Avenso GmbH was founded in 1999 and offers the market-leading platform for photographic wall art: LUMAS. With its LUMAS brand, Avenso GmbH democratizes the global art market through hand-signed works by over 250 renowned artists and promising talents.

The limited-edition artworks from LUMAS are produced exclusively by WhiteWall, the co-photo lab of Avenso GmbH.

Pictures and art are at the heart of both brands’ constant efforts to evoke emotions and exceed the expectations of their international clientele.

Our History

The founders of LUMAS, Stefanie Harig and Marc Alexander Ullrich, are enthusiastic art collectors. With LUMAS, these experienced entrepreneurs turned that passion into a profession.

Their goal was to make high-quality art affordable for a wider audience of art enthusiasts including new collectors. “Traditional galleries tend to offer large-format, one-off pieces or limited editions of three to five prints. Understandably, this makes the prices high, more targeted towards experienced collectors, institutions, and museums. For those looking for affordable yet authentic art, there is a big gap in the market. LUMAS was created to close that gap and create a new space for art that speaks to all art enthusiasts.”

After the first LUMAS gallery opened at Berlin’s famous Hackescher Markt in 2004, many locations followed. These days, LUMAS now has over 30 galleries around the world in cities like New York, Paris, London, and more.
