For Marketing leaders
Turn compliance into growth with trusted personalization
You shouldn’t have to choose between compliance and campaign performance. Syrenis helps you deliver trusted personalization at scale, turning privacy from a blocker into your brand advantage.
Trusted personalization at scale
Syrenis is built for modern marketing teams who want agility, visibility, and customer trust. It integrates seamlessly with your existing stack, powering data-driven, privacy-first marketing at enterprise scale.
Ask once, honor everywhere
Cross-domain consent means customers only see one banner across all your brands, regions, and devices – fewer interruptions, higher engagement, consistent data.
Follow-me consent
Respect choices across devices, apps, and channels. Cassie keeps consent in sync everywhere your customers go.
Identity Service
Restore up to 35% of lost attribution caused by privacy browsers. Cassie replaces third-party cookies with compliant, first-party identifiers so you can measure true ROI.
Progressive Profiling
Build richer profiles gradually, based on engagement and trust. Collect what matters most without overwhelming customers.
Preference centre and service portal
Give customers full control of how they hear from you — reducing unsubscribes while empowering your service teams to act instantly.
Proven in enterprise environments
Cassie already powers privacy-first personalization for leading global brands:
- A food delivery platform unified consent across merchants, couriers, and customers — reducing banner fatigue by 40% and improving opt-in rates.
- A healthcare provider centralized patient preferences across digital and offline channels — building trust and ensuring compliant communication.
- A multinational financial services company restored 30% of previously hidden attribution after switching from a legacy CMP.
If Cassie can handle millions of daily interactions across regulated industries, it can handle your marketing funnel.
