Harry Nelis is a Partner at Accel in London, where he joined in 2004 as one of the first members of the firm’s London office after working as an engineer at Hewlett-Packard and founding a venture-backed software company. He invests primarily in early- and growth-stage companies across Europe and Israel, focusing on software (especially SaaS), fintech, and consumer internet sectors. His typical investment range is $15 million to $70 million, with a sweet spot around $25 million, and he often leads deals rather than follows. Notable portfolio companies include Celonis, Miro, Funding Circle, and Zepz (formerly WorldRemit Group), several of which have IPO’d or been acquired. Nelis brings a distinctive founder-turned-investor perspective, offering operational guidance grounded in his engineering roots and firsthand startup experience. He has not published widely cited public writing, but his viewpoint is frequently articulated in speaker sessions emphasizing the importance of scaling technology businesses with strong global potential.
