about us
The team behind Bandboss Manager: combining design, code, and a shared love for live music to build the tool your band needs.
Meet The Boss: Tessa Nicolai
Hi! I’m Tessa Nicolai (43), the straight-talking brains behind Bandboss Manager. My mission is to take the stress out of an artist’s life through logistics, strategy, and design.
Based in Zwolle, I co-founded this venture with my fiancé, Ronnie van Doorn. I started by making bands stand out online with www.bandbosswebdesign.nl, and today I still use those skills to create professional websites for my clients.
Managing a busy home with Ronnie, our three kids (8, 8, and 9), and our cats Karen, Sjonnie, and Anita, has made me an expert at organizing chaos and hitting deadlines.
My happy place? Front-row at a festival or on my Royal Enfield. I’ll handle the business side, so you can focus on creating and performing!


Meet The Architect: Ronnie van Doorn
Hi, I’m Ronnie van Doorn (42), the developer behind the Bandboss Manager app. Together with my fiancé Tessa, I focus on a simple mission: making software less boring and more human.
With a background in UX, development and management, I bridge the gap between user needs and business goals. This ensures Bandboss Manager isn’t just functional, it’s intuitive and fast.
Life at home in Zwolle with our three kids (8, 8, and 9) and three “supervising” cats is the perfect training ground for building apps: managing chaos, setting clear boundaries, and making sure things just work.
When I’m offline, you’ll find me at concerts/festivals, riding my Indian power cruiser, or gaming (mostly on the PS5).
