Glean.com? We had an intro meeting with them, pricing only makes sense if you're in a first world country and have 100+ or maybe 150+ employees.

I recall pricing started at 50k USD per year but may be remembering incorrectly. Please take this with a grain of salt as they may have changed their pricing models or whatever - I just get really annoyed at the "contact us" stuff so thought I'd try to help out here.
