What do you need help with?

The real problem

Growth doesn’t break
at traffic.
It breaks inside
your funnel.

Most brands already have traffic. Revenue is lost in:

  • Product pages that don’t convert
  • Checkout flows with friction
  • Lifecycle systems that don’t retain customers

We fix the parts of your ecommerce funnel that directly impact revenue.

When brands
come to
Birubi

Three moments that bring brands to Birubi — and one outcome that defines every engagement: revenue that performs better.

Birubi — “View of the Southern Cross” · Gathang, Worimi Country

01
Migration

A platform decision is also a revenue decision.

Done right, it improves performance for years. Done poorly, it introduces friction that compounds over time.

We migrate brands from Magento, EC-CUBE, BigCommerce and bespoke platforms — without revenue disruption or data loss.

Plan your migration
02
Optimisation

Already trading — but not at your ceiling.

Conversion rates below benchmark. Checkout abandonment too high. Retention not driving repeat purchase.

This is where the fastest gains are made.

Improve performance
03
Launch

Build it right from day one.

We work with brands building for scale — not rebuilding 12 months later when the platform can’t keep up.

What We Improve

Focused on the parts of your funnel
that drive revenue

01
Product Page Conversion

Turn more visitors into buyers

Product structure, messaging clarity, content and proof.

Most product pages underperform because they’re built around features, not decisions. We restructure the hierarchy, sharpen the offer, and add the proof that moves buyers from browsing to purchasing.

Improve product page performance
02
Conversion & CRO

Turn more visitors into buyers — measurably

Product pages, UX, A/B testing, checkout optimisation.

Most stores are leaving significant revenue on the table through friction, poor page design, and checkout drop-off. We identify exactly where you’re losing buyers and fix it — with a structured testing programme tied directly to revenue outcomes.

Results in 8–12 weeks
03
Lifecycle & Retention

Drive repeat purchases and grow lifetime value

Email, subscriptions, lifecycle marketing.

Acquiring a new customer costs far more than retaining one. We build the flows, automations, and subscription architecture that move customers from first purchase to loyal buyers — reducing churn and compounding revenue over time.

Retention-first systems
04
Platform & Infrastructure

Build a foundation that supports growth

Platform migrations, architecture and setup, multi-market structure.

A poorly built platform creates drag on every other investment — ads, content, conversion. We migrate and architect ecommerce platforms so your infrastructure accelerates revenue rather than limiting it.

Who This Is For

Built for brands serious about
ecommerce growth

01
Marketing Managers & CMOs

You’re responsible for growth — but performance isn’t where it should be. You need a partner who thinks commercially, not just technically.

02
CEOs of Ecommerce Brands

You’ve found product-market fit — now your funnel needs to scale with your ambition.

03
Brands Expanding Globally

You need consistent performance across markets — including Japan. Multi-market ecommerce requires a partner who understands both the technical and commercial complexity.

Typically ¥100M+ in ecommerce revenue — or scaling toward it.

Common Questions

Common questions

What size brands do you work with?+
¥100M+ in ecommerce revenue, or scaling toward it. We work across three situations: platform migration, conversion and retention optimisation, and new brand launches built for serious scale.
Can you help if we’re already on a platform?+
Yes — most of our work focuses on improving conversion and retention for brands already on Shopify or Shopify Plus. Being on the platform is the starting point, not the finish line.
How quickly do results happen?+
Typically within 8–12 weeks for conversion improvements. Platform migrations follow agreed timelines. Lifecycle and retention systems compound over 3–6 months.
What does the Growth Audit include?+
A structured review of where revenue is being lost and how to fix it — covering your platform setup, conversion performance, checkout experience, and lifecycle systems. Available to qualified brands on an application basis.
Do you work with Japanese and English-language brands?+
Both. We are based in Japan and work in Japanese and English — with Japanese brands expanding internationally and international brands entering the Japanese market.

The Name

“Birubi” — View of the Southern Cross.

Ecommerce brands don’t fail from lack of effort — they fail from lack of direction.

We help you see where revenue is being lost and define a clear path to growth.

Just as navigators once used the Southern Cross to orient themselves, we provide that same reference point.

“Birubi” is the Gathang word for the Southern Cross — the constellation used for centuries to navigate the southern hemisphere.
