ProntoPiso

ProntoPiso was a Spanish proptech that guaranteed the sale of a residential property within 90 days, advancing the owner roughly 95% of the home's market value if it failed to sell in that window, effectively turning sellers into cash buyers for their next home. Incubated in 2017 by Antai Venture Builder, it operated in Barcelona and Madrid and raised roughly €8.5-9M in equity, venture debt and media-for-equity. The company is defunct — after years of losses (over €10M accumulated) and a management change in 2021, it filed for bankruptcy (concurso de acreedores) in Barcelona and was insolvent in 2023.
