For executive directors, founders, and program directors whose calls, docs, voice notes, and Slack channels need to be one queryable mind — not seventeen disconnected sources.
30% mission-driven discount on Operator and Team for verified 501(c)(3)s.
§ 01
When an ED leaves, a program director rolls off, or a founder steps back from operations, the institution loses something it never wrote down. Vellum captures that working memory in real time — calls, voice notes, decisions, drafts, channels — and renders it queryable as one mind.
Vellum is not consumer note-taking dressed up in a pricing page. It is institutional memory: the layer that sits underneath an organization's operating cadence and answers questions that would otherwise require pulling someone off their work.
Inside the Perpetual Engine, Vellum operates on the Knowledge registry — one of the eight registries the studio installs in every engagement. Vellum is the surface most teams encounter first, because Knowledge is the registry where ROI shows up fastest.
The synthesis is the deliverable.
§ 02
Every source, one mind.
Calls, board docs, Slack channels, voice memos, Google Drive, transcripts. Vellum reads them, indexes them, and answers across them — not from one of them.
Synthesis, not search.
Most knowledge tools surface a list of links. Vellum reads the full corpus and writes the answer with citations to the source documents. The answer is the deliverable.
Voice in. Voice out..
Walk-and-talk briefings. Phone-call transcripts that flow back in as queryable memory. The voice channel isn't an afterthought — it's a first-class input and output.
Retention you control.
30-day, 1-year, or custom retention windows depending on tier. Operator-grade memory without the audit risk of forever-storage. Per-source overrides on Institution.

§ —
If your organization wants the full eight-registry Engine installed — not just the Knowledge surface — that's an engagement. Engagements start at $75,000. Vellum subscribers who outgrow the SaaS tier get an introduction to the studio process; we don't double-charge for what you've already paid for.
