Gráinne Barron is a technology entrepreneur, investor and senior UK Government capital investment leader whose career spans venture capital, institutional investment, technology, innovation and transatlantic economic development.

Based in San Francisco, she is Head of Institutional & Venture Capital for the UK Government in North America, working at the intersection of government and private capital to deepen investment between the United States and United Kingdom. Her remit includes relationships with leading US venture capital firms, institutional investors, pension funds and other major pools of capital, alongside UK companies, funds and government institutions.

Her work is particularly focused on frontier and strategically important sectors including AI, defence and dual-use technology, aerospace, quantum, advanced manufacturing, energy and life sciences. She works with investors and companies on UK investment, co-investment, expansion and market access, while helping connect capital with government, research, procurement and the wider UK innovation ecosystem.

Before joining the UK Government, Gráinne spent more than a decade as a technology founder and CEO. She founded and led Viddyad, a venture-backed AI and video technology company operating between San Francisco and Europe, building the business from inception, raising venture capital, developing enterprise technology and working with major global companies. Earlier in her career, she founded two digital media businesses in Ireland.

Her experience extends across venture investing, research commercialisation and corporate innovation. She has served as an Entrepreneur in Residence and advisor within the US venture and accelerator ecosystem, including work with NEC Corporation, Alchemist Accelerator and the University of Colorado, and has advised technology companies and founders on fundraising, commercialisation and international expansion.

Gráinne was also appointed by the Irish Government to the Governing Authority of the University of Limerick, where her work included strategy, governance, financial transformation, innovation and the commercialisation of university research and intellectual property.

Having lived and worked across San Francisco, New York, London and Dublin, she brings an unusually broad perspective spanning founder, investor, board and government roles. A consistent thread throughout her career has been connecting technology, capital and institutions to help ambitious companies scale and to strengthen the ecosystems around them.

Today, her work is increasingly concentrated on one of the defining economic questions of the coming decade: how private capital, government and technology can work together to finance innovation, rebuild strategic industrial capacity and deepen economic and technological cooperation between the United States and its closest allies.
