Breaking Barriers in Deep Tech: Women, Science, and Startups in Estonia

Deep tech has never been the easy road. It’s slow, demanding, and full of moments where you have to explain your science over and over again just so people get it. But it’s also where real innovation happens, and where founders with persistence and passion can change entire industries.

At Sparkup Tartu Science Park, deep-tech startups have been supported since 2006. Over that time, the team has seen how difficult it can be to take scientific breakthroughs and turn them into business success. But they’ve also seen the huge impact that happens when researchers take that leap and how Estonia’s startup ecosystem has evolved to support them.

Today, Estonia is shaping up to be a serious player in deep tech. Sure, most funding still goes into software and “lighter tech,” but that’s changing fast. The country’s innovation strategy now prioritizes science-based entrepreneurship and Tartu Science Park is proud to be helping lead that shift.

Women Leading the Change

Some of the most inspiring founders Sparkup Tartu Science Park have worked with are women who’ve turned their deep scientific knowledge into scalable businesses.

Heli Valtna, founder of LightCode Photonics, is a perfect example. When she joined their incubation program, her prototype was so big it took four people to move it. Today, after years of development, mentoring, and support, LightCode builds compact 3D vision systems that are shaping the future of robotics and autonomous mobility.

Laura and Glen from GaltTec have followed a similar journey. Their advanced energy technology had been in development for years, but with persistence, strategic mentoring, and the right connections, they’ve now reached a stage where real clients are paying attention. Laura’s energy and drive to promote their work shows that being a young woman in a deep-tech business isn’t just possible, it’s powerful.

Then there’s Grete from Taara Robotics. When she reached out to Sparkup Tartu Science Park, she had just finished her work on the European Space Agency’s ExoMars project. She wanted to see if her space robotics research could be applied on Earth. Today, Taara Robotics is doing exactly that completing multiple ESA projects and piloting real-world applications that merge space engineering with terrestrial needs.

Why Deep Tech Matters

These stories matter because they show what’s possible when science meets entrepreneurship. Deep tech companies don’t just make apps they create entirely new industries. They develop solutions for climate resilience, sustainable energy, smarter manufacturing, and yes, even space exploration.

Yet women are still underrepresented in deep tech, not just in Estonia, but worldwide. The good news is that change is happening. Estonia already has over 200 female-founded startups across sectors, and each year more women step into leadership roles in science-based ventures.

What they need is the right kind of support. Deep tech founders require more than funding they need long-term mentoring, validation, and networks that help them connect science with markets. That’s exactly what Sparkup Tartu Science Park aims to provide: a bridge between research and entrepreneurship.

tartu science park’s Role in the Ecosystem

As one of Estonia’s oldest startup incubators, Tartu Science Park is proud to be at the center of this evolution. Together with partners like the City of Tartu, and ESA BIC Estonia, they help early-stage founders build a path from idea to prototype and beyond.

Their role isn’t just to guide, it’s to listen, adapt, and stand beside founders through the tough phases. Whether it’s a scientist perfecting a prototype, a robotics engineer exploring a new use case, or a startup scaling a deep-tech solution globally, they make sure they don’t walk alone.

Through programs like Sparkup Incubator and ESA BIC Estonia, they’ve also helped deep-tech founders explore opportunities beyond Earth in space, cybersecurity, and dual-use technologies. The lessons learned from space technology often find their way back into everyday industries like logistics, energy, and medicine. That cross-pollination is where the real magic happens.

Estonia’s Deep-Tech Future

Estonia may be small, but that’s what makes it agile. Collaboration happens faster. Partnerships form easily. And deep-tech founders can move from idea to market in months, not years.

We’re already seeing the next generation of scientists many of them women tackling global challenges with confidence. Whether it’s building better sensors, developing cleaner energy systems, or turning space technologies into Earth-based solutions, they’re showing that deep tech is not just for the few it’s for the future.

At Tartu Science Park, they’ll keep doing what they do best standing behind these innovators, connecting research with opportunity, and proving that Estonia can punch far above its weight in the global deep-tech arena.

Because when science, ambition, and courage meet truly transformative things happen.
