Investment thesis

SXC backs moonshots emerging from Alphabet's X, The Moonshot Factory, under an exclusive partnership that gives it the right to invest in X spinouts. It targets technology projects once they are de-risked and poised for transformative economic impact, then builds them into independent, category-defining companies. Every company it backs has already passed through X's rigorous technology incubation funnel, where hundreds of ideas are evaluated and only a few graduate into standalone companies. Backed by $600M from premier investors including Alphabet, the fund provides runway, company-building resources and commercial freedom to scale, with returns intended to fuel the next wave of X projects.
