SIAM Cluster

What SIAM Cluster does

SIAM Cluster is a non-profit association founded in 2023 as Spain's first cluster dedicated to Advanced Air Mobility (AAM) and Urban Air Mobility (UAM). It functions as an industry consortium, bringing together airlines, airports, eVTOL manufacturers, infrastructure operators, urban transport providers, and municipal governments to coordinate the development of the Spanish air mobility ecosystem. Its founding coalition includes EHang, Aena, Iberia, Vueling, Ferrovial, EMT Madrid, and the city councils of Madrid and Barcelona, giving it representation across the full AAM value chain.

The cluster's core activities include publishing reference documents such as the Libro Blanco on Advanced Air Mobility, running specialized working groups (notably the Mesa de Vertipuertos focused on vertiport infrastructure), and signing institutional protocols with key regulators and operators — including ENAIRE, Spain's national air navigation services provider. Its business model is membership-based, with dues from member corporates and institutions likely supplemented by public grants and project funding typical of Spanish cluster organizations. SIAM Cluster operates with a small team of approximately 5 employees and expanded its office footprint in 2024-2025 to support growing operational demands and member coordination.

Core offering

SIAM Cluster is a non-profit membership association that convenes the Spanish innovative air mobility ecosystem through collaborative services. It operates Working Groups (Grupos de Trabajo) for industry collaboration, runs the Mesa de Vertipuertos stakeholder forum on vertiport development, and publishes sector resources such as the Libro Blanco de Vertipuertos. Members include air mobility operators, manufacturers, software developers, infrastructure builders, research institutions, and public administrations.

Product overview

SIAM Cluster (Spanish Innovative Air Mobility) is a non-profit association serving as the first Spanish cluster for innovative air mobility. Rather than a traditional product company, SIAM offers a portfolio of collaborative services including Working Groups (Grupos de Trabajo) for industry collaboration, the Mesa de Vertipuertos forum for vertiport development dialogue, and the Libro Blanco de Vertipuertos white paper publication. These services facilitate networking, knowledge sharing, R&D collaboration, and industry positioning among member companies in the air mobility sector.

Products and services

• Working Groups (Grupos de Trabajo) Collaborative teams formed by SIAM members to drive projects and activities that accelerate innovation, share knowledge, and influence regulations and trends in the air mobility sector. Each working group is led by a Secretary General and Technical Coordinator and focuses on topics such as vertiports, U-space, and other sector priorities. The service is for SIAM member companies, research institutions, and public administrations in the innovative air mobility ecosystem.
• Mesa de Vertipuertos (Vertiport Forum) A working group and stakeholder forum dedicated to generating dialogue about vertiports, addressing operational and functional requirements, and fostering relationships between public administrations, regulators, operators, manufacturers, and constructors in the air mobility sector. The forum organizes working sessions and workshops covering regulatory frameworks, infrastructure design, urban planning integration, and operational aspects of vertiports.
• Libro Blanco de Vertipuertos (White Paper on Vertiports) A comprehensive white paper providing vision on vertiport development, challenges, and opportunities in innovative air mobility, with an executive summary available as a free downloadable resource. Produced through the Mesa de Vertipuertos working group for industry stakeholders, regulators, and infrastructure planners.

Scale indicators3 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• ADS Group: The UK trade association representing the aerospace, defence, and security industries, with extensive policy advocacy, events, and supply-chain programs. Like SIAM, it operates as an industry advocacy and convening body, but at a substantially larger scale and across a broader sector scope.

Direct peers

• Aerospace Valley: A French aerospace cluster bringing together companies, research centers, and educational institutions across the Occitanie and Nouvelle-Aquitaine regions. SIAM operates with the same regional-cluster, public-private membership, and collaborative R&D convening model.
• CORAC (Conseil pour la Recherche Aéronautique Civile): A French organization coordinating civil aeronautics R&D among industry and research partners, with working groups that define national research priorities. Similar to SIAM, CORAC brings together operators, manufacturers, and research institutions to advance aeronautical innovation through collaborative projects.
• Vertical Flight Society (VFS): The world's oldest and largest technical society dedicated to vertical flight, including helicopters and eVTOL aircraft, with active working groups, publications, and an annual forum. SIAM shares VFS's focus on innovative vertical-lift air mobility and uses a similar convening and technical-publication model.
• Commercial UAV Alliance: A US-based industry organization advocating for the commercial UAS industry before regulators and policymakers. SIAM mirrors this role for the Spanish UAS/eVTOL market, particularly in shaping U-space and vertiport regulatory frameworks.
• Association for Unmanned Vehicle Systems International (AUVSI): The largest global trade association for the unmanned aerial systems industry, representing manufacturers, operators, and service providers across commercial, civil, and defense markets. SIAM parallels AUVSI's role as a convening body, policy advocate, and networking hub, but for the Spanish innovative air mobility ecosystem specifically.
• Global UTM Association (GUTMA): An international non-profit promoting safe and efficient integration of unmanned aircraft into airspace, focused on U-space and UAS Traffic Management. Like SIAM, GUTMA brings together industry, regulators, and research institutions to shape UTM standards — but at global rather than Spanish scope.

Regional players

• Hamburg Aviation: A regional aerospace cluster for the Hamburg metropolitan area in northern Germany, focused on cabin technology, aviation services, and emerging air mobility. SIAM shares this regional cluster model and member-driven convening approach, but serves the Spanish market.
• HEGAN (Basque Aerospace Cluster): The aerospace cluster for the Basque Country in northern Spain, bringing together aerospace companies, research institutions, and universities. As a regional Spanish aerospace cluster, HEGAN is comparable to SIAM in cluster model and geographic proximity, though focused more broadly on traditional aerospace than innovative air mobility.
• BavAIRia: The aerospace cluster for Bavaria, Germany, with active programs in drones, UAS, and aerospace innovation. SIAM has a comparable focus on innovative air mobility and a similar cluster membership model, though it operates at national rather than regional scope.
