A Spanish construction company's estimating department works from a stack of documents: PDF plans, IFC building models, and BC3 budget files. The process of extracting measurements, mapping them to trades, and checking for errors is manual, slow, and prone to costly mistakes. Constrik, a Barcelona-based startup founded in 2026, is betting its AI platform can read those documents and automate the entire tender preparation workflow [Constrik, retrieved 2026].
The workflow wedge
Constrik's product is narrowly focused on the pre-contract phase, specifically the work of estimators and tender departments. The software ingests the standard file formats used in Spanish construction, extracts quantities, and automatically assigns work items to the appropriate trades like masonry or electrical [EU-VC, October 2026]. Its core promise is to shorten bid cycles and reduce errors by performing automated checks for missing or duplicated items. The platform also compares proposed prices against a contractor's own historical data, a feature the company calls its "memory",a continuously updated database of past budgets and signed contracts [PERPLEXITY SONAR PRO BRIEF, retrieved 2026]. This positions the tool not just as a one-off analyzer but as a system for centralizing a company's institutional pricing knowledge.
Founder Octavi Uyà's pivot to proptech
The company is led by solo founder Octavi Uyà, who brings a mix of entrepreneurial and corporate finance experience. He was previously co-founder and CEO of Nautal, a boat rental platform, and is also CEO and co-founder of Woodea, a sustainable construction firm [The Org, retrieved 2026]. His background includes a managerial role in financial advisory at Deloitte [Woodea, retrieved 2026]. This path from corporate finance to founding marketplaces and now a deep-tech construction tool suggests a pattern of identifying and digitizing inefficient, paper-heavy processes. The recent €350,000 pre-seed round, led by Madrid-based Plus Partners, is earmarked for hiring the company's first commercial specialist, an implementation engineer, and a full-stack developer [El Referente, October 2026].

Early traction and the path to scale
Constrik has begun its commercial rollout with at least one named implementation at construction firm San Martín and has completed a pilot with a large, unnamed Catalan construction group [El Referente, October 2026]. The company is targeting mid-sized and large Spanish residential builders, pricing its platform at approximately €250 per active project per month [El Referente, October 2026]. This project-based pricing aligns the cost directly with a contractor's revenue-generating pipeline, a model that should be easy for customers to justify if the tool delivers on its speed and accuracy promises.
The technical breakdown is straightforward. The platform parses structured (BC3, IFC) and unstructured (PDF) data, uses computer vision and natural language processing to identify elements, and then applies rule-based logic for trade assignment and error detection. The more complex long-term challenge is data quality and model generalization. A contractor's historical data must be clean and well-structured for the price-comparison "memory" to be valuable. Furthermore, construction methodologies and regional pricing can vary significantly across Spain.
The sober assessment for scale hinges on two factors. First, the sales motion requires convincing traditionally conservative construction firms to trust an AI with their most sensitive commercial data,their actual costs and bid strategies. Second, the €250-per-project price point means Constrik needs a high volume of active projects per customer or a very large number of customers to reach meaningful SaaS revenue. A slowdown in Spanish residential construction starts would directly impact the company's growth ceiling.
