About us
Overview
i(x) Net Zero (“IXNZ”) is a targeted capital platform founded in 2015 to accelerate the transition to a sustainable, high-performance energy ecosystem. With a disciplined focus on growth equity and real assets in energy innovation, infrastructure, and storage, IXNZ provides shareholders with the opportunity to achieve long-term capital growth and measurable impact.
Our strategy is designed to capture the generational opportunity created by rising global energy demand, electrification, and industrial decarbonization. By backing scalable companies and infrastructure platforms that integrate into the existing energy economy, IXNZ delivers top-tier institutional returns while advancing solutions critical to the energy evolution.
IXNZ aligns shareholder capital with a growing network of strategic partners, family offices, and institutional investors. Through structured investments, active management, and proprietary deal sourcing, we are building a portfolio and pipeline positioned to thrive at the intersection of market demand, energy security, and sustainability.
The Energy Evolution
The global energy economy is not simply transitioning, it is evolving. Electrification, AI-driven data centers, and industrial decarbonization are driving record energy demand, requiring solutions that scale rapidly while integrating with existing infrastructure. Meeting this demand means modernizing the grid, deploying large-scale storage, and investing in technologies that deliver reliable, low-carbon power at scale.
The energy evolution spans every sector of the economy. Aviation and maritime shipping must adopt sustainable fuels. Buildings must be constructed and operated with new green technologies. Waste must be transformed into renewable fuels. And carbon capture must move from concept to commercial scale—turning emissions into valuable resources and fueling a carbon-to-value economy.
At IXNZ, we see this evolution as the defining investment opportunity of our time: where innovation and infrastructure converge to create lasting financial returns and measurable climate impact.
In the US alone, $1.4T+ of energy infrastructure investment will be required by 2030 .
Investment Thesis
The current energy market is defined by a mismatch between surging demand and outdated infrastructure. AI data centers, industrial decarbonization, and electrification are straining grids worldwide, while trillions in capital are required to modernize energy systems. At the same time, generalist capital is retreating from climate funds, leaving many promising assets underfunded or stranded.
IXNZ provides the solution by focusing on the sweet spot between high-growth companies and real energy assets. Our disciplined approach targets cash-flowing or near-commercial businesses with proven demand, proprietary technology, and scalable infrastructure. We structure investments through direct stakes and SPVs, pairing shareholder capital with strategic partners to accelerate growth, secure offtake agreements, and position assets for exit.
This creates a unique opportunity: IXNZ sits at the intersection of innovation and infrastructure, capturing upside from early-stage growth while delivering institutional-grade stability through real assets. It is this balance—growth equity with downside protection—that defines IXNZ’s business model and drives superior returns in the energy evolution.
Our Business Model
IXNZ’s business model is built around a disciplined, three-step investment process designed to maximize returns while de-risking execution. First, we identify and invest in high-growth assets with proven demand, proprietary technologies, and strong market positioning—often at favorable entry valuations. Second, we work closely with management teams and partners to optimize and scale operations, accelerating commercial adoption, securing feedstock and offtake agreements, and enhancing margins. Finally, we execute structured exits through IPOs, acquisitions, or secondary sales, aligning investments with clear liquidity events and value inflection points.
This process allows IXNZ to consistently generate top-tier returns while advancing real-world energy solutions. Our investment focus lies in scalable, cash-flowing or near-cash-flowing businesses where innovation meets infrastructure—opportunities large enough to absorb meaningful capital, yet underserved by generalist funds. By combining growth equity with structured capital and real assets, IXNZ captures both high-growth upside and the stability of inflation-resilient cash flows.
