Daniel was Antonio's client
Antonio helped me set up the full analytics and paid acquisition foundation for my corporate retreat lodge in Switzerland.
He implemented GA4 and GTM tracking, configured conversion events, structured our Google Ads campaigns, and provided clear documentation so I could operate independently.
He combines technical expertise with strategic thinking. Communication was clear, deadlines were respected, and the work delivered real visibility into our funnel performance.
I would definitely work with him again.

Antonio led the marketing efforts for The Fortia Group, a boutique investment bank focused on eCommerce companies. It was a diverse role with many tasks and responsibilities to juggle. He did a great job and I would recommend him for a similar role.

Ric worked with Antonio on the same team
I had the privilege of co-founding Unigamer with Antonio. In his crucial role as Head of Marketing, he demonstrated exceptional leadership and innovation by developing a comprehensive marketing plan. This plan not only positioned our brand within the gaming community but also laid the groundwork for transforming our initial concept into a fully operational pre-commercial startup.

Michelle was senior to Antonio but didn’t manage him directly
Antonio was an amazing partner to cross functional teams in supporting campaign operational excellence as part of the core marketing ops and technology team. He communicated well with stakeholders on project requests and helped them understand how to incorporate our mops processes into other team’s workflows. Antonio, I cannot thank you enough for all the wonderful work you did at Momentive.ai!
