European influencer marketing leader Stellar Tech has acquired Netherlands-based creator platform Join, merging it with its own marketplace Creatorz to form what the company claims will be the most powerful creator-brand connection platform across the Benelux region.
The deal marks Stellar Tech’s third acquisition in just over a year, following the purchase of Belgian influencer analytics startup Influo in July 2024 and German SaaS platform IROIN® in March 2025. The latest move continues Stellar Tech’s aggressive consolidation of Europe’s fragmented creator marketing ecosystem by combining local expertise, data infrastructure, and AI-backed campaign management tools under a single, scalable platform.
While the financial terms of the Join transaction were not disclosed, the Belgian technology firm positioned the acquisition as strategic, emphasizing the combined platform’s ability to serve a broader spectrum of micro-influencers, user-generated content (UGC) creators, and brand clients across both Belgium and the Netherlands.
What makes this acquisition significant for the Benelux creator economy and why now?
At the heart of the acquisition is scale — both in terms of market coverage and technological depth. Join, a well-known Dutch platform with thousands of vetted creators and brand partners, brings AI-powered discovery and matchmaking capabilities to the table. The company has built a reputation around simplifying how brands work with influencers across campaign types — from paid content to gifting collaborations — and automating the workflow behind these relationships.
By integrating Join with Creatorz, Stellar Tech aims to offer brands a single point of access to a large, curated pool of creators across the Benelux region. According to institutional observers familiar with the creator economy’s growth curve, platforms that bridge micro and nano-influencers with brand marketing dollars — especially those that can manage multiple collaboration formats in a compliant and data-rich environment — are increasingly seen as valuable infrastructure plays rather than mere intermediaries.
The European influencer marketing ecosystem, which has long been fragmented across geographies and content niches, is undergoing a transformation driven by AI analytics, automation, and regulatory clarity. In that context, analysts expect regional platforms to consolidate further, with a focus on seamless campaign orchestration and attribution.
How does the combined platform aim to redefine creator-brand collaboration in the Benelux region?
With the merger of Join and Creatorz, Stellar Tech said it now oversees a network spanning tens of thousands of creators in Belgium and the Netherlands. The platform is expected to support a broad spectrum of campaigns — from micro-influencer programs and short-form video content to gifting activations and branded UGC campaigns.
In a statement, Stellar Tech’s CEO and co-founder Cathy Pill emphasized that the merger is not just about geographical scale but about uniting complementary strengths. Join brings AI technology, a Dutch creator base, and a highly regarded product design team. Creatorz, in contrast, has built strong market penetration in Belgium and a growing roster of brand relationships.
Pill added that the future of influence marketing is shifting toward accessibility, agility, and automation. By blending Join’s discovery algorithms and user experience innovations with Creatorz’s marketplace traction, the new entity will be positioned to set benchmarks in campaign speed, diversity of collaborations, and data fidelity.
What is Stellar Tech’s broader platform strategy across analytics and marketplace offerings?
Stellar Tech operates on a dual-pillar platform model: analytics and marketplace.
On the analytics front, the company previously acquired IROIN®, which is now being integrated with Stellar’s in-house tools to form a unified solution for campaign tracking, influencer performance analysis, and ROI measurement. This analytics engine supports not only discovery and matchmaking but also provides brands with real-time metrics to inform creator selection, campaign optimization, and budget allocation.
On the marketplace side, Creatorz — now bolstered by Join’s capabilities — functions as the operational core for executing influencer and UGC collaborations. The integration enables brands to launch instant campaigns with vetted creators, supported by dynamic pricing, content rights automation, and performance forecasting.
Stellar Tech’s ambition is to offer both sides of the market — creators and brands — a frictionless interface for collaboration underpinned by robust data compliance and AI-powered tools. As of September 2025, the Belgian technology firm is already positioning itself as the leading full-stack platform for influence management in the Benelux.
Who is leading the newly merged platform and what expertise are they bringing?
As part of the deal, Join’s founding team will take on executive roles within the Creatorz unit of Stellar Tech. Paolo Martorino, previously CEO and co-founder of Join, has been appointed Managing Director of Creatorz. Edwin Knip, who served as Join’s CTO, is now the Tech and Product Lead of the marketplace division.
Martorino said the goal of founding Join was to make creator-brand collaborations simple, fast, and rewarding — and that by joining forces with Creatorz, this mission can now be expanded to a broader community of users and use cases. He further suggested that the definition of the creator economy itself is evolving beyond traditional influencers to include video-first creators, subject-matter experts, and even consumers generating UGC at scale.
Knip, who has a background in product architecture and marketplace dynamics, is expected to spearhead the technical integration between Join and Creatorz, with a focus on automation, creator validation processes, and campaign lifecycle tools.
Stellar Tech emphasized that the combined leadership team brings not only technical and commercial expertise, but also deep community relationships across both Dutch and Belgian creator networks — something the company believes will be critical to driving platform loyalty and long-term stickiness.
How are analysts and institutional stakeholders viewing Stellar Tech’s European expansion?
Though privately held, Stellar Tech has garnered increasing visibility in European marketing and SaaS circles due to its targeted acquisitions and emphasis on scalable tech infrastructure. Industry observers say the company’s focus on merging niche-market leaders under one cohesive umbrella allows it to compete with larger, U.S.-based influencer marketing platforms that often lack regional nuance.
Analysts tracking the European marketing tech sector note that the pace of consolidation in creator infrastructure has accelerated since 2023, as advertisers demand better compliance, faster ROI tracking, and integrated campaign management tools. By integrating vertical-specific tools like IROIN® with influencer networks like Join, Stellar Tech is seen as constructing a differentiated stack.
With the acquisition of Join, the firm now covers creator analytics, campaign execution, content rights management, and marketplace matching — all while maintaining a regional focus. This positions Stellar Tech as one of the few European players with full-stack capabilities for mid-market and enterprise clients looking to scale creator engagement programs across borders.
What is the future outlook for Stellar Tech in the European influencer tech space?
Looking ahead, Stellar Tech appears poised to expand further into adjacent markets. The company has not ruled out future acquisitions and is reportedly exploring strategic partnerships with creator networks in France and Germany. Its emphasis on micro and UGC creators also aligns with changing brand preferences in 2025, as advertisers shift away from mega-influencers toward more authentic, niche communities.
Cathy Pill noted that the merger with Join was not just an expansion of headcount or platform reach but a signal of intent: to define what influence means in the next phase of digital collaboration. From campaign diversity to cross-border scalability, the integration of analytics and marketplace tools will likely remain Stellar Tech’s competitive edge as it eyes pan-European leadership.
For now, the newly formed Creatorz–Join marketplace stands as a benchmark in regional platform consolidation — one that could inspire similar moves in the Nordics, DACH, or even CEE regions in the coming quarters.
