Building the trust layer for Southern European real estate.
Southern Europe's residential real estate market is valued at over €30 trillion (Statista, 2025). Most of it still trades on paper, broker relationships, and information asymmetry. Northern European markets digitised twenty years ago. Portugal, Spain, Italy, and Greece never did. FAIRBANK exists to close that gap.
We build, own, and operate the infrastructure Southern European real estate has been missing.
Identify
We map structural gaps in Southern European property markets. Verification failures, data blind spots, infrastructure missing from the transaction. We build only when the gap creates durable demand.
Build
Each FAIRBANK product is built in-house, AI-native from day one. We design, develop, and ship the technology ourselves. No white-labelling. No off-the-shelf platforms repurposed.
Operate
We run the companies. FAIRBANK provides shared technology infrastructure, regulatory expertise, and capital to each product as it scales. Each product operates as its own brand, with its own market.
Southern European real estate runs on fragmented, analog infrastructure. That creates the largest unbuilt opportunity in European property technology.
Southern Europe is home to four of the EU's largest residential property markets: Italy, Spain, Portugal, and Greece. Together they represent a residential property base valued at over €30 trillion (Statista, 2025). Yet the infrastructure beneath the market remains decades behind. Pre-purchase verification exists but follows no common standard. Property data sits in disconnected municipal databases. High-value supply moves through trusted networks with no infrastructure beneath it. Buyers, foreign and domestic, transact on incomplete information and absorb liabilities they do not fully understand.
The regulatory environment is accelerating the gap, not closing it. Portugal's Decreto-Lei 10/2024 transferred 100% of undisclosed-defect liability to buyers. The EU's Energy Performance of Buildings Directive (EPBD 2024/1275) mandates renovation passports across the bloc by May 2026. Italy, Spain, and Greece face parallel regulatory transitions on different timelines.
These are not edge cases. They apply to millions of transactions across four countries that share more than they differ. Mediterranean climate stock, fragmented municipal data, foreign-capital-heavy demand, analog professional networks, and weak digital infrastructure. FAIRBANK builds at the intersection of regulatory obligation, capital flow, and verification gap.
Portugal is where we proved the thesis. Southern Europe is where we apply it.
Three products. One verification chain.
Each FAIRBANK product addresses a distinct phase of the property lifecycle: find, verify, own. They share common ownership and infrastructure. They operate as separate brands, with separate management, serving distinct audiences.
InspectOS
inspectos.pt
Certified property inspection infrastructure for Southern Europe.
InspectOS is the verification layer of the FAIRBANK stack. A three-phase inspection framework covers pre-purchase due diligence before the promissory contract (CPCV) is signed, active construction and renovation monitoring, and final handover certification. The framework verifies structural condition, energy compliance, gas and electrical safety, moisture analysis, and permit status. One standard, one reporting format, one auditable digital record.
InspectOS was built around Portugal's DL 10/2024 regulatory regime, which transferred undisclosed-defect liability to buyers at the escritura. Inspections are executed by certified professionals: Ordem dos Engenheiros civil engineers, ADENE-accredited energy specialists, and DGEG-registered gas technicians.
The gap it fills
Inspections existed in Portugal before InspectOS. No unified protocol brought pre-purchase, construction-phase, and final certification under one standard, one reporting format, and one auditable digital record. InspectOS is that standard.
Rezerva
rezerva.pt
Vetted properties. Qualified buyers.
Rezerva is the discovery layer of the FAIRBANK stack. A verified property network where every property is vetted and every buyer is qualified. Designed for buyers and owners who don't operate in public.
Most high-value property in Southern Europe never reaches a public portal. The best deals close before they list. The best buyers don't browse, they get introduced. The best supply moves through trusted networks, not search results. Rezerva is the infrastructure beneath that network. For qualified buyers, including individuals, family offices, and institutional capital, Rezerva surfaces verified properties matched to verified intent. For owners, Rezerva offers access to capital-ready buyers without public marketing or open viewings. Membership is by application.

homeos.pt
Property intelligence and asset management for owners.
HomeOS is the ownership layer of the FAIRBANK stack. A property intelligence platform that turns ownership from paperwork into a managed asset. Three modules: a document vault for ownership records and legal documents, a compliance calendar tracking EPBD deadlines and regulatory obligations, and a renovation history log creating a continuous asset record.
HomeOS is for owners who treat property as a long-term asset rather than a static possession. It is also built for the family offices, advisors, and operators who manage property portfolios on their behalf.

FAIRBANK is operated AI-native from day one. A lean team of operators, engineers, and regulatory specialists builds and runs the portfolio from Cascais, Portugal. Shared technology infrastructure powers all three products. Verification workflows, data pipelines, and regulatory tracking are built once and applied across the stack.
The operating model is a deliberate choice: build the technology ourselves, operate the companies ourselves, and maintain a single quality standard across the portfolio. We do not outsource the infrastructure that defines our products.
Three operating products across find, verify, own
Regulator-aligned with DL 10/2024, EPBD, and DL 97/2017
AI-native operating model. Shared infrastructure across the portfolio.
The rules are changing across Southern Europe. The infrastructure to operate within them is not keeping up.
Three converging regulatory shifts define the next 24 months in European property, and create the demand that FAIRBANK products are built to serve.
DL 10/2024 — Simplex Urbanístico
Effective January 2024. Eliminated mandatory municipal verification at point of sale. Transfers all undisclosed defect liability to the buyer at the escritura (deed of sale). For buyers — foreign and domestic — this means the inspection and due diligence they conduct before signing is now the only protection they have.
EPBD Directive 2024/1275
Portugal's transposition deadline is 29 May 2026. Class G properties are already banned from new rental contracts from January 2026. Renovation passports become mandatory by May 2026. An estimated 35.8% of Portuguese buildings need restoration work (INE Census 2021).
Gas compliance gap
APEG — the body that previously certified gas inspection companies — dissolved on 31 December 2025. An estimated 50–60% of properties requiring mandatory gas inspections under DL 97/2017 are not currently compliant. Pre-2018 installations must have their first inspection completed by 26 August 2028 (DGEG).
FAIRBANK portfolio companies operate at each of these intersections. The regulatory calendar is the product roadmap.
