Constrik, a Spanish company selling AI software to construction firms’ estimating departments, has closed a €350,000 pre-seed round led by Plus Partners, according to Spanish startup press. El Referente reported the round; El Ecosistema Startup followed on 16 October. We could not open El Referente’s page ourselves, so the details below come from the Ecosistema Startup report and Constrik’s own website.
This is a small round, and it is worth reading as one. The Ecosistema Startup report names Plus Partners as the lead and no other investor, and gives no valuation.
What Constrik Sells
Constrik Intelligence, S.L. is registered in Castelldefels, near Barcelona. Its website describes “an AI platform for builders’ estimating departments” (our translation) and says it was designed for Spanish residential contractors. The stated pitch is shorter study times, centralised company knowledge and fewer errors in tenders.
The site lists seven tools that share the same BC3 file and model, among them a tender agent, a price database built from a firm’s own past budgets, a PDF drawing analyser, an IFC clash detector and an auditor for budget files. It works with the BC3 format, a standard Spanish construction-budget file, plus IFC models and PDF plans. Pricing is a fixed annual fee based on how many studies a firm runs, with an indicative figure of about €250 per study before VAT. Those are the company’s published terms.
Ecosistema Startup describes the problem as the stage before a bid: before committing to a fixed price, a builder’s estimating team reviews projects drawn up by others, measures quantities, requests prices from suppliers and subcontractors and looks for errors, often with small teams and knowledge held by two or three people.
Octavi Uyà, whom Ecosistema Startup identifies as Constrik’s founder and chief executive, is quoted there saying (our translation) that the estimating department “is where a builder’s margin is really decided, and yet it still runs on twenty-year-old tools.”
Who Is Using It
The report says the technology is already running at two construction firms: a completed pilot at a large Catalan construction group, which it does not name, and the start of a rollout at San Martín, described as a company with more than a century of history. We could not identify which San Martín that is or find the company’s own confirmation, so we are reporting the name as the press has it and not linking to a company. The Constrik homepage we read names no customers.
The Market Gap
Ecosistema Startup frames the round around a low adoption figure. It traces to Spain’s national statistics institute: INE’s survey of ICT use in companies puts AI use at 11.4% of construction firms in the first quarter of 2025, against 17.5% in industry, 25.7% in services and 21.1% overall. INE’s section is for companies with 10 or more employees. The figures are from 2025, so they describe the market before this round, not today.
The Money and the Investor
Per Ecosistema Startup, the proceeds pay for three first hires: a salesperson with sector experience, an implementation engineer and a full-stack developer. The target customers are mid-sized and large builders. A team that small, selling to firms whose own estimating knowledge is the product’s raw material, makes implementation work the real constraint, and that is our analysis, not a company statement.
Plus Partners is a pre-seed and seed fund co-founded in 2024 by Enrique Linares and Oriol Juncosa; Linares’ page on the fund’s site says he co-founded it that year, and TechCrunch reported its launch in June 2024. Its site lists three areas of interest: Health & Nutrition, Money & Property, and Work & Productivity. Ecosistema Startup quotes Linares as saying (our translation) that the construction sector “is not transformed by outsiders but by people who have worked inside it for years.”
Where This Sits
Estimating and tendering has been a busy corner for funding this autumn. Quotr raised $4 million for takeoff, estimating and bidding. Kuro raised €10 million for German-speaking contractors, and Volve is building checks across tender documents in Norway.
Constrik is the smallest of those and the most local. Its product is built around a Spanish file format and, on its own site, around Spanish residential builders, a narrower market than the others aim at. That is a strength if the format and the buyer are the moat, and a limit on how far €350,000 can reach. Our read: the next thing to watch is whether the two reported deployments turn into paid annual fees, which would be the first public sign that the per-study pricing holds.
