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.

The firm leans on the personal networks of its partners and advisors. Dan Martin's position in professional cycling provides direct lines to founders in fitness, wellness, and consumer goods. Managing Partner Andy Birley's advisory firm, The Detail Group, and advisor Ashley Unwin's relationships from PwC and TPG also serve as origination channels. The firm's website pitches itself as an access point to opportunities typically reserved for institutional investors.

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.

Rubix does not fit neatly into either category. It operates as a for-profit asset manager running a concentrated venture portfolio, but its origins tie directly to the personal capital of Dan Martin and a deal-by-deal, operational turnaround approach. The firm describes itself as the operating layer between capital and reality, suggesting a hybrid model that blends investment with active operational support.

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.

There is no public mention of a foundation or philanthropic vehicle tied directly to Rubix Ventures. The firm's advisory board is integrated into its corporate function rather than operating as a standalone entity. Investment committee member Alex Yew holds board roles at non-profits, but these are separate from the Rubix platform.
