There are a couple of discussions on IndieHackers now about having your product promoted on AppSumo. Andrew Kamphy has sold over 500 copies of his BetterSheets on AppSumo. At $19 each, it comes to over $10k after four months. @Nscode just got his book accepted by AppSumo. AppSumo keeps 70% of sales, so that doesn’t leave much for the creator. However, it can be a good way to get more customers. I’ve purchased many products on AppSumo including SerpStat, which made $250k in one week with their promotion. SerpStat wrote a comprehensive guide for a Successful AppSumo Promotion.
