About Us
We build digital services
that never see your data.
Our Vision
A world where services operate without access to or control over our data.
Our Mission
We make plaintextless services and distributed control the default.
Our Story
From research to real-world infrastructure.
Born from cryptographic research at the University of Wuppertal,
utilacy brings privacy technology into everyday infrastructure.
2022
The idea takes shape
We received the Gründungspreis+ for digital innovations from the German Federal Ministry for Economic Affairs.
2023
utilacy is founded
Supported by EXIST Transfer of Research, we developed utilacy from cryptographic research at the University of Wuppertal and founded utilacy GmbH.
2024–2025
Our technology is patented
A patent for TLShare was filed in 2024 and granted in 2025.
2025–2026
From technology to product
With BMBF StartUpSecure support, we developed InvisiCloud for real-world deployment.
Today
Bringing plaintextless infrastructure to the market
We are bringing InvisiCloud to market and extending its protection model to more digital services.
Meet the team
Cryptography. Engineering. Product.
We turn cryptographic research into practical, privacy-preserving infrastructure.

Design Principles
How we design privacy infrastructure.
Minimize Trust
We minimize trust by following two principles: the Principle of Least Plaintext and the Principle of Least Control.
- Principle of Least Plaintext
- No party should access more plaintext than necessary.
- Principle of Least Control
- No party should have more individual control than necessary.
Simplicity
We address challenges at their root cause instead of adding layers of complexity and workarounds.
Compatibility
We preserve what already works by building on existing applications, protocols, and infrastructure instead of reinventing established solutions.
