ST Sociedad de Tasación

What ST Sociedad de Tasación does

ST Sociedad de Tasación, operating as Grupo ST, is an independent Spanish real estate valuation firm headquartered in Madrid, founded in 1982. Its core service is professional property appraisal and valuation, delivered under regulation by Banco de España and held to ISO 9001, ISO 14001, and ISO 27001 certifications. The firm primarily serves financial institutions requiring certified valuations for mortgage lending and risk assessment, and the broader Spanish real estate sector, with a secondary segment of individual property owners undertaking transactions, refinancing, or legal proceedings.

The company operates as a multi-brand platform: Sociedad de Tasación delivers the core regulated valuation product, ST Consultores provides real estate advisory services, and ST Idea is the technology and innovation division. In June 2021 the firm acquired a majority stake in Visualeo, adding blockchain-based asset verification capabilities that generate immutable digital evidence for legal validation, extending the product portfolio beyond traditional valuation into technology-enabled verification services. The unified digital platform (grupo-st.es) consolidates the legacy brands and integrates direct contact channels — phone, email, WhatsApp, and in-person consultation — alongside corporate social channels for awareness.

The revenue model is professional services: quote-based B2B engagements with financial institutions and real estate sector clients for property valuations, supplemented by consulting and asset verification engagements. Distribution is direct, with no disclosed intermediary or platform channel, and operations are confined to Spain. Pricing is not publicly disclosed, consistent with bespoke institutional engagements. The firm holds no parent company, no institutional or private equity backing is documented in the source material, and there is no evidence of public listing or external financing rounds.
