Investor Briefing · EcoDomeHomes & M45 · Q2 2026
While venture capital chases AI tools obsolete in a quarter, EcoDomeHomes and M45 offer something different: a tangible, defensible platform for a 500-year asset. One airformed concrete shell technology across three brands, EcoDomeHomes (residential), M45 Systems (commercial & defense), and M45 Agri-Tech (agricultural), backed by an institutional research partnership.

For three years, sophisticated capital has concentrated in one place: the AI race, every model obsolete within months. The returns may eventually arrive. The exhaustion of the same thesis at higher and higher prices already has.
EcoDomeHomes and M45 are not a counter-argument to AI. They are a counter-cycle, for investors who hold their AI position and want the other half of a balanced book.
The Other Side of the Ledger
An asset that exists when the power is off. A 500-year service life. An IP filing, not a sentiment. Three independent markets, each measured in hundreds of billions to trillions. Diversification from a book of intangibles priced on adoption curves that may or may not happen.
Residential construction has not had a structural innovation in over a century. Conventional homes are assembled from thousands of weak joints, last 50 to 80 years, and are rebuilt every generation at enormous economic and carbon cost.
EcoDomeHomes answers this with airformed concrete shell construction: a continuous, joint-free envelope built in a fraction of the time at competitive cost. The result is a hurricane-rated, fireproof residence engineered for 500 years that uses 50 to 75% less energy than a conventional home.
Market Scale
The same shell serves residential, agricultural, and commercial / defense: three independent markets, each in the hundreds of billions to trillions globally, each underserved by disaster-resilient, energy-efficient, fast-built alternatives.
The structural core is an airformed pneumatic shell: sprayed with high-strength concrete, reinforced with advanced composite reinforcement, and insulated with continuous closed-cell foam. One integrated build sequence removes the cost drivers and failure points of conventional construction.
Technical details, including the composite reinforcement methodology, optional shielding layers, and proprietary build sequences, are protected under filed IP and available to qualified parties under NDA.
Scope of application
The same construction system scales across three commercial brands:
Residential
Residential, single-family, multi-family, coastal, compound configurations.
Commercial & Defense
Commercial, silos, data centers, hardened structures, healthcare facilities, industrial food & wine infrastructure.
Agricultural
Agricultural, wine cellars & aging, produce cold storage, growing tunnels, livestock shelter, specialty greenhouses.
The platform has secured formal positioning within Portugal's institutional innovation network and built a multi-region supply chain to deliver against an active project pipeline across Europe and the United States.
Engineering & research partnership
An active partnership with CRIA, the entrepreneurship and innovation division of the University of Algarve, provides ongoing research, validation, and engineering review. It delivers academic-grade testing and continuous iteration, anchoring the platform's technical credibility in Portugal's research ecosystem.
Digital Built Accelerator
Memorable Green and EcoDomeHomes were selected for the Digital Built Accelerator, the first construction-sector program from Técnico Venture Lab (Instituto Superior Técnico) and Unicorn Factory Lisboa. Part of the European DIGITALbuilt consortium and backed by the European Commission and Portugal's Recovery and Resilience Plan (PRR), it chose the company's airformed hulls and M45 systems from a competitive international MVP pool, validating the technology for real-world European deployment ahead of Demo Day.
Multi-region supply chain
Manufacturing and material supply are regionally separated, so the company delivers competitive economics in both markets without exposing either to the other's cost structure or logistics risk:
Active · Univ. of Algarve · Engineering & research
Selected · Técnico Venture Lab & Unicorn Factory Lisboa
100% Portuguese sourcing
Established · Domestic for US builds
Under LOI · 3-residence project
Europe & United States
The company's IP position is filed and active, with international extensions calendared. Technical details and full IP documentation are available to qualified parties under NDA.
Filed & Protected
Filed with the Instituto Nacional da Propriedade Industrial (INPI), Portugal, in February 2026. International extensions through the Paris Convention and PCT are calendared and on schedule.

EcoDomeHomes and the M45 brands operate across two anchor markets with very different demand drivers, plus an expanding international footprint by appointment.
Anchor Market
Anchored in Portugal with a fully domestic supply chain, the European market is the company's operational home. Demand drivers include Mediterranean climate resilience, the rising cost of conventional construction across Southern Europe, NZEB regulatory tailwinds, and a growing buyer appetite for long-lived, low-maintenance residences.
Anchor Market
An established domestic supply chain serves US builds, keeping cost competitive against conventional US construction while avoiding the logistics, tariff, and lead-time risk of transatlantic shipping. Demand drivers include FEMA-grade hurricane and wildfire resilience, energy independence, and the same long-lived, low-maintenance economics as Europe.
Expanding Footprint
Builds outside Europe and the United States are accepted by appointment, supported by partner manufacturing as projects warrant.
What We're Building Towards
The platform, the IP, the institutional research backing, and the multi-region supply chain are in place. The work ahead is project execution at scale across the three arms, with the partners and capital to support that growth.
