Why do we exist and what do we do?
addmustard is an award-winning brand, marketing and technology agency for entrepreneurs. We add the strategic and creative fire-power of an advertising agency, to the precision and incision of a digital marketing agency, to grow the value of our clients' businesses.
We are a team of 35 brilliant brand, marketing and technology experts: a core in-house team based in the United Kingdom: Soho, London and Brighton, Sussex. Supported by a network of specialists from around the world.
How do we add value to our clients?
addmustard has worked with over 50 founders since 2013. We've created spectacular investment success stories and exits. Our roots are the in-house marketing team of a VC-backed start-up that grew to £350m in four years.
We're hired directly by investors to help grow the value of their investments.
We've:
- Increased the value of a telecoms to cybersecurity business from £240m to £795m
- Turned a £10.1m loss into a £4.3m operating profit for a luxury retailer
- Enabled a 27x exit multiple for an online travel business
- Added £19.5m of brand value through an integrated campaign for an estate agent
Who exactly are we looking for?
Our brand and culture are bold, precise, energetic and irreverent. You will need to be all four, too. And because our clients are entrepreneurial, you need to have or be keen to develop an understanding of the unique challenges of working with entrepreneurs and their businesses.
We're looking for an exceptional commercial and strategic leader to build and lead addmustard's paid media proposition.
This role is about far more than running campaigns. You'll own the direction of our paid media offering, ensuring every strategy, recommendation and pound of client investment contributes directly to increasing business value. You'll lead our Paid Media Manager and wider performance specialists, while acting as a trusted advisor to founders, CEOs, CMOs and investors.
You'll combine strategic thinking with forensic attention to detail. Comfortable discussing commercial performance, customer acquisition, lifetime value and marketing investment with senior client stakeholders one moment, before reviewing campaign structure, attribution or creative testing frameworks with the team the next.
You'll understand that paid media doesn't exist in isolation. You'll have a strong understanding of the role paid media plays within a wider digital marketing strategy, working closely with our SEO, CRO, brand, data, development and creative teams to build integrated growth programmes that drive measurable commercial outcomes.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
You're naturally curious about where advertising is heading. AI-driven advertising, automation, first-party data, measurement, creative optimisation and emerging platforms excite you - not because they're fashionable, but because they create competitive advantage for our clients.
You'll be equally passionate about developing people. Building capability, raising standards and creating an environment where the paid media team consistently produces award-worthy work.

- Lead and continually evolve addmustard’s paid media proposition, ensuring it remains commercially differentiated, innovative and focused on creating measurable business value for clients.
- Become a trusted strategic advisor to founders, CEOs, marketing leaders and investors, translating business goals, forecasts and growth ambitions into clear paid media strategies.
- Own the strategic direction and performance of paid media across the client portfolio, building a strong understanding of each client's products, audiences, commercial objectives and customer journey to ensure budgets, channel plans and optimisation priorities deliver measurable business outcomes.
- Lead, mentor and develop the paid media team, setting high standards for strategic thinking, campaign execution, communication, accountability and progression.
- Work closely with SEO, CRO, data, creative, brand, content and technology teams to deliver integrated growth strategies, ensuring paid media supports the full customer journey across both online and offline touchpoints.
- Drive the trading and performance of client products across paid media, understanding the nuances of different product types, audience behaviours and buying journeys to shape strategy, optimisation and innovation across platforms.
- Lead paid media audits, proposals, pitches and senior client presentations, identifying opportunities to win new business, grow existing accounts and strengthen addmustard’s commercial performance.
- Establish and maintain robust processes, quality standards, forecasting and reporting across all paid media delivery, ensuring strategies are translated into consistently excellent work.
- Contribute actively to addmustard’s leadership team, helping shape agency priorities, develop the wider Performance proposition and improve how teams collaborate to deliver exceptional client outcomes.
