Subastech

Subastech is a Spanish technology platform specialized in applied intelligence for real-estate auctions. According to its own description, it was created to transform the fragmented information surrounding each auction into a well-founded decision. The platform centralizes data from multiple sources — including BOE (Boletín Oficial del Estado) judicial auctions, Social Security auctions, Catastro (land registry), the Property Registry and real market data — and converts it into due diligence for bidders: charges (cargas), possession status, auction value, minimum bid, estimated ROI and legal risk. It combines proprietary AI with real-estate technicians who, per the company, bring more than 30 years of sector experience. The problem Subastech addresses is that while digitalization has made Spanish auctions easier to reach, they remain extremely complex to analyze. Investors must consult multiple sources, interpret legal documentation, review charges, validate registry data and cross-reference dozens of factors. Subastech's pitch is that it lets users decide in 60 seconds what most people take hours to analyze, and it cites an average manual evaluation time of 8–10 hours per opportunity. Its tools include scoring systems and a traffic-light (semáforo) style risk indicator, plus a monitoring feature called Radar that watches the market. The service is offered with a free start and no credit card required, and can be cancelled at any time. Subastech positions itself in the Spanish auction market, which it describes as underpenetrated: it reports an average of 1,168 new judicial auctions per month, growth of 42% in 2025 versus 2024, and 53% of auctions going unsold without any bids. The company frames this as an opportunity gap — many properties sell below market value, yet more than half receive no bids because bidders cannot easily understand what they are buying. Subastech's answer is professional due diligence before bidding. The brand operates as a technology platform rather than a traditional brokerage, selling analysis and decision-support tools to investors, professionals and companies. Its website is subastech.com, and it is described in Wikidata as a Spanish technology platform for the analysis of judicial real-estate auctions. Ownership, founding year and headquarters are not specified in the available evidence.

Subastech is a Spanish technology platform specialized in applied intelligence for real-estate auctions. Its own account states that it was born to transform the fragmented information of each auction into a founded decision. The company describes the context of its creation: the real-estate auction market has been deeply transformed in recent years by digitalization and online access to auction processes. Reaching opportunities is now easier, but analyzing them correctly remains extremely complex. Investors must consult multiple information sources, interpret legal documentation, review charges, validate registry data and cross-reference dozens of factors that can determine the success or failure of an operation. The information exists, but it is often fragmented, dispersed and requires specialized knowledge to interpret well. Subastech was created to address that gap. It centralizes information from multiple sources, analyzes it, relates it and transforms it into useful information so that investors, professionals and companies can assess opportunities with more speed, security and judgment. It combines advanced technology, data analysis and proprietary valuation systems with expert knowledge of the real-estate sector, identifying risks, contextualizing information and facilitating decision-making on each opportunity. The company emphasizes that it provides tools rather than raw data, offering scoring systems and traffic-light style indicators. The platform's scope covers BOE judicial auctions, Social Security auctions, Catastro, the Property Registry and real market data, delivering due diligence before bidding: charges, possession status, auction value, minimum bid, ROI and legal risk. It uses proprietary AI alongside real-estate technicians who, according to the company, have more than 30 years of experience. A monitoring feature called Radar watches the market, and the service can be started for free without a credit card and cancelled at any time. Subastech frames its market with figures it attributes to BOE, AEAT and CGPJ sources: an average of 1,168 new judicial auctions per month, growth of 42% in 2025 versus 2024, and 53% of auctions going unsold without bids. It argues that the problem is not finding auctions but understanding what one is really buying before bidding. The available evidence does not specify the founding year, founders, headquarters or ownership structure of the company.
