Ian Rosmarin

Ian Rosmarin is a Toronto-based entrepreneur and investor best known as the founder of Prime Quadrant, an ultra-high-net-worth advisory and family-office firm he launched in 1998 (originally as a single-family office). Over a career spanning more than 30 years, he has advised wealthy families on financial strategy, investing, and structuring, and built Prime Quadrant into a firm whose annual Prime Quadrant Conference draws hundreds of Canadian investors and single-family offices alongside leading global investment names. In February 2019, Prime Quadrant joined Focus Financial Partners, the global partnership of independent wealth-management firms; Rosmarin is today the firm's Chairman Emeritus.

Originally from South Africa, Rosmarin is a graduate of the University of the Witwatersrand in Johannesburg and placed first in the South African Institute of Chartered Accountants' Final Qualifying Examination in Auditing. He holds a strong professional-credential stack: member of the Chartered Professional Accountants/Institute of Chartered Accountants of Ontario, Certified Investment Management Analyst (CIMA), Chartered Life Underwriter (CLU), and member of the Society of Trust and Estate Practitioners (STEP).

Before and alongside his advisory work, Rosmarin built a record as an operator and entrepreneur, having established, purchased, run, and sold several businesses. He was a senior officer at Henry Schein — the world's largest company serving in-office healthcare practitioners — where he founded Henry Schein Financial Services and led the practice-management software division serving tens of thousands of U.S. healthcare practices. He separately runs Rosmarin Equity Partners, his own Toronto vehicle for private-equity and real-estate investing, and it is through this entity (rosmarinpartners.com) that he is reached for direct, early-stage/angel deals.

Beyond investing, Rosmarin is active in governance and philanthropy. He has served on several corporate boards, including the board of an Alberta-based chartered trust company, chairs the investment committee of Canadian Friends of the Hebrew University (CFHU), and is a supporter of the Jewish Foundation of Greater Toronto alongside his wife, Pam.

• Vehicle: Invests personally through Rosmarin Equity Partners, whose stated mandate is "investing in private equity & real estate" for sophisticated, high-net-worth investors.
• Stage: Listed as a seed-round / angel investor; given his operating background, he is positioned for early-stage and growth private-equity opportunities rather than purely institutional venture rounds.
• Sector lean: Generalist with credible depth in financial services, wealth/family-office structures, and healthcare-practice technology (drawn from his Henry Schein Financial Services and practice-management software experience).
• What likely earns a "yes": A strong operator/founder, a clear path to profitability and capital structure, and businesses that map to his financial-services, real-estate, or healthcare-services expertise — he has personally built, bought, and sold companies, so operational substance over hype is consistent with his track record.
• Geography: Canada-first, Toronto-centered, with North American breadth.
