Product engineering
From the first sketch to a running product: web apps, APIs and the infrastructure under them. One small team owns the whole thing.
Software,
built deliberately
Deferred Labs is an independent software studio in Romania. We build and run our own products — and help a few teams ship theirs.

What we do
AI that holds up
Assistants, document extraction and Q&A built on language models — with guardrails, evaluations and cost limits, not demos.
Rules-heavy software
Tax, compliance and official formats. We turn legal text into code that can show which article every number comes from.
