TweetToLinkedin - How start my marketing

Hello!
We are soon launching a tool that will allow you to transform your tweets/threads into LinkedIn posts, including of course LinkedIn codes.

It's simple, copy a tweet link and we convert it to Linkedin Post, you can editing in live the content, copy and paste to Linkedin or directly publish it to Linkedin.
(It's included the first image of Tweet or Threads)

We are looking for our way on the marketing side, we don't really know how we could meet and increase our number of users, we were wondering if releasing the tool for free initially could be nice by obviously setting thresholds to avoid abuse.. Or to create free tool around it, contact people on Twitter for get first users but it's hard to have response

If some of you want to test the application here is a link where you can enjoy the first features, looking forward to receiving your feedback!
