Clay vs Onething Design: overview

Clay

Clay — clay.global, not to be confused with the unrelated AI sales-data company at clay.com — keeps an unusually low public profile for a studio whose client list includes Coinbase, Uber, SendGrid, MoneyLion, Meta, Google, Slack, Snapchat, Amazon, Toyota, and Samsung. Neither its founding year nor its team size is published or independently confirmed, which is itself worth flagging to prospective clients doing due diligence. What is clear from its portfolio is deep, repeated experience across B2B, SaaS, AI, and fintech product design, based out of San Francisco with significant NYC-based client work.

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.
