Austria’s Sodex Innovations secures €4 million to scale automated construction-site surveying

ConTech startup Sodex Innovations , a Vorarlberg-based innovator of automated surveying and documentation of construction sites, infrastructure projects, and mines, has successfully closed a funding round of €4 million to accelerate the company’s next stage of development.

The round was led by Capmont Technology, with participation from Bloomhaus, Look AI Ventures, and German business angel group Superangels. Existing investors SOSV, OMA, and 12 Rounds Capital (Katharina Klausberger and Armin Strbac) are investing again.

“ Real-time updates directly from the construction site have become a central starting point and are now indispensable for many of our customers. With this funding, we can not only expand our team but also our portfolio and scale internationally much more quickly, ” says Ralf Pfefferkorn , CEO and co-founder of Sodex Innovations.

Sodex Innovations’ round follows approximately €60 million in disclosed 2026 funding as seen by EU-Startups across construction software, building technology, site-adjacent industrial systems and geological data platforms.

Comparable announcements include €1.3 million for German AI ConTech platform conmeet , €14 million for Milan-based seismic-protection company ISAAC antisismica and €7.4 million for British-US real-estate software startup Build , alongside investments in lower-carbon construction materials and AI-assisted mineral exploration.

Austria also produced an adjacent round, with Vienna-based sequestra raising €3 million to scale industrial CO₂ mineralisation. Including Sodex, the selected rounds represent roughly €64 million.

In adjacent activity, EU-Startups reported in 2024 on lead investor Capmont Technology’s €100 million early-stage B2B technology fund .

Michael Wittner , partner at Capmont Technology, adds: “ For the first time, Sodex makes physical construction activity measurable and controllable in real time, thereby creating the data foundation on which the industry will be managed in the future.

“ We believe that a combination of hardware, software, data, and AI – which enables these sectors to achieve a real leap in productivity – is not only incredibly exciting but also long overdue .”

Founded in 2021, Sodex is developing AI-powered technology that automatically surveys and digitally maps construction sites, mines, and infrastructure projects while they are in operation – their current user-base sits at over 100 across the U.S., Australia, and Europe.

Construction machinery acts as mobile data collectors, recording terrain, material movements, and progress, which are fed directly into the Sodex web platform. There, documentation, quantity calculations, and progress analyses are available, making construction sites simpler, faster, and more transparent.

For customers, this potentially means fewer manual measurements, fewer delays caused by missing data, and better decisions based on solid data.

In an industry that is under increasing pressure from margins, schedules, and documentation requirements, Sodex says they provide a direct way to boost efficiency and improve predictability.
