Thomas H. Lee Partners Acquires Queue-it in Cross-Border SaaS Exit

Boston-based private equity heavyweight Thomas H. Lee Partners (THL) has agreed to acquire a majority stake in Queue-it, a leading developer of virtual waiting room and website traffic management software, from Nordic private equity firm GRO Capital. The transaction represents a classic cross-border secondary buyout, marking a lucrative exit for Copenhagen-based GRO, which first backed the company in 2020. While financial terms of the deal were not disclosed, the transaction highlights the persistent appetite of large-scale US private equity firms for capital-efficient European software-as-a-service (SaaS) businesses that have proven their enterprise utility.

Founded in 2010 and headquartered in Copenhagen, Denmark, Queue-it pioneered the concept of the virtual waiting room to prevent website crashes during high-demand events, such as major e-commerce drops, concert ticket releases, and public sector registrations. The company's software acts as a gatekeeper, placing excess website visitors in a first-in, first-out queue, thereby protecting transactional integrity and server health. Under GRO Capital's ownership over the past six years, Queue-it expanded its global footprint, particularly in the US and Asia-Pacific regions, serving high-profile clients like Ticketmaster, Currys, and major retail brands.

For GRO Capital, the sale represents a successful realization of its investment thesis from its 2020 entry. During its holding period, GRO focused on institutionalizing Queue-it's operations, expanding its enterprise sales motion, and diversifying its product suite beyond simple queuing into bot mitigation and abuse prevention. This exit underscores the strength of the European mid-market tech ecosystem, where regional private equity firms can nurture local startups to international scale before handoff to larger US sponsors capable of driving late-stage global consolidation.

This transaction is emblematic of a broader structural trend in the venture capital and private equity landscape: US buyout shops crossing the Atlantic to source mature tech assets. With US software valuations remaining highly competitive and often inflated, American sponsors are finding attractive risk-adjusted returns in Europe. European enterprise tech companies often trade at more reasonable multiples relative to their growth rates and cash-flow profiles compared to their Silicon Valley peers, making them prime targets for US private equity firms armed with record dry powder.

From THL’s perspective, Queue-it represents a resilient, high-margin asset with deeply embedded customer relationships and high switching costs. The acquisition fits squarely within THL's focus on automation, enterprise productivity, and digital infrastructure. By leveraging THL's deep operational resources and extensive network in the North American market, Queue-it is positioned to accelerate its enterprise penetration in the US, which already accounts for a significant portion of its revenue. The deal signals that despite macroeconomic headwinds and higher interest rates, high-quality infrastructure software remains highly liquid.

Moving forward, the transaction sets a fresh benchmark for valuations in the niche but critical web traffic management and cybersecurity sectors. Industry observers will be watching whether THL pursues an active add-on acquisition strategy to build a broader digital experience or security platform around Queue-it, a common playbook for US sponsors seeking to maximize multiple expansion. Additionally, the exit will provide GRO Capital with realized returns to support its fundraising cycles, reinforcing the viability of the European growth-equity model in a challenging liquidity environment.
