Lauren Singer (born May 4, 1991) is an American environmental activist, entrepreneur, investor, and blogger based in New York City who serves as a director of CH4 Natural Solutions Corp. (MTNE), a special purpose acquisition company that raised $200 million in its IPO on the NYSE. The SPAC, founded in 2024 and originally targeting up to $250 million, is led by CEO and Director David Leuschen (co-founder and Senior Managing Director of Riverstone), Chairman Bert Glover (founder and Managing Director of Impact Ag), and counts Singer among its sponsor group alongside Leuschen and Impact Ag. The SPAC's board also includes Jeffrey H. Tepper, Nat Zwald, Jean Rogers, and Ben Veres. CH4 Natural Solutions Acquisition targets businesses with significant real-asset footprints that may benefit from accelerated methane mitigation initiatives at scale, likely in the agriculture and traditional energy sectors. Singer's involvement in the SPAC aligns directly with her investment focus on methane and super-pollutant mitigation.
Singer is the co-founder and Managing Partner of Overview Capital, a climate-focused venture fund established in 2023 that invests in businesses addressing the mitigation of methane and other short-lived climate pollutants at the pre-seed and seed stages. Overview is driven by the "overview effect," a term coined by author Frank White describing the profound experience astronauts have when viewing Earth from space, inspiring a desire to protect the planet. Prior to launching Overview Capital, Singer served as Head of Sustainability and Impact at Saie (a role she has held for approximately three years and eight months as of the latest available information) and was a Principal at RSE beginning in October 2025. She is also the founder and former CEO of Package Free, a zero-waste retail company she launched in 2017 as a pop-up shop in Williamsburg, Brooklyn, and the founder and CEO of The Simply Co., an organic laundry detergent company she started in 2014 after leaving her full-time job. Earlier in her career, Singer worked as a Sustainability Manager at the New York City Department of Environmental Protection. She is also a co-founder of Repurpose Global, through which she has helped offset 1.45 million pounds of waste.
Singer graduated from New York University in 2013 with degrees in Environmental Studies and Politics. She first gained public attention in 2012 when she began collecting all the waste she produced in a 16-ounce mason jar, documenting her zero-waste lifestyle on her blog Trash Is for Tossers. Her work has been profiled by The New York Times, The New Yorker, Vogue, New York Magazine, MSNBC, NBC, CNN, Yahoo, Fox Business, BBC, and NPR, among others. She has spoken at the United Nations, UNICEF, the Jeju Forum, MasterCard, Booking.com, and Trivago, and has delivered a TEDx talk. Singer has been named a Business Insider "woman to watch," one of InStyle's "50 badass women changing the world," a Well+Good "2020 changemaker," and was featured on the Forbes 30 Under 30 list for Social Entrepreneurs in 2020. She resides in New York, NY.
This record is keyed to SEC CIK 0002108191 — the identifier this person files under in their own name. Every vehicle above is a filing made under that CIK, so “the same person on two shells” is a fact about an SEC identifier rather than about a name that happens to match.
Roles are the strings the filings used, in the order they were filed. Nothing on this page ranks them, infers seniority, or offers a reason why any two of these names recur — a recurrence is a count, and the filings that produced it are linked beside every row. We also hold 6 institutional-holder rows on these vehicles, under 6 distinct name strings, and none of them is counted across vehicles: that table has no CIK column, and matching holders by name would merge firms that are not the same firm.
