Client Rating

Real Founders. Real Shipped Work.

Selected feedback from clients in United States — reviewed, referenceable, and used with permission.

“Worked with three US agencies before Zusta. None shipped. Zusta did — production-grade, W-9 compliant, and with eastern-timezone overlap every day. Our Stripe integration is rock solid.”

“Our AI-powered support bot handles 61% of Tier-1 tickets now. Zusta built the entire RAG pipeline with Anthropic Claude and the eval harness that lets us catch regressions before rollout.”

“Engineering quality at US-agency level, at US-freelancer pricing. The architecture doc they delivered before coding started paid for itself three times over.”
