Service Offering
"Creative leaders are brilliant at what they do — but too often they lack the commercial confidence and language to prove it. We help them close that gap: building the skills to grow client business, lift margins and take their rightful seat at the table."
Commercial Creativity Coaching
One-to-one and group coaching for creative leaders — building commercial confidence, fluency in business language, and the practical skills to demonstrate creative value to boards, clients and CFOs. Tailored for ECDs, CCOs, heads of in-house and senior creative directors.
Commercial Training for Creative Teams
In-person and online training modules for agency and in-house creative teams — covering pricing, margins, budget management and client growth. Co-developed with the Inside Out Community and mapped to the IPA's Commercial Essentials Certificate, which Rhona and Janet co-authored.
Closing the Creative Value Gap
Strategic consultancy helping agencies and brands articulate and monetise the commercial value of creativity — addressing the systemic underinvestment in the creative layer relative to media spend, and equipping leaders to make the case internally and externally.
Agency Growth Strategy & In-Housing Advisory
Drawing on the IPA's Shift Happens report — co-authored by Rhona and Janet — this programme helps agencies navigate the rise of in-house creative and reposition themselves as integrated growth partners rather than suppliers of marketing services.
About Rhona Glazebrook
Rhona Glazebrook is co-founder of J&R Collective, a commercial creativity consultancy launched in 2025 alongside Janet Markwick to address one of the creative industry's most persistent blind spots: the gap between creative brilliance and commercial confidence. Together, they bring over 60 years of experience across leading agencies, production companies and global brands.
Rhona spent 30+ years in the creative industries — including senior roles at Grey — where she observed first-hand that commercial training for creatives, account managers and strategists was too often absent or inadequate. She is a firm believer in the power of creativity to transform brands, and has led campaigns that have won at Cannes, D&AD, IPA Effectiveness Awards, Euro Effies and APG.
Rhona and Janet are both Commercial Consultants to the IPA, co-authoring the IPA's Commercial Essentials Certificate, its advanced New Business course, and the landmark 2023 Shift Happens report on in-housing. J&R Collective works with creative leaders across agencies, production companies, in-house studios and brands — offering a free one-hour discovery conversation to anyone facing commercial growth challenges.
