I have around $6M in my portfolio right now, expecting it to be ~$16M next year. It's being managed by a financial planning team at a national accounting/tax/wealth management firm. Their annual fee is either 0.5% or 0.75% with this size portfolio (it tiers downwards as they manage more money; I forget what tier I'm in now).

I frequently see the advice, both on this subreddit and elsewhere, never to use financial planners that take percentage-based fees. I hate the idea of giving away a percentage of my money each year, and I'm a long-term investor that is capable of parking my money in smart investments without their help, so this advice resonates with me.

That said, I keep thinking that this seems like a good deal, for a few reasons:

1. They do tax loss harvesting for me. According to them (would love to get validation/refutation on this), tax loss harvesting provides about a ~1%/year alpha long-term. I probably wouldn't ever do tax loss harvesting myself, so it seems like this alone would cover their fees and make this a no-brainer (?)
2. It's really convenient to have an entire team helping me with anything I need. They do things like set up a 10b5-1 for me and work with my company's legal team to make sure trades are done correctly. When I want to move equity around, I just text them and tell them what to do. When I want to wire money, I forward the wire info to them and they do it. They answer a lot of questions and do a lot of financial modeling for me that is better than I can do myself.
3. I'm doing a lot of angel investing, and once my portfolio companies start to have liquidity events, they'll be able to navigate all the conversations to receive payments (this can be a huge PITA, especially because deals often end up paying out investors mixes of stocks and cash, sometimes on strange schedules due to escrow withholdings, etc.)

That said, I'm still learning, so I'm worried about going against the advice I see everywhere, and am afraid that I'm missing something. Am I throwing my money away, or does this make sense for me?
