The strategist behind stores that scale.
I'm John Ojo, founder of Sigma Ecommerce Agency. For the last 7+ years, I've lived inside ecommerce, designing storefronts, engineering funnels, running ad accounts and building the systems that turn traffic into revenue.
I founded Sigma three years ago after seeing too many beautiful stores fail to convert. My work sits at the intersection of design, conversion psychology and growth engineering, translating brand into checkout, and checkout into revenue.
Today Sigma serves ecommerce founders across 10+ countries, with 74+ stores built and $127K+ in influenced revenue to date. We're a strategic growth partner, not a template shop. Every project starts with real discovery, ends with measurable outcomes, and stays honest about what will and won't move the needle.
Our operating principles.
Strategy first
Deep discovery before design. We audit before we build so every decision is grounded in your data, margins and customer.
Revenue-obsessed
Beautiful is table stakes. Sigma engagements are measured against CVR, AOV, ROAS and contribution margin.
Design with intent
Every section, image and interaction earns its place. No fluff, no filler, just conversion.
Transparent partnership
Clear scope, honest timelines and direct access to John throughout the project.
