According to Bauhub co-founder Henri Trees, the company’s construction software could one day be used in as many countries as possible.

Construction sites and their behind-the-scenes processes often resemble a bustling anthill – builders, designers, subcontractors, contractors, supervisors, and dozens of other stakeholders are constantly in motion. This, in turn, means massive correspondence, countless drawing exchanges, and endless administration. Bauhub’s construction software aims to bring all these activities into one place, making the building process faster and smoother.

“The construction site is a huge gathering of people and different parties. We want to improve it so that all communication and drawings are in one place,” said Bauhub co-founder Henri Trees in the company’s office on the top floor of a building on Tartu Town Hall Square.

40,000 users

Thanks to Bauhub’s application, builders spend less time on administrative tasks since all stakeholders know exactly where to find what they need, Trees noted.

In essence, it is like a big Facebook group, except that construction-related information is much more organized and easier to manage.

Trees founded Bauhub in 2016 together with three friends – Teet Parts, Marko Leek, and Otto Täht. Their motivation was the outdated administrative processes in construction. “At that time, people mostly used email and to some extent Dropbox,” Trees recalled.

In Estonia, Bauhub is a unique company, though globally there are several similar players. Some focus more on 3D environments, others on drawings. “We’d like to create universal software suitable for all countries, but in reality, markets are very different, as each has its own construction management habits,” Trees admitted. That is why Bauhub has so far focused mainly on the Estonian market.


According to Trees, about 95% of Bauhub’s 40,000 users are from Estonia. The application is also used in other Baltic countries and Finland. “Our users include all parties in the process – from subcontractors and designers to construction supervisors and clients. They all have their place in Bauhub,” explained Trees. He added that all the largest construction companies in Estonia use Bauhub’s project management software.

For example, Tartu’s Delta Centre and the extension of the University of Tartu Sports Hall were built with Bauhub’s support. “I think all the major developments in Estonia have used our application,” he suggested.

Clients keep coming

How is Bauhub affected by the general situation in the construction sector? Trees admitted it is difficult to measure directly, as new users have joined even during difficult times. “We may not feel the effects of crises immediately. For example, during the COVID-19 pandemic or when the war in Ukraine started, we did see a slight decrease in clients, but I cannot draw a clear connection with the state of the construction sector,” the co-founder explained.

Asked about the digitalization of Estonia’s construction industry, Trees said there are both positives and negatives, but overall the situation is quite good. “Of course, there are areas that could be better, but the issue is that Estonians are very practical – they want to get their work done quickly and efficiently,” he noted. This often means there’s little time to adopt new software and change processes. “Someone has to take the initiative to implement the software.”

According to Trees, retaining employees at Bauhub is not particularly difficult – once someone joins, they tend to stay for a long time. “We give people a lot of freedom and, at the same time, responsibility,” he explained.

When hiring, the company prefers people who, in addition to professional skills, share common interests with the rest of the team and enjoy spending time together outside of work. “I wouldn’t say we’re a family, but most of us were already friends before joining Bauhub,” Trees said.

Today, Bauhub employs 13 people. Most of them come to the office three to four days a week, even though in an IT company it wouldn’t matter whether someone worked from the forest or the office – as long as they have a computer and an internet connection. Since Tartu is a relatively small city and the office is easily accessible, in-person communication is much simpler.

Together with the Finns

How does Trees evaluate Tartu’s IT environment? “Even when I was a student, the development was very good, and it has continued since then. A lot of young people are coming in,” he said.

Bauhub has ambitious plans for the future. At the end of last year, the company was sold for six million euros to Admicom, a Finnish publicly listed company that also develops construction software. Trees expressed hope that joining Admicom would eventually lead to Bauhub becoming a platform that integrates both Admicom’s and Bauhub’s services.

“The vision is for Bauhub to be the central manager of all the information generated on construction sites, and for it to be used in as many countries and regions as possible,” Trees said of the company’s future goals.

Thus, the anthill-like bustle of a construction site could become many times smoother if everyone knows exactly where to find the information they need.
