I was trying to fix the problem of getting relevant knowledge and staying up-to-date with my startup https://www.gainknowhow.com/ https://www.gainknowhow.com/ . It never took off organically and I only sold it to a couple companies. My core idea in GainKnowHow was to structure data as a graph of skills. I think the graph data structure to store knowledge is better than how a lot of tools store knowledge today. I still think it is a great way to store knowledge and use it myself to train people, but the graph data structure was a leap too far for many people who implement knowledge systems at companies.
