Refurbished iPhones, at India scale.

We build and operate the platform behind ControlZ — now one of India's largest refurbished-smartphone marketplaces, serving 5–10M daily shoppers.

ControlZ rebuilt the way India buys refurbished iPhones — quality-graded, warrantied, and shipped pan-India. Velura Labs is the engineering partner behind the consumer storefront, the backend that powers the catalog, and the operational tooling that keeps the listings honest at scale.

⌖ The brief

What they asked for.

Stand up a refurbished-iPhone marketplace that can compete with mainline OEM channels on trust and speed — and survive the consumer traffic that comes with category-leading SEO and paid acquisition. Web, mobile, and backend, all wired into the catalog, fulfilment, and warranty operations.

▣ How we approached it

The approach.

01

Headless storefront

Next.js + edge-cached storefront with SSR for product detail pages, structured data on every listing, and Lighthouse-grade performance across mobile-first traffic.

02

Catalog + grading backend

Product-grade taxonomy (A / A+ / unboxed), per-unit serial-tracked inventory, dynamic pricing on cohort + supply, returns + warranty workflow.

03

Consumer trust surface

Trust pages, warranty journeys, and structured-data SEO so refurbished doesn't equate to risky in the buyer's mind.

04

Operational tooling

Internal tools for the QC team — grading capture, photo workflows, exception queues — and dashboards for ops, finance, and CX.

◇ What we shipped
