Summary

Senior🎓
Top SchoolHarrison Hara is a finance executive and advisor with nine years of entrepreneurial experience and a decade-plus track record at Goldman Sachs, where he rose to Managing Director in FICC and led cross-border structured credit and alternative sales. He has steered startups from founding through rapid scale and exit—serving as COO and board member at Cellid where he grew headcount from 3 to 45 and drove valuation from JPY1B to JPY15B, then as CFO at UPSIDER executing a dual-track exit, sizeable equity and debt raises, and strategic partnerships prior to acquisition. Harrison combines institutional capital markets rigor with hands-on operational execution in deep-tech and fintech, building ALM frameworks, refinancing complex debt stacks, and transitioning working capital from equity to debt to accelerate growth. Known for aligning board governance, investor relations, and transaction execution, he’s equally comfortable negotiating with global tech partners and leading investor syndicates in Japan. Based in Minato, Tokyo, he leverages a Hitotsubashi economics background and Goldman provenance to help founders translate product momentum into sustainable enterprise value. An uncommon strength is his ability to marry relationship-driven banking strategies with startup agility to unlock balance sheet-driven growth.
