What UK Clients Say About Our Roblox Work
Verified feedback from UK brands, indie studios, and entertainment companies we have worked with.
Fulminous shipped our Roblox pet simulator in 14 weeks at the quoted GBP cost. The Devex strategy paid off — recovered our investment within 7 months. The 100% IP ownership clause and 7-day refund window made the decision easy. Best Roblox studio we have worked with in the UK.
Sarah L.
Founder, London Indie Game Studio
Our UK fashion brand needed a Roblox activation that did not feel like a Roblox cliche. Fulminous designed a custom branded world that integrated our real fashion drops. Result: 14M visits, 28-minute average dwell time, and measurable brand lift among Gen Z. Worth every penny.
James T.
Marketing Director, UK Fashion Retailer
I was nervous about hiring a Roblox studio because of horror stories about offshore agencies disappearing mid-project. Fulminous was the opposite — UK-based team, weekly check-ins, transparent GBP invoicing. They delivered our Obby on time and on budget. Highly recommended.
