Case Study: How Mercell grew its ARR 10 times in 5 years

Christine Hammeren
Marketing Manager

Mercell is the leading European digital platform for public procurement and tender management, connecting public-sector buyers with suppliers across multiple markets.

ARR: NOK 85m to 838m
Enterprise Value at exit: NOK 4.8bn
Period: 2018–2022
EV Growth: 27 X
Outcome: Public-to-Private sale to Thoma Bravo at a 110% premium

When Viking Growth became the largest shareholder in 2018, Mercell was already a leading Nordic player. The strategy focused on building Europe’s top procurement marketplace through mergers and acquisitions.

Terje Wibe, CEO of Mercell

The Starting Point

Mercell operated a classic two-sided marketplace:

  • Public buyers on one side
  • Suppliers on the other

The platform had strong Nordic traction, but:

  • Geographic expansion was required to scale
  • The management team wasn’t experienced in scaling in Europe
  • Growth depended on maintaining a balance between buyers and suppliers

Marketplace dynamics leave limited margins for execution errors.  

The Growth Strategy

Mercell’s growth relied on three pillars: strengthening the management team, disciplined M&A execution, and pricing models based on genuine network effects.

1. Building the Leadership Capacity for Scale

Before accelerating growth, Mercell intentionally rebuilt its management team, establishing new senior leadership roles across key functions.

  • Product
  • Technology
  • Sales and Marketing
  • HR
  • Finance


This expansion of leadership depth established the operational and organizational capacity necessary to scale effectively, both organically and through acquisitions.


Key insight:
Growth doesn’t stall because of strategy; it stalls because leadership bandwidth becomes constrained.


2. Scaling a Dual-Sided Marketplace Through M&A

Mercell’s M&A strategy was designed to support geographic expansion by establishing a leading position on both sides of the marketplace, buyers and suppliers, within each new country. In practice, this often meant securing dominance on one side first, then systematically building the other.

In Finland, the supplier market was not yet fully developed. The acquisition of Cloudia, therefore, gave Mercell a leading position on the buyer side, creating a strong foundation for subsequent organic growth in supplier participation and monetization.

Over a five-year period, Mercell:

  • Acquired 12 companies
  • Entered 5 new countries
  • Expanded both geographic footprint and product depth

Key insight: In marketplace businesses, balance matters more than volume. Growth on one side must enable, and be enabled by, growth on the other.

3. Integration as a Core Competence

Completing 12 acquisitions in just over two years required discipline extending beyond deal execution. Mercell regarded integration as a core organizational capability rather than a post-transaction consideration.

Each acquisition followed a structured and repeatable integration sequence:

  1. Alignment of finance and reporting
  2. Integration of technical systems
  3. Harmonization of sales, marketing, and long-term value creation initiatives
  4. Execution of cost- and revenue synergies

Although these processes required significant organizational effort, they were essential for maintaining operational stability, preserving strategic focus, and sustaining growth momentum.

Key insight: M&A success is determined after closing, not at signing.

4. Pricing and Value Creation Through Network Effects

Organic growth depended on continuously strengthening Mercell’s value proposition for both buyers and suppliers. Key elements included:

  • Stronger products increased customers' willingness to pay
  • Network effects reinforced pricing power
  • Pricing strategy became a deliberate growth lever

Viking Growth provided pricing expertise to Mercell, facilitating the translation of platform value into annual recurring revenue growth.

Key insight: Pricing power follows value, not the other way around.

The challenges

Rapid expansion introduced significant operational and organizational strain:

  • A heavy integration workload across multiple acquisitions
  • Extended hours and demands on finance, technology, and commercial teams
  • Increased complexity from managing operations across numerous countries

Scaling a dual-sided marketplace at this pace required both organizational resilience and a high degree of internal trust to maintain momentum and execution quality.

The Role of Viking Growth

Viking Growth acted as an active owner throughout the journey.

  • Served as an engaged Chairman throughout the entire ownership period.
  • Close board involvement through critical phases
  • Supported the management team build-out
  • Projects and sparring on pricing and growth strategy
  • Active leadership in all M&A activities, including sourcing, diligence, and integration
  • Raised both debt and equity to fund acquisitions
  • Led the process to acquire and delist EU Supply from the London Stock Exchange
  • Led the company’s IPO on the Oslo Stock Exchange in 2020
  • Oversaw the public-to-private process culminating in Mercell’s sale to Thoma Bravo

“Viking stands out through their unique combination of subject-matter strength, hands-on operational experience, and genuine human connection.”

— Terje Wibe, CEO, Mercell

The Outcome

During Viking Growth’s ownership period, Mercell:

  • Grew ARR 9×
  • Completed 12 acquisitions in 5 countries
  • Raised €270m in equity and €200m in debt
  • Was acquired by Thoma Bravo at a 110% premium

CEO Takeaway

Mercell didn’t scale by chasing growth on all fronts.

It scaled by:

  • Respecting marketplace dynamics
  • Building leadership capacity early
  • Using M&A to unlock network effects
  • Turning value into pricing power
