You should list on Appsumo Marketplace(not just for direct sales)

So It's been 2 months since I've listed my directory product on appsumo and is nearing ~400$. It's not great but here's why I found it interesting.

Since the launch, some of the visitors and customers have been asking for services related to the product. They understand how it works but have no time to execute themselves. I was hesitant at first because I'm not an 'expert' and had no case studies even though I know how to get stuff done.

So started working with a few of them this month. Services include B2B sales prospecting, workflow automation for marketing agencies, etc.

If you're offering a service then it might be useful to create a product around it and list it in popular marketplaces like appsumo.
