Hmm, I just launched and since I have no network, I think it will be quite hard for me to get it featured. If you have a tiny network that does like your product, I think as @aryankhan said, it would probably give you a boost on top of it. If you get featured, that's when you can get a lot of attention.
Product Hunt is a great way for traffic if your product comes under the top 5 products or gets featured. But I haven't found it really effective at building an audience.
Yes. I think trying a product hunt launch is always relevant, even if you feel that PH audience is not your audience.
You have the option to relaunch after 6 months so I would advise you to make a no-frill launch as soon as you can: https://fabian-maume.medium.com/...
Yes it has. In fact after launching we still get traffic directed through Product hunt. It worked out well for us. Are you planning to launch your product soon?
