A place I had imagined differently.
Behind the scenes of “The Lion’s Den”
In 2015 I dreamed of one day sitting in the lion's den.
Ten years later, I'm actually sitting there – in Ralf Dümmel's seat , during my own pitch.
Life writes its own scripts – not always as planned, but often exactly as they should be. 🌿

The Chrambl® – invented for the washing machine, made for the whole household.
Natural. Clean. A different approach.
The Chrambl® cube was specifically designed for the washing machine's dispenser drawer – unlike pods or wash strips that come into direct contact with the clothes.
This has crucial advantages:
Avoid direct contact of highly concentrated substances with textiles or skin.
Slow, controlled dissolution over several wash cycles.
Only 4.5 g of active ingredient per wash, instead of approx. 50 g of powder or liquid detergent.
Rinsing the drawer multiple times ensures that the solution is distributed evenly, without residue or clumping.
This results in a natural, skin-friendly, and economical cleaning process that protects your machine, clothes, and the environment. And the best part: one cube can do more. It replaces not only detergent and fabric softener, but also glass, ceramic, oven, all-purpose, bathroom, kitchen, and car cleaners – always properly diluted.
1 cube = 5 washes = 0 plastic. Multiple uses instead of just one.
Independently reviewed, tested, and patented.
