I just wrapped up a short book called "Websites that Convert: the fundamentals of writing compelling website copy."
It's specifically for founders struggling to convey in words how awesome their product is (i.e., founders who don't consider themselves "marketers" or "writers"), and it launches on Product Hunt next week.
If you'd like a free copy before it goes live, send me a message with the best way to reach you, and I'll hook you up
PS: If you're wondering "Who's this person?," I've joined a few conversations but mostly lurked so far. I'm Claire, and I run LoveYourCustomers.co. I was previously Director of Marketing at Calendly.
