Not tech-related but it happens with law firms, which are often Limited liability partnerships (LLPs). A notable example is Heenan Blaikie in Canada, which was the 5th biggest national law firm with offices everywhere in Canada with over 500 lawyers. The firm had its most profitable years right before it was dissolved in 2014, mainly due to loss of trust and infighting - partners started leaving the firm and taking the money they put in (which I believe had a snowball effect) and lots of partners lost their money.
