Summary
Early‑stage investment thesis and operating focus: Glenn is an early‑stage generalist investor (VP at Jump Capital) who hunts in application software, vertical/B2B SaaS, AI, Future of Work, and FinTech. He emphasizes extreme product‑market fit and founder teams that can drive near‑zero CAC through strong customer advocacy, and he combines product/operator instincts (ex‑LinkedIn product strategy) with hands‑on support for portfolio companies. jumpcap+2
Community building and founder networks: Glenn co‑founded inVest Ventures, a community VC fund supporting LinkedIn alumni founders, and operates publicly as a community‑oriented investor (Substack, LinkedIn/X outreach). This indicates a focus on leveraging networks, operator advisors, and alumni relationships to source and support early deals. glennborok+1
Founder empathy informed by personal background and founder experience: Son of immigrants and a brief founder (Trajectory), Glenn foregrounds immigrant founder support (Unshackled Ventures fellowship) and American resilience (work at In‑Q‑Tel). His investing philosophy blends empathy for founder journeys with disciplined product and market evaluation. substack+2
