Lawyers converting discovery documents, designers sharing client assets, accountants processing financial records. Arvello is designed for the work you can't afford to compromise on.
How we build
A clear philosophy, applied to every product.
Privacy is infrastructure
Not a feature or an upsell. Every product we build starts from the assumption that your files are confidential. On-device processing is the default. Cloud is opt-in and encrypted.
Focused over broad
We ship products that do one specific thing extremely well. No feature bloat, no scope creep. A FoundryStack product earns trust by being reliable and predictable, not by trying to do everything.
Respect the professional
Our users handle client files, legal documents, and financial records daily. They deserve software that is direct and honest - no dark patterns, no surprise uploads, no data monetization.
