Unwrap the 2025 COS Advent Calendar: Practical goodies for fiber teams, every day 🎁

It is the holiday season — and this year’s COS Advent Calendar is packed with hands-on treats your team can actually use. Every day until Christmas, we’ll drop a bite-size resource you can put to work right away: fun videos, real-world case studies, seasonal playbooks, whitepapers, and more. Kick off with a hello from Isak & Maren, then dive in!

What’s inside (and why you’ll care)

• Do-this-today how-tos. Clear guides for the work you do daily — so operators and admins can move fast with confidence. 

• Seasonal playbooks. Practical scripts to run timely campaigns—like holiday promotions in the customer portal.

• Case studies & spotlights. Stories from operators and partners showing what’s actually working—demand aggregation tactics, offer design, and how open-access models lift take rates without increasing headcount.

• “What’s new” product tour. A crisp overview of updates that smooth daily work

• Industry context, made simple. We zoom out with white papers and explainers so your roadmap stays aligned with where the market is headed—without the jargon.
