JOURNEY
…or how we transformed email advertising one step at a time.

In 2016, Andreas Jürgensen and Anders Rantzau Rasmussen crossed paths in Denmark. One was a tech enthusiast focused on ads, and the other was an email nerd. Driven by shared values, love for innovation, and passion for code, they envisioned merging ad tech with email. And so, Passendo was born.
At the time, no ad tech solutions existed for email. Seeing a gap in the market, they ventured into uncharted territory, creating a groundbreaking tool. Passendo emerged as a pioneer, offering something entirely new to the industry.
Within the first year, it became clear that Denmark's market was too small for their vision. Expanding internationally, Passendo gained recognition from publishing superstars around the globe. Today, if you're in publishing and don’t know Passendo, you’re missing out.
Passendo’s story grew richer with the addition of Serbian developers. The cultural clash between Denmark and Serbia sparked fresh creativity and exciting innovations. Frequent Copenhagen-Belgrade flights and annual gatherings forged a strong, collaborative, and creative bond.
Passendo has evolved from a startup to a thriving scale-up. What keeps the team motivated? The fun, the challenges, and the incredible people they meet along the way. Passendo is now a family, united by a shared passion for innovation and growth.
Passendo serves clients across every continent except Antarctica, proving that its impact knows no borders. With a team of 20+ talented email ad heroes, they continue to make waves in the email advertising ocean.
Passendo’s growth has been fueled by strong relationships with renowned investors, including People Ventures (2019), First Party Capital (2021), and Newion (2021). These partnerships speak for themselves about confidence in Passendo’s vision and success.
