The deal is part of Upland Software's strategy to enhance its existing commitment to developing customer engagement solutions.
The Gowling WLG team was led by Davey Brennan and included Sue Johnston, Stephen Bowman, Samantha Holland, Nicola Caton and Tom Rank.
Commenting on Gowling WLG's role in the sale to Upland Software, Kenny Bain (CEO) of Rant & Rave, said: "Gowling WLG has been a fantastic legal advisory partner. The firm's corporate expertise proved invaluable in delivering this transaction for the company's shareholders within very challenging timescales. The effort and commitment put in by the team led by Davey Brennan went above and beyond the call of duty - all done with a smile and good sense of humour."
Davey Brennan, corporate partner and Co-Chair of Tech at Gowling WLG, added: "With a 300-strong global tech group, cross-border tech deals are very much what we do. However, an incredibly challenging timetable meant that everyone had to pull together to get this deal over the line, a task that was helped tremendously by Rant & Rave's talented management team."
"We wish the enlarged group all the very best as they work to close the gap in efficiencies around customer feedback."
