Most advisors who ask whether to start their own RIA or join one have already made the hard decision. They want independence; what they cannot see is the shape of it. The question stalls for months because it gets framed as a coin flip — total freedom or total overwhelm. That framing is wrong, and it talks capable advisors out of moves that would have suited them fine.
There are three roads, not two.
Build your own firm from scratch, join an existing one as a tuck-in, or plug into an aggregator or platform that carries the operational load. Two of those roads were built for people who want to serve clients under their own flag without running a compliance program on the side. Circling this decision without landing usually means you were seeing only two of the roads.
The middle options exist because plenty of excellent advisors have no interest in being founders — and a forced choice between founder and employee loses them.
Registration is the easy part.
Starting your own RIA surprises people here. You form an entity, file Form ADV, write your compliance policies, and name a chief compliance officer — in a small firm, usually you. A consultant can walk you through the filing in weeks. If difficulty ended at registration, everyone would build. It doesn't end there. You own the custodian relationship, the technology stack, the E&O coverage, and the compliance calendar — ADV updates, books-and-records, advertising review, mock-audit prep. None of that involves a client, and all of it is now yours.
The other two roads hand off the operating.
Consider what each middle road actually removes:
- A tuck-in wins whenever your hesitation is operational rather than professional — someone else files the ADV and answers the auditor, and you step in and serve clients.
- An aggregator or platform lets you keep your own identity and a real degree of ownership while it carries the heavy lifting, often bundling a TAMP so investment operations come off your desk too.
The tuck-in trade is straightforward: the firm is not entirely yours, and your economics reflect using infrastructure someone else built. The platform trade is the last increment of control — approved technology, compliance guardrails. You sit between the poles: more autonomous than a tuck-in, never as alone as a founder.
The fork turns on temperament.
Ask yourself how much of a business operator you want to be. If building and running a firm energizes you — if the vendor decisions and compliance calendar read as ownership rather than burden — the from-scratch road can be worth what it demands. If the operating side fills you with dread and you simply want to serve clients under your own flag, a tuck-in or a platform removes exactly the part you don't want. The advisors who regret it are rarely the ones who moved; they are the ones who picked a structure mismatched to their appetite.
The book has to be able to follow you.
None of the three roads matters if the clients cannot come. The Broker Protocol, created in 2004 by Smith Barney, Merrill Lynch, and UBS, lets a departing advisor take exactly five fields — name, address, phone, email, account title — and only for clients they personally serviced, with both firms as signatories. Morgan Stanley withdrew in late 2017 and UBS followed weeks later, so a departure from either is generally governed by your employment agreement instead. The practical move is the same regardless of firm: get your agreements read by a securities attorney before you act, not after. An hour of specialist review is the cheapest insurance in the process.
