“Our engineers today are equipped with can-do attitudes and an ability to create ingenious and secure solutions and integrations.”
Estonia’s reputation as a digital powerhouse owes much to its innovative companies, and Proekspert is no exception. Founded in 1993 during a time of economic uncertainty, this software development firm seized the opportunity to pioneer ground-breaking solutions in the newly independent nation. Today, Proekspert stands as a testament to Estonian resilience and entrepreneurship, shaping the future of industrial IoT and embedded software engineering on a global scale.
The Spark of Ingenuity
In the early 1990s, Estonia’s business landscape was a blank canvas. For Proekspert’s founding member, Vambola Kotkas, this presented a rare moment. “We saw an opportunity in the newly independent Estonian market, grabbed it, and started a software development company. We had ideas to offer, and customers started to appear to need software solutions,” recalls Vambola. The company’s first significant breakthrough came with the development of the Raekaart, one of Europe’s first smart card systems. This ambitious project cemented Proekspert’s reputation as a trailblazer and laid the foundation for the Estonian Bank Card Center system. “It was ahead of its time,” Vambola notes, reflecting on the bold vision driving Proekspert today.
Engineering Excellence: The Foundation of Success
The key to Proekspert’s sustained success lies in its unwavering commitment to engineering excellence. CEO Marko Spielmann highlights this as the company’s defining characteristic: “Proekspert has always been a place where complex problems meet practical solutions. Our engineers don`t just write code – they solve business challenges with technology.” This ethos of problem-solving and critical thinking has been instrumental in shaping Proekspert into a trusted partner for manufacturers worldwide. Its custom software solutions cater to diverse needs, from device-to-cloud connectivity to compliance with stringent cybersecurity standards like the EU Cyber Resilience Act. “By focusing on specialized expertise, we can move fast and deliver solutions that are both efficient and cost-effective.”
Pioneering IoT Solutions
Proekspert has developed a reputation for tackling some of the most challenging projects in the IoT space. A shining example is its work with Solarstone, an integrated solar roof manufacturer. By introducing an AI-based remote measurement solution, Proekspert transformed Solarstone’s sales pipeline. A testimonial shared by Solarstone notes: “The solution’s ability to capture roof measures within seconds, with reasonable accuracy, has revolutionized our sales process.” The results speak for themselves: lead conversion rates skyrocketed to an impressive 60-99%. For Proekspert, innovation isn’t just about delivering results and building meaningful partnerships. Its collaborations with industry giants like Microsoft, Microchip, and Beckhoff ensure that its solutions remain at the cutting edge of technology, offering unparalleled value to device manufacturers.
An Estonian Advantage
As an Estonian company, Proekspert benefits from the country’s unique digital ecosystem and culture of resourcefulness. “Historically, the Estonian people have had to find solutions when faced with very limited resources,” explains Marco. “Thanks to this, our engineers today are equipped with can-do attitudes and an ability to create ingenious and secure solutions and integrations.” Estonia’s compact size and status as a digital state make it an ideal testing ground for new ideas. This advantage, combined with Proekspert’s ability to embed itself as part of its clients’ teams, has made it a preferred partner for solving complex challenges globally. As one client puts it, “Proekspert team’s understanding of complex manufacturing environments and ability to deliver solutions that can be implemented fast has been one of the key elements in our successful long-term partnership.
Responsibility and Sustainability at the Core
In 2025, Proekspert was recognized by the Responsible Business Forum, earning the silver label for its commitment to sustainability. For Marco, this milestone is a source of pride and motivation: “Sustainability is not just a label for us — it’s a responsibility. The recognition confirms we’re on the right path, but more importantly, it challenges us to integrate sustainable thinking into every decision we make.” This commitment extends beyond environmental concerns to encompass a holistic approach to responsibility. Proekspert’s Net Promoter Score of 68 is a testament to its ability to build lasting client relationships by consistently delivering innovative and impactful solutions.
The Future of AI and Automation Proekspert is not content to rest on its laurels. The company is actively exploring new frontiers in AI and machine learning, focusing on developing custom solutions tailored to client needs. From AI incident reporting tools to automated routine tasks, Proekspert is pushing the boundaries of what’s possible in software development. “AI and automation are not just about efficiency, they empower us to guarantee higher functional reliability and are about creating smarter, safer, and more user-centric products. Our role is to help clients turn these technologies into real value for their businesses and their customers,” says Marco. This proactive approach ensures that Proekspert remains a leader in its field, continuously adapting to the industry’s evolving demands.
Proekspert: A Partner in Progress
For over three decades, Proekspert has been at the forefront of innovation, combining technical expertise with a deep understanding of its clients’needs. Whether pioneering new IoT solutions or setting the standard for responsible business practices, Proekspert exemplifies the best of Estonian resourcefulness. As the company looks to the future, its vision remains clear: to build smart, secure, and sustainable solutions that empower its clients and drive progress on a global scale. As one of its clients eloquently says, “Besides being highly skilled software architects, designers, and developers, they also react very swiftly when critical situations require attention.” Proekspert is more than just a software development company—it’s a catalyst for innovation, a partner in progress, and a shining example of what’s possible when engineering excellence meets a culture of responsibility.
