“It was really nice and pleasant to see some really big issues being raised,” she reflected. “Topics like hate speech and handling death were approached in ways we hadn’t necessarily considered from a business perspective before. I also saw a strong focus on language learning, which is clearly a global need. Every pitch brought something unique, which made it difficult for us to decide—it was a truly thought-provoking evening.”

The judges weren’t the only ones impressed. Programme Manager , who had worked closely with the teams since May, expressed his pride in the participants. “Congratulations to you all,” he said. “You’ve done amazing work—step by step, you’ve built something meaningful.

The challenges pushed me to grow, and I feel more confident about what Good Grief! can accomplish now.”

The team behind Juniper, a platform for sustainable team-building activities, credited their mentor, , for helping them move from concept to reality. Co-founders Venla Hakunti, Anni Lyytikäinen, and Lotta Wilkman described Sara as a guiding light throughout the process.

“We don’t know where we’d be without Sara,” Venla said. “She gave us structure, helped us take one step at a time. We started with just an idea, and now we have a product. That’s something we’re incredibly proud of.”

Sara Mattila, an impact entrepreneur and sustainability researcher, has been a dedicated mentor to many TREMOR teams. Reflecting on her role, : “Having someone in your corner, especially during uncertain times, can be invaluable. It's about believing in someone's potential, even when they can't see it themselves."

The Juniper team highlighted how crucial this support was. “We had nothing when we started,” Venla added. “Now we have something tangible. Sara didn’t just guide us—she believed in us and gave us the confidence to move forward.”
