In New York, the architecture of climate capital markets is still under construction.
Green Impact Exchange (GIX), one of only ten licensed stock exchange operators in the United States, has appointed Alexis Levenson as Chief Communications Officer and Executive Vice President, a newly created role as the exchange builds infrastructure aimed at channeling capital toward the green transition economy.
The hire reflects institutional maturation.
Infrastructure before liquidity
GIX is positioning itself at the intersection of traditional equity markets and climate-focused capital allocation. Its model includes standard listing and trading functions alongside newer financial structures such as equitized carbon credits and tokenized securities tied to real-world assets.
The ambition is structural.
By combining conventional exchange “rails” with products designed to capture environmental value, Green Impact Exchange (GIX) is attempting to build regulated pathways for companies operating in energy transition, resilience, advanced manufacturing, and enabling technologies.
Market design precedes scale.
The appointment follows the recent addition of Chief Product Officer Maria Mahl, who is leading GIX’s roadmap for regulated carbon credit instruments, tokenized securities, and green-economy listing tiers. Together, the hires suggest the exchange is layering product design and institutional positioning in parallel as it seeks to establish credibility within the regulated U.S. exchange landscape.

Communications as market signal
Alexis Levenson joins from Visa, where she served as global head of enterprise communications, and previously held senior roles at Elevance Health, Pfizer, and Guy Carpenter. At GIX, she will oversee corporate affairs and human resources while serving on the Executive Leadership Team.
The mandate is broader than messaging.
As exchanges compete to define credible green market infrastructure, narrative clarity becomes part of institutional positioning. Companies seeking public listings tied to transition technologies face scrutiny from investors balancing growth expectations with regulatory risk, supply-chain resilience, and physical climate exposure.
Credibility must be engineered.
Alexis Levenson said GIX is building a capital markets platform rooted in traditional equity listing and trading, while developing innovative products such as equitized carbon credits and tokenized securities that connect investors to climate-driven opportunities.
A regulated pathway
GIX’s leadership frames the green economy as spanning major sectors, from energy and mobility to infrastructure, advanced manufacturing, software, data, and AI. These companies, it argues, require access to transparent and regulated capital markets as trillions of dollars flow into transition-aligned investments.
The scale is implied.
President Charlie Dolan described Levenson’s experience as critical as the exchange scales, noting the need to navigate shifting market expectations and public-company scrutiny.
Exchanges are evolving.
While green-linked financial instruments continue to mature, the durability of climate capital markets will depend on regulatory legitimacy and investor confidence. GIX is attempting to position itself as a regulated mechanism for capital formation in this space rather than a niche sustainability venue.
Whether liquidity and listings follow will determine if climate-focused exchanges become core market infrastructure or remain specialized platforms within a broader financial ecosystem.
