Belkoura

A quiet argument that your secrets should stay yours

Most technology companies treat your personal data as fuel. Zouhair Belkoura built a company on the opposite bet: that people would pay to keep their own content out of the machine.

That bet is called Keepsafe, and it started with something small and personal - a place to keep photos that nobody else could reach. Belkoura and co-founder Philipp Berner launched it in 2012 in San Francisco. What began as a single "photo vault" app has since grown into a family of privacy products used by tens of millions of people, spanning private browsing, a VPN, and a phone-number app for people who would rather not hand out their real one.

Belkoura did not arrive at privacy from the usual startup on-ramp. His training is in electrical engineering. He earned a PhD at the Technische Universitat Berlin, where he studied signal processing and worked on video coding algorithms - research that reportedly cut the computation needed to compress video on mobile devices by around 90%. Before that he studied telecommunications in Paris. On paper, he looked destined for a research lab or a chipmaker, not a consumer app about keeping photos private.

The pivot came through building. Before Keepsafe he founded an online retail company, Enamora, and grew it to several million dollars in revenue in roughly a year and a half before exiting. He spent time as Director of Products at Kii, and, earlier, did a stint at McKinsey. Each step nudged him closer to a realization that would define his next decade: the interesting engineering problem in consumer software isn't always the algorithm. Often it's whether people trust what you built.

Two kinds of privacy, and only one that people feel

Belkoura's most repeated contribution to how we talk about privacy is a simple split. There is data privacy, which is abstract - metadata, IP addresses, the exhaust that every device leaves behind. And there is content privacy, which is concrete - the photos, the messages, the files that people actually see, share, and care about. His argument is that most privacy conversations obsess over the first while people worry about the second.

He often reaches for a physical metaphor to explain the gap. In the physical world you close a drawer, shut a door, or flip a lid, and the thing inside is private. That instinct is thousands of years old and requires no manual. In the digital world there is no lid to close, and privacy is buried under settings menus and forty-page policies nobody reads. Keepsafe, in Belkoura's framing, is an attempt to give people back that simple, physical sense of control.

It also shapes how he talks about the harder edges of the subject. When waves of celebrity photo hacks made headlines, Belkoura was blunt that the reflex to ask why a victim took the photos in the first place is the wrong question. The failure, in his telling, is a digital world engineered so that keeping something private is the difficult part.

A CEO who still ships

For someone running a company, Belkoura stays unusually close to the product. He has contributed code and image-processing work at Keepsafe, and he writes much of the company's public thinking on privacy himself - blog posts on data-sharing risks, privacy predictions, and product launches carry his byline rather than a ghostwriter's.

That hands-on streak extends to how Keepsafe hires. Belkoura has written openly that hiring is broken, and the company reworked its process around the belief that a resume tells you little. Engineering interviews happen over video in a shared coding environment, and candidates effectively "test drive" the job - working on real problems before committing to a major life change. It is the same instinct that runs through the products: don't ask people to trust a promise, let them see how the thing actually behaves.

The result is a company whose values and product are hard to separate. Keepsafe only works as a business if it never betrays the content people store in it. The privacy promise isn't marketing bolted onto the top - it's the mechanism that makes the whole thing function.
