Why every consulting firm should run a private knowledge base
Email threads, scattered Slack channels, shared drives. Works at three; falls apart at thirty.
In short
A private, per-workspace knowledge base keeps each client's reading isolated and citation-grounded — the opposite of an org-wide wiki that nobody trusts or maintains.

The case
Most consulting firms still rely on email threads, scattered Slack channels, and shared drives. That works at three people; it falls apart at thirty. The case for a single retrieval surface is now clearer than ever — especially with cheap embeddings and decent retrieval models.
What breaks first
Three failure modes appear, in order: (1) the same article gets sent in DM by two partners on the same day; (2) a junior asks for the regulatory landscape and gets four different shared-drive folders; (3) a deck for a client cites a piece of research nobody can re-find later. Each is small. Together they're the whole problem.
The knowledge a consultancy compounds is its real product. Email and Slack are not knowledge bases — they're sieves.
Three minimum tables
A private knowledge base doesn't need a CMS, a headless service, or a vector-db daemon to start. Three tables get you most of the value: bookmarks (URL, title, content, tags), highlights (passages saved from articles), and concepts (auto-emerged topics with citations back to bookmarks). Everything else — briefings, audio, related links — is derived.
Why not Notion
Notion is a write-tool. It rewards the act of authoring. A knowledge base for consultants needs to reward the act of reading. The interface should be a stream of inputs (bookmark, highlight, dismiss) that compound into outputs (briefing, concept page, search). Authoring is the wrong primitive.
Cost analysis
A one-person consultancy reads ~15 articles a day. At ~5 minutes each, that's 75 minutes daily on input. At ~10 seconds to bookmark + 30 seconds to highlight a passage, the cost of capture is ~10% of reading time. The return — re-find anything ever read, generate weekly briefings, surface concepts across an engagement — is the rest of the consulting career.
FAQ
How is this different from Notion or Confluence?
Notion and Confluence are write-tools. Pith is a read-tool. The output is briefings and concepts, not pages someone has to author and maintain.
Where does the data live?
Frankfurt, Hetzner. EU-only data residency. Per-workspace Postgres database. Export anytime as SQL or markdown.
What about confidentiality?
Workspace-scoped. Tag bookmarks per client; the briefing for that client only sees those bookmarks. Auditable.
