OESSE

What OESSE does

OESSE is a privately held Italian sole proprietorship (legal name: OESSE di P.I. Omar Scantamburlo) operating as a certified Energy Service Company (E.S.Co.) under UNI-CEI 11352, accredited by Accredia through Apave. Founded in 2013 and headquartered in San Giorgio in Bosco, province of Padova, the firm delivers energy efficiency consulting, HVAC system design and installation, photovoltaic solutions, and ongoing maintenance services. Service delivery is structured across a design/consulting division and an installation/maintenance division, with five-year renewable maintenance contracts, certified F-GAS technicians, and D.M. 37/2008 qualifications (letters A-G) supporting on-site execution.

The company monetizes through four streams: professional services (energy analysis, APE/AQE certifications, thermotechnical design, ENEA and GSE incentive application filing on behalf of clients), recurring maintenance subscriptions (5-year renewable contracts with 40% markup on services and materials during contract), one-time product sales via a WooCommerce online shop (241 SKUs across HVAC equipment from Ferroli and Daikin, plumbing fixtures, and spare parts), and public-administration project work. Go-to-market is sales-led and event-driven, anchored on Italian government incentive programs (Transizione 5.0, Industria 5.0, Conto Termico 3.0, ecobonus) and on Renewable Energy Community (Comunità Energetica Rinnovabile) aggregation in municipalities under 5,000 inhabitants, where an additional 40% tax credit can be stacked on top of base incentives.

Customer segments span Businesses (Imprese, the primary segment), Public Administration (Pubblica Amministrazioni), Condominiums, and Individual Homeowners, with pain points centered on energy cost reduction, regulatory complexity, and access to certified execution. Distribution is single-country (Italy) via direct on-site service delivery and an integrated e-commerce platform; marketing relies on the company website, social media (Facebook, X, Instagram, LinkedIn), newsletter, and Google Forms lead capture. Reported scale is minimal (1-10 employees), with no disclosed revenue, funding rounds, or institutional ownership.
