I can empathize with founders at least somewhat because funds have to raise money too. Our first fund required 100+ investor meetings, took about 8-10 months to close, and consisted of a lot of small checks. So I do know what a slog fundraising can be, how frustrating investor signals and behavior can be, how hard it is to change someone's mind if they have a strong bias, etc.
> So what you read as a simple e-mail response may realistically have been half a day of lost fundraising productivity, for, at best, a 10% chance they convert your gut-feeling "maybe" to a "yes."
I hope it's not half a day =(. I do have a different framing of time spent though: if you can invest 30 minutes (or even half a day) into an email that has a 10% chance of converting a Maybe to a Yes, then that's very worth it. If you talk to 10 funds like mine that all write $750k checks, then spending 30 minutes x 10 funds to get a $750k commitment means your time is earning $150k/hour. Even if it's half a day instead of 30 minutes -- and I hope it's not -- that's ~$20k/hour. That's a great ROI when you might be trying to raise $1m or $3m.
