I'm not sure why anyone would think a connection to an investor would be easy to find. This is likely a bigger issue than whatever you're trying to build, because funding partners need to be a good fit.

Unfortunately, without existing connections, you have to put in a lot of effort helping people in your networks so you can ask them to help you. If you haven't been putting that work in by providing real help/value/relief to those in your network for years, it is an uphill battle to get a warm intro to an investor of all things.
