# Companies with in-house R&D headquartered in Atlanta

Tamtam tracks 64 companies with in-house R&D headquartered in Atlanta. This list ranks the 30 largest by number of employees on LinkedIn, led by The Home Depot, The Coca-Cola Company and Chick-fil-A Corporate Support Center. Their median headcount is 9,835. Half of them were founded in 1956 or later.

The companies in Atlanta with in-house R&D are primarily large organizations, spanning diverse sectors such as retail, manufacturing, and higher education. Notable examples include The Home Depot, the world's largest specialty retailer of home improvement products, and The Coca-Cola Company, a global beverage firm. Georgia-Pacific LLC is a leading manufacturer of paper and building products, while Chick-fil-A Corporate Support Center provides extensive operational support for its restaurants. ICE connects individuals to data and technology, and NCR Atleos is a global leader in self-service banking solutions.

A significant pattern observed is the strong presence of companies founded in the mid-20th century, particularly in the 1940s, alongside much older institutions like Georgia Institute of Technology (1888) and newer ones like NCR Atleos (2023). This indicates a blend of established enterprises and more recent ventures contributing to the city's R&D landscape.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
