Richard Rankin

Richard S. Rankin (FINRA CRD# 2110632) is a career investment banker who now runs his own family office. He began on the sell side at First Manhattan Co. in early 1991, then spent roughly seven years at UBS Securities / Union Bank of Switzerland (1991–1998, reportedly as a Vice President). He passed his Series 7 exam in January 1991, early in this period.

From 1998 to 2005 Rankin was at Morgan Stanley & Co. in New York, where he rose to Managing Director. According to industry profiles, he headed the firm's Canadian Investment Equity Division across New York and Toronto, opened offices in Calgary and Montreal, and later returned to New York as a member of the firm's management group (including the North American Management Committee and Capital Commitment Committee).

In 2005 Rankin founded Atheneum Capital, LLC, a Norwalk, Connecticut single-family office that manages the private wealth accumulated during his banking career. Atheneum makes principal investments in private and public companies, providing growth capital to early-stage enterprises across life sciences, green energy, and technology. Alongside the family office he has held a series of registered roles: General Manager of Atheneum (2005–present), CRT Capital Group in Stamford (2011–2012), Chief Marketing Officer at Eachwin Capital (2016–2017, the source of the `@eachwincapital.com` contact), VP–Portfolio Specialist at Fiera Capital / Foreside Fund Services (2017–2020), a 2021 consulting stint at KB Financial, and most recently Client Relationship Manager at Dock Street Asset Management in Palm Beach, FL (2023–present). He passed the SIE (2018), Series 63 (2017), and Series 65 investment-adviser exam (2024). FINRA lists no disclosure events on his record.

*Note: Atheneum's contact records list Norwalk, CT, but the current atheneumcapital.com site presents a Newport, RI "generational wealth" positioning — treat firm branding details as evolving.*

• Stage: Seed/early-stage and growth-stage; provides "vital growth capital to early-stage enterprises," per family-office records.
• Sectors: Life sciences and healthcare services, green energy / climate tech, and technology.
• Structures: Direct co-investments, special purpose vehicles (SPVs), private equity, and private credit — not just passive angel checks.
• Selection lens: As a former Morgan Stanley MD and ex-Eachwin CMO, Rankin's background emphasizes assessing management-team quality and investment merit in individual companies (Eachwin's core philosophy was "invest in companies with superior management").
• Geography: North America–focused, run from Connecticut with a Palm Beach/Florida footprint.
