Build a Pitch Deck Archive in Your CRM: API and MCP Patterns for VCs

Every fund has a deck graveyard: hundreds of DocSend and Papermark links scattered across inboxes, Slack threads, and CRM notes — a third of them already expired. The fix isn't discipline; it's plumbing. If converting an inbound deck to PDF and filing it takes any manual effort, it won't happen consistently. If it's automatic, your CRM becomes a complete, permanent archive of every deck your fund has ever seen.

This post lays out the patterns we see working, whatever CRM you run.

The Core Pattern

Regardless of tooling, the loop is always the same three steps:

Capture the link the moment it enters your world (inbox, intake form, CRM field)
Convert it to a file with one call to the DeckExtract API — POST https://deckextract.com/api with {"url": "...", "email": "deals@fund.com"} returns the PDF directly; add "format": "pptx" if you want editable slides
File it on the record — attached to the company in your CRM, or stored in Drive/Dropbox with the link written back to the record

DeckExtract handles DocSend and Papermark links the same way, including email-gated and password-protected ones, so one integration covers both platforms founders actually use.

Pattern by CRM

Attio. The most API-native of the bunch. Trigger on a new pipeline entry (or a "Deck URL" attribute being set), call DeckExtract, then attach the PDF to the record via Attio's API or write back a storage link. We covered the full Attio workflow in last week's post.

Affinity. Affinity already auto-logs the emails — but not the contents behind a DocSend link. Pair an inbox rule on your deals alias with a script that extracts the link, converts it, and posts the PDF to the organization's files via Affinity's API. Your relationship intelligence now includes the actual deck, not just the fact that one was sent.

HubSpot. For funds (and corp-dev teams) on HubSpot: trigger a workflow on deal creation, run the conversion in a custom-code action or via your automation tool, and attach the PDF to the deal. HubSpot's native file attachments make this the most self-contained setup.

Notion-as-CRM. Plenty of emerging managers run their pipeline in Notion. Same loop: a database automation or scheduled script watches for a "Deck" URL property, converts, uploads the PDF to the page. Notion's API file upload finishes the job.

The glue layer is whatever you already use — a 30-line script on a cron, Zapier, Make, or n8n. Mind the public API's rate limit (5 requests per IP per 30 minutes): batch jobs should pace themselves; normal inbound deal flow fits comfortably.

The MCP Pattern: For the Decks That Arrive Mid-Conversation

Pipelines catch the predictable flow. But decks also show up ad hoc — a WhatsApp forward, a link pasted in a partner meeting. For those, the DeckExtract MCP server puts the same capability inside Claude, ChatGPT, and other AI tools: paste the link in the conversation, ask for the PDF, and have the assistant summarize it or draft the first-pass memo while it's at it. If you're new to MCP, here's what MCP is and why it matters and a walkthrough of extracting decks directly from Claude.

The teams getting the most out of this run both: the API pipeline for everything that hits the funnel, MCP for everything that doesn't.

What a Complete Archive Buys You

Diligence integrity — the exact deck version you evaluated, preserved, even after the founder revises or kills the link
Portfolio memory — when a company raises again in 18 months, the old deck is on the record next to the new one
LP and IC readiness — memos can reference and link archived materials instead of dead URLs
Your own analytics stay private — re-reading an archived PDF doesn't ping the founder's DocSend dashboard the way re-opening the link does

Ground Rules

Worth restating: DeckExtract only converts documents you can already view — it completes the same email/passcode steps your browser would, and the platform still logs the visit for the sender. Archiving what founders sent you for evaluation is normal practice; honoring NDAs and confidentiality is on you, same as with the live link.

Start Small

Don't build the full pipeline on day one. Pick the single highest-volume entry point — usually the shared deals inbox — wire the three-step loop for it, and expand from there. The API docs have copy-paste examples in curl, Node, and Python.
