The story behind Syrenis & Cassie
Cassie is a consent and preference management platform that empowers complex, global businesses to deliver compliant and transparent communications.
Cassie’s parent company, Syrenis, was founded in 2000 and has been delivering data software solutions for more than two decades.

The rebrand
Syrenis underwent a strategic brand transformation in 2022, rebranding itself as “Cassie the product”. In the ever-evolving landscape of data and communication technologies, this change aligns with our commitment to better serve our customers and address market dynamics.
Syrenis was often recognized as a holding company for various technologies and platforms, causing some confusion among customers and in the market. As a result, we realized that having Syrenis as our primary identity created a barrier to effectively conveying our consent and preference offerings and purpose.
In contrast, “Cassie” presents a fresh and straightforward brand approach and was already significantly more recognized in the market. Cassie embodies a single-minded proposition, representing our commitment to providing solutions for centralized compliance, with powerful real-time capabilities and a future-proof approach.
The results
Cassie symbolizes our readiness to adapt to changing market needs and represents the future opportunities for our business. By rebranding as Cassie, we are clearly positioning ourselves to meet the evolving demands of our customers and the market, ensuring that we are at the forefront of innovation and progress.
The branding change from Syrenis to Cassie reflects our commitment to respecting customer preferences, building trust, and increasing customer loyalty. It also aligns with our belief that businesses should always strive to be the best version of themselves while respecting customer data.
