We are a boutique agency that drives the digital growth of mid-sized and large companies.
We are Semmántica hiberus digital growth, an agency specialised in accelerating the digital growth of mid-sized and large companies.
We offer five solutions: AI visibility, paid media strategy, international growth, measurement and attribution, and SEO positioning.
We combine Paid Media to drive profitable acquisition, in both e-commerce and lead generation, SEO/GEO to increase visibility, and digital analytics to measure, make sure your results are reliable and make business decisions.
We make brands and organisations grow using Google, Meta, TikTok and ChatGPT, among others, both inside and outside Spain.
We have two proprietary methods: Sherlook, to ensure brand visibility in LLMs, and Moneyball, to optimise the profitability of an ecommerce catalogue.
We work with the care of a boutique agency and the backing of hiberus, the technology group we have been part of since 2012.
What a few students started is now a team of more than 60 professionals.
In 2008, Natalia Sampériz and Jesús Barón were studying the Master's in Electronic Business Administration at the University of Zaragoza. Together with Luis Erdociain, now Digital Analytics Tech Lead at Semmántica, and another classmate, they decided to enter an international student competition organised by Google. The challenge was clear: manage a real AdWords campaign. Our team won across Spain and was one of the best in all of Europe.
That experience awakened more than their interest in digital marketing. They started managing campaigns for their first client, Central de Reservas, and in 2011 decided to found Semmántica.
Jesús, a restless entrepreneur, stayed until 2021, when he decided to focus on a second business venture. Natalia remains at the helm as CEO.
“For me the most important thing is people, which is why taking care of my team and serving our clients with a vocation for service are my priorities as director of Semmántica”
Natalia and Jesús tell how it all began in "5 questions to Semmántica", Zaragoza Chamber of Commerce, 2017.
Meet our team
Just 20 km from Zaragoza, in 2007, Cristóbal López set out on his own with Cestalia, a maker of Christmas hampers. Self-taught and resourceful, he soon realised that a good online shop was not enough: customers had to be able to find it. In just two years he became one of the SEO references in Spain. In 2011 he joined hiberus, where he drove the creation of hiberus Search and went from entrepreneur to chief operating officer, without ever losing his feet on the ground or the perspective of someone who knows what it means to risk their own business.
Today, together with Natalia Sampériz, he leads Semmántica hiberus digital growth. Two profiles with their own strengths and a shared vision that turns their differences into synergies.
We are a boutique agency where every client is unique. We combine that closeness with the strength of hiberus, one of the country's leading technology consultancies, of which we have been part since 2012. We share an office with its UX, e-commerce and platform specialist teams, just a few metres away. When a project needs other capabilities from the digital ecosystem, we add the right talent without bureaucracy or subcontracting.
hiberus Search was born in 2013, the SEO and GEO unit of hiberus. After years of working together, in 2026 we saw the next step clearly: bringing hiberus Search and Semmántica together into a single Digital Growth team.
