My company had an exit, I did well financially. This is not a secret. I'm extremely privileged and thankful for it. But as a result of this, I've used a private bank (or mix) for a number of years to store the vast majority of my financial assets (over 99.99% of all assets, I just did the math). An unfortunate property of private banks is they make it hard to do retail-like banking behaviors: depositing a quick check, pulling cash from an ATM, but ironically most importantly Zelle.
As such, I've kept my Chase personal accounts and use them as my retail bank: there are Chase branches everywhere, its easy to get to an ATM, and they give me easy access to Zelle! I didn't choose Chase specifically, I've just always used Chase for personal banking since I was in high school so I just kept using them for this.
Anyways, I tend to use my Chase account to pay a bunch of bills, just because it's more convenient (Zelle!). I have 3 active home construction projects, plus pay my CC, plus pretty much all other typical expenses (utilities, car payments, insurance, etc.). But I float the money in/out of the account as necessary to cover these. We do accounting of all these expenses at the private bank side, so its all tracked, but it settles within the last 24-48 hours via Chase.
Otherwise, I keep my Chase balance no more than a few thousand dollars.
This really wigs out automated systems at Chase. I get phone calls all the time (like, literally multiple times per week) saying "we noticed a large transfer into your account, we can help!" And I cheekily respond "refresh, it's back to zero!" And they're just confused. To be fair, I've explained the situation in detail to multiple people multiple times but it isn't clicking, so they keep calling me.
I now ignore the phone calls. Hope I don't regret that later lol.
