30-Day Implementation Plan

  1. Week 1 — Thesis + stages

    1. Write investment thesis checklist on one page — score 1–5 fit before deep diligence.
    2. Notion deal DB: stage, sector, check size, owner, next action.
    3. Define pass reasons taxonomy — market, team, traction, terms, timing.

  2. Week 2 — Inbound hygiene

    1. HubSpot or Notion: log source on every intro — warm vs cold vs platform.
    2. Clearbit enrich top 20 inbound this month — note mismatches vs deck in memo.
    3. Claude first-pass memo on 3 live deals — partner redlines template prompts.

  3. Week 3 — Diligence checklist

    1. Standard diligence task list: references, cap table, revenue quality, legal red flags.
    2. Notion AI: meeting notes → open diligence items assigned with due dates.
    3. Make: wire inbound form to Notion if volume justifies — test failure alerts.

  4. Week 4 — Pattern review

    1. Quarterly: pass reasons vs outcomes where trackable — calibrate thesis.
    2. Cut Clearbit credits if enrich rarely changes go/no-go at your stage.
    3. Archive memos — reuse question lists beats reinventing each deck.
