Crosslink Capital runs "Alpha," a nearly 20-year-old proprietary network of ~2,000 handpicked members (70% founders/CEOs, 20% pre-seed/seed VCs, 10% large-company executives) that operates as a broad ecosystem utility rather than a house list, designed "for founders first" rather than as a marketing channel. The firm has institutionalized "plausible science fiction" as an explicit investing lens, backing companies just outside the current edge of technical possibility and bringing a repeatable playbook for commercializing defense and deep-tech R&D.
