Fantasy vs Onething Design: overview

Fantasy

Fantasy — originally Fantasy Interactive — has operated independently since 1999 out of studios in San Francisco and New York, which alone sets it apart from most large agencies on this list that have since been folded into a holding company. Its client history reads like a highlight reel: Nike, Disney, Microsoft, Netflix, Spotify, Ford, Google, and Samsung, with more recent work for 23andMe and Rokid. The studio has leaned increasingly into AI-native product design in recent years, positioning itself at the intersection of AI, product strategy, and human-centered design across categories from automotive to wearables.

Onething Design

What's now Onething Design was renamed from an earlier studio, Ketchup Designs Studio, in 2015, so its founding date is best treated as approximate. Headquartered in Gurugram, India, with additional offices in Bangalore and San Francisco, the studio reports 52–73 employees depending on source. Where most boutiques on this list specialize, Onething goes the other direction — BFSI, consumer products, enterprise, healthcare, and automotive all sit inside one team's portfolio.

Fantasy vs Onething Design: pros and cons

Fantasy
+ Independently owned since 1999, avoiding the holding-company consolidation that's absorbed several peers on this list
+ Client history spans Nike, Disney, Microsoft, Netflix, and Spotify — a roster on par with much larger agencies
+ Increasingly positioned around AI-native product design, not just legacy interface work

Onething Design
+ Covers five distinct industries from one team, useful for multi-vertical clients
+ US (San Francisco) and India (Gurugram, Bangalore) delivery footprint supports near round-the-clock work
+ $10K minimum engagement (per company website; independently unverifiable) is accessible relative to most studios on this list
+ A decade of operation under its current name, with roots reaching back further
- Founding year is approximate — the studio was renamed from an earlier predecessor in 2015
- Five-industry breadth trades off some vertical-specific depth against single-vertical specialists like UXDA
- Reported employee count varies by source (52–73), making capacity planning less precise
