Wemyss Advisors is an independent fund advisory firm specializing in high-conviction fund manager selection and institutional-grade monitoring for mid-size investors.

We act as an outsourced investment office for family offices, foundations, and mid-sized institutions seeking hands-on, conflict-free support in navigating a complex manager landscape.

Backed by over 35 years of global experience in asset management, we bring a rare combination of deep due diligence expertise, strategic portfolio thinking, and senior-led advisory to every engagement.We empower mid-size allocators to access best-in-class fund managers — without the overhead of building internal research capacity. Through a disciplined, transparent process grounded in institutional standards, we deliver manager selection and ongoing oversight tailored to each client’s objectives and constraints.

We offer modular engagement — from a one-off due diligence assignment to fully delegated manager oversight. Whether you are building a new investment program or fine-tuning an existing portfolio, we become an extension of your team — bringing conviction, clarity, and continuity to manager oversight.
