He has held the Director of Product Management title since July 2024, while his role as Product Lead for Linea dates to February 2023.

David Cunningham

Global Head of Institutional Business

David Cunningham is Global Head of Institutional Business Development at Consensys, a position he has held since March 2026. In this role, he leads Consensys' institutional business across financial services, corporates, and financial market infrastructure, with responsibility for building global partnerships with banks, asset managers, payments providers, and market infrastructure firms, and for driving the commercialisation of digital asset and tokenisation solutions. He works directly with product and engineering teams and engages senior executives, regulators, and industry bodies to support the adoption of next-generation financial infrastructure.

Outside his commercial career, he co-founded the Galway City Innovation District in March 2015, a voluntary initiative undertaken alongside Galway Chamber of Commerce to establish a downtown hub for startups. The initiative led to the renovation of a former Guinness storehouse and the opening of PorterShed in April 2016, a coworking space housing up to 35 companies and 130 people. The project subsequently secured €2.5 million in government grant and sponsorship funding to develop a second building intended to accommodate up to 1,000 people.
