Where It All Started
Founded by Guido Ampollini, a seasoned expert with more than 16 years of experience in digital marketing across major brands like Google and Expedia, GA Agency was built on the idea that the global potential for digital agencies remained largely untapped.
After five years in corporate, Guido spent another five years consulting for renowned international brands, refining his expertise before establishing the agency in 2019. His vision was simple yet powerful — build an agency where a diverse team of native-speaking experts from across the globe come together to deliver personalised, data-driven strategies that drive impactful, market-specific results.
At the core of GA Agency’s success is Guido’s customer-centric philosophy, where he fosters meaningful, long-term relationships with every client by deeply understanding their core values, goals, and ambitions. This dedication sets a high standard for the team, driving them to think boldly and make unconventional decisions. Whether responding to changes in consumer behaviour or adapting to evolving global market trends, Guido’s leadership ensures the agency stays flexible, forward-thinking, and always ready to pivot when necessary.
This flexibility fosters a dynamic and supportive environment where brands — regardless of their size — can thrive. The results speak for themselves, reflected in our case studies and worldwide recognition, showcasing the lasting impact of our strategies on the global stage.
What Makes Us Stand Out
At GA Agency, we implement a holistic approach to digital marketing, optimising all touchpoints of the customer journey and maximising website performance.
Omnichannel Digital Marketing
From SEO services — including international SEO, local SEO, and technical SEO — to off-page strategies like link building and digital PR, we focus on delivering comprehensive, tailored solutions. Our expertise also spans paid media with paid social, paid search, Amazon marketing, and programmatic, all supported by data-driven insights to refine and optimise performance.
One of our standout strengths is the seamless integration of SEO & SEM synergies, ensuring that our organic and paid efforts are strategically aligned to maximise impact while optimising resources.
In-House Language Coverage & Cross-Sector Expertise
What truly sets us apart is our in-house language coverage — a key differentiator in the digital marketing space. Instead of relying on external translators, our team of 60+ native-speaking experts ensures every campaign resonates locally, while still maintaining a consistent global strategy. This localised approach, combined with centralised project management, gives us the ability to deliver results at scale, without losing sight of the individual needs of each market.
This distinctive setup has allowed us to become a strong player in the industry, delivering exceptional results in 26+ countries for clients across diverse sectors, including luxury, fashion, travel, technology, and finance.
Top Talent & Unique Team Structure
Our team structure is equally unique. We combine a mix of senior and junior talent, ensuring that every level of the team is equipped to deliver top-tier service. The management team draws from prestigious agencies like Croud and McCann, while our specialists come from renowned firms such as Jelly Fish and Performics.
We also pride ourselves on attracting top talent from leading universities, including Bocconi, Oxford University, and Rotterdam Business School. This blend of experienced leadership and fresh talent ensures that we stay ahead of trends and continue delivering high-impact solutions.
Extension of Your Team
Despite our rapid growth, we maintain a focus on a tailored approach for each client. We work as an extension of our clients’ teams, offering unmatched expertise and a personalised touch. Many of our clients belong to large, multinational groups, and over time, we’ve built lasting relationships, becoming a trusted partner to help them navigate the complexities of digital marketing.
Entering a New Chapter
A defining moment in 2024 was our integration into Celeste.

With five comprehensive units — Filoblu, Diana Corp., dAgency, The Brandformance Society, and now GA Agency — pooling their diverse backgrounds and expertise, the group leverages a powerful portfolio of services to support every aspect of a brand’s digital journey, from digital consulting, e-commerce management and development, glocal marketing, and customer experience to web design, content production, social media & communications.
Each agency maintains its in-depth vertical specialisation while working synergistically to complement one another, making Celeste the go-to destination for brands’ digital success.
With approximately 300 employees and 200 brand clients, Celeste is poised for continued acceleration as it ushers in a new and remarkable chapter in the online world.
Now, together with Celeste Commerce Hub, we aim to expand our capabilities and offer our partners an even broader ecosystem of services. This allows us to provide localised solutions while keeping everything organised under one roof.
