Executive Summary
PUBLIC Hausum sells a simple proposition into a high-stakes consumer moment: before a home purchase closes, it sends an architect-led inspector to assess the property, document defects, and estimate repair costs, a service that has drawn investor attention after the company reported early revenue and closed a €500,000 seed round in October 2026 [Idealista, February 2024] [La Vanguardia, August 2024] [La Vanguardia, October 2026]. Founded in Barcelona in 2023 by architect Aleix del Campo and computer engineer Omar Lamarca, the company appears to pair domain expertise in residential construction with a software layer that standardizes inspections through an in-house app [Idealista, February 2024] [La Vanguardia, August 2024] [Hausum, retrieved 2024].
The product, according to the company and supporting coverage, reviews more than 200 critical points in a home and returns a technical report within 24 hours, with the app guiding architects through the workflow and calculating estimated repair costs [Hausum, retrieved 2024] [Rankia] [Idealista, February 2024]. That positioning matters because Hausum is not selling general listing discovery or mortgage enablement, it is selling pre-transaction risk reduction at the point where buyers have limited time and limited technical visibility into the asset they are about to purchase [Idealista, February 2024] [La Vanguardia, August 2024].
The early operating signals are promising but still thin by venture standards. Idealista reported 81 inspections in the company’s first three months after launch, while La Vanguardia reported €300,000 of revenue from the private-customer channel in its first full year and said the business channel could contribute up to €200,000 over the same period [Idealista, February 2024] [La Vanguardia, August 2024].
On team quality, the public record is coherent if still founder-centric. Del Campo is described as an architect with more than a decade of experience, while Lamarca is identified as the technology-oriented co-founder responsible for the inspection platform, a combination that fits the product’s blend of field operations and software tooling [Idealista, February 2024] [La Vanguardia, August 2024] [LinkedIn].
The business model is primarily B2C, selling inspections to homebuyers, but the company has also shown some channel potential through work with Berkshire Hathaway HomeServices Spain, which reported a collaboration with Hausum in late 2024 [La Vanguardia, August 2024] [Berkshire Hathaway HomeServices Spain, December 2024]. Capital formation remains modest: coverage points to an earlier 2024 seed process and then a €500,000 round in 2026 backed by Diroca and Spicy4Tuna, with founders expected to retain roughly 70% ownership after the transaction [Idealista, February 2024] [La Vanguardia, October 2026] [Expansión, October 2026].
Over the next 12 to 18 months, the core question is whether Hausum can turn a useful inspection product into a repeatable acquisition and distribution engine without diluting its independence or service quality. The watchpoints are straightforward: expansion beyond founder-led execution, evidence that agency and brokerage partnerships convert into durable volume, and proof that the 24-hour, architect-led operating model can scale nationally across Spain’s 52 provinces without margin compression [Hausum, retrieved 2024] [Berkshire Hathaway HomeServices Spain, December 2024] [La Vanguardia, October 2026].

How the Company Got Here
PUBLIC
Hausum presents a fairly clear early-stage company profile from the public record: it is a Barcelona-based home-inspection startup focused on pre-purchase residential checks, with the service framed around architect-led technical reviews before a buyer closes on a property [Hausum, retrieved 2024]. The company says its inspections review more than 200 points and are delivered through a workflow supported by its own app, which is used to document issues and estimate repair costs [Hausum, retrieved 2024].
On chronology, the confirmed public baseline is still narrow. Public reporting identifies Hausum as founded in 2023 by architect Aleix del Campo and computer engineer Omar Lamarca, while the company website establishes the operating proposition rather than the incorporation trail: inspect the home before purchase and surface technical defects that could alter the buying decision [Hausum, retrieved 2024]. No state filing or company registry detail was provided in the cited materials for this section, so the legal entity name cannot be confirmed here.
The earliest visible milestone from company-controlled sources is product positioning rather than financing: a national inspection offer in Spain, a standardized report built around 200-plus checkpoints, and a stated 24-hour turnaround for the technical report [Hausum, retrieved 2024]. That framing matters because it suggests Hausum was built first as an operational service layer with software embedded into delivery, rather than as a pure listing or transaction marketplace [Hausum, retrieved 2024].

Product and Technology
Product Surface
MIXED Hausum’s product is easiest to understand as a pre-purchase home inspection service wrapped in software. Public materials describe an architect-led inspection of residential properties, with findings captured through an in-house app that guides the workflow, records defects, and estimates repair costs; the output is a technical report that the company says is delivered within 24 hours [Hausum, retrieved 2024] [La Vanguardia, August 2024]. The company website says the inspection covers more than 200 critical points, and third-party coverage in Rankia described the reviews as detailed and exhaustive across the same 200-plus point scope [Hausum, retrieved 2024].
