Kyero
Kyero is an international property portal operated by Portal47 Ltd. The website lists residential property for sale and rent from estate agents in Spain, Portugal, France and Italy, with a focus on international buyers. The company was founded in 2003 by Louise and Martin Dell and is based in Bath, England.
History
Kyero was founded in 2003 by Louise and Martin Dell, who had moved from the United Kingdom to Spain. Initially focused on Spain, the portal later added property listings in Portugal, France and Italy, and by 2021 it covered all four countries.
By 2010, the website listed around 100,000 Spanish properties advertised by about 1,500 estate agents. Trade press reported that in 2021 the company adopted a model under which estate agents could list properties without charge while paying for enhanced listings.
Proposed acquisition by Idealista
In December 2024, the Spanish property portal Idealista announced an agreement to acquire Portal47 Ltd, the company that operates Kyero, with completion subject to competition approval in Spain and Portugal.
In June 2025, the Portuguese Competition Authority (Autoridade da Concorrência) opened an in-depth review of the proposed transaction. The transaction remained under regulatory review into September 2025, when Idealista announced that it would not proceed, citing conditions required by Spain's Comisión Nacional de los Mercados y la Competencia (CNMC). The CNMC archived the case (C/1550/25) after Idealista withdrew its notification, and Kyero was not acquired. Media reports described the withdrawal as resulting from competition authority scrutiny in Spain and Portugal.
Business model and operations
Kyero operates as an online property marketplace. Estate agents and property businesses list homes for sale and rent, and prospective buyers search the site by location, property type and price.
As of 2024, the company employed about 33 people and worked with around 7,000 estate agents across its markets. Its figures on Spanish property prices and on international buyer demand have been cited by media as a source of property-market data.
