The Role
Own Gemcult’s US D2C ecommerce revenue, P&L, unit economics, paid acquisition, Shopify conversion, CRM, retention, SEO outcomes, and live-commerce channel. Build the India-to-US live-selling operation across major social and commerce platforms, while hiring and coaching a lean growth team. The role requires hands-on performance marketing, CRO, lifecycle marketing, analytics, and experience with high-value considered purchases. It is based in Mumbai, in-office, with evening US-overlap hours and direct Founder reporting.
Summary Generated by Built In
Gemcult is a premium fine-jewelry and lab-grown-diamond (LGD) brand selling engagement rings and fine jewelry to the US market, built on independently certified (GIA / GCAL) super-precision-cut diamonds. We're launching now — and looking for one owner to drive the entire D2C ecommerce and growth engine.
Gemcult is backed by an established gem & jewelry manufacturer-exporter, combining startup ownership with the stability and supply chain of a serious operator.
This is a builder-operator role, not an agency-management seat. You'll own the revenue number and build our acquisition channels hands-on — including a first-of-its-kind India-to-US live commerce operation across Facebook Live, eBay Live, Instagram, and TikTok Shop.
Key Responsibilities
- Own the US D2C revenue number, P&L, and unit economics (CAC, LTV, ROAS, contribution margin, AOV, repeat rate)
- Drive performance marketing / paid acquisition across Meta, Google, and social; manage the SEO agency to outcomes
- Build and run the live commerce channel end-to-end — stream calendar, live merchandising, and host team — from zero
- Own Shopify site conversion (CRO) and lifecycle / CRM / retention marketing (email, SMS)
- Build and coach a lean, high-performing growth marketing team
Requirements
- 5–8 years in D2C / ecommerce growth or performance marketing, with a revenue line you've personally owned
- Hands-on across paid media + CRM + CRO — not just managing agencies or dashboards
- Strong command of CAC, LTV, ROAS, contribution margin, and payback; data-fluent (GA4, dashboards)
- Comfort selling high-AOV, considered purchases (jewelry / luxury / diamonds a plus)
- Live commerce, livestream selling, and/or US-market experience a strong plus
- Shopify ecosystem experience preferred
Essentials: Mumbai · in-office · US-overlap (evening) hours · Reports directly to the Founder
On offer: real P&L ownership, equity/ESOP, and the chance to build a greenfield live-commerce channel for a premium international brand.