The product scope extends beyond defect identification alone. Hausum also says it offers legal advice tied to home buying and selling, including contract review and risk prevention, and that it can serve customers across all 52 provinces in Spain [Hausum, retrieved 2024]. On the commercial side, coverage from La Vanguardia and Berkshire Hathaway HomeServices Spain indicates that the same inspection layer is being used not only for individual buyers but also in collaboration with real estate businesses, which suggests the core service can travel across both consumer and channel relationships without a visible change in the underlying workflow [La Vanguardia, August 2024] [Berkshire Hathaway HomeServices Spain, December 2024].
Technology Characterization
MIXED The technology claim here is narrower than a full-stack proptech platform, and that distinction matters. Based on public reporting, the software appears to function primarily as an operating system for inspectors: it standardizes the inspection process, structures data capture on site, and calculates estimated repair costs in real time rather than acting as a consumer self-serve product or a marketplace layer [Hausum, retrieved 2024] [La Vanguardia, August 2024]. No verified public demo, engineering documentation, or job-posting trail in the provided sources supports stronger claims about proprietary data infrastructure, automation depth, AI usage, remote diagnostics, or integrations with brokers, insurers, or mortgage workflows.
That leaves the company with a fairly clear product thesis. If the inspection app materially improves consistency, turnaround time, and cost estimation across a distributed architect network, the software could create operating use inside what is otherwise a people-heavy service model; if not, the business remains closer to a standardized expert-services firm than a software-led product company [Idealista, February 2024] [Hausum, retrieved 2024]. Public evidence today supports the existence of the workflow software and the report-based service, but not a broader claim of technical defensibility beyond execution quality and process standardization.

Where the Demand Sits
PUBLIC
The market matters because Hausum sits at the point where a high-stakes consumer purchase meets a still-fragmented diligence process, and the public evidence suggests buyers are becoming more willing to pay for independent technical verification before closing a home transaction [Idealista, February 2024] [La Vanguardia, August 2024].
Hausum does not disclose a third-party TAM, SAM, or SOM, and the source set does not include a named market study for Spanish pre-purchase home inspection software or services. The safer read is therefore from observed demand rather than market-size arithmetic. Idealista reported that Hausum completed 81 inspections in its first three months after launch in 2023, which indicates some early willingness to pay for the service in a category that is not yet a standard line item in every Spanish residential transaction [Idealista, February 2024]. La Vanguardia later reported €300,000 in revenue from the private-customer channel in the company’s first full year, with up to €200,000 anticipated from the business channel, which points to two identifiable demand pools: retail buyers purchasing peace of mind, and real-estate intermediaries looking to reduce transaction friction or post-sale surprises [La Vanguardia, August 2024].
The immediate tailwind is behavioral rather than purely technical. Hausum’s pitch, as described by Idealista and La Vanguardia, is built around the idea that many buyers make large financial commitments after limited on-site inspection time and without a standardized technical report prepared on their behalf [Idealista, February 2024] [La Vanguardia, August 2024]. That creates room for a service that turns a vague concern about hidden defects into a structured checklist, a repair-cost estimate, and a rapid report. Berkshire Hathaway HomeServices Spain’s reported collaboration with Hausum adds a second demand signal, because it suggests at least some brokerages see value in formalizing property-condition review inside the transaction flow rather than treating it as an afterthought [La Vanguardia, August 2024] [Berkshire Hathaway HomeServices Spain, December 2024].
The adjacent markets are clearer than the core market size. Hausum touches residential brokerage services, property due diligence, technical architecture services, renovation budgeting, and legal review tied to home buying and selling [Hausum, retrieved 2024] [La Vanguardia, August 2024]. Those substitutes matter because the company is not only competing for a dedicated inspection budget, if one exists, but also for spend that might otherwise go to a trusted architect, a contractor opinion, a post-purchase renovation contingency, or a buyer’s own informal assessment. That cuts both ways. It expands the possible wallet share per transaction, but it also means the category may require buyer education and channel partnerships before it becomes habitual.
