The short answer: investor mapping is building a short, ranked list of the specific people most likely to invest in your round now, with evidence for each and a real path to reach them. Start from recent behaviour (who wrote a first check at your stage and in your sector in the last 12 months), add fund timing and check size, identify the partner, find the warm path, then tier the list and sequence outreach so the investors you want most see your most practised pitch. A good map is usually 30 to 60 names, and every name has a reason to be there.
Most founder lists are built backwards: famous funds first, then a search for a way in. The result is a long list where most names were never going to invest at this stage. Mapping reverses it: evidence first, then fit, then path.
Step 1: Define your round in one line
Write the round the way an investor would file it: stage, sector, geography, round size, and what the money proves. For example: "pre-seed, B2B AI for logistics, Israeli team selling to the US, $1.5M on a SAFE, to reach five paying design partners." Every filter below is applied against this line.
Step 2: Collect the fields that matter
| Field | Why it matters |
|---|---|
| Last first check at your stage, with date | The strongest predictor. A fund that has not led a pre-seed round in a year is unlikely to start with you. |
| Sector deals in the last 12 to 24 months | Portfolios are evidence; thesis pages are aspirations. |
| Lead or follow | Many angels join rounds that already have a lead; in Fusion's 2025 survey, as reported by VC Cafe, 64% of angels only joined existing rounds. You need to know who can lead. |
| Typical check and ownership target | A fund whose typical check is several times your round will follow at best. |
| Fund vintage and deployment | Late in a fund's life usually means mostly follow-on investments. Our guide on how LPs think explains why. |
| The partner | You raise from a person. Which partner covers your space, and what did they do last? |
| Conflicts | A portfolio company that competes with you can rule a fund out. |
| Warm path | Who can introduce you with real trust, and how strong that connection is. |
Step 3: Score fit
Give each investor a simple score so the list ranks itself. A workable version:
- Stage fit (0 to 3): 3 if they led or co-led at your stage in the last 12 months.
- Sector fit (0 to 3): 3 if they have recent deals in your space without a direct competitor.
- Capacity (0 to 2): 2 if their check size matches your round and the fund is actively deploying.
- Path (0 to 2): 2 for a strong warm introduction, 1 for a weak one, 0 for cold.
Anything below 5 rarely belongs in the first wave. A high score with a cold path is a reason to look harder for an introduction before reaching out.
Step 4: Find the warm path
- Start with people who already invested in you.A committed investor introducing you to the next is the strongest introduction there is.
- Founders in their portfolio.Especially founders a partner backed recently and respects.
- Operators and angels you have worked with,your lawyer, and your accelerator.
- Ask for a forwardable email.Write three lines the connector can forward, so the introduction is easy to make and clear to read.
Some funds read cold email well, and a sharp cold note to the right partner beats a weak introduction. Know which is which for each name. Our guide to warm investor paths goes deeper.
Step 5: Tier and sequence
- Tier 1: the leads you want most.They meet the version of your pitch that has already been tested.
- Tier 2: strong fits.Start here. They are real prospects, and they sharpen the pitch.
- Tier 3: followers and angels.Line them up to join once a lead commits.
- Compress the window.Run first meetings in parallel over two to three weeks so momentum builds and decisions land close together.
Step 6: Keep the map alive
Track every conversation: date, partner, next step, and the objection if there was one. Three repeats of the same objection is a company question to answer before the next meeting. Update the map as the market moves: funds close, partners change, and new angel clubs appear, such as those in the Israel Innovation Authority's angel clubs program.
Where the data comes from
Public sources take you part of the way: fund websites and portfolio pages, round announcements in the press, LinkedIn, and annual surveys such as Fusion's pre-seed report. The hard part is keeping it current and connected: which partner led which round, which funds are still deploying, and who in your network knows them. That is why we built the Velo platform: a continuously updated map of more than 500 funds and 1,400 companies, with the relationships between them, which sits behind our advisory work.
