I hate to give founders this advice, but I feel like I need to say it. I ran the numbers, and about 2/3 of founders who reply after I pass ask whether I can introduce them to other investors. I completely understand why. Fundraising is hard, and one good introduction can change a round. But the honest answer is that I am unlikely to make those introductions unless someone specific immediately comes to mind (which is rare). It is not because I do not want to help. An introduction is a small endorsement, and if I have just decided not to invest, it can be hard to turn around and recommend the company to someone else. I also don't want it to send a negative signal to investors about the founder/company. There are exceptions. Sometimes I pass because the stage, geography, check size, or category is just not a fit. If I know someone who makes more sense, I will usually offer the introduction when I pass. Generally, though, I would not ask after a pass. With that said, if you feel the need to ask, I would just make the ask very specific. “Would you be comfortable introducing me to X? They seem like a fit because Y” is much easier to answer than “Do you know any other investors?” I know this is probably not what founders want to hear. I am saying it because their time matters too. A generic ask after every pass is unlikely to change the outcome, and if an investor has someone obvious in mind, they will usually tell you. Hopefully this is helpful. p.s. I have seen @bzises do a nice job of sharing a list of investors on his website, a solution I might steal.