The macro and regulatory backdrop is supportive in principle, though the public materials here stay descriptive rather than legalistic. Spain’s residential market remains costly enough that hidden defects can materially change a buyer’s economics, and Hausum’s service is framed as a way to reduce that information gap before purchase rather than litigate it afterward [Huffington Post, January 2026] [Idealista, February 2024]. The company also offers legal advice and contract review on its website, which suggests management sees home buying risk as broader than physical defects alone [Hausum, retrieved 2024]. Even so, there is no cited public evidence in this source set that inspections of this kind are mandated, subsidized, or standardized across Spain, so adoption still appears to depend more on consumer awareness and partner distribution than on regulation [Hausum, retrieved 2024] [Idealista, February 2024].
| Cited sizing or demand claim | Figure | Market relevance |
|---|---|---|
| Hausum inspections completed in first three months after launch | 81 | Early observed demand for pre-purchase inspections [Idealista, February 2024] |
| Reported revenue from private-customer channel in first full year | €300,000 | Indicates consumer willingness to pay [La Vanguardia, August 2024] |
| Anticipated revenue from business channel in first full year | up to €200,000 | Suggests brokerage and partner demand alongside B2C [La Vanguardia, August 2024] |
| Geographic coverage claimed on company site | 52 provinces in Spain | Expands potential serviceable footprint, though company-only [Hausum, retrieved 2024] |
The numbers here are company-level rather than market-level, but they still frame the opportunity cleanly. Public evidence supports a real buyer pain point and some early commercial validation, while the absence of an independent category size report is a reminder that this may still be an emerging behavior rather than a fully formed market.

Competitive Landscape
MIXED Hausum is not competing against a single well-defined software peer set so much as against a bundle of incumbents and workarounds: buyer intuition, generalist architects, real estate agents, and agency-affiliated service providers that sit closer to the transaction flow [Idealista, February 2024] [La Vanguardia, August 2024] [Hausum, retrieved 2024].
The competitive map is easiest to read in three layers. First are traditional substitutes, meaning independent architects or surveyors hired ad hoc by a buyer to review a property before closing. Those providers likely exist in every local market, but the public record here names no specific firm, so the evidence supports only the category, not market-share claims [Idealista, February 2024] [Hausum, retrieved 2024]. Second are transaction-adjacent actors, especially real estate agencies and brokerages, which often shape what diligence a buyer does or does not perform; Hausum initially explored the agency channel before concluding the end buyer had the clearest need for the service, according to La Vanguardia's 2026 reporting [La Vanguardia, October 2026]. Third are branded distribution partners such as Berkshire Hathaway HomeServices Spain, which has publicly described a collaboration with Hausum and therefore acts as both customer and channel, at least in some transactions [La Vanguardia, August 2024] [Berkshire Hathaway HomeServices Spain, December 2024].
Hausum's edge today appears to rest less on software alone than on productizing an expert service. Public sources describe a workflow in which architects inspect more than 200 points, use an in-house app to standardize the visit, and return a report within 24 hours, with estimated repair costs included [Hausum, retrieved 2024] [Rankia, retrieved 2026]. That combination matters because a buyer choosing between a generic architect and Hausum is not only comparing technical skill, but also consistency, speed, and ease of purchase. The durability of that edge is still open to question. Standardized inspection software and report templates are perishable advantages if other inspection firms or broker networks copy the operating model, while any trust benefit from architect-led inspections could prove more durable if Hausum becomes a recognized consumer brand in Spain [Idealista, February 2024] [La Vanguardia, August 2024].
The company is most exposed where it does not control the transaction. Real estate agencies and portals still own much of the buyer traffic, and larger brokerages can decide whether to partner, build in-house processes, or keep diligence informal. Berkshire Hathaway HomeServices Spain is the only named commercial relationship in the public source set, which cuts two ways: it validates enterprise relevance, but it also shows how much channel influence can sit outside Hausum's direct control [La Vanguardia, August 2024] [Berkshire Hathaway HomeServices Spain, December 2024]. A second exposure is category breadth. The current public positioning is tightly tied to pre-purchase residential inspections in Spain, and the sources do not establish adjacent products such as mortgage, insurance, property management, or post-closing renovation workflows that could widen the moat [Hausum, retrieved 2024] [La Vanguardia, August 2024].
The most plausible 18-month scenario is a channel contest rather than a feature contest. If Berkshire Hathaway HomeServices Spain deepens its use of third-party inspections and similar broker networks follow, Berkshire Hathaway HomeServices Spain is the clearest winner if broker-led distribution becomes the dominant route to buyer adoption, because it would reinforce the brokerage's value proposition while giving Hausum qualified demand at lower acquisition cost [Berkshire Hathaway HomeServices Spain, December 2024] [La Vanguardia, August 2024]. The clearest loser if buyers continue to rely on informal advice and last-minute architect outreach is the fragmented independent-inspector category, because standardized reporting and faster turnaround could pull work away from one-off local providers, although that remains an inference rather than an observed shift [Idealista, February 2024] [Hausum, retrieved 2024]. The reverse also holds: if agencies keep inspections optional and buyer education remains weak, Hausum's model could face slower scaling because the service still has to be explained and sold property by property [Idealista, February 2024] [La Vanguardia, October 2026].
