I can tell you if you can easily use Reddit and HN for growth

I've been helping founders find easy growth on Reddit and HN for three years now. There are some caveats though:

• it's easy growth, but there is a limit, and it doesn't work for every product
• must have competitors
• must already be profitable
• must be a product, not an agency

I'm happy to help. If this sounds good, please let me know the name of your company and how I can contact you :)
