Zertifier uses technology blockchain to improve customer engagement by bridging the physical and digital worlds. It combines the power of the Internet of Things (IoT), blockchain, and smart contracts to deliver complete, immutable, and automated solutions, such as product traceability, anti-counterfeiting, document certification, secure data transfer, NFT, and tokenization.
Could you tell us how Zertifier was born and what its trajectory has been to date?
Victor Seriñana: Zertifier has a curious origin. Although we founded the company in March 2021, the story begins much earlier. Brothers Joan and Josep Jou, from Girona, had already created several technology companies. 30 years ago they founded Megatró, an IT company that has been able to continuously adapt to changes and innovations in the sector.
In 2016 we began exploring the possibilities of technology blockchain, beyond cryptocurrencies. They developed, for example, a traceability application for pork, from farm to slaughterhouse. This experience pushed them to continue researching useful applications for companies.
In 2021, both Paco and I joined the company. Paco came from the world of construction and technological innovation, and I from the corporate world. From different paths, we came together in this common project.
The beginnings were very stylish start-up: we started working in old pig farms converted into offices, and during the first year we had to work hard to get our first clients. Interestingly, these were all international: first in Canada, then Finland, Italy and Austria. It wasn't until 2022 that we started hiring staff. We are now 11 people.
Despite being in Cornellà del Terri, we have had an international vision from the beginning. And little by little we have also become integrated into local and European innovation projects, participating in clusters and initiatives such as the AEI.
What are the main services offered by the company and what technologies do you use to implement them? Could you give us specific examples of solutions you have developed in areas such as product traceability, anti-counterfeiting, document certification, secure data transfer, NFT or tokenization?
Paco Conde: At Zertifier we offer advanced digital solutions to ensure trust, traceability and security in environments where critical data is shared. The technology blockchain is our main tool, on which we develop decentralized identification systems, smart contracts and web platforms that allow us to automate processes such as verification, certification and tokenization of assets.
These technologies are applied in very diverse areas: from the traceability of physical products to the energy management of citizen energy communities. An example is ZertiDocs, which certifies digital documents with legal validity and prevents forgery. With ZertiTransfer, we allow you to send files securely and encrypted via blockchain.
With ZertiNFT, we link physical assets to their digital twin in the form of NFTs, using NFC chips or RFID technology, which is particularly useful in the cultural field. For example, we have worked with artists who wanted to offer digital proof of authenticity for their works.
A very different case is ZertiPower, a solution that facilitates the P2P exchange of renewable energy between citizens, recognized as a right by the EU. This platform integrates traceability, tokenization and autonomous organization decentralized. The Generalitat de Catalunya awarded us a public procurement innovation project to develop it.
How do you integrate blockchain technology into your solutions and what benefits does it bring to customers?
PC: Blockchain is the technological core of many of our solutions. It allows us to guarantee the integrity, transparency and security of data without the need for a trusted third party.
It is particularly useful in areas such as the certification of energy consumption, emissions or CO₂ capture — for example, by trees. This allows us to build new business models for our clients, such as monetizing the tons of CO₂ captured.
Another case is the creation of digital markets where the origin of renewable energy can be certified. But we always say: technology, on its own, has no value. It must be linked to a robust business model.

Zertifier has participated in projects such as TeraMAT 2, focused on the certification of recycled plastic materials through blockchainand inspection in the terahertz range. Could you tell us about the role you played in this initiative?
VS: TeraMAT 2 builds on the conclusions of a previous project (TeraMAT 1), which detected that terahertz technology can be useful for measuring paint residues in recycled plastic, which may have relevant industrial applications.
Our role is twofold: on the one hand, we record in blockchain the data obtained through these analyses, ensuring its immutability and reliability. This is key, especially in cases such as the system outage we experienced recently, which highlights the importance of having secure and non-manipulated data.
On the other hand, we record all the traceability of the supply chain in blockchain, from the entry of the material to its exit to the customer. This allows this information to be included in quality certificates and, in the future, linked to digital material passports.
We participate together with the MAV Cluster, the Centro Español de Plásticos, Citsalp, Das-Nano, Bestplant and Gaiker.
What other notable collaborations or projects have you done recently?
PC: We are immersed in several projects. An example is Data Spaces for Positive Energy Districts, a European project that we have just started. With the Rubí City Council as a pilot, we use the ZertiPower platform to tokenize municipal solar energy and link it to energy and mobility data spaces, guaranteeing its traceability.
We also lead ZertiCarbon, one spin-outcreated in parallel to Zertifier. With Finnish partners specialized in forest management, we digitize forests by scanning tree by tree, measuring biomass and captured CO₂. This information is incorporated into a marketplace where carbon credits can be sold, everything tokenized with blockchain to avoid fraud and duplication.
In the pig sector we started with PorkChain, from the farm to the slaughterhouse. And now, with ZertiPork, we cover the entire chain all the way to the table. We work with producers like Basatxerri, offering the consumer detailed and verifiable product information through a QR code that links to a specific website for the batch.

What motivated you to join the MAV Cluster and what benefits have you gained from this association so far? Do you believe that being part of the cluster is the best way to generate new projects and collaboration opportunities?
VS: Since 2022, shortly after founding the company, we identified that the cluster environment was very suitable for establishing collaborations and promoting innovation projects. We feel very comfortable within the MAV Cluster, which we consider very professional and close.
Organize quality activities, such as working groups, training sessions networking or assemblies where relevant issues can be debated. In the last AEI call, for example, it was one of the clusters with the most approved projects, which speaks very good for their capacity and rigor. For us, it is an ideal environment to continue collaborating and growing.
What are Zertifier's plans in terms of innovation and expansion of services?
PC: Our priority objective is to consolidate the platforms we already have in the market so that they become benchmarks in their sectors and scale them internationally. We have always had a global vocation, and this continues to be our main line.
At the same time, we work to integrate into large European ecosystems, such as Gaia-X, where we are active members. Our purpose is to help organizations and communities transform their environmental and social value through traceable, reliable and monetizable digital assets.
