What business or marketing book has left a lasting impact on you?

Crossing the Chasm; Geoffrey Moore - it’s an old “must-have” tech marketing book that still applies today.

I don't read much, but when I do, I prefer to read books based on human psychology/behavioral economics. These fields bridge the gap between consumers and decision-making and tie in nicely with an understanding of marketing. I'd recommend starting with some light reading (not overly complex terminology and concepts) by authors like Dan Ariele, Rory Sutherland, and Malcolm Gladwell. As a disclaimer, these authors tend not to write their findings based on science but rather on astute observation. They are reasonably interesting to read.

"The Cold start problem" is the best book about building network effects. So many aha-moments. https://www.amazon.co.uk/Cold-St...

I love HubSpot's articles :)

Start with Why by Simon Sinek

Zero to One is good - I am also reading "Done" right now and its all about scaling remote teams.. Also Launch by Jeff Walker (a little older but its all about email marketing / launch strategies and tons of good info in it)

the mom test, the lean startup, crossing the chasm...

$100M Offers by Alex Hormozi. I have read MANY books, but this one made me feel like my eyes are opening. Other very good books: HR/culture: The no rules rules Startups: The Lean Startup Teams: Rework Business stories: The Founders
