Our Sectors
Business Services
Calera has a long history of successfully building leading business services organizations that share a number of common characteristics. Our partners operate highly defensible businesses, often with a strong focus on end-markets where clients value domain expertise and specialization. They provide services that are mission critical to their clients, though not their client’s core competency. As a result, they have enduring client relationships that tend to expand in scope over time.
These businesses have a strong opportunity to leverage their unique models to drive significant growth and profitability. At the same time, our prospective partners often face a number of hurdles in taking their business to the next level. These include opportunities to ramp sales and marketing efforts, professionalize process workflows, invest in technology infrastructure, broaden service offerings, expand geographically, and consolidate fragmented industries.
Calera has helped its partners address these challenges and others with a deep bench of operating talent. We engage each of our partners in a collaborative strategic dialog to develop a plan that is custom fit for their business. Through this approach, our partners have been able to successfully elevate their businesses by building upon the foundation of what has made them unique and successful.
