Crosscut Ventures Research

Investment Thesis

Crosscut Ventures invests in early-stage frontier technology companies addressing humanity's most pressing problems. Founded in 2008 in Los Angeles—defying conventional wisdom about venture capital geography—the firm partners with visionary entrepreneurs building category-defining solutions in deep tech, hardware, and software. The investment philosophy centers on the belief that exceptional founders emerge from technical communities (particularly SpaceX, Anduril, Northrop, and Boeing in Southern California) and develop ambitious visions that transcend typical startup thinking. As Brian Garrett notes, "When they think about starting a company, they don't come with small ideas. They're thinking about big, hairy problems that humanity is facing."

Frontier Technologies:

  • Defense systems upgrade
  • Supply chain resilience and reshoring
  • Underwater exploration and marine technology

Business Models:

  • Hard tech and deep tech (hardware-centric)
  • Software companies serving frontier tech ecosystems
  • Blended portfolios combining hardware and software elements
