The SISS BLISS Jewelry, Berlin, Germany
be bold, take gold
Franziska von Hardenberg is a successful serial entrepreneur and one of the most recognized faces in the German startup scene. Driven by a vision to make things better, she has been building successful brands since 2012.
Over the past decade, she has founded five companies and is now focusing her efforts on the most beautiful precious metal in the world: gold. This passion manifests in two synergetic ventures: The SISS BLISS, her jewelry company that specializes in personalized fine gold jewelry crafted in German master workshops, and BLISS BANG CAPITAL. Together, these companies aim to create the world’s first closed-loop gold cycle, where customers' old gold is bought back, melted down, and recycled into new, bespoke jewelry.
For over 10 years, Franziska has independently built successful brands, relying on powerful visuals, customer-centric strategies, decisive leadership, passionate entrepreneurship, and genuine sustainability in the luxury segment. Her brands are deeply influenced by her personal passions—art, travel, interior design, fashion, and jewelry. Through Instagram, Franziska has successfully transformed a digital community into an analog movement, the #SISSTERHOOD, which is loyal, affluent, and unique. Over 50,000 people follow her daily life on social media.

"how I started the siss bliss"
"When our daughter Elsa was born in 2015, I asked my husband for a necklace engraved with her name– and couldn't find anything we liked. In the end, we had one custom-made by a goldsmith in Hamburg. Little did I know, this necklace would become quite the conversation starter—sometimes several times a day! That’s when I decided to offer these necklaces to all of you.
Every necklace still comes from that same small goldsmith, the very one that crafted my original piece. I adore jewelry, but I’m also a stickler for top-notch quality in both craftsmanship and materials. Since my pregnancies, I’ve developed a sensitivity to gold-plated brass (thank you, hormones!), so only solid gold makes the cut for me.
Finding beautiful gold jewelry at a fair price isn’t easy, though. I’ve worn my ELSA necklace day and night, in the shower, at the gym—everywhere—for nearly seven years now. In 2017, we welcomed another addition: our little HEDI, both as a daughter and as a necklace. The HEDI necklace is longer and features a delicate bezel, but it’s just as stunning, making them the perfect pair."
We don’t know many women like Franziska
What sets Franziska apart from other entrepreneurs? She speaks openly about numbers, goals, failures, and the tough journey it takes to grow. We love her energy, her straightforwardness and her taste.
That’s exactly why we approached Franzi to create her vision of a little Nimo With Love Jacket, that can be worn 365 but especially for Oktoberfest cause we know Franzi: YOU LOVE OKTOBERFEST!

Sometimes I look at the jewelry I’ve designed for the siss bliss and can’t believe it’s actually mine. So here’s a little reminder for you: Do something you love so much that you sometimes forget it’s work.
