You buy a washing machine after reading 20 reviews, but you might spend your life savings on an apartment after seeing it for 20 minutes. That's the asymmetry Aleix del Campo, an architect with over a decade of experience, saw in Spain's housing market [Huffington Post, January 2026]. In 2023, he and computer engineer Omar Lamarca founded Hausum to insert a layer of standardized technical diligence into the process. Their tool is not an AI model or a sensor network. It is a software-guided architect, dispatched to a property with a checklist of over 200 points, delivering a report on structural health and repair costs within a day [Hausum, retrieved 2024].
The architect's wedge
Hausum's bet is that the inspection itself is the product, and software is the method to scale it. The company employs licensed architects who use its proprietary mobile app on-site. The app structures the inspection workflow, prompting the inspector to document conditions across categories like foundations, installations, and finishes. As findings are logged, the app calculates estimated repair costs in real time, aiming to turn a subjective walkthrough into a quantified technical report [Hausum, retrieved 2024]. The output is meant to give a buyer concrete use in price negotiation or the confidence to walk away. This positions Hausum not as a generic proptech platform, but as a managed service with a technology backbone.
Traction in a fragmented market
Early traction suggests the wedge is finding a gap. In its first three months after launching in 2023, Hausum completed 81 inspections [Idealista, February 2024]. The company reported generating approximately €300,000 in revenue from private customers during its first full year of operation, with an additional €200,000 anticipated from business clients [La Vanguardia, August 2024]. Its most notable business client is Berkshire Hathaway HomeServices Spain, which commissioned Hausum to inspect properties it markets [La Vanguardia, August 2024]. This partnership indicates some early validation from within the traditional real estate brokerage ecosystem.
The company's funding history shows a gradual capital build to support this asset-light, service-heavy model.
Targeted 2024 | 0.2 | M EUR
Closed 2026 | 0.5 | M EUR
In February 2024, the company was targeting a €200,000 round for marketing [Idealista, February 2024]. That was followed in October 2026 by a €500,000 seed round led by Diroca, the investment vehicle of Dídac Lee, Roque Velasco, and Carlos Trenchs, with participation from Spicy4Tuna and others [La Vanguardia, October 2026]. After this round, the founders were expected to retain about 70% of the company, with Diroca and Spicy4Tuna each holding roughly 10% [La Vanguardia, October 2026].
The technical breakdown
Scaling a service built on expert labor presents a clear set of technical and operational constraints. The 24-hour report turnaround is a key customer promise, but it creates a hard dependency on inspector bandwidth and geographic coverage. Hausum claims nationwide service across Spain's 52 provinces, which requires either a distributed network of contractors or significant travel logistics [Hausum, retrieved 2024]. The quality and consistency of the report,the core product,are directly tied to the training and calibration of each human inspector using the app. The software can guide and calculate, but it cannot yet see a hairline crack or feel a soft floorboard.
The primary risk at scale is the operational burden of maintaining quality while growing inspector capacity. Recruiting, training, and managing a reliable fleet of qualified architects is a people-intensive challenge distinct from scaling pure software. Economic pressure to inspect more properties per day could conflict with the thoroughness promised by the 200-point checklist. Furthermore, the business model relies on a transaction,a home purchase,that is inherently infrequent for any individual customer, necessitating continuous customer acquisition.
The path to 2027
With €500,000 in new capital, Hausum's immediate focus is likely on talent and territory. The funds are intended for growth, which in this context means adding more inspectors and potentially deepening penetration in key Spanish cities [La Vanguardia, October 2026]. The partnership with Berkshire Hathaway HomeServices provides a template for white-label or enterprise sales channels that could drive more predictable volume. The next twelve months will test whether the company can systematize its inspection process enough to grow beyond the founders' direct oversight without diluting the expert credibility that is its main selling point. For now, Hausum has proven there is demand for its report. The harder proof will be building the machine that can deliver ten thousand of them.
