The Global Opportunity

1.8B

Potential users locked behind language barriers

Internet users who prefer content in their native language — and leave when it isn't.

40%

Average conversion lift after localization

Measured across 200+ product launches in non-English markets since 2021.

67

Languages currently supported

From Icelandic to Tamil, with full RTL, plural-form, and character-expansion handling.

A product built in Brooklyn should feel native in Berlin, São Paulo, and Osaka.

Localize is the translation engine that reshapes your website and app word by word, screen by screen — without touching your codebase.

02 / The Team

A global newsroom,
working in concert.

Yuki Tanaka, Lead Linguist at Localize, Tokyo, Japan
はじめまして
Cultural Nuance

Yuki Tanaka

Lead Linguist · Tokyo, Japan

"The word "privacy" translates literally into Japanese — but the cultural weight it carries is completely different. A UI that says "your data is safe" to an American audience reads as a threat in Tokyo. That nuance is what separates localization from translation."

Yuki leads linguistic quality for East Asian markets. With a background in cognitive linguistics and 11 years of software localization, she has shipped products for Sony, LINE, and three Series-B SaaS companies entering Japan.

QA Methodology

Diogo Ferreira

QA Engineer · Lisbon, Portugal

"String comparison testing will tell you if the word is there. Screenshot testing will tell you if the word fits. German strings run 40% longer than English — if you only check the string, you'll ship a broken button to 83 million people."

Diogo built Localize's context-aware screenshot QA framework from scratch. He maintains test suites across 14 active client projects and has caught over 2,300 layout regressions that string-only testing would have missed.

Sprint Planning

Sophie Tremblay

Project Manager · Montréal, Canada

"Every product team thinks they need six months to localize. We've never taken more than twelve days for a first market. The sprint works because we sequence the work the same way you sequence a product release — by user impact, not by alphabet."

Sophie manages localization sprints for e-commerce and SaaS clients across North America and Europe. She developed the 12-day sprint methodology now used across all Localize engagements, reducing average time-to-market by 68%.

03 / The Process

Twelve days.
A new market.

Sophie's sprint methodology ships your first market in 12 days. Every step is sequenced by user impact, not by alphabetical order.

Day 1–2

Content Audit & String Extraction

We crawl every screen, extract every string, and categorize by user-impact tier. Marketing copy, UI labels, error messages, and legal text each follow different translation protocols.

Yuki Tanaka + Engineering
Day 3–5

Cultural Adaptation Review

Native-speaking linguists review strings in context — not in a spreadsheet. Idioms, formality registers, and culturally loaded terms are flagged and resolved before a single string is translated.

Regional Linguist Team
Day 6–8

Translation + Glossary Lock

Parallel translation with a shared glossary ensures brand terminology stays consistent across every surface. Product names, feature labels, and legal terms are locked before review.

Translation Team
Day 9–10

Context-Aware QA Testing

Diogo's screenshot testing framework fires across every screen in the target locale. Character expansion, RTL layouts, date formats, and currency symbols are verified in-app, not in isolation.

Day 11–12

Staging Review & Handoff

A final review with your product team on the staging environment. Sophie coordinates the sign-off checklist and prepares the deployment package — including rollback strings if needed.

trial-to-paid conversion in DE

"We assumed our English UI would carry us through Western Europe. Localize showed us exactly where German users were dropping off — three screens we'd never have found without the cultural audit."

cart abandonment in PT-BR

"Abandoned carts in Brazil were costing us $40K a month. The culprit was a checkout flow that used formal Portuguese — the kind no Brazilian uses when they're buying anything. Twelve days later, that number dropped by 61%."
