Belfor Holdings responds to more than 280,000 calls a year for global property restoration needs. Growth has been helped by several acquisitions in Scandinavia, Germany, France, Canada and the United States. The company's response to Hurricane Ian in late 2022 and 2023 also produced revenue growth.

Increased demand for its products, such as comfort, battery performance and cable technology-related products, have contributed to growth for the automotive supplier.
Altimetrik's growth stems from the market's adoption of its "Digital Business Methodology," a holistic framework that focuses on delivering digital business outcomes. The framework unites business, engineering and data scientists in a cloud-based ecosystem.
H.W. Kaufman Group said it has invested in talent, technology and professional development resources, which has helped fuel growth for the firm.
Atwell saw growth from land development, power and energy, and the oil and gas markets. Strategic acquisitions have also contributed to growth, which has expanded the company's services, geographies and industries.
Belle Tire has been able to grow revenue by launching and scaling new stores in new markets, optimizing sales in heritage markets, as well as strategic acquisitions, said Donald Barnes III, president.
Strengthening vehicle demand over the past three years has helped revenue bounce back from a pandemic-induced trough, especially demand for its trucks and SUVs. GM grew its market share, and higher vehicle pricing also contributed to growth.
With continued fluctuations in market conditions and ongoing changes to its core business, Kenwal pivoted to new markets and technologies to achieve additional revenues.
Sachse's multifamily and hospitality construction divisions have experienced significant growth, which includes clients such as Perennial, Crawford Hoying and Roxbury Group. The education sector has expanded into K-12, which includes Pontiac Schools. Its retail business continues its expansion across North America, catering to luxury brands such as Christian Dior, Gucci, Celine and RH (formerly Restoration Hardware), as well as electric vehicle makers Rivian and Tesla. Sachse also expanded its market presence in diverse local and national segments.
BorgWarner achieved growth organically through new products and systems solutions that evolve from in-house research and development and go into production. A series of acquisitions over the past several years has also driven additional revenue.
Revenue growth was due to expansion of project sizes and customer growth plans post-pandemic. Dearborn Mid-West was involved in a number of projects that involved converting plants from producing internal combustion engine components to electric vehicles, largely due to the industry push and incentives over the last several years for electric vehicles.
New business, product launches and performance improvements have contributed to growth for Lear. During 2023, Lear acquired I.G. Bauerhin, a Germany-based supplier of automotive seat heating, ventilation, active cooling, steering wheel heating, seat sensors and electronic control modules. The acquisition added new product technology and further expanded its suite of in-vehicle comfort technologies. In 2022, Lear announced a new plant in Independence Township to supply battery disconnect units to General Motors.
Seko's growth is primarily attributed to supply chain expansion coming out of COVID restrictions. The logistics company was responsible for shipping key consumer goods that were in high demand, including automotive parts and building materials.
Empire Realty credits bringing in builders, architects and interior designers as a contributor to its growth. It has also reduced operational costs to increase profit margins.
The Dearborn-based architecture firm has seen continued diversification in the manufacturing sector and growth driven by the transformation of the automotive industry.
