I would question whether you're really at the growth fundraising stage if you can't concisely summarize the offering and problem it solves.

How are you going to get customers / revenue if nobody can understand what you are doing without a long explanation?

Maybe you should look for research funding if it's more of an academic problem. Or if you really believe it's time to grow a company, find someone better at targetting messaging to VCs.

I can sympathize, I'm actually in the process of something similar, and was told recently that basically any explanation that appeals to me (as an engineer) is going to be off-putting to the folks I'm pitching to.
