Sarah Eldon Cullen is a corporate and venture finance lawyer (Advokat) at Mace in Copenhagen, advising founders and investors at the frontier of tech, AI and venture capital from early fundraising through to exit. She trained at top-tier firms Kromann Reumert and Bird & Bird, alongside in-house legal roles at Trustpilot and Flyhjælp, and across every role has built the tools and systems her teams were missing: the first IP framework at Trustpilot, an automated litigation workflow at Flyhjælp, and at Acquinex an LLM-based due diligence project that secured £185,000 in internal investment. When that project hit the gap between legal and engineering, she taught herself backend development and shipped a working prototype of an autonomous LLM workflow for due diligence, published openly on GitHub. The same instinct now extends outward: she writes on AI strategy in legal practice, advises other firms on legal tech, and is an active part of the Copenhagen Legal Tech community.
