Many people run businesses with others: as a limited company with two or more shareholders, a partnership, a limited liability partnership or (less commonly) a limited partnership.

Any of these could be a called a 'joint venture' and, while working with other people has many advantages, obviously at some point the parties may not agree on the way forward. Arguments can arise on everything from profit sharing to succession planning, from decision making to transfer of ownership, and (most frequently) the contribution of the other participants.
