What's your favorite growth & marketing success story?

I'm launching a marketing mailing list for makers within a few weeks, where I will share ways to grow your audience and market your product.

(I'm a marketer originally with a love for no code :)

Do you have any awesome examples of small or big growth hack stories to share?

What did your favorite company or maker do to get their tweet, landing page, launch etc to reach a lot of people?
