life; defensible engineering tied to a large deployment surface; and teams with the persistence to navigate manufacturing, regulation, partnerships, and long commercialization cycles.
No explicit personal pass list is public. His record implies weaker fit for shallow hardware concepts without a systems moat, capital-intensive plans lacking deployment milestones or regulatory strategy, infrastructure with no route to widespread utility, and teams unprepared for long technical and commercial cycles.
Test whether a difficult network or physical system has a defensible technical architecture, credible deployment and regulatory plan, improving unit economics, and a product experience that can translate infrastructure into widespread daily use.
Craft's operator-led strategy assigned Sky a hard-tech focus based on his EarthLink and Boingo experience and highlighted his Series A leadership in satellite-connectivity company Swarm Technologies.