Opportunity
PUBLIC
The prize here is not a nicer inspection report, but the chance to become the operating layer that sits between homebuyers, brokers, and technical due diligence on residential transactions in Spain, and potentially beyond, if Hausum can turn a narrow pre-purchase service into repeatable transaction infrastructure [Idealista, February 2024] [La Vanguardia, August 2024] [Hausum, retrieved 2024].
The clearest upside case is that Hausum becomes the default third-party inspection standard for Spanish home purchases, first in the buyer-led channel and then inside broker workflows. That outcome is reachable, rather than merely rhetorical, because the company appears to have found an understandable pain point early: buyers commit large sums after limited technical review, and Hausum's product is built around a standardized inspection of more than 200 points, a repair-cost estimate, and a 24-hour report turnaround [Idealista, February 2024] [Hausum, retrieved 2024] [Rankia]. The public evidence also suggests early commercial proof. Idealista reported 81 inspections in Hausum's first three months after launch, while La Vanguardia later reported €300,000 in private-channel revenue in its first full year and anticipated up to €200,000 from the business channel, which indicates the product could sell both as a consumer purchase and as a B2B service layered into transactions [Idealista, February 2024] [La Vanguardia, August 2024].
A useful way to think about the upside is through a small number of concrete scaling paths, each with a different trigger. The table below keeps the scenarios grounded in what is publicly evidenced today.
| Scenario | What happens | Catalyst | Why it's plausible |
|---|---|---|---|
| Buyer-side category standard | Hausum becomes the default independent inspection service for urban homebuyers in Spain before signing or closing | Continued buyer adoption driven by fast turnaround and standardized reporting | The company is already positioned around buyer protection, completed 81 inspections in its first three months, and markets a 24-hour technical report covering more than 200 inspection points [Idealista, February 2024] [Hausum, retrieved 2024] |
| Embedded brokerage workflow | Hausum becomes a white-label or preferred inspection layer inside estate-agency and brokerage processes | Partnerships similar to the reported Berkshire Hathaway HomeServices Spain relationship | La Vanguardia reported work with Berkshire Hathaway HomeServices Spain, and the brokerage itself later highlighted the collaboration, suggesting the service can fit institutional real-estate distribution rather than only one-off consumer demand [La Vanguardia, August 2024] [Berkshire Hathaway HomeServices Spain, December 2024] |
| Inspection software plus field network | Hausum evolves from a branded service into software-enabled inspection infrastructure used by a distributed architect network across Spain | Scaling the in-house app and hiring with fresh capital from the 2026 round | Hausum says its app standardizes inspection work and estimates repairs, and the October 2026 financing was reported as growth capital for talent, technology, and internal processes [Hausum, retrieved 2024] [La Vanguardia, October 2026] [Expansión, October 2026] |
If this compounds, it likely does so through standardization rather than through a classic consumer network effect. Each completed inspection can make the workflow more repeatable: the app guides the architect, captures defects in a structured way, and produces repair estimates, which should improve consistency across inspectors and geographies if the process is managed well [Hausum, retrieved 2024]. National coverage is still company-claimed, but Hausum does state that it operates across all 52 provinces of Spain, and LinkedIn profiles tied to the company suggest activity beyond a single local team, which is directionally consistent with a distributed field model [Hausum, retrieved 2024] [LinkedIn, retrieved 2026]. The commercial flywheel would be straightforward. More buyer volume creates more reports, more reports create a denser defect-and-cost dataset, and a stronger dataset can make broker partnerships more attractive because the service becomes faster and more standardized at the point of transaction. The Berkshire Hathaway HomeServices Spain relationship is the most visible sign that this loop may already be starting [La Vanguardia, August 2024] [Berkshire Hathaway HomeServices Spain, December 2024].
Putting a value on the upside is difficult because no public market-size dataset or direct listed comparable is provided in the sourced material. Still, the shape of the win is legible. If Hausum were to own the inspection step for a meaningful share of Spanish residential transactions and layer software into broker workflows, it could plausibly become a strategic acquisition target for a brokerage, listings platform, mortgage intermediary, or real-estate services group that wants control over pre-transaction risk assessment (scenario, not a forecast) [Idealista, February 2024] [La Vanguardia, August 2024] [Expansión, October 2026]. The public record supports ambition at the company-building level: a reported €500,000 round in October 2026 brought in Diroca and Spicy4Tuna, with the capital earmarked for team growth, technology, and process improvements, which is consistent with a business trying to move from founder-led service execution toward a more scalable operating model [La Vanguardia, October 2026] [Expansión, October 2026] [EU.vc, October 2026]. In plain terms, the upside case is that Hausum turns home inspection from an ad hoc professional service into transaction infrastructure that others distribute for it.
