Planet Heritage Foundation Inc.

Planet Heritage Foundation Inc. is a tightly held family foundation governed by Co-Founders Addison M. Fischer (President) and Cindy Mercer (Vice President), with Olivia Fischer serving as Director and Vice President. All three officers serve without compensation, and the foundation is administered through Foundation Source, a professional back-office service for private foundations at 501 Silverside Rd, Wilmington, DE.

The foundation's core mission is environmental protection and improving planetary health across four priority areas: Clean Energy & Climate, Marine Conservation, Sustainable Development, and Wildlife & Biodiversity Protection. It was incorporated in 2009 and has operated continuously on a family-funded endowment, receiving no external contributions since at least 2019.

The single most important strategic fact for prospective applicants: Planet Heritage does not accept unsolicited proposals or letters of inquiry. This is not a policy footnote — it is their explicit, first-listed statement on the contact page. All grant candidates are identified through (1) intensive internal research by foundation leadership across their priority areas, or (2) referrals from fellow grantmakers and field experts they trust.

This philosophy reflects the founders' backgrounds. Addison Fischer launched his first technology startup in 1973 and became majority owner of RSA Data Security, the firm behind VeriSign — giving him a systems-thinker, entrepreneur-investor orientation toward philanthropy. Cindy Mercer began her career as an intern to President Jimmy Carter and supported the Carter Center's establishment, bringing a governance, global partnership, and human-dignity lens. Olivia Fischer is multilingual across eight languages, suggesting international reach and cross-cultural programming capacity.

The grantee list reveals a strong preference for large-platform intermediaries — Rockefeller Philanthropy Advisors ($4M across 4 grants for the Oceans 5 Alliance) and National Philanthropic Trust ($2.15M across 9 grants) — alongside smaller mission-aligned organizations in ocean conservation, environmental media, AI policy, and biodiversity research. First-time candidates should cultivate relationships with organizations already in this orbit rather than approaching the foundation directly. Being named as a recommended grantee by a current Oceans 5 Alliance partner carries far more weight than any direct application.

Planet Heritage Foundation's 32 recorded grants total $6,927,175, with an average of $216,474 per grant. However, two anchor relationships — $4,000,000 to Rockefeller Philanthropy Advisors (Oceans 5 Alliance, 4 grants) and $2,150,000 to National Philanthropic Trust (charitable outreach/general, 9 grants) — account for 90% of total disbursements. Among the remaining 19 direct grants, the average falls to approximately $40,900, and the range spans from $15,000 (Naples Ballet and Company, Florida) to $275,000 (Redford Center, 'Deep Rising' documentary). The foundation's internal database record cites a median grant of $55,000 and a range of $15,000 to $1,000,000.

Annual giving has followed a pronounced decline over the foundation's history. Total giving peaked at $4.43M in FY2020, driven by outsized Oceans 5 Alliance commitments channeled through Rockefeller Philanthropy Advisors. Giving then fell to $2.97M (FY2021), $2.14M (FY2022), and dropped to approximately $761,043 in FY2024 — a decline of 83% from the 2020 peak. Assets have fallen in parallel from $49.6M in 2011 to $21.6M in 2024, representing a 56% reduction in endowment value over 13 years. The foundation posted negative revenue of -$168,693 in FY2024, indicating the investment portfolio underperformed expenses.

Thematically, ocean and marine conservation accounts for approximately 65% of total historical grant dollars; philanthropic intermediaries (Rockefeller, NPT) represent ~26%; environmental media (Redford Center) ~4%; AI and technology policy (CAIDP) ~2%; and biodiversity/ecological research (Gaia Foundation, University of Vermont Jumping Worm Campaign) ~3%.

Geographically, Pennsylvania leads with 9 grants, followed by New York (4), Vermont (4), California (4), Washington DC (3), and Florida (1). This distribution reflects organizational headquarters of grantees rather than any regional restriction.

The contraction from $3M+ annual giving to under $1M suggests a foundation shifting toward more selective, higher-impact tranches rather than broad distribution — favoring organizations that can demonstrate measurable, scalable environmental outcomes.

