Built by an operator,
not a consultant.

Nexus was founded by Riaan Daly-Evans in January 2026 to provide hedge funds, asset managers, family offices, and investment startups with senior operational and financial leadership on a flexible basis.

With 30 years of institutional buy-side experience, including 14 years as COO/CFO of ADG Capital Management, where he joined as the second employee and helped grow the business from $25 million in seed capital to $3.9 billion AUM, Riaan brings hands-on experience across the full investment management operating model.

Having built and managed institutional infrastructure from startup through to multi-billion dollar scale, Nexus supports firms with operational strategy, front-to-back oversight, fund launches, governance, finance, vendor management, and regulatory change.

Whether the requirement is interim leadership, a specific project, or an ongoing fractional COO/CFO mandate, Nexus provides institutional-grade expertise without the commitment of a permanent executive hire.

Operational leadership that fits the way investment firms actually work

Engagements are structured around your firm's specific stage, size, and complexity, not around a standard consulting retainer model.

01

Embedded, not external

We work as part of your team, attending calls, sitting in board meetings, liaising directly with prime brokers and service providers on your behalf.

02

Immediate availability

Engagements can begin within days of an initial conversation. If your operational situation is urgent, that's exactly the kind of problem Nexus is designed to solve.

03

Flexible structure

Engagements range from a single project through to a standing fractional COO arrangement, monthly, quarterly, or as-needed. We structure around your requirements.

04

Institutional standards

Every engagement is held to the same operational standards expected by prime brokers, fund administrators, auditors, and regulators, regardless of your firm's current size.

05

Practical over theoretical

Advice based on having done the job, not studied it. From expiry risk management to NFA examinations, every recommendation comes from direct operational experience.

06

Confidential by default

All engagements are conducted with full confidentiality. Nexus does not discuss clients, strategies, or operational details outside of the engagement.
