What are the indie products with the best growth strategies?

Hey fellow IHers,

I have been spending some time trying to reverse engineering the marketing strategy of companies I like, and I'm running out of inspiration, so I thought that IH would be the best place to help :)

So, I'm asking : in your opinion, what are the indie products with the best growth strategies?

I personally like what the Mailbrew team is doing :

• They nailed side-project marketing with Typefully, their "distraction-free editor for Twitter".
  Mailbrew's goal is to help people consume information on the internet more mindfully / Typefully's goal is to help people use Twitter more mindfully : it's a perfect fit !

• Mailbrew users can make their brews public, which is a great way to build virality into their product...

• Instead of launching right away, they chose to keep the product in private beta and iterate on it based on the first users’ feedback & manually onboard their first users

  • And finally, this is not exactly marketing related, but as a user, I have to say that the product is great : I have been using for a month now, and I really like it. I know that some people say that good marketing can save a bad product, but I’ve found that having a good product makes marketing 100x easier.