The following table compares Planet Heritage Foundation to four asset-equivalent peers in the Philanthropy & Grantmaking NTEE category (T20), all with assets clustered near $21.6 million:

Planet Heritage stands apart from these asset-equivalent peers in three ways. First, it has a sharply defined environmental mission — marine conservation, clean energy, and biodiversity — while most peers in this tier are generalist family or philanthropic intermediary foundations with no stated thematic focus. Second, Planet Heritage has a documented track record of high-profile collaborative funding through vehicles like Oceans 5 Alliance and Aligned Intermediary, indicating a preference for leverage and systems-level impact over direct grants. Third, its invitation-only model is more restrictive than typical foundations in this asset tier; Leverlab Foundation (CO), for example, maintains a public website and may have a more accessible application process for organizations in the Colorado-region nonprofit ecosystem. Applicants who cannot access a Planet Heritage referral pathway should investigate Leverlab and Daofeng & Angela Foundation as alternative comparable funders.

No public news announcements, press releases, grant award disclosures, or leadership changes for Planet Heritage Foundation were identified in web searches covering 2025 and 2026. The foundation has no social media channels, no grants-awarded page on its website, and no public blog or news section. Its communications footprint is minimal by design.

The most recent documented grantmaking activity comes from IRS Form 990 filings. The FY2022 990 shows $2.035M in grants paid. The FY2024 data from ProPublica shows $761,043 in charitable disbursements — the lowest annual giving figure in the available record — with negative total revenue of -$168,693.

Key historical milestones: In FY2020, the foundation made its largest known grants, directing approximately $1.5-2M to Rockefeller Philanthropy Advisors for the Oceans 5 Alliance (total Oceans 5 funding across 2019-2022 reached $4M). In FY2019-2022, CAIDP received three grants totaling $125,000 to support public education on AI policy and democratic values — a notable thematic expansion beyond environmental programming. The Melimoyu Foundation received five grants totaling $122,175 between approximately 2019 and 2022 for a Coastal Marine Protected Area initiative, likely in Chilean Patagonia.

The Redford Center documentary grant of $275,000 for 'Deep Rising' (examining deep-sea mining) is among the most recent notable single-grant entries and illustrates the foundation's interest in using film and public media as conservation tools. Leadership has remained stable since founding — Addison Fischer, Cindy Mercer, and Olivia Fischer have held their respective roles continuously.

Because Planet Heritage Foundation does not accept unsolicited proposals, the entire 'application' strategy is a relationship cultivation effort — not a submission workflow. The following tips are specific to this funder's model.

Path 1 — Be discoverable through internal research. Foundation leadership scans its four priority areas (Clean Energy & Climate, Marine Conservation, Sustainable Development, Wildlife & Biodiversity Protection) through their own research. To surface in this scanning: maintain a current, substantive website with a clear theory of change; publish impact reports, white papers, or peer-reviewed research in your domain; seek coverage in environmental sector press (Yale Environment 360, Inside Climate News, Marine Conservation Society publications); and register your organization in Candid/GuideStar with full programmatic detail.

Path 2 — Referral from a grantmaker or field expert. This is the highest-probability approach. Map your relationships to the Oceans 5 Alliance network: Bloomberg Philanthropies, Oak Foundation, Waitt Foundation, Leonardo DiCaprio Foundation, Rockefeller Philanthropy Advisors, and Melimoyu Foundation have all been in the Planet Heritage grant ecosystem. A credible introduction from any of these organizations is your strongest asset. The Gaia Foundation and RAND Corporation (also past grantees) represent additional connection points.

Language and framing. Addison Fischer's background as a tech entrepreneur means he responds to scalability arguments, systems-level leverage, and entrepreneur narratives. Use language like 'strategic collaboration,' 'scalable innovations,' 'early-stage capital for social and environmental entrepreneurs,' and 'transformative impact' — these mirror the foundation's self-description exactly. Avoid generic nonprofit language about 'programs served' without connecting to systems change.

Timing and capacity. With assets at $21.6M and giving declining to ~$761K in FY2024, this foundation is in spend-down mode. A cultivation effort launched now may yield results in 2026-2027 at most, and grant sizes are likely to be in the $50,000-$150,000 range for direct grantees (excluding large intermediary tranches). Do not build a budget around a Planet Heritage grant as a primary revenue source.

Environmental media. If your work involves documentary film, public education campaigns, or journalism, the Redford Center grant ('Deep Rising') is direct precedent. Frame media work as a strategic policy lever — emphasize intended audience reach among policymakers, industry leaders, or the general public — not as artistic output.
