Dos & Co.

Dos & Co.

Dos & Co. launched in 2012 out of an initial engagement with one U.K. family, formalizing the governance, structuring, and lifestyle administration Darragh O'Sullivan had already been providing. O'Sullivan, a barrister by training, chairs the Commercial Education Trust and anchors the firm's legal DNA. The multi-family office now serves entrepreneurs and significant wealth-holders, with a footprint spanning Europe, Asia, North America, and South America. Investment posture is eclectic but disciplined: Dos & Co. writes direct co-investment and SPV checks alongside private equity and real estate mandates, and it participates in secondaries and special situations. The firm explicitly avoids digital assets, activist plays, distressed turnaround, commodities, and sports franchises. Focus sectors tilt toward regulatory-heavy domains — FinTech, InsurTech, LegalTech, RegTech, PropTech — and energy-transition verticals including water, circular-economy, and climate technologies. Geographically, the group has placed capital in properties from the French Alps to London, reflecting a super-prime residential orientation. The group operates four branded subsidiaries that turn family-office capabilities into external revenue. dospay supplies FCA-regulated escrow and payment services for cross-border transactions, M&A, shipyard purchases, and construction retentions. doslab functions as an in-house data and technology unit. HQR Ski manages luxury ski properties, embedding the firm further into the lifestyle-management stack. In November 2023, Dos & Co. became a certified B Corporation with a score of 89.8, formalizing a sustainability commitment already visible in its sector screen. The firm is a founder member of the PRIME Principles for sustainable business and holds associate membership in the British Institute of Interior Design. What separates Dos & Co. is the deliberate fusion of a regulated escrow-and-payments business with a multi-family office structure — both serving the same ultra-high-net-worth client base. Instead of running a pure cost-center family office, O'Sullivan built operating companies that generate revenue on both sides of a transaction, a model far closer to a specialist merchant bank for family principals than a traditional MFO.
