Clay vs Onething Design: overview

Clay

Clay (clay.global) operates out of San Francisco with substantial NYC client history. No founding year is published, so it's tagged here as unconfirmed; team size is likewise not independently verifiable — best treated as boutique-to-mid-size. Its roster — Coinbase, Uber, SendGrid, MoneyLion, Meta, Google, Slack, Snapchat, Amazon, Toyota, Samsung — reflects deep B2B, SaaS, AI, and fintech experience. This is the design firm at clay.global, distinct from the unrelated AI sales-data company also named Clay (clay.com).

Onething Design

Onething Design took its current name in 2015, renamed from a 2014 predecessor ('Ketchup Designs Studio'), so the founding year is treated as approximate. Headquartered in Gurugram, India with additional locations in Bangalore and San Francisco, the firm reports 52–73 employees depending on source. What sets it apart is industry breadth: BFSI, consumer products, enterprise, healthcare, and automotive, all served from one team rather than a single-vertical specialty.
