All In Method
Definition - What does All In Method mean?
The all in method is a strategy used in private equity (PE) firms to obtain funding for a potential transaction. Private equiteers regularly bring opportunities to a PE firm's investment committee. The all in method (as opposed to the defensive lead method) involves all the members of the firm discussing the merits and pitfalls of the opportunity without a specific champion. Since the all in method is more inclusive of everyone's input, it is a preferred approach at PE firms as it allows for everyone's buy-in.
Divestopedia explains All In Method
Although consensus is a good thing, the all in method does not generate the sense of responsibility needed to make a deal successful. It can be good for getting capital for a transaction, but because there is no primary advocate, it may not get the same level of attention needed once the deal is funded. While everybody may buy into the investment thesis, nobody "owns" the deal nor stands for it emotionally, which can lead to less attention post-transaction.
