Henry Mason is a Partner at Dawn, with a particular focus on automation, data and security. He is drawn to founders with technical depth and a clear-eyed view of how their category works.

His investments include Quantexa – first backed in 2018 and now the global category leader – and Oneleet and Onum, the latter acquired by CrowdStrike less than 18 months after the initial investment. He has also supported his founders through exits to Tenable, Everfox, Collibra and Reveal. Away from deals, Henry drives Dawn’s own AI and automation agenda, applying to the firm the same thinking he backs in others.

Henry joined Dawn in 2016 when the firm was just five people, from a background in technology consulting in government and financial services. His PhD in Greek language and literature from Oxford focused on tech disruption of an early kind – the written word in the 8th century BC, and the transition from oral tradition to texts.

Outside Dawn, he has a long-standing interest in how cities, systems and civilisations get built.
