Safety by Cilia approached Sigma Connectivity with a vision — to create a wearable safety accessory that empowers women through design and technology. Together, they have developed a discreet product that combines form, function, and purpose -designed to give women greater freedom and security in their everyday lives.

For Cissi Nilsson, founder of Safety by Cilia, it was essential to find a partner who could turn her vision into reality, a discreet yet powerful solution that feels as much like a piece of jewellery as it does a personal safety device.

“When we began working with Sigma Connectivity, the challenge was clear – there was no product that combined personal safety with a design that felt natural. I wanted to create something that not only worked technically but also looked and felt stylish. The goal was to give women a tangible tool for safety in their daily lives,” says Cissi.

Sigma Connectivity played a central role in the development of Safety by Cilia’s bracelet, from the first technical concepts to a complete, market-ready product.

“We’ve been their full R&D partner – from hardware and antenna design to software, power solutions, and integration with the app, as well as finding the right manufacturing and supply chain partners,” says Daniel Zetterlund, Sigma Connectivity Stockholm.

Although the product itself is technically simple, a single button connected via Bluetooth, the development process came with challenges. Sigma Connectivity took over the project from a previous partner and had to adapt quickly to an existing technical setup under a tight timeline.

“We inherited a technical framework and a short lead time, which required us to work very efficiently to recover lost time. It demanded close collaboration, quick decisions, and a lot of creativity,” Daniel explains.

That collaboration became a key to success. “Sigma Connectivity truly listened to our needs. They combined technical expertise with an understanding of the user’s reality, which helped us test and implement solutions quickly,” says Cissi.

The partnership between Safety by Cilia and Sigma Connectivity is built on shared values – innovation, responsibility, and a commitment to using technology to make a real difference.

“It’s been a perfect partnership on every level. Cilia’s capabilities combined with ours have resulted in a product that’s now on the market, and performing beyond expectations,” says Daniel.

For Sigma Connectivity, the project reflects both deep technical expertise and a clear purpose.

“We’re strong in wearable technology and have led several projects aimed at empowering women. Everyone wanted to be part of this – not just for the technical challenge, but because this product genuinely helps make the world safer,” says Daniel.

The Cilia bracelet is a clear example of how design and technology can merge to create real social impact. With a discreet press of a button, both GPS positioning and audio recording are activated – features that can be crucial in an emergency.

“Sigma Connectivity’s technical expertise has been absolutely essential. By integrating the technology that enables GPS positioning and audio recording with a single press, they made my vision of increased safety a reality,” says Cissi.

The collaboration is set to continue. Work is already underway on the next generation of safety products -including a smart lipstick with new functionality and even more advanced technology.

“We view this collaboration as long-term. Sigma Connectivity is a natural partner in our upcoming projects,” Cissi concludes.
