I am actually a Private Client Banker with JPMC. I don't think I can publically post the actually criteria this is close to accurate. But I can message you more details about Chase Private Client if anyone would like to know more.
Do you just store the 100k as cash in the business checking account? Seems like you can potentially put the cash instead in some 'investment' account so you at least can earn a better return but not clear what kind of investment account qualifies? Also, does that mean a personal checking account that is linked will also get chase private client status and waived fees?
