Ask HN: What project, product, or company do you want to sell?

Hi everyone. I'm curious to see which members of the HN community are looking to sell products that they've built in their spare time and what those products do. I'm not looking to purchase anyone's product or company at this time, but I'm sure there are members of HN that would love to hear about great technology that is for sale. I've found that the companies or websites on Flippa tend to not be of a very high quality, and thus thought asking what sites are for sale here might bring more interesting answers!
