COS Systems buys Fiber Flow in Nordic broadband push

COS Systems acquired the Fiber Flow software platform from Vinnergi and Bitvis as part of a new strategic partnership aimed at expanding the companies’ reach across the Nordics and Europe. The deal gives COS more automation and provisioning tools for broadband operators while keeping Vinnergi in charge of customer-facing work in the Nordic market.

Why it matters: - The deal strengthens COS Systems’ position in broadband software by adding a major Nordic BSS/OSS platform with more than 400,000 active subscribers. - COS Systems gains deeper automation for Active Ethernet networks, a technology still widely deployed even as PON becomes the dominant access standard. - The transaction could make it easier for operators to manage a shift from Active Ethernet to PON with fewer manual steps. - Vinnergi keeps its role as a local delivery partner, which helps preserve existing customer relationships while broadening the combined offering.

What happened: - COS Systems and Vinnergi announced a strategic partnership on September 8, 2026. - As part of the agreement, COS Systems acquired the Fiber Flow software platform from Vinnergi and its subsidiary Bitvis. - Fiber Flow currently supports more than 400,000 active subscribers across nearly 30 networks in the Nordic region. - COS Systems said it will assume responsibility for continued development of Fiber Flow. - Vinnergi will remain the customer-facing partner in the Nordic market for sales, implementation, integration and support. - Vinnergi will also gain access to the full COS Systems product portfolio.

The details: - Fiber Flow is one of the major BSS/OSS platforms in the Nordics. - The acquisition expands COS Systems’ network management and provisioning capabilities, especially for Active Ethernet access equipment. - COS Systems already provides a cloud-based BSS/OSS platform for broadband operators, including COS Business Engine, COS Wholesale Engine, COS FSM, COS Prospector and COS Marketplace. - COS Systems also serves municipal broadband networks, regional service providers and Tier 1 carriers. - Vinnergi is a Swedish engineering and technology consulting company with experience in fiber network development and operations. - Vinnergi sells and implements Fiber Flow across the Nordic market and has a particularly strong position in Sweden. - COS Systems was founded in Umeå and has expanded globally. - Vinnergi is headquartered in Linköping, has offices in around 20 locations, employs more than 600 people and turns over approximately SEK 900 million. - Vinnergi’s business is organized into four areas: Communicate, Power, Living and Construction. - Vinnergi is partly employee-owned, and its majority owner is Polaris.

Between the lines: - Mikael Philipsson said the acquisition marks the beginning of a broader investment in the European market. - Philipsson said COS Systems built its first platform for Swedish Open Access networks nearly 20 years ago before expanding to North America. - The partnership gives COS Systems a stronger European footprint while allowing Vinnergi to keep its embedded operating model in the Nordics. - Pierre Wallgren said the Fiber Flow work with Sweden’s municipal networks will continue as before, with the same points of contact, agreements and support. - Wallgren said the partnership lets Vinnergi expand its offering across the Nordics and Europe through COS Systems’ portfolio.

What's next: - COS Systems will continue developing Fiber Flow as part of its broader software platform. - Vinnergi will keep handling customer-facing delivery in the Nordic market. - The companies plan to use the partnership to reach more networks across the Nordics and Europe. - COS Systems will fold Fiber Flow into a wider product suite aimed at automation, subscriber management and field operations.

The bottom line: - COS Systems gets a proven Nordic broadband software asset, and Vinnergi keeps the local execution role that gives the platform market access.
