Rubix Ventures

Damien Lui heads investments and research, drawing on his background at 3i and Investcorp. Andy Birley leads portfolio due diligence, applying over 20 years of operational and supply-chain expertise. Dan Martin, the firm's Athlete Partner, also participates in evaluating opportunities, particularly those sourced through the elite sports network.

Rubix's disclosed activity points entirely toward direct investments in operating companies. Its portfolio page lists eleven startups and growth-stage businesses, with no mention of fund-of-funds commitments or LP stakes in other managers. The firm emphasizes operational involvement alongside every check it writes.

Rubix invests from early-stage, seed, and startup rounds through growth and late-stage expansion. Its earliest known position dates to 2013 with the indoor cycling platform Zwift, which it supported through multiple subsequent financing rounds. The portfolio includes pre-revenue companies like Clippd alongside scaling consumer brands such as Mous and Think Better Group.

Managing Partner Andy Birley previously managed a £200m global portfolio at DeutschePost DHL across 16 countries and co-founded an operational excellence advisory, The Detail Group. That firm provides the backbone for Rubix's post-investment engagement. Rubix also draws on a roster of advisors such as Lee Bowman, a communications strategist, and Seonaid Mackenzie, a regulatory incubation specialist with 40 years of financial-services experience.
