Prosero Security Group AB acquires JM Lukko- ja Turvatekniikka Oy in Finland

2023/11/29

Prosero is proud to announce the acquisition of JM Lukko- ja Turvatekniikka Oy, a well-respected family business built on professional expertise and a wide range of security services. This strategic addition will allow Prosero to continue strengthening its market presence and delivery capacity for high-quality security technology in the Birkaland and central Finland region.

JM Lukko, founded as a family-owned operation by Ari-Pekka Nurminen in 2013, has established itself as a dependable supplier of high-quality security services in the Birkaland and central Finland area. The firm offers tailor-made solutions for lock and access-control systems, door automation, alarm and surveillance systems, fire protection equipment, and electrical installations. The goal of the company is to provide integrated security solutions to cover every need, in order to be their customers’ single source when it comes to high-tech security.

JM Lukko has developed robust, long-term business relationships with customers in private and public-sector organizations, industry, construction, and housing cooperatives. The firm’s success in the market is the result of competitive strength; the company wins business by remaining attentive to customer needs and offering extensive industry competence through dedicated staff who prioritize quality service. Using a balanced service portfolio featuring a mix of projects and service agreements, JM Lukko has created a solid foundation for long-term growth.

The company’s 10 employees work from two offices: one in Jämsäin (southern central Finland) and one in Mänttäin (northern Birkaland). During 2022, turnover amounted to EUR 1.4 million.

The current CEO, Ari-Pekka Nurminen, will step down from this role, but will continue to manage daily operations together with the incoming CEO, Ville Nurminen.

“We look forward to continuing our journey, and together with Prosero, we can take on the challenges of the future,” says Ari-Pekka Nurminen, founder of JM Lukko- ja Turvatekniikka Oy. “ As we make this decision to sell our family company, we do so knowing that the new owners will appreciate and nurture the core of the business. As part of the group, we can continue our operations as we have done earlier. This will build security for our employees and our customers, too. Together, we can continue our dedication to delivering optimal solutions and the highest level of service to our customers.”

“We’re very happy that JM Lukko has chosen to become part of Prosero,” says Jyri Aho, Country Manager for Prosero Finland. The company’s expertise and strong customer relationships offer great opportunities for future synergies with our local operations in the area. With this acquisition, we look forward working with JM Lukko to develop and offer even more extensive security solutions to our customers.”
