The problem you highlight is real in any large enough enterprise. But the issue is not just about where the info is:
- How do you know you have the latest view of a given topic, ie. the files you've ingested represent the "head" of your company's knowledge tree?
- How do you deal with that important piece of insights that never made it to a digital storage, because it's only in Joe's head and by the way he moved team so unless you know who Joe is in the first place, you don't know what you don't know?
- How do you deal with the fact that some desks really don't like sharing info with each other and a big part of a Project/Product Mgr's job will be to painfully wrestling info from other teams (very real in banking/finance)?
Workplace knowledge fragmentation is an interesting business problem, mind you. I'm just saying it's not just a software problem...
I'd really start with a market survey of the existing competitor landscape if I were you. And maybe niche-down to knowledge fragmentation for a specific role-type (QA or DevOps or Marketing, etc...). And pinging a few existing founders for insights. I don't know, just spitballing.
