Onething Design vs Topflight Apps: overview

Onething Design

Headquartered in Gurugram, India with additional locations in Bangalore and San Francisco, the studio reports 52–73 employees depending on source. Onething serves a broader industry spread than most fintech-only specialists — BFSI, consumer products, enterprise, healthcare, and automotive — making industry breadth its defining trait.

Topflight Apps

The company states a team of roughly 40, though some directories list 51–200 (likely an inflated bracket, treated as approximate).
