Funds managed by Castik Capital have agreed to acquire a majority stake in Interact Software from Unicorn Asset Management, Octopus Ventures, Perwyn Advisors, the former Chairman, the Executive management, and other minority shareholders. The investment is designed to accelerate Interact’s push to become the core operating system for the enterprise employee experience, with a focus on product expansion and targeted M&A.
Unicorn AIM VCT plc, the former Chairman, and executive management will retain minority stakes following the transaction. CEO Simon Dance will continue leading Interact alongside the existing executive team.
Headquartered in Manchester, Interact provides an enterprise SaaS platform used for internal communication, knowledge sharing, and employee engagement. The company serves blue-chip customers across North America, EMEA, and the Middle East, with the U.S. and U.K. as its largest markets.
The broader employee experience market continues to expand as enterprises focus on retention, culture alignment, and cross-functional communication in hybrid environments. Interact plans to capitalize on that momentum through continued investment in its core intranet platform, deeper product innovation, and expansion into adjacent employee experience categories—both organically and through M&A.
The deal remains subject to closing conditions.
Support: Interact was advised by KeyBanc Capital Markets and Clearwater (M&A), EY Parthenon (Commercial), Deloitte (Financial and Tax), Greenberg Traurig and Slater Heelis (Legal), and Crosslake (Tech). Castik’s advisors included Houlihan Lokey, William Blair, Bain, PwC, EY, Skadden Arps, and White & Case.
