Companies Pulse Fund Closes $63M Fund to Back Next-Generation Climate Companies
Pulse Fund, a venture capital firm focused on early-stage, scalable climate companies, has announced the closing of its inaugural fund with $63 million in capital commitments. The new fund will invest in companies developing solutions across four interconnected areas of the global economy: energy transition, infrastructure, food and agriculture, and mobility.
Founded and led by Tenzin Seldon, Founder and Managing Partner of Pulse Fund, the firm takes a systems-level approach to climate investing. Rather than viewing individual climate sectors in isolation, Pulse looks for connections between markets and technologies that could create new opportunities as the global economy transitions toward lower-carbon systems.
According to the firm, developments in one sector can have significant implications for others. Advances in battery technology, for example, can expand opportunities for electric mobility, while improvements in agricultural productivity can influence infrastructure investment and resource allocation. Pulse aims to identify these cross-sector relationships before they become widely recognized by the broader investment market.
“Closing our first fund is a milestone, but the real story is what it lets us build,” said Tenzin Seldon, Founder and Managing Partner of Pulse Fund. “We are at the beginning of the largest capital reallocation in history, and understanding how the energy transition, infrastructure, food and agriculture and mobility move together will define where that capital lands. We back the founders who see those connections before the market does and build companies at the center of them. This close is a mandate to go find more of them.”
Institutional and Strategic Investor Support
Pulse Fund attracted capital from a range of institutional investors, corporations, multi-family offices and strategic backers. Investors in the fund include Beneficient, C6 Partners, Pivotal Foundation, the Pritzker family, Veronica Chou, Director of Novel Fashion Holdings, David Osborn of DRO Investments and an Asian sovereign wealth fund.
Beneficient, a technology-enabled platform serving institutional and individual investors holding alternative assets, is among Pulse Fund’s early institutional investors.
“We evaluate many emerging managers and anchor very few,” said James Silk, CEO of Beneficient. “Pulse cleared more than a year of diligence, and our conviction only grew as the Fund did. Tenzin brings the technical depth and discipline that our GP Primary Commitment Program was designed to support, and we are proud to be among Pulse’s earliest institutional investors.”
The investor base reflects the firm’s focus on climate technologies with the potential to scale across multiple industries. Pulse intends to use the new capital to identify and support founders developing technologies that address major challenges associated with decarbonization, infrastructure resilience, food production and transportation.
Portfolio Spans Multiple Climate Sectors
Pulse has already deployed capital across a portfolio of climate-focused businesses, including Endera, Floodbase, InventWood, it’s electric, Mast Reforestation, Plantible, Twelve and Unravel Carbon.
The portfolio covers a broad range of technologies and business models. These companies are working on areas including electric transportation, climate resilience, advanced materials, reforestation, sustainable food production, carbon management and clean industrial technologies.
Pulse describes itself as an active investor rather than a passive source of capital. The firm frequently leads financing rounds and takes strategic board positions, allowing it to work directly with founders as their companies develop products, raise additional capital and expand into new markets.
John Walsh, CEO and founder of Endera, said Pulse supported the company at a time when commercial electric vehicles were still viewed by many investors as an emerging niche.
“Pulse backed Endera when most investors still saw commercial electric vehicles as a niche bet,” Walsh said. “Tenzin understood that electrifying fleets is foundational infrastructure for the energy transition, and she has brought clarity, strategic rigor and a genuine spirit of collaboration to every stage of our work together.”
Walsh also credited Seldon with helping the company restructure its capitalization table and attract additional institutional investment.

Unravel Carbon CEO and co-founder Grace Sai similarly highlighted Pulse’s hands-on approach. According to Sai, the firm recognized the international potential of Unravel’s technology from the beginning and continued supporting the company as it evolved its business model toward an agentic, AI-native platform.
“Tenzin understood both the climate imperative and the global potential of our solution,” Sai said, adding that Pulse challenged the company’s assumptions around revenue generation and helped the team evaluate its evolving strategy.
NASA Collaboration Adds Scientific Capabilities
Pulse’s strategy extends beyond venture capital through a collaboration with NASA’s Goddard Space Flight Center.
Under a Space Act Agreement signed in 2024, Pulse connects its portfolio companies with publicly available NASA Earth observation data, modeling capabilities and climate technology. NASA Goddard is the agency’s largest center focused on Earth science, and its technology transfer efforts are designed to help move publicly developed scientific capabilities into the private sector.
The relationship gives Pulse and its portfolio companies access to scientific resources that can support the development and evaluation of climate technologies. The firm is also using climate science and Earth observation information to develop tools for measuring, evaluating and monitoring climate impact across its portfolio.
Pulse is additionally working to convene a consortium involving climate-focused funds, accelerators and operators. The goal is to broaden access to publicly available NASA science and help more companies apply those resources while developing and deploying climate solutions.
A Distinctive Leadership Profile
The $63 million first fund represents a significant milestone for Pulse, particularly given the firm’s structure and leadership. The fund is led by Seldon, who has more than two decades of experience working with and scaling climate technologies.
As Founder and Managing Partner, Seldon leads the firm’s investment activity and serves on the boards of several portfolio companies, including Floodbase, Unravel Carbon, Mast Reforestation, Endera, Twelve and BlocPower.
Before establishing Pulse Fund, Seldon co-founded a net-negative infrastructure company focused on the redevelopment and adaptive reuse of historic buildings. Earlier in her career, she worked with the United Nations Environment Programme in Thailand, where she oversaw regional disaster risk reduction policy.
Seldon has also held advisory and board roles with publicly traded companies and nonprofit organizations. Her affiliations have included Marathon Digital Holdings, Stanford University’s Human-Centered Artificial Intelligence initiative, the UN NGO Creative Visions Foundation and One Earth. She has also lectured at Harvard University, the University of Oxford and Stanford University.
Her background includes recognition as a Harry S. Truman Scholar by the U.S. Congress, an Inc. Female Founder 500 and a World Economic Forum Global Shaper, among other honors. She graduated Phi Beta Kappa and summa cum laude with highest distinction from Stanford University and later earned a dual master’s degree as a Rhodes Scholar at the University of Oxford.
