Manchester digital transformation agency Sputnik Digital has marked its 21st anniversary by acquiring a long-standing delivery partner.

The agency, specialising in the design and development of enterprise websites and applications, has delivered projects for the likes of GoCompare, Swinton Insurance and Fluent Money.

Sputnik Digital has cemented its long-standing relationship with Citadel Secure by acquiring the Manchester digital consultancy for an undisclosed sum.

As part of the deal Citadel’s founder Jim Larking has joined Sputnik’s board and become a minority shareholder.

Sputnik’s founder and CEO Andy Nicol said it’s a deal he’s been trying to do since 2014.

“Jim has worked with us on some huge projects in recent years and has become a vital member of the team,” he said.

“It’s a real statement of our intent and we’ve got some ambitious plans moving forward and will be able to provide an even better service to our clients.

“At Sputnik Digital our strapline is ‘precision digital engineering’ and Jim understands that writing flawless code is in our DNA.”

Larking, who is Sputnik’s chief technology officer, said: “We began collaborating with Sputnik about eight years ago and have just got closer and closer. I launched Citadel Secure in 2003 but now felt like the right time to join forces.

“We’ve got a great pipeline of interesting and demanding projects with massive growth potential. Sputnik has a reputation for innovation and I’m really excited to work with Andy to take the business to the next level.”
