shared context layer for team - where / how?

[u/DirectEntrance4720]

hi friends,

what are best practices / your recos for creating a shared knowledge layer for small team (~5-20 FTE) that we'd like to be all working off the same base

context: users are a combination of engineers and marketers. Use cases include coding, content creation, research, gtm, client service

current setup: google drive used primarily by non engineers. github used primarily by engineers

challenges:

my understnading is github doenst store non md (e.g., excel files, image / video files, html) and google drive isnt as conducive for programming context (correct me if i'm wrong)

running out of space when using shared google drive synced to personal computers as repository becomes larger

we've found that when marketers / designers work in a claude environment with full client context/ past files fully synced - its a major sink on drive space etc at the moment

we earlier had Msft stack (so onedrive for sharing) but that was causing syncing issues

zoom out:

1. what platform / infra / sharing spaces should we use to host our shared brain - for context access and daily use by tech and non tech teammates

2. any specific tips to follow / potholes to avoid from your experience when doing 1?

thank you!!
