What Lingo.dev does

Lingo.dev is a localization engineering platform where teams create localization engines - stateful translation APIs configured with glossaries, brand voice rules, per-locale model preferences, and quality scoring. Each engine persists domain context across every request via retrieval augmented localization (RAL). Integrate via API, CLI, CI/CD, or other integrations. Localization infrastructure behind 200M+ translated words for teams including Mistral, Solana, SoSafe, and Cal.com.

The Localization Engineering Platform

What is your company going to make? Please describe your product and what it does or will do.

We built a platform where engineering and product teams create stateful translation APIs called localization engines. These engines maintain context across translations using retrieval augmented localization, applying glossaries, brand voice rules, and locale-specific preferences. Teams integrate via API, CLI, or CI/CD to handle complex translations at scale, supporting over 200 million translated words for companies like Mistral and Solana.

Where do you live now, and where would the company be based after YC?

We live in San Francisco and have remote team members. After YC, the company will remain headquartered in San Francisco with distributed employees.

Explain your decision regarding location.

San Francisco is where we live and where our technical team collaborates best. Being here lets us access top engineering talent and stay plugged into startup and AI infrastructure ecosystems we rely on.

Is this the real Lingo.dev YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Lingo.dev's public data (launch notes, founder backgrounds, product description). It shows how a company like Lingo.dev would present itself to YC, not the text they submitted.
