Our story.

Founded nearly a decade ago, ‘Tonic’ evolved into newly established ‘Tonic&Co’ with directors Toni Sealey and Mariam Aslam-Digger joining forces to disrupt the traditional agency model and provide a more collaborative, straight talking and value-driven way to do business.  

The newly evolved Tonic&Co was founded on the principles of connection and collaboration – the importance and value of ‘the company you keep’. It’s what makes the world go round and what drives well-connected cohesive marketing strategies and ultimately bottom line.

With decades of experience spanning in-house and agency roles across marketing, events, brand, and strategy for prestigious blue-chip companies, luxury brands, automotive dealer groups and an enviable little black book of contacts, Tonic&Co are a marketing powerhouse to be reckoned with. 

Meet the team.

What we do is as important as how we do it and our company values drive everything we do. A diverse workforce in both background, skills and life experience adds value in so many ways. We proudly champion flexible working enabling us to tap into the widest possible talent pool of wonderful people. 

We bring together the most talented marketing and creative professionals in the business, covering more disciplines, offering more senior level experience and reaching further than many larger agencies.

Tonic&Co punches well above its weight, providing big agency thinking with a small agency price tag, producing meaningful customer experiences and driving sales. 

  • toni

    Founder & CEO

    Big picture dreamer – rebellious – foodie

    When Tonic, was just Toni.
    A tenacious entrepreneur and champion of women, Toni founded Tonic after over a decade luxuriating client side, working with some of the world’s biggest premium and luxury brands on strategy, experiential, product launches, branding and resourcing.

    Tonic was founded from a frustration with traditional agency values and a belief that straight talking, no-nonsense marketing with the right people in the right doses was the future.

    Since then Toni and the Collective have grown into a truly unique, full-service agency, attracting some of the best brands, biggest brains (and nicest people) in the industry. Leading clients such as H.R. Owen, Legal & General Homes, Ferrari, Bentley, Aston Martin and Bugatti, Toni is a big picture thinker and visionary, not afraid to challenge the status quo.

  • mariam

    Managing Director

    fuelled by connection – driven by detail – should have been a footballer

    We didn’t realise we needed a Mariam, until we met Mariam. Now we believe every business should have a mandatory Mariam, because she is an absolute powerhouse, and frankly, she’s just getting going. 

    Mariam is an innovative and dynamic trailblazer with a passion for transforming businesses, focusing on ROI driven marketing strategies that have a real impact on bottom line. She brings with her over 10 years of experience, client and agency side in senior leadership roles, across automotive, retail, hospitality and property.

    At the heart of Mariam’s drive lies a deep appreciation for the human element of business. She is fuelled by meaningful connections, with a real passion for fostering collaboration through a supportive and genuine company culture. Mariam is the leader everyone remembers and the colleague every client wants on their team.

    Apart from her impressive corporate background, Mariam was recently appointed as a magistrate on the family bench, assigned to the Greater Manchester Local Justice Area. Fulfilling her ambitions to give back to the community, whilst championing diversity and inclusivity at all levels – Mariam applies these skills and passions to everything she does at Tonic, much to the appreciation of all those lucky enough to work with her.

  • annlouise

    Experiential Director

    Peacekeeper – needs a morning coffee – biker (motor, mountain and road)

    A senior marketer, expert problem solver and cool cucumber of the business, Annlouise (Al) is a marketing professional of the highest calibre. With more than two decades under her belt heading up Experiential teams Al has worked with some of the world’s biggest blue-chip brands, although she isn’t one to brag. Leading clients such as NESCAFÉ, Savill’s, Lamborghini and Maserati. It’s Al’s personal mission to generate excellent work and have fun doing it… and to set up a remote Tonic office in the Tuscan Hills powered by Aperol.

  • james

    Creative Director

    OCD – OCD – passionate family man

    Starting out in Agency life when ‘lines’ were defining everything (above, below, integrated..really! “why didn’t we have a squiggle” he’d say?) James has always been one to challenge convention. He’s spent the past 25 or so years as a through and through Agency man, with the past 12 at the helm, and as a shareholder, of ‘Energy’, an Experiential Agency based in Covent Garden. As a Classic Car lover, it’s no surprise he has delivered international events, launches, roadshows, parties and conferences for almost every car brand there is. James, for those who have worked with him, know the ‘O’ in OCD stands for ‘Oh, so I see that’s not straight’! With an extraordinary eye for detail, a passion for everything he does whether in the office or at home with his family, and a drive to make the impossible possible; James is one man you’d want at your side.

  • heather

    Account & Bookkeeping Manager

    Determined – occasionally a tad impatient – real ale enthusiast

    Heading up all thing’s numerical, heather keeps the directorship in check, reminding us not to neglect the figures.

  • rosy

    Project Coordinator

    list queen coffee enthusiast – slow but steady runner 

    Don’t mistake Rosy’s calm demeanour for that of a shrinking violet. Rosy makes things happen and she does so with buckets of determination and a big smile. 

    With a strong background in HR and recruitment, Rosy is a proactive and dedicated campaigns coordinator with experience of managing teams and motivating and supporting her peers at all levels. Terribly organised and a list aficionado, Rosy gets stuck into all project disciplines and works with the whole directorship at Tonic, only adding to her diverse and invaluable skill set. 

    Rosy loves a challenge and no matter what we throw at her, she picks it up, runs with it and sees it through to the end with grit and determination (followed by a celebratory glass of fizz).

    Most importantly though, Rosy is a true team player and an essential and integral part of the Tonic team. Anyone fortunate enough to work with Rosy, knows it too.

“They ‘get’ our business needs, they ‘get’ our brand and they always go above and beyond. Tonic are a true extension of our team.”


Our values.

We’d love to hear from you.
