Celebrating 10 Years and the Launch of Avella
On Thursday 1st May 2025, we had an unforgettable evening at The Groucho Club, marking 10 years of trusted client partnerships and the official launch of our new name and brand identity: Avella. Thank you to all those who have been part of our story so far!
Adding to the energy of the day, our co-founder and partner Daryl Flack made not one, but two appearances on both the BBC News channel and BBC News at Ten, offering expert insight into recent cyber attacks on UK retailers. It was a timely reminder of the importance of the work we do - and how far we’ve come.
