We build software people trust with their most sensitive work.

FoundryStack Labs was founded with a straightforward observation: too many software tools treat privacy as a marketing checkbox rather than a design constraint. The result is software that technically "works" but quietly accumulates data, uploads files without clear notice, or locks essential features behind dark upsells.

We build differently. Every product starts from the assumption that users handle confidential files - client documents, financial records, legal materials. Privacy is baked in from the first line of code, not added as a feature after the fact.

Our first product, Arvello, was built for professionals who routinely work with sensitive files and need conversion tools they can actually trust. It is a file conversion workspace where everything runs on your device by default - no uploads, no surprises.
