Perwyn Divests Interact Software to Castik Capital in 3.2x Return Deal

By USFM•December 2, 2025

Perwyn has signed an agreement to sell its stake in Interact Software to funds managed by Castik Capital, achieving a significant 3.2x return on its investment. This transaction highlights Interact's impressive growth and strong positioning in the SaaS industry, particularly in enhancing internal communication for large organizations.

In a strategic move within the private equity landscape, Perwyn, a European private equity investor, has announced its decision to exit its investment in Interact Software, a Manchester-based provider of a SaaS platform designed to enhance internal communication, knowledge sharing, and employee engagement. This exit will see Perwyn transferring its stake to funds managed by Castik Capital, a notable investment firm, which underscores the growing interest in technology-driven solutions for workplace collaboration.

Financially, the transaction is poised to realize a remarkable 3.2x multiple on the invested capital for Perwyn, reflecting the significant value growth achieved during its investment period. Notably, Interact Software has demonstrated robust performance, increasing its annual recurring revenue (ARR) and EBITDA by over 2.5 times. The company has successfully attracted a diverse portfolio of blue-chip customers across North America, Europe, the Middle East, and its primary markets in the United States and the United Kingdom.

The strategic rationale behind this deal lies in Interact's strong market position and scalable business model, which aligns well with Castik Capital’s investment strategy focused on growth-oriented technology firms. The acquisition is expected to further propel Interact's expansion and innovate its offerings, ultimately benefiting its clientele and enhancing shareholder value.

The transaction is currently subject to customary completion conditions, with the timeline for finalization yet to be disclosed. Following the completion of this deal, stakeholders, including employees and shareholders, can anticipate potential shifts in company strategy under Castik Capital's stewardship, which may lead to new growth opportunities and operational enhancements within Interact Software.

From a market perspective, this acquisition could signal increased investor confidence in the SaaS sector, particularly in solutions that improve organizational efficiency and employee engagement. Additionally, the successful transition may inspire other private equity firms to explore exits in high-growth tech firms, potentially influencing market dynamics across the industry.

As with any merger or acquisition, the transaction will require adherence to regulatory approvals, including antitrust considerations, to ensure compliance with relevant laws and regulations. With the technology sector under heightened scrutiny, both Perwyn and Castik Capital will need to navigate these regulatory waters effectively to secure a smooth transition of ownership.
