Are you asking about marketing techniques as in advertising strategies, or are you asking about the underlying business model?

If the former: the README.md is by far the most important artifact, and specifically the first scroll or two. The call to action (installing/trying it out/clicking to your pricing page/whatever) should be clear and upfront and easy.

Having a website that uses popular doc rendering frameworks also help -- people will recognize the look and feel and feel somewhat assured. Tho I suppose a task planning app prolly has docs figured out.

Godspeed, and thanks for sharing your work with the world! We need it, and we appreciate it.

My approach:

1.Open source + polished README

2.Listed on directories like create.io

3.Added to awesome-rust

4.Did a Show HN post

That's all I've done so far. 60 stars currently.

Why do you think your target market would change? I would have guessed the target market is the same, so marketing should be straight forward: same demographics but differentiating you from the pack and how it matters.
