addmustard is an award-winning brand, marketing, and technology agency for entrepreneurs.

We add the strategic and creative firepower of an advertising agency, to the precision and incision of a digital marketing agency, to the flexibility of an in-house team.

A team of 35 brilliant marketing, data, brand, and tech experts – a core team based in Brighton and Soho, supported by a wider network of specialists from around the world.

And we are world-class at creating value in our clients’ businesses and brands.

Our brand and culture is bold, precise, energetic and irreverent. You will need to be all four, too. And because our clients are entrepreneurial, you’ll need to be eager to develop an understanding of the unique challenges of entrepreneurs and their businesses. 

Your single, exclusive focus is to make addmustard famous. Whilst we have developed an enviable track record, distinctive brand and compelling story, you’ll have to be creative, dynamic, relentless and hard working to compete with the other 10,000 agencies out there.

As far as your talents are concerned, we are looking for a rare combination of detail, analytical thinking, and creativity. Someone who can drive the planning of our own marketing, to increase awareness and desire for our unique proposition; plan, promote and measure the impact of our world-class content; and become an outstanding communicator, coordinator and negotiator.. You must have attention to detail, impossibly high standards and a pursuit of marketing excellence. Every number we produce, every word we write and every image we craft must be the very best it can be and your judgment and standards need to be at that level. 

You’ll also have heaps of initiative and be extremely organised, sporting an inquisitive mind, a curious nature and a desire to ask questions. Plus, you’ll enjoy the challenge of learning about a diverse range of businesses, markets, channels and audiences. 

• To study addmustard’s target audience’s values, beliefs, and motives, as well as how these elements impact their decision-making process. 
• Conduct in-depth, tailored research and analysis to identify and prioritise the digital platforms, events, and other channels that the target audience utilises.
• Help develop and implement strategies for reaching and engaging entrepreneurs through multiple media. 
• Coordinate and manage the creation of assets and collateral that addmustard needs to communicate our unique positioning.
• Support in the delivery of email campaigns, assisting with creation, segmentation, and performance tracking.
• Oversee updates and maintenance of the addmustard website, supporting SEO efforts through keyword research, optimisation of content, and analysing search rankings.
• Track performance metrics for campaigns using tools like Google Analytics, Mailchimp, Meta insights, and Searchmetrics.
• Manage and update our CRM, inputting, organising and monitoring lead data.

We pride ourselves in being bold, energetic, precise and irreverent. Equally, we are open, honest, innovative and hard working in everything we do for our entrepreneurial clients, our team and our network.

You’ll be surrounded and supported by a team who will embolden and challenge you to approach each and every day with those values in mind. We’ve built (and are very proud of) our completely flat and integrated organisational structure – we don’t care where the good ideas come from, as long as they can be turned into something astonishing and that delivers tangible, measurable value.

And when those ideas get made, deliver real value for our clients and win awards, we love nothing more than to celebrate them.

• In return for your commitment, creativity and incredible mind, you can expect:
  • To work across a diverse range of fascinating audiences, markets, sectors and projects, each with unique problems that we can solve.
  • To work alongside and be trained by industry experts at the forefront of brand, marketing and technology.
  • Our senior management is accessible, open, honest and transparent. This means we all care about you and your development, progression, success and happiness. And we regularly share financial, team, and client performance with the whole agency.
  • Flexible hours and a hybrid working structure—split between home, our eclectic Soho office, and Brighton’s vibrant Lanes.
  • Be part of an amazing, sociable and supportive team.
  • An (over)active social life: regular lunches, dinners, ad-hoc team events and now and then, holidays. 
  • Unlimited holiday allowance.
