Privacy-First Software
& Consulting Services

We build privacy-first software that keeps your data under your control, and provide expert .NET consulting and modernization for enterprise teams.

Privacy-first product interfaces across desktop, tablet and mobile

Private-by-Design Software

We are actively investing in privacy infrastructure — software that keeps sensitive information encrypted and controlled by its owner, even while it is shared, synchronized, or conditionally accessed. Rather than relying on traditional "trust us" cloud models, we design systems where security is enforced by architecture and cryptography.
