Julija’s journey into PR wasn’t intentional—she originally planned to become an investigative journalist. A chance conversation with a top journalist led her to explore public relations, a field she knew little about at the time. This unexpected pivot eventually shaped her career, proving that seizing opportunities and networking can lead to new and exciting paths.

Unlike large corporations, startups don’t have an established reputation to manage—they need to build it from the ground up. This requires a different PR strategy, one focused on storytelling and visibility. Julija realized there was a gap in the market for PR agencies that understood startups' unique challenges, which led her to launch Black Unicorn PR. Her agency helps founders navigate media relations, positioning them in top-tier publications.

Not all PR agencies are the right fit for startups. Julija emphasizes that founders should look for agencies that manage expectations realistically and prioritize long-term brand building over quick media hits. A good PR agency will be honest about what’s achievable and won’t promise instant results. Chemistry between the founder and the agency is also key—without trust, effective collaboration is impossible.

With AI tools becoming more common, many feared that PR professionals would be replaced. However, Julija believes AI can enhance productivity but can’t replace human creativity and relationship-building. While AI can help with grammar checks and basic content generation, PR remains a deeply human-driven industry, relying on authentic storytelling and journalist connections.

Julija’s career highlights the importance of networking—not just for sales, but for long-term opportunities. She advises founders to attend industry events with an open mindset, rather than a transactional approach. Building relationships naturally, rather than aggressively pitching, often leads to valuable connections that can pay off years down the line.

PR is a long game, and startups that approach it strategically—by focusing on storytelling, authenticity, and the right partnerships—can build a strong reputation that supports their growth.

One of TechChill’s main goals is to inspire and support new startup founders in the Baltic region. With over €60 million in new funding available, there’s never been a better time for entrepreneurs in Latvia and beyond to launch their ideas. TechChill is positioning itself as a key player in guiding these founders by providing expert-led content on business growth, funding, and scaling strategies.

While TechChill has always prioritized startups, the event has refined its focus on delivering content that directly benefits founders. From sales and marketing to tech and funding, each aspect of the event is designed to help early-stage companies grow. By packaging these insights into accessible sessions, TechChill ensures that attendees leave with actionable knowledge.

TechChill is more than just a once-a-year event. Throughout the year, the organization promotes Baltic startups internationally, helping them gain exposure in key markets like San Francisco and Helsinki. By connecting founders with investors and global tech leaders, TechChill plays a crucial role in strengthening the region’s startup ecosystem.

TechChill’s attempt to expand into Milan was an eye-opening experience. While the event was well-received, it highlighted the importance of having strong local partners to build a lasting community. Cultural and business differences also played a role, making it clear that successful ecosystem building requires deep local engagement. This experience reinforced TechChill’s commitment to focusing on the Baltics while selectively exploring high-impact collaborations.

TechChill has also taken an active role in supporting Ukraine’s startup community. Recognizing Ukraine’s strong talent pool and growing entrepreneurial spirit, TechChill has facilitated connections between Baltic and Ukrainian founders, investors, and community builders. Their efforts, including trips to Kyiv and partnerships with local stakeholders, aim to create meaningful opportunities for Ukrainian startups despite ongoing challenges.

TechChill’s evolution reflects a broader mission: to make the Baltics a thriving hub for innovation. By fostering new startups, offering hands-on learning, and expanding international connections, it continues to shape the future of the region’s tech ecosystem.

PlanA was created to bridge the gap between climate science and actionable business strategies. In 2017, few businesses understood the importance of sustainability, and there were minimal regulations to guide them. PlanA emerged as a platform that helps companies align their growth with environmental responsibility, demonstrating that sustainable practices can drive success.

PlanA’s platform uses extensive data analysis to offer businesses tailored sustainability strategies. The software not only identifies opportunities for improvement but also provides actionable steps to implement changes. Advanced AI technology ensures that even when data is incomplete, accurate projections and recommendations are made to guide companies in their decarbonization efforts.

The concept of the carbon bubble highlights the overvaluation of fossil fuel companies due to changing legislation and increasing climate costs. This poses risks for businesses and financial institutions relying on outdated assets. PlanA works with its clients to reduce these risks by providing financing and tools to transition toward more sustainable operations.

PlanA goes beyond helping businesses meet regulatory requirements by fostering a culture of sustainability that drives innovation. The platform enables companies to identify cost-saving opportunities while improving their environmental performance. It demonstrates that sustainability is not just about compliance but also a pathway to long-term growth and competitiveness.

PlanA’s approach to sustainability showcases the transformative power of innovation and the urgency of addressing climate challenges through actionable solutions. Its commitment to aligning business strategies with environmental goals is a blueprint for a sustainable future.

Tom Henriksson, a seasoned venture capitalist and General Partner at OpenOcean, began his career in the 1990s when Finland’s startup ecosystem was in its infancy. At the time, the region had limited global tech presence, but it has since grown into a leader in STEM education and data-driven innovation. Today, the Nordics are known for producing companies that excel in analytics and automation, leveraging their strong foundation despite a relatively small population.

OpenOcean, a venture capital firm founded in 2010, specializes in supporting data-intensive business software startups in Europe. With its origins tied to the success of MySQL, the firm emphasizes helping entrepreneurs turn small-scale ideas into globally scalable enterprises. The team has built its reputation on fostering innovation in industries that rely heavily on data.

The podcast highlighted the challenges enterprises face in adopting artificial intelligence technologies. OpenOcean supports startups that simplify AI integration by creating tools and solutions that streamline processes and reduce the need for specialized expertise. One example discussed was a company leveraging AI to improve product launches by predicting success and optimizing strategies.

An annual poker tournament hosted by OpenOcean during the Slush conference has become a memorable tradition. This informal event combines networking with a relaxed environment, fostering connections within the global startup ecosystem. While it adds a playful twist to the conference, it also serves as a platform for meaningful professional interactions.

By blending a focus on data-intensive startups with a deep commitment to the Nordic ecosystem, Tom Henriksson and OpenOcean continue to shape the future of venture capital.

Launching Pokémon GO was a milestone in Mathieu’s career. Despite starting with a small team of just 35 people, the game became a cultural phenomenon, achieving over a billion downloads and generating substantial revenue. Mathieu attributes this success to visionary leadership and close collaboration between engineering and business. “What makes the difference between visionaries and others,” he said, “is the ability to think big, even with a small team.”

At LVMH, Mathieu’s focus is on applying AI across the product lifecycle—from conception to after-sales services. He shared an example of AI enhancing customer relationships: “Imagine a co-pilot for sales associates at Tiffany’s, connecting past purchases and life events to suggest the perfect next product. This is where the algorithm becomes a creative enabler.” Such applications of AI underline the potential for blending personalization with luxury.

Mathieu emphasized that innovation in luxury requires a delicate balance of tradition and technology. At LVMH, efforts include creating digital twins for products and combating counterfeiting with blockchain technology. The group also explores immersive experiences to elevate customer satisfaction in stores. “Luxury is about the invisible—the serotonin you feel when you buy a dream,” Mathieu explained, underscoring the subtle, emotional elements of high-end retail.

Reflecting on his career, Mathieu highlighted the importance of resilience, citing the story of Ernest Shackleton as an inspiration. He also championed the value of openness to new ideas and experiences, saying, “Being open to nature and innovation constantly drives me.” His advice to entrepreneurs and innovators? Stay focused, remain curious, and always be willing to adapt.
