Most people don’t think about pest control when they hear the words “private equity.” But if you look closely at what Klar Partners Ltd is doing with Oleter Group across Northern Europe, pest control is actually one of the key reasons the whole strategy works so well.
This article explains what a roll-up strategy is, who Klar Partners and Oleter Group are, how they grew from two countries to four in just a few years, and why pest control plays a bigger role than you might expect.
Who Is Klar Partners Ltd?
Klar Partners Ltd is an independent, mid-market private equity firm investing in Northern Europe, with a focus on the Nordic, Benelux, and DACH regions. In simple terms, a private equity firm invests money into businesses to help them grow, then earns a return from that growth.
Klar makes control investments in companies providing mission-critical products and services, partnering with management to build sustainable, market-leading businesses through a responsible investment approach. The firm targets mid-sized companies with revenues roughly between €50 million and €500 million.
With the closing of Fund II, Klar has raised €1.5 billion since inception. That shows strong confidence from investors who believe in their long-term approach.
What Is Oleter Group?
Oleter Group consists of Ocab and Frøiland Bygg Skade, market-leading providers of property damage restoration services. The service offering includes damage inspection, pest control, and restoration of fire and water damage.
When Klar invested in September 2021, Oleter had close to 1,700 employees in 90 locations across Norway and Sweden, with 2020 sales of approximately SEK 2 billion.
What many people miss is that pest control was always part of Oleter’s core offering, not something added later. This is important to understanding why the strategy works.
What Is a Roll-Up Strategy?
A roll-up strategy means buying several smaller companies in the same industry and combining them into one larger, stronger business. Instead of building from zero, you find companies that already work well locally, bring them under one roof, and create a network that serves more clients, in more places, at a higher standard.
Think of it like several local bakeries joining one group. Each still bakes for its own neighborhood, but now they share buying, training, and management. The result is better quality at a lower cost.
Klar used the standard private equity approach: establish a platform, bolt on regional players, carve out non-core assets, professionalize management, and chase the next deal.
How the Strategy Grew, Step by Step
After Klar invested in 2021, the growth was deliberate and steady.
2022 Sharpening the Focus
In 2022, Klar separated the underground infrastructure maintenance business into a standalone company. The UIM operations merged with Swoosh, forming a SEK 500 million business. The move sharpened Oleter’s focus on its core restoration services while giving the UIM business room to pursue its own consolidation strategy.
2023 Entering Denmark
The first major geographic move came in 2023 when Oleter entered Denmark through Trinava Skadeservice Danmark. This gave the group a real foothold in a new market for the first time.

2024 A Year of Major Expansion
By June 2024, the company added Dansk Industri og Skadeservice Vest, creating enough scale to rebrand the combined Danish operations as ISV/Trinava.
Finland followed later in 2024, when Ocab acquired VV-Kuivaus Group Oy, adding six offices and 120 employees with EUR 15 million in annual revenue.
In January 2024, Oleter also bought Bygg og Skadeservice AS in Norway, adding approximately NOK 45 million in annual turnover and 35 employees. This acquisition was notable because it converted a former franchise relationship into a fully owned operation, completing Oleter’s coverage of Northern Norway.
The property damage restoration company now operates across four Nordic countries with 2,200 employees, up from 1,700 staff working in just Sweden and Norway when Klar invested in September 2021.
Why Pest Control Matters in This Strategy
You might wonder why pest control fits inside a property restoration business.
The answer is simple: pest infestations are property damage. When rodents, insects, or mold take hold of a building, it causes real structural and financial harm. Insurance companies often cover pest-related damage, and they need a partner who can respond fast and document everything properly.
For Oleter, offering pest control alongside fire and water restoration means clients get one trusted company for multiple emergency needs. For insurance companies, it reduces complications and speeds up claims handling.
This makes Oleter a more valuable and sticky partner and creates a more stable, recurring revenue stream that doesn’t disappear when the economy slows down.
Floods, fires, infestations, and structural failures do not pause during downturns. They accelerate claims, demand rapid response, and reward scale, proximity, and operational discipline. That’s exactly what makes these services so attractive to investors like Klar.
The Insurance Connection That Makes It All Work
A defining feature of Oleter’s model is its deep integration with insurance companies. Most property damage restoration work is insurance-funded, providing predictable demand even during economic downturns.
Insurers value partners who can respond quickly, document thoroughly, and resolve claims efficiently.
The bigger and more reliable Oleter’s network becomes, the more attractive it is as a nationwide insurance partner. This is not a coincidence. It is the whole point of building scale across four countries.
What Makes This Strategy Different From Others
Many roll-up strategies fail because companies grow too fast and lose service quality. Klar and Oleter appear to have avoided this with a clear focus on three things.
Culture first. Bo Ingemarson, Oleter’s chairman, confirmed the plan involved growing both organically and through acquisitions while emphasizing a strong focus on people and culture. In service businesses, where skilled workers are hard to replace, this focus matters a great deal.
Clean integration. New acquisitions are brought into Oleter’s systems and training structures before the next deal is pursued, rather than just being added as loose financial assets.
Operational improvement. Klar’s investment philosophy emphasizes operational improvement, sustainability, and cultural alignment rather than financial engineering.
