Giles Peddy, who left Lewis in October, joins Missive co-founders Nicola Koronka and Emma Ross on the company board. The trio previously worked together at Hotwire.
Peddy will "lead Missive through its next chapter by championing its integrated communications services", the agency stated. Koronka and Ross become chief client officer and chief people officer, respectively.
Missive, which currently has a 19-strong workforce, was founded in 2015 by former Hotwire colleagues Koronka and Ross. The agency's client roster has included O2, Santander, PayU and Finastra. Revenue is expected to top £1.5m this year after it added six new clients during the lockdown.
Before joining Lewis, Peddy spent seven years at Hotwire, rising to deputy MD.
Ross, who was formerly head of PR and social media at O2, recently returned to Missive following a diagnosis of primary bone cancer in August 2019.
She said: “I am incredibly proud about what Missive has achieved in a few short years, despite unforeseen challenges. Missive makes a positive impact every day to the lives of its clients and staff and it has even more to offer in the future. With the addition of Giles to our talented team, our ambitions to help redefine the industry are without limit.”
Peddy said: “Having watched the growth and success of Missive, the opportunity to join Nicola and Emma to take it to the next level was too good to turn down. I am really excited to be joining an entrepreneurial and ambitious consultancy with great clients, a strong team and an outstanding culture.
“In a digital world, many agencies remain analogue. With its integrated approach to communications, Missive is primed to deliver a tangible business impact and help define the future for technology companies.”
Missive was recently named PRCA Small Consultancy of the Year 2020, and it also picked up the PRWeek UK Best Places to Work Award in the Small Consultancy category in 2019.
