Green Impact Exchange Appoints Maria Mähl as Chief Product Officer

NEW YORK, December 3, 2025 — Green Impact Exchange (“GIX”), the nation’s 18th approved stock exchange and the only U.S. exchange dedicated exclusively to sustainable investments, today announced the appointment of Maria Mähl as Chief Product Officer and Executive Vice President. Mähl will lead the execution of GIX’s recently announced product roadmap, positioning the exchange to deliver innovative, institutional-grade financial products as trillions of dollars in global capital are deployed toward the climate transition. As a member of the GIX Executive Team, Mähl will report directly to Daniel Labovitz, CEO of GIX.

Mähl is a sustainability executive and technology business builder who has focused the past 15 years of her career on driving the sustainability transition and scaling growth companies. She has successfully founded and built multiple startups—making GIX her fifth—including taking companies from early capital raises through IPOs. Her expertise spans asset management, sustainable finance, climate transition, regulatory reporting standards, fintech, carbon markets, blockchain, and AI-enabled product development.

Mähl will oversee GIX’s product suite of regulated exchange-traded products for carbon credits, a digital platform integrating blockchain-enabled tokenized assets into traditional market structures, a green economy index licensed to asset managers and ETF issuers, and a listing tier for shares of companies demonstrating material environmental commitments.

Most recently, Mähl served as Partner and Head of ESG Solutions USA at ESG Book, where she helped grow the firm from an initial concept into a global API-enabled SaaS platform delivering sustainability and climate data, analytics, and disclosure solutions to financial institutions and corporates aligned with complex frameworks like CSRD and ISBB. She previously held leadership roles at Arabesque AI Asset Management and the Clinton Global Initiative. Mahl has served on multiple boards and has advised UN bodies, governments, international organizations and venture capital firms, in the finance, climate, and technology space. She has been recognized among Sweden’s Most Powerful Women in Business and Sweden’s 101 Most Powerful in Sustainability.

Maria Mähl, Chief Product Officer and EVP of GIX:

“The sustainable finance ecosystem is entering a defining era, with $30 trillion of capital poised to reshape the global economy. GIX is the only exchange built from the ground up to ensure that this capital is deployed with integrity, transparency, and impact. Having built data and technology platforms that bridge the gap between regulatory standards and commercial viability, I see GIX as having the necessary infrastructure to scale this market. I am thrilled to lead GIX’s product strategy to bring groundbreaking sustainability-focused solutions—from carbon credit instruments to tokenized assets—into mainstream markets.

Together, we will empower investors and companies to drive the growth of the green economy.”

Dan Labovitz, CEO of GIX:

“Maria’s appointment is a significant win for GIX. She brings not only an intricate knowledge of the climate transition and sustainable finance space, but also the entrepreneurial drive of someone who has successfully navigated the journey from seed stage to IPO. Her deep technical background in AI and data standards ensures our products will meet investors’ rigorous demands. With Maria spearheading our product roadmap, GIX is ready to redefine how markets allocate capital toward sustainability.”
