CAP: find the overlap, make the right intros

CAP: find the overlap, make the right intros

Founders love helping founders. The problem isn't intent—it's mechanics. You meet someone strong, they're raising, you want to help… and then it turns into a 30-minute spreadsheet call: two messy trackers, duplicates, half-warm contacts, and a vague "maybe intro?" list that dies in follow-up.

CAP (pronounced "cap," like the ∩ intersection symbol) makes the helpful thing the easy thing. It maps the overlap between who I'm willing to intro and who you want an intro to—so we can agree the best two or three intros in minutes, not hours.

Why this exists

Precision beats volume. The right warm intro is worth more than ten "spray and pray" emails. CAP is built for the high-signal moments where fit matters.

Curation I met them once is not an intro. CAP encourages a curated list of people you will actually vouch for.

Momentum is fragile. That window right after you meet a great founder is when action happens. CAP reduces friction so momentum survives.

What CAP does (v0)

  • Import your tracker (CSV/XLSX).
  • Curate with intent: mark the investors you're genuinely willing to intro to, and the ones you want intros to.
  • Share with one founder by email.
  • See the intersection instantly:
    • A→B: investors Alice can intro ∩ investors Bob wants.
    • B→A: the inverse.
  • Export an intro plan you can send the same day.

No social graph. No scraping. Just the overlap.

How it works (happy path)

  1. Upload & map. Drop a CSV, map columns (name, firmName, url, notes, boolean flags).
  2. Toggle your truth. Mark Can Intro and Want Intro at the row level; add quick notes and tags.
  3. Invite a founder. Enter their email; they repeat steps 1–2.
  4. Agree in minutes. CAP shows A→B and B→A results with counts. You both pick the top 2–3.
  5. Export. Download a Markdown/CSV Intro Plan (names, links, notes) to use immediately.

What makes it different

Verbs, not vibes. It's built around explicit actions—can intro, want intro—not ambiguous "connections."

Pairwise by design. Private, one-to-one sharing. No network-creep.

Founder-grade speed. Import, intersect, decide—under five minutes when both lists are ready.

Who it's for

Founders with real investor relationships who want to help without becoming a spreadsheet admin.

Pairs of founders who already plan to swap lists and would rather skip the screen-share archaeology.

Try CAP

Use your own tracker with columns like:

name,entityType,firmName,role,url,notes,relationshipStrength,canIntro,wantIntro,tags

Pro tip: mark only the intros you'll truly make. Curate first; intersection later.

Roadmap (near term)

  • Google Sheets connector and light canonicalization ("Sequoia" vs "Sequoia Capital").
  • Context hints (stage/themes) you can optionally include in the export.
  • Notes templates for fast, specific "why this is a fit" blurbs.

The name

"CAP" is the set-theory symbol for intersection (∩). That's the whole product: intersect two curated sets, surface the meaningful overlap, move.
