Oak Tree Hill Capital-backed Siloy Acquires Cyberclick to Expand Southern Europe Digital Marketing Presence

Siloy, Europe’s foremost HubSpot Elite Solutions Partner backed by Dutch private equity Oak Tree Hill Capital, has expanded its presence in Southern Europe by acquiring Cyberclick, a prominent Spanish digital marketing agency headquartered in Barcelona. The deal adds Cyberclick’s 70 specialists to Siloy’s existing workforce, bringing the group’s total to approximately 300 professionals across Europe.

Founded in 1999, Cyberclick is recognized as one of the earliest HubSpot partner agencies globally and holds Elite Solutions Partner status. The company combines over 25 years of experience with an AI-driven approach to inbound marketing, marketing automation, revenue operations (RevOps), performance marketing, and content services. Cyberclick operates from its headquarters in Barcelona with additional offices in Valencia and Madrid.

This acquisition reinforces Siloy’s strategic ambition to become a leading HubSpot partner in Europe, particularly by strengthening its position in Southern Europe. Cyberclick will maintain its brand identity and continue delivering its comprehensive 360-degree digital marketing and sales services. The integration will foster collaboration between the two teams, creating synergies that benefit clients and employees alike.

David Tomas, CEO of Cyberclick, states, “Joining Siloy allows us to preserve everything we have built while unlocking new opportunities for growth and innovation, especially in AI. Being part of a European network of customer engagement experts enhances our strength and enables us to continue helping organizations succeed with a personal, practical, and results-driven approach.”

Siloy’s CEO adds, “We are delighted to welcome David Tomas and the Cyberclick team. Their 25-plus years of expertise in inbound marketing, automation, and AI complement our vision perfectly. By combining our knowledge and experience, we can deliver greater impact to clients across Europe while keeping culture and collaboration at the core. Together, we are exploring tomorrow’s possibilities today.”

Siloy unites several HubSpot partners under one brand, including Webs, Trialta, Invise, Chili Digital, BBD Boom, ProsperoHub, Conversion Crew, Vipu, and LEVR. The group leverages AI-powered innovation to transform customer experiences and is among HubSpot’s fastest-growing partners in Europe.

The acquisition enables Siloy to cross-sell HubSpot-related marketing and sales automation services across a broader client base. It also enhances the combined service portfolio with Cyberclick’s AI-driven inbound marketing and RevOps expertise. Operational efficiencies are expected through shared technology platforms, consolidated administrative functions, and optimized resource allocation across European offices.

Market trends indicate that two-thirds of B2B buyers now prefer a vendor-free experience during initial research, often using AI tools to evaluate and shortlist solutions. Siloy’s expanded capabilities position it well to meet these evolving customer preferences.

While Cyberclick will continue operating under its own brand, further integration is planned to standardize best practices and improve client engagement through integrated service models. The deal value was not disclosed.

Looking ahead, Siloy aims to accelerate growth in Southern Europe by leveraging combined expertise and innovation in AI-driven marketing solutions. The acquisition also intensifies competition among HubSpot partners and digital marketing agencies in the region, potentially prompting further consolidation and investment in technology.

Challenges include aligning organizational cultures and managing phased integration to realize synergies without disrupting client services. However, the combined entity’s enhanced capabilities and geographic reach are expected to create significant value for clients and stakeholders.
