How do you get BETA for you new launch?

I am launching ContentFeed and offering - Free Use Till BETA runs - Free 400 Tokens after BETA ends as gratitude. I'm looking for 200 BETAs as best. I started posting on LI, TW, and BETA listing tools. I received 15+ odd users in 4 days. What else do people do to get BETA? If I talk about ContentFeed, it helps marketers, content creators, and founders generate social media content that is not generic LLM-based. ContentFeed is a Chrome Extension that opens on any webpage and transforms the web page's content into a post in seconds. If anyone is interested in trying, please let me know.
