对"强制跟投"的介绍，请见上一篇《 投资人的收入有多低 》 （一） 请问尊敬的合伙人：目前只有投资团队有跟投机制。您说，因为项目是投资团队找的。 那么，基金里面，募资团队是不是也要跟一点？因为 lp 是募资团队找的呀。 如果 lp 的落地、对赌等条款，导致我们投不到好项目，进而导致我们投的项目退不出来，是不是应该 lp 也负责？募资团队也负责？ 但是现在呢，募资团队每年拿的募资奖励，金额比投资团队的投成奖多多了，还没有什么跟投。合伙 人，你能不能给我解释解释？ （二） 尊敬的合伙人，感谢您没有设置强行跟投机制。几个老员工常说，感谢合伙人，一定 996 工作，为公司 奋斗到死。 难道 … 不是因为您给的薪资太低了，如果再强制跟投，根本就招不到人了？ 然后，因为不强制，所以我入职至今，一个项目都没有参与过跟投。 您那天还问我，怎么不跟？我现在回答您：因为你们这家机构投的项目都不行。 您可能又会问，但是项目不是我挖掘，我推进的么？ （四） 尊敬的合伙人，我想请问： 您觉得，假如我们有投资 DeepSeek 、宇树的机会，员工会不会踊跃跟投？如果我们每个项目都是 DeepSeek 、宇树这种档次，还有必要"强制"跟投 ...
