# Collaborative Fund Check Size: Typical Range, Stage Focus, and Founder Fit (2026)

> Looking up Collaborative Fund check size? Here is a practical stage-based estimate, Collab SOS context, and how founders should qualify outreach.

If you searched for **Collaborative Fund check size**, you are shortlisting climate and consumer investors and need a working ticket range before outreach.

## Collaborative Fund check size (practical estimate)

Collaborative Fund does **not** disclose a standard check. For planning in 2026, founders commonly model **about $1M–$10M** when Collab leads **seed or Series A** — the same stage-based band we use for other seed/Series A lead firms in the [directory](/directory).

Treat that as a **working estimate**, not a guaranteed quote. Exact size depends on:

- Round type and total size
- Lead vs. follow
- Climate / consumer-health thesis fit
- Which vehicle is writing (core funds vs. [Collab SOS $200M climate](/2026-collaborative-fund-collab-sos-200m-fund))

### Seed vs Series A (indicative)

| Situation | Working model | Notes |
|---|---|---|
| Institutional seed lead | Lower end of $1M–$10M | Strongest when mission + early commercial signal align |
| Series A lead / co-lead | Mid-to-upper end of band | Collab SOS can matter for climate-heavy rounds |
| Follow on later round | Often smaller than a lead | Concentration and reserves vary |

## Stage focus (directory data)

- **Rounds they lead:** Seed, Series A
- **Rounds they invest:** Pre-Seed → Series B+
- **HQ:** 675 Avenue of the Americas, New York, NY
- **Sectors we tag:** climate-tech, consumer

Best fit when you can show measurable climate or consumer-health leverage — not a generic software pitch with a green veneer.

## When not to prioritize Collaborative Fund

- Pure enterprise infra with no climate/consumer-health wedge
- Ask far above the working band with no path to Collab as a meaningful owner
- You need a disclosed published ticket size before first contact (they do not publish one)

## Outreach checklist

1. One sentence on mission outcomes (carbon, health, food system) — not vibes
2. Target raise, runway, and use of funds
3. Why Collab specifically (portfolio adjacency: WHOOP, climate peers)
4. Warm intro path via portfolio or co-investor
