London, UK, 9th September 2025 – Global creator-first social agency, Billion Dollar Boy, has been recognised in the prestigious IPA Effectiveness Accreditation for 2025-27 – becoming the first and only creator marketing agency to achieve Accreditation.
Widely considered the industry’s most challenging Accreditation to achieve, only 56 agencies have been recognised for the award by The Institute of Practitioners in Advertising since the biennial programme’s inception in 2021.
Accreditation is awarded to agencies that “demonstrate their commitment to business effectiveness and deliver commercial outcomes for clients, setting an industry benchmark.”
The recognition is not only an unprecedented achievement for Billion Dollar Boy but also an important milestone for the creator economy. With 72% of marketers agreeing that measurement is their number one challenge when it comes to creator marketing, the Accreditation demonstrates that the channel can deliver accountable, measurable business results. And, with new Billion Dollar Boy research showing creator ad spend growing to in excess of $1M (£765K) annually for 71% of US marketers and 52% of UK marketers, the urgency to prove effectiveness has never been greater.
Chaired this year by Alessandra Bellini, former Chief Customer Officer at Tesco, the judging panel and programme seek to celebrate agencies that make effectiveness central to their business culture. Candidates must prove that effectiveness is structurally integrated into the agency across five pivotal criteria: Focus, People, Process, Data, Tools & Measurement, and Impact.
Simon Harwood, Billion Dollar Boy’s Global Effectiveness Director, was appointed in June 2023 to spearhead the development of the agency’s effectiveness capabilities across the marketing funnel.
Built over 11 years, Billion Dollar Boy’s measurement stack includes a proprietary creator advertising platform, Companion – winner of the ‘Best Influencer Marketing Platform or Technology’ at the Global Influencer Marketing Awards 2025. From campaign outputs and share of voice to outcome-focused metrics across brand and direct sales effects, it tracks full-funnel performance in one centralised platform. Supported by AI-powered tools and dedicated measurement partners Billion Dollar Boy’s full-funnel measurement stack continues to evolve to meet marketers’ needs with creative testing and brand lift analysis linking emotional impact to commercial outcomes.
Billion Dollar Boy has delivered creator marketing effectiveness across a variety of objectives and verticals, including:
- A 14-point percentage uplift in purchase intent from the ‘New and Trending’ influencer programme for Argos, achieving a revenue ROI of £5.07, the highest of any channel.
- A 4.9% uplift in incremental sales for Old Mout Cider, far exceeding their average media contribution benchmark of 2% and achieving an ROI 44% higher.
- Increasing brand preference for Just Eat by 13 points, using insights from creative testing to beat benchmarks for both positive emotions and creative effectiveness.
Simon Harwood, Global Effectiveness Director of Billion Dollar Boy, says: “Achieving the IPA Effectiveness Accreditation shows that creator marketing can meet the highest standards in advertising with the right models, processes, and culture to back it up.
“As an agency committed to sharing industry lessons on how influencer marketing can be deployed more effectively, we are relentless in our ambition to set a new benchmark in both proving and improving the work.
“This Accreditation demonstrates that the incredible creative work we’re producing delivers commercially against both brand and business goals and, more broadly, helps to cement creator marketing as a mature and integral channel within the wider marketing mix. We’re proud to be leading that shift, and even prouder of the team who made it possible.”
Alessandra Bellini, Chair of Judges for the IPA Effectiveness Accreditation, says: “IPA Effectiveness Accreditation is a remarkable and incredibly important achievement for agencies. The Accreditation clearly demonstrates that effectiveness and delivering commercial outcomes, underpinned by great creativity for clients, is embedded into everything.”
