1. Greggs – Reinventing a Traditional Brand
Industry: Food & Bakery

The Transformation:
Founded in a Birmingham garage in 2012, Gymshark quickly grew into a global brand by leveraging fitness influencers on Instagram and YouTube. They targeted a niche fitness community, focusing on aesthetics and authenticity.
Instead of traditional ads, they sent free products to micro-influencers who genuinely loved the brand.

4. Monzo – Marketing with Transparency
Industry: FinTech
Strategy: Community-led growth and transparency
The Transformation:
Monzo disrupted the traditional banking model by marketing themselves as the people’s bank. They built hype by offering early access to users and created waiting lists that fostered FOMO (fear of missing out).
Their marketing was built around transparency — they openly shared product roadmaps, bugs, and even internal challenges.

- Exceptionally strong word-of-mouth growth
- One of the most trusted challenger banks in the country

They turned controversy into attention — and attention into loyalty.

- Built a cult-like following
- Valued at over £1.8 billion
