# Planeteer Capital Check Size: Typical Range, Fund Size, and Founder Fit (2026)

> Looking up Planeteer Capital check size? Maiden fund is $54M (June 2025). Early climate planning band ~$500K–$3M with high uncertainty — stage-based, not firm-disclosed.

If you searched for **Planeteer Capital check size**, you are shortlisting emerging climate seed investors and need a working ticket range before outreach.

## Planeteer Capital check size (practical estimate)

Planeteer does **not** disclose a standard check, and we do **not** yet have a `/fund/` JSON with directory lead stages. What we do know from our [June 2, 2025 fund news](/nyc-vc-fund-news-2025-06-02-planeteer-capital-54m-maiden-fund): a **$54M maiden** climatetech fund writing **pre-seed and seed** globally.

For planning in 2026, founders may model **about $500K–$3M** as an **emerging-manager seed** band. Label this clearly: **high uncertainty**, stage-based analogy to other early climate seed funds — **not** firm-disclosed.

Exact size will depend on:

- Fund I ownership and reserve math on a $54M vehicle
- Lead vs. follow
- Climate thesis fit (industrial / grid / risk — not green veneer)
- Whether Planeteer is first institutional capital

### Early climate seed (indicative)

| Situation | Working model | Notes |
|---|---|---|
| Pre-seed / first check | Lower end of ~$500K–$3M | Emerging Fund I — uncertain |
| Seed lead / co-lead | Mid band | Still constrained vs. mega-franchises |
| Later follow | Case-by-case | Maiden-fund reserves vary |
| vs Collaborative climate | Often smaller than Collab $1M–$10M seed/A band | Different franchise scale |

## What we know (news coverage)

- **Firm:** Planeteer Capital (NYC)
- **Fund size:** $54M Fund I (announced June 2, 2025)
- **Focus:** Climatetech pre-seed and seed
- **Themes:** Industrial decarbonization, climate risk, supply chains, grid, resource resilience
- **Team signal:** Sophie Purdom (Partner); Maggie Mullooly (Team)
- **LP signal:** Ivy League endowment anchor; Mike Schroepfer among anchors

## When not to prioritize Planeteer Capital

- No real climate or industrial-decarb wedge
- You need a published check schedule before first contact
- Primary raise is Series B+ growth (wrong vehicle scale)
- You expected Collaborative-scale multi-vintage dry powder on day one of Fund I

## Outreach checklist

1. One sentence on climate outcome (carbon, grid, resilience) with units — not vibes
2. Target raise, runway, and use of funds sized for an emerging seed fund
3. Why Planeteer specifically (maiden climate specialist vs. generalist seed)
4. Warm intro via climatetech operator, mission LP network, or known Planeteer contacts
