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-in to the investment thesis, nobody "owns" the deal nor stands for it emotionally, which can lead to less attention post-transaction.
