US technology group J2 Global has acquired Callstream for an undisclosed sum in a deal that saw the exit of Callstream's previous backers Octopus Investments and YFM Equity Partners.
Mick Crosthwaite, CEO of Callstream, commented: "Callstream has expanded significantly following backing from YFM and Octopus Investments. They have been terrific partners and played an instrumental role in helping us achieve our success."
Grant Paul Florence, Head of the Intermediate Capital team at Octopus, added: "Callstream has developed a loyal customer base over the years and enters a new chapter of growth as part of a global enterprise."
YFM and Octopus were advised by Knight Corporate Finance. Paul Billingham, Knight Director, commented: "We have worked with Callstream since we founded Knight over seven years ago and this latest transaction is a culmination of advising on strategy, M&A and exit planning to ensure the best possible outcome for shareholders.
"M&A in the sector continues to be vibrant and we look forward to strengthening our position as an advisor in the lower to mid-market range in TMT."
