A lot of times makers/founders want to sell their business, but don't really know how to do it without later regretting it. Sometimes it's because they sell it to the wrong person (someone who's just looking to resell it in a few months) and sometimes it's because they feel like they didn't sell it for a good enough price (mostly happens when they accept the first offer as soon as they hear it). There are a few marketplaces to help facilitate this process for the founders, but honestly most of them care only about making a sale, mostly because they get a cut.
I started Soochi [1] to solve this exact problem: Help founders sell their projects/startups without having them regret it later. At the risk of not stretching this post to a blog post's length, I'll just link this Medium post [2] I wrote introducing Soochi, and explaining how I see things working with Soochi.
I am really hoping Soochi succeeds at solving the issues makers/founder currently face with the current options, and would love to hear any feedback, or answer any questions that you may have about the site.
