About
Built to keep data where it belongs.
Penweir is a small, independent company from the Netherlands. We build one product: a gateway that lets companies use language models without handing over data they shouldn't.
Why Penweir
Useful AI shouldn't need your customers' data.
Most companies want to use language models for the work they already do: summarising invoices, answering support mail, enriching a CRM. Each of those workflows carries personal data to a model the company doesn't run.
The usual answers are to ban AI, or to trust a vendor's promises. Penweir is a third option: a control you run yourself, that decides field by field what may leave, and that keeps a record of every decision without keeping the data.
