Key takeaways

  • The Lemelson Foundation is a strong fit for organisations working in invention education, invention and entrepreneurship, or climate action, particularly where work reaches children from low-income communities or groups under-represented in STEM, or supports inclusive regional business ecosystems.
  • Geographically it prioritises the United States, Oregon, India, Kenya and global work.
  • Most grants to organisations fall between $19,500 and $500,000, with a median of about $100,000, so a modest request in that range is realistic, though some grants have gone as high as roughly $3,050,000.
  • Its approach is collaborative and relationship-driven, and grants are primarily awarded through invitation, so the practical route in is to send a brief email introduction setting out a strong fit with its strategic priorities rather than a full unsolicited proposal; it accepts applications on a rolling basis.
  • A large share of its grant dollars goes to organisations it has funded before, so new applicants should expect this to be a relationship-led, competitive process best approached through genuine strategic alignment; it does not provide direct funding to individuals.

Priority Areas

The Lemelson Foundation provides catalytic funding to build vibrant invention ecosystems and works with partners to cultivate impact inventors and support invention-based businesses. Its work spans invention education, invention and entrepreneurship, and climate action. It funds invention education programmes across the United States, with particular attention to children from low-income communities and groups under-represented in STEM, and supports student-led invention projects and invention cultures in higher education. Its entrepreneurship work strengthens inclusive regional ecosystems, local business enablers, access to capital and pathways for businesses to grow, including in the United States, India and Kenya. Through climate action, it supports innovative approaches to decarbonising the global economy, with an emphasis on justice and learning and on inclusive solutions for communities left behind. Its approach is collaborative and relationship-driven, supporting programmes and organisations that advance positive social impact, environmental responsibility and financially self-sustaining businesses.
