Jenn Hartzler

Of Counsel

Jenn helps ambitious founders and teams realize their visions by drawing on her 15+ years experience working across industries and jurisdictions in start-ups, scale-ups and Biglaw. She began her career practicing international arbitration at Herbert Smith in London, working with clients spanning Europe, the Middle East, Africa, Asia and the Americas, in various industries and sectors navigate their most complex and big-ticket disputes. Then Uber happened: a secondment to Uber showed her what it felt like to build something instead of arbitrate about it later. She was hooked. Since then, Jenn has spent her career in fast-paced, emerging tech companies leading, building and scaling in-house legal functions, including as Head of Legal at AlphaSights, and most recently as General Counsel/Company Secretary at Candy Digital, an institutional-grade NFT digital collectibles company and marketplace. Jenn's practice focuses on various aspects of the digital assets ecosystem (including NFTs, blockchain and token launches, DAO and other decentralized governance structures, stablecoins, real-world asset tokenization, and the convergence of traditional finance and DeFi), while at the same time providing the soup-to-nuts support an early-stage company requires.
