Enterprise Communications System Administrator chez Apex Service Partners

Founded in 2019, Apex Service Partners, LLC (“Apex” or the “Company”) is the industry and nationwide leader in residential home services. Apex focuses on serving the HVAC, plumbing, and electrical needs of homeowners in over forty states across the country. Apex has grown to +100 locations with +9,000 team members and +$2 billion in annual revenue.

In this fragmented industry dominated by small and founder-owned businesses, the Company has a dual strategy of growing via high-frequency acquisitions (over 200 closed by the Company to date) and aggressive organic growth initiatives, including sophisticated marketing, differentiated talent acquisition and green-fielding new trades and locations. From the onset, the Company’s leaders have focused on building out a robust internal infrastructure to ensure scalability and better win in local markets around the country with the strongest brands and tactics. The team at “Partner Services”, the centralized support team for the Company, comprises 60+ hard-working, collegial team members who are focused on the success of operations across the country. Despite being the largest player in this incredible industry, Apex has less than 2% market share, and ~85% of the market is still fragmented. The Company recently received a new round of equity investment totaling $3.4B and recently closed a debt refinance in excess of $3.0B.
