A great way to see new products and get exclusive lifetime deals to what would otherwise be a monthly subscription. Quality of offerings vary, but AppSumo do actively vet offers in their "Select" programme, assuring decent standards for Select products, at least.
A 60 day no-quibble refund policy does what it says, so you can try software knowing if you don't want to keep it, you don't pay for it.
Finally, we launched Kirmada on AppSumo as a Select offering and had an overall good experience, picking up about 700 new users who have given great feedback for our roadmap. If you're thinking of this for your own SaaS then you'll get the same, but you won't get MRR!
