About
Sonder Partners serves individual and high‑net‑worth clients and also works with other registered investment advisers, but its primary business is referring clients to a small set of unaffiliated advisory firms for ongoing management. The firm continues to provide discretionary portfolio management only on a legacy basis to a limited number of existing clients and facilitates use of third‑party money managers.
The firm conducts suitability assessments and diligence on a fixed roster of third‑party managers and model portfolios to match clients with an external manager or program, and it may assume discretion to hire, terminate, or reallocate among those managers on clients’ behalf. In its own limited management, Sonder Partners combines quantitative and qualitative security analysis and relies heavily on third‑party models and manager research rather than operating a broad in‑house investment platform.
Distinctive aspects include a referral‑first business model that contemplates receiving compensation from the advisers to whom it refers clients and an intentional restriction of direct portfolio management to legacy relationships rather than new business. The firm also discloses ownership and advisory ties with outside financial platforms and a venture capital fund, and operates with a very small client base relative to the scope of its referral activities.

We'll help you think it through – whether you ultimately need an advisor or not.
Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
