Should You Start Your Own RIA, Join One, or Tuck In?

The short answer: There are four ways into the RIA channel, and they differ first on whose firm it is. Start your own RIA and the Form ADV, the chief compliance officer, the equity and the costs are all yours. Join an existing RIA and you work under its Form ADV and its compliance officer, and own only what your deal grants. Tuck in, and a larger RIA buys or merges in your practice and its clients. A supported-independence platform sits between the two ends: depending on the platform, you either own your registered firm and buy support, or work as a representative under the platform's registration.

The structure underneath each model is public and checkable, because it is written into the firm's Form ADV and into the agreement you sign. The comparison below sets them side by side on the questions that decide everything else.

The four models, side by side

Starting your own: everything is yours

Your firm files its own Form ADV, and its Schedule A lists the executive officers, including the chief compliance officer, and every direct owner of 5% or more. An SEC-registered firm must designate a chief compliance officer who is a supervised person of the firm, and that role cannot be split between more than one individual. In the independent model, as Kitces describes it, owners are generally paid directly by their clients and select and pay for the vendors, services and employees themselves. The full launch sequence is in how to start an RIA, and what the build costs is in what an independent RIA platform actually costs.

Joining an existing RIA as an employee or partner

You become a supervised person of the firm: one of its officers, partners or employees who gives advice on its behalf and is subject to its supervision. An SEC-registered firm delivers a brochure supplement about you to each client you serve, and its CCO administers the compliance policies you work under. Investment adviser representatives of an SEC-registered firm may also need to register in each state where they have a place of business.

Partner can mean many things. Schedule A lists every direct owner of 5% or more, which makes it one place to check what a partner title carries, and equity when you join an RIA explains how to tell ownership from a retention device. If the firm has outside investors, who owns the firm you're joining covers the questions to ask about them.

What is an RIA tuck-in?

A tuck-in is the practice-level version of joining: an existing, usually larger, RIA buys or merges in your practice to grow faster than it could by winning clients one at a time, the framing Kitces used in 2013. Your team typically comes onto the larger firm's Form ADV and works under its compliance program. For an SEC-registered firm, every advisory contract must provide that it cannot be assigned without the client's consent, so moving clients into the larger firm runs through client consent. If your practice was its own registered firm, its registration is withdrawn on Form ADV-W when it stops advising clients. Terms on leaving vary: one firm that takes in practices told Kitces its advisor teams can leave without restrictions, and only the deal documents tell you what yours say.

Where supported independence fits

Supported-independence platforms come in two shapes. Kitces has described platforms that let advisors fully own their own independent firm, with technology and back-office support such as compliance and operations, and corporate RIA platforms where the advisor works as an investment adviser representative under the platform's RIA while keeping a separate practice entity. In either case, the functions the platform covers are paid for through its fee, and the more of the operation it handles, the less autonomy the advisor keeps. Independent RIA platforms explained maps the layers.

Does the choice have to be permanent?

Each model sets the terms of the next move. Clients who follow an advisor sign new agreements with the next firm, and an SEC-registered firm delivers its brochure before or at the time they sign. Whether you can contact them first depends on your agreement, any non-solicitation terms, and whether both firms are Broker Protocol signatories, which is a question for counsel. Cerulli reported in February 2026 that 97% of independent RIAs say they would move to another independent RIA if they switched.

Which model fits depends on what you want to own, run and be able to sell. Winthrop's RIA Search & Launch works through all four with you, including the build itself, and the RIA Launch Checklist sets out the steps for a firm of your own. Request an introduction.
