What’s New…

As the air turns crisp and the pace picks up across the New Nordics, we’re taking a moment to share what’s been quietly but powerfully taking shape. Our new fund is in full swing, with 10 investments already made and more on the horizon. While a few of these new alliances are still under wraps, trust that announcements are coming - and they won’t go unnoticed.

Seasonal shifts don’t slow us down. Whether it’s summer sun or autumn rain, our hunt for the next generation of tech Superheroes never pauses. If you’re building something bold, ambitious, and a little bit crazy - in the best possible way - our door is always open. Reach out, we want to hear from you.

And for those watching from the sidelines: there’s still time to join the ride. We have room for a few final limited partners before the fund closes in Q4. Curious to explore what joining us as an LP looks like? Just reply to this email - we’ll take it from there.

-Superhero Capital, your sidekick when it matter.

Superhero Capital Strategy Session 🧠

Last month in Vilnius, the partners at Superhero Capital gathered for a strategy session - a chance to pause, reflect, and align on where we’re headed next. It was a thoughtful exchange on what drives our success, where we can improve, and how we continue building together.

Later that evening, we took a moment to simply connect as a team - reminding ourselves that beyond capital, it’s trust, collaboration, and shared ambition that drive everything we do.
