What it is
A single-family office (SFO) is a private organization that manages the wealth, investments and administration of one family. It is typically governed by the family's own priorities, time horizons and risk tolerance, and it often develops its own view on where and how to deploy capital.
A multi-family office serves several families under one platform. In searches the term appears as "multifamily office," and the two phrases describe the same general model: shared investment, reporting, administrative and advisory capabilities, offered across more than one family.
A public thesis is a plain statement of what a family office tends to look at: sectors, stages, structures, geographies, and the kind of role it prefers to play. A clean intake is the process that lets outside parties submit opportunities in a consistent format so the team can review them efficiently.
How it’s traditionally been approached
Many single-family offices have historically operated quietly, relying on personal networks, referrals and existing relationships to source opportunities. This approach can build trust, though it may also mean that the family's real interests are not widely understood outside a small circle.
Deal flow has often arrived by email, introductions or informal conversations, and been tracked in whatever way the team found practical. Some offices use spreadsheets, shared inboxes or general-purpose software, and processes vary considerably from one office to the next.
Some families have preferred to stay private by design, and that is a legitimate choice. Others have chosen to articulate a thesis more openly so that relevant opportunities find them and irrelevant ones do not. Neither approach is inherently better; each reflects the family's objectives and comfort.
How the right family office may help
The right independent family office may help a single-family office translate its informal preferences into a written thesis. In a first conversation, a provider will generally ask about the family's goals, the sectors and stages of interest, the roles it prefers (lead, co-investor, passive participant), and any areas it wishes to avoid.
The right provider may also help design an intake process: what information an outside party should submit, how submissions are screened, who reviews them, and how responses are handled. Questions worth asking include how the provider manages confidentiality, how it documents decisions, and how it separates information gathering from any commitment.
Because this directory lists providers across direct investing and co-investment, operating companies and holdings, and venture and early stage, a single-family office may compare how different firms approach each area. Ask each provider about its scope, its conflicts-of-interest practices, how it is compensated, and which functions it does not perform. Rely on your own licensed advisors for legal, tax and investment decisions.
The bigger picture
Deciding how open to be about a family's investment interests touches more than portfolio construction. It can affect how much time and attention the principals give to inbound requests, how comfortable they feel about privacy, and how well family members understand and agree on the direction of the office.
A clearer thesis and a more orderly intake may reduce noise and support a calmer decision-making rhythm, though outcomes vary and nothing is assured. Where stress, family dynamics or personal wellbeing are part of the picture, Providers.plus may be a useful resource for finding related support. No approach to privacy or openness is wrong; the aim is a structure that fits the family.

Get matched privatelyFrequently asked questions
What is a multifamily office?
A multifamily office is a firm that provides wealth, investment, administrative and related services to more than one family. It is also written as multi-family office (MFO). Services and structures vary, so it is worth asking each firm exactly what it does and does not provide.
Why would a single-family office publish an investment thesis?
A published thesis may help the right opportunities find the office while reducing irrelevant inbound requests. It can also clarify the family's own priorities internally. Some families choose to remain private, and that is an equally valid decision.
What is a clean intake for opportunities?
A clean intake is a consistent, documented way for outside parties to submit opportunities for review. It typically specifies what information is needed, who reviews it and how replies are handled. The goal is orderly, confidential evaluation rather than any commitment to invest.
Can a multifamily office help a single-family office?
Yes, it may. An independent multi-family office can sometimes offer perspective on thesis writing, process design, reporting or access to specialist capabilities. Whether it fits depends on the family's goals, so compare scope, conflicts of interest and compensation before deciding.
Which provider types are relevant to single-family offices?
Single-family offices often explore direct investing and co-investment, operating companies and holdings, and venture and early stage providers. Each focuses on different kinds of capital deployment and involvement. Ask each about its role, its limits and how it works alongside your own advisors.
Is this page investment advice?
No. This page is educational and does not provide investment, legal, tax or accounting advice. It is not an offer to sell or a solicitation to buy any security, so rely on your own licensed advisors for decisions.
