xemx is a biotech energy company turning ordinary painted surfaces into distributed clean energy sources — with no structural changes, no new infrastructure.
The Challenge
Renewables are growing — but every existing solution demands structural change. Rooftop solar needs south-facing roofs. Wind is incompatible with cities. The result: billions of square metres of vertical wall surface sit entirely passive, generating nothing.
Easy to adopt and genuinely energy-generating — the space in the middle has remained empty.
30–40%
of global energy-related CO₂ comes from the built environment
70%
of urban building surface area is vertical façade — generating zero energy

existing walls. No new land, permits, or structural change needed.
The Opportunity
The built environment has been treated as passive infrastructure — a cost centre. xemx inverts that logic. Every painted wall becomes a revenue-generating, carbon-removing, data-producing surface.
For Developers
Integrating xemx unlocks energy-generating real estate — a differentiated asset in a market driven by sustainability credentials.
For Residents
Every deployed surface generates electricity for on-site use or grid export. Carbon credits are automatically tracked and deposited quarterly.
For the Grid
xemx turns vertical façades into micro-generation nodes — decentralising energy production and reducing dependence on large-scale infrastructure.
Three Core Capabilities
A bio-engineered coating that captures sunlight and converts it into low-voltage electricity through a natural photosynthetic process — applied exactly like conventional paint.
As the coating works, it draws CO₂ from the surrounding air as part of its biological process, releasing oxygen — turning every wall into an active environmental asset.
Embedded IoT sensors — powered by the paint itself — provide continuous monitoring of energy output and air quality, enabling automated carbon credit trading and real-time ESG data.
Universal Adoption Path
Billions of litres of paint are applied to buildings every year, across every geography, every building type, every climate. xemx doesn't ask for new behaviour — it upgrades the material people are already buying.
The adoption pathway is the same as any trade coating. The return profile is categorically different.
The Product
Apply it. Connect it. Generate clean energy and earn carbon credits — automatically, with no structural change to the building.

Who We Work With
xemx is offered exclusively to real estate developers and construction groups already committed to sustainability — not as compliance, but as a genuine business imperative.
xemx performs exactly like any professional-grade paint, but what sets it apart is its ability to generate electricity from sunlight and absorb CO₂ from the ambient air — turning every coated surface into a quiet, continuous contributor to energy output and carbon reduction.
Mid- to large-scale residential builders seeking differentiated assets that command premium positioning in a sustainability-driven market.
Office and mixed-use developers seeking verifiable ESG credentials, reduced operational energy costs, and carbon credit revenue across portfolio assets.
Specialist build contractors who can introduce xemx as an integrated offering across multiple client projects.
Developers in markets where energy regulations create direct commercial benefit for integrating distributed renewable generation.

Origin & Vision
With xemx, paint becomes more than a coating — it becomes a global platform for clean energy, air purification, and environmental intelligence.
xemx is the Maltese word for sun — symbolising light, warmth, and new beginnings. Historically used in literature and poetry to depict hope, energy, and infinite power. The name is not incidental. It is a commitment.
We believe energy shouldn't require new infrastructure. It could be built into what already exists. At xemx, we're turning every surface into a power source — starting from the lab, scaling to the factory, and ultimately to every building on earth.

For Real Estate Companies
We work with a select group of residential and commercial developers to bring xemx into new projects. If you're planning a development and want to understand how energy-generating surfaces could work for you, we'd like to hear from you.
Residential developers
xemx integrates into new residential builds without changing how you design, specify, or construct. Applied at the finishing stage alongside conventional coatings, it turns exterior façades into income-generating, carbon-reducing assets for your buyers.
Commercial & mixed-use
For commercial portfolios where sustainability reporting is both a regulatory requirement and a competitive advantage, xemx provides verifiable, real-time carbon and energy data embedded in the building itself — not bolted on after the fact.
Investors
xemx is a pre-commercial biotech energy company at the intersection of biotechnology, clean energy, and real estate. We are in active dialogue with institutional and strategic investors.
