PrefMark

Deal memos and diligence

Integration details

Description

PrefMark keeps an Investment Memo current for every deal you are evaluating. Ask where a deal stands, what changed since you last looked, which diligence questions are still open, and how well each figure is supported. You can also add deals and meeting notes, record diligence answers, and rewrite a memo section in plain language. PrefMark polishes the wording without changing facts, applies it once you approve, and keeps every version so you can undo or restore. New figures or a changed stance from a founder email wait for your review in PrefMark.

Tools

17 tools agents can invoke

Adds a question to the deal's diligence tracker in PrefMark. It is saved right away. Returns the new question with its id.
add_question
Adds one to 25 companies to PrefMark as deals, with any stage, sector, website, HQ, round size, lead investor and short description you have. A company already in PrefMark is not added twice. Saved right away.
add_deals
Applies a drafted memo-section edit after the investor approves its proposed_text in this chat. The memo updates right away and can be undone in PrefMark. Figures and stance changes still wait for Accept in PrefMark.
apply_memo_edit
The deal's current facts (ARR, burn, runway, raise…) with value, evidence tier, who asserted it, source and date, plus earlier values it replaced. Founder claims are never shown as verified. Read-only.
get_evidence
Call this BEFORE showing the investor any rewritten memo text. PrefMark polishes your rewrite (facts unchanged) and returns proposed_text and event_id. Show proposed_text; apply it with apply_memo_edit only on a yes. Changes nothing yet.
draft_memo_edit
Finds the deal a name or text refers to. exact: one deal. likely: the text names part of one deal; use it and say its full name, but confirm with the investor before submitting anything. ambiguous: ask which one; never guess. none: not in PrefMark. Read-only.
resolve_deal
Lists your PrefMark deals, newest first: name, stage, sector, the memo stance (Greenlight / Watch / Pass), proposals waiting for review, and as-of. Paginated with next_cursor. Read-only.
list_deals
The deal's diligence questions from PrefMark's tracker, blockers first, with ids. include=all adds answered and resolved questions with their answers and evidence. Read-only.
get_open_questions
Proposals agents submitted for this deal that the investor has not reviewed yet, with review links into PrefMark. Read-only.
get_pending_changes
The deal's current case: stance, reason, next action, hangers, risks, facts, open questions, proposals waiting for review, and the live Investment Memo section text. Read-only.
get_deal
The deal's Investment Memo as written in PrefMark (summary, thesis, team, market, traction, round, risks, open items) and its Quick Read. Read-only.
get_memo
Deletes a question from the deal's diligence tracker. Use update_question with status resolved instead when the question was answered.
remove_question
Saves meeting notes, an email or any text to the deal's Materials in PrefMark, where it is read like an uploaded file. Saved right away; it informs the next memo refresh and never changes the stance by itself.
add_note
Relays a statement, facts, or a proposed memo-section edit. PrefMark never changes the stance or the memo by itself; anything new waits for the investor to accept in PrefMark.
submit_deal_event
Changes a deal's name, stage, sector, website, HQ, round size, lead investor or short description in PrefMark. Pass only what changes; an empty string clears a field. Saved right away. Never changes the stance or the memo.
update_deal
Records an answer, evidence or notes on a tracker question, or changes its status (open, in_review, resolved, blocker), wording or due date. Saved right away; pass only what changes.
update_question
What materially changed on the deal since the investor last reviewed it in PrefMark (default), or since a given time: the memo's own 'Since last time' lines, plus proposals waiting for review. Read-only.
get_what_changed

PrefMark FAQ

How do I improve a ChatGPT Plugin's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
