Zetako – Lossless Data Compression Is Nothing Short Of A Digital Revolution

Silicon Luxembourg spoke to veteran entrepreneur Claus Rosenberg about what makes this Luxembourg company so special.

Claus Rosenberg has been building businesses since he was a teenager. He admits that he’s had some “spectacular failures” but also award-winning successes.

“My colleagues and co-founders Marc and Jonas are behind the technical aspects. There are two schools of compression of data – one is lossy compression, which you have in mp3, jpg etc. It means that the integrity of the data set has been compromised. So not the same amount of data that goes in will come out,” the entrepreneur explains.

“We take out the notes we can’t hear in our ears, or the pixels we don’t really need and so on“, Rosenberg says, explaining that in lossy compression sometimes only 99 percent will come out.

Lossless compression, where the integrity is completely intact and nothing is lost, is used in emails, and MRI scans, for instance. Larger companies will base their lossless compression system on an algorithm that was written in 1976, written by Israelis. “There has not really been any innovation there, except the speed of compression and decompression,” says Rosenberg.

In order to properly “unpack” the data this software can be heavy, some up to a gigabyte in size, and they require computer power. What is more, you can only decompress the data once everything has been shipped. “This is where the industry is now, and it’s quite large to operate in certain industries, even inapplicable,” says Claus.

“There is no need to add a layer for encryption. The core technology is 100 percent developed […]”

So what did Zetako do about it?

Marc-Antoine Augugliaro, the firm’s French co-founder, who has spent years researching mathematical theory, was able to create software that treats data purely mathematically. The software compresses data bit by bit – when one bit comes in they start compressing the data stream – and unpacking is the same, a mirroring process, just with a reversed algorithm.

Among the benefits is speed. “We run much faster, to run it on the GPU, not on the CPU, and this will be revolutionary. In a GPU you can do as many parallel calculations as you want. Because our software is extremely small it means it can sit and operate anywhere. Compression can function anywhere, because it doesn’t build the libraries that need a lot of compute power”, Rosenberg explains, adding: “The possibilities are infinite. There is no need to add a layer for encryption. The core technology is 100 percent developed, but we are still working on more layers of the tech.”

Zetako has been accepted to NVIDIA Inception programme and is working with their engineers to install its software into their arm processor. “There is so much more potential,” the CEO says.
When it comes to the business model, Rosenberg says that they are still figuring that out.

“We were approached by the maritime industry based in Holland, and we ended up working for Euronav. For them we are building a new remote desktop protocol, including our lossless system, and we have great expectations. That’s an industry that found us,” Rosenberg concludes.
