Sine Qua Non: the essential ingredient

Building reputations, enhancing relationships and driving revenue

About Us

Brands and companies wanting to be the best in their field come to us. We help brands engage with their audiences whoever they are – their customers, their employees or the media. By adopting the right language and tone of voice, we start a conversation that ignites a reaction. A meaningful reaction that fires their emotions – an emotional connection, that drives behaviours and results. 

We have specific expertise in technology, sport, automotive and industrial. Founded at the turn of the millennium, we can do old school and new school. Classic corporate or millennial mindset. We’ve grown with the digital revolution.

Our clients have said of us:

“On time, on brief and on budget. A refreshing change in today’s cluttered agency environment”

“The SQN team have played a crucial part in delivering a broad media relations programme encompassing traditional print, online and social media. SQN have provided the expected gold standard in terms of client confidentiality and 24-7 responsiveness”

Our Approach

Coming from a B2B corporate background, we understand and have first-hand experience of what it’s like to be the client. And we put you first – always! We use a combination of PR, content, social media, creative design and on-site experiences to reach, engage and influence. The power of a sponsorship platform, the fusion of two perfectly suited brands, often amplifies our work and your results.
