Cardinal Digital Marketing has secured the 18th position on the Atlanta Business Chronicle's 2025 Book of Lists for Largest Advertising and Marketing Agencies. The ranking is determined by the number of full-time Atlanta employees as of January 2025, showcasing the company's significant local workforce and regional impact. The Book of Lists, presented by The Business Journals, provides a comprehensive overview of influential companies that shape local economies. Their researchers employ rigorous methodologies to compile rankings using exclusive data specific to metro Atlanta businesses.
Founder and CEO Alex Membrillo expressed pride in the recognition, emphasizing the company's work with clients across metro Atlanta and nationwide. Founded in 2009, Cardinal Digital Marketing has consistently demonstrated remarkable growth, previously being ranked as the #1 fastest growing agency in the Southeast and appearing multiple times on the Inc. 5000 list of fastest-growing privately-held US companies. This trajectory underscores the agency's sustained expansion and competitive positioning within the industry.
Cardinal specializes in helping companies develop robust online presences through a comprehensive suite of digital marketing services. These services include digital strategy, search engine optimization (SEO), pay-per-click advertising, social media advertising, web design, and analytics, with a particular focus on the healthcare sector. The agency's approach distinguishes itself by prioritizing client profitability over mere traffic or impressions. By developing engagement strategies that transcend platform limitations, Cardinal aims to solve unique marketing challenges while keeping the client's customer perspective at the forefront.
The ranking matters because it reflects Cardinal's tangible contribution to the Atlanta economy through employment and specialized service provision. As a performance marketing agency concentrated on healthcare, its growth signals the increasing importance of digital expertise in a critical sector. The recognition also validates the agency's business model, which emphasizes measurable outcomes and strategic client partnerships rather than superficial metrics.
Beyond its marketing achievements, Cardinal has also been recognized as one of the Best Places to Work in Atlanta and has received the Atlanta Business Chronicle's Pacesetter Awards for seven consecutive years, underscoring its commitment to both professional excellence and workplace quality. These accolades complement the Book of Lists ranking by illustrating a holistic organizational strength that extends beyond financial or size metrics to include employee satisfaction and consistent performance. The combined recognitions suggest a resilient and well-regarded firm that contributes to the regional business ecosystem in multiple dimensions.
