Marine is part of the core team at Intlayer, an open-source project based in France that’s rethinking how SaaS teams handle internationalization (i18n).
Designed for React and Next.js applications, Intlayer removes common headaches like flickers, messy configs, and SSR hydration issues—and is evolving into a full content management solution for global teams.
What problem does your product solve, and who is it for?
Intlayer fixes the messy developer experience around i18n, especially in SSR SaaS apps.
It’s for:
- Developers who want a clean, dev-first i18n setup without flickers or complex configs.
- SaaS startups planning for global users from day one.
- Teams who need to hand off translations to non-devs (with a CMS coming soon).
Why Intlayer matters right now
- Only 26% of internet users are native English speakers - meaning 74% prefer another language.(w3.org)
- 76% of consumers are more likely to purchase if product information is in their own language.(CSA Research)
- For developers, i18n retrofits can add 20-30% extra workload if not planned from the start.(locize.com)
What inspired you to start this? What’s your personal backstory?
I joined Intlayer after seeing how often i18n is treated as an afterthought in startups, leading to ugly retrofits, SSR flickers, and bottlenecks where non-devs can’t update content.
When I found Intlayer, it solved all of those problems at once: clean setup, SSR-safe by default, and a plan to hand translation management to non-devs. That’s when I knew I wanted to help grow it.
What’s your current traction?
In our first month, we reached 100 users and grew our GitHub stars by 10x in July.
What’s one decision or moment that changed everything for your startup?
The pivot to build our own MCP (Multilingual Content Platform) server.
We realized the biggest pain wasn’t just implementing translations. It was managing them long-term. By adding a self-hosted CMS that connects directly to the codebase, non-technical teams can now edit translations without developer involvement.
It shifted Intlayer from “a better i18n setup” to a long-term content infrastructure for SaaS teams, unlocking features like A/B testing and custom workflows.
