These get discussed as one decision. They are two, and the honest answer for most advisers is not the one the industry celebrates.
Starting your own firm gets the attention. It is the version with the founding story.
Joining an existing independent firm is treated as the compromise. For a large number of advisers it is straightforwardly the better decision, and the reason it is undersold is that nobody writes an article about it.
Full ownership of the equity. Complete control over technology, investment approach, and how the practice runs. No partner whose preferences you have to accommodate.
It also gives you every operational decision, the compliance obligation, and the hiring.
Infrastructure that already works, on day one. Compliance that is someone's actual job. Colleagues. And usually a faster path to serving clients well, because you are not simultaneously building the thing you are serving them with.
What you give up is control and, typically, a share of the equity — though many independent firms now offer real ownership rather than a synthetic version of it.
Do you want to run a business, or do you want to advise clients inside a business that works?
Both are legitimate. They are not the same job, and a lot of unhappiness in this industry comes from people who wanted the second and signed up for the first.
Wanting to own something and wanting to run something are different desires. Only one of them is satisfied by a founding.
Think about the last time a vendor contract needed renegotiating, a system needed replacing, or a compliance deadline moved.
If your instinct was interest, start the firm. If your instinct was that you wished someone else would handle it, join one. That reaction is more predictive than any spreadsheet.
Joining an existing firm with an equity path, or starting one on a platform that carries the operational weight, are both real options. Neither is a failure of nerve.
The decision that matters is ownership. How much infrastructure you personally assemble is a separate question, and treating them as the same question is what makes this harder than it needs to be.
