John Ojo — Founder, Sigma Ecommerce Agency
John Ojo
Founder & Ecommerce Growth Strategist

I'm John Ojo, founder of Sigma Ecommerce Agency. For the last 7+ years, I've lived inside ecommerce, designing storefronts, building 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 store design, conversion and retention, turning browsing into checkout and first orders into repeat ones.

Today Sigma serves ecommerce founders across 10+ countries, with 74+ stores and projects worked on and $127K+ in client store revenue influenced 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.

What We Stand For

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.

Measured on outcomes

Good design is the starting point. We judge the work on orders, conversion rate and average order value.

Design with intent

Every section, image and interaction earns its place. Nothing on the page that doesn't help someone buy.

Transparent partnership

Clear scope, honest timelines and direct access to John throughout the project.
