Which social channels work best for product creators?

It's challenging to grow an audience across multiple platforms. Based on your experience, where is the best place to post content? I’m developing an AI scraper, and my target audience includes professionals from various fields who need to gather and analyze data. I currently use Twitter, LinkedIn, Reddit, and I also write articles on Medium and Dev.to. Recently, I’ve become more active on ProductHunt. So far, it seems that Reddit generates the most interest in my product, offering valuable feedback. LinkedIn is useful for finding users, while Twitter seems better for sharing the creation story and development nuances - though my audience there might be more developer-focused. Medium has been my go-to for sharing testing experiences, making it difficult to shift focus, and Dev.to is again mostly for developers. What’s your experience? What’s your product, and where does your content get the most traction?
