No more waiting times, annoying choice menus or pushing customers through painful and restrictive chatbot flows. Our AI agents communicate naturally with a lifelike voice, speak multiple languages, and can take action in external systems just like your human agents.
Offer your customers 24/7 availability
Manage an unlimited team of AI agents, which can operate 24/7 and are well-trained from day one. Scale up your customer service at any time, and effortlessly handle unexpected peaks in customer request.
Save up to 50% on operating costs
Hiring and training great customer service staff is expensive, yet employees often end up spending most of their time on simple, time-consuming routine requests. With Stellar your team can focus on the 30% of cases where personal service truly makes a difference, while Stellar handles the routine 70%. Deliver better service with fewer people and achieve substantial cost savings from day one.
Enjoy enterprise-grade security & data privacy
Stellar provides enterprise-grade security, data privacy and compliance, including GDPR and ISO27001 compliance (certification ongoing, expected Q4 2025). Zero Data Retention and EU Data Residency contracts with our AI providers guarantee your data will never be used to train the AI models. Besides comprehensive monitoring and audit trails, Stellar's platform includes a set of built-in safety mechanisms to protect AI agents and your systems against common attack vectors.
Stellar's AI agents speak with a lifelike voice, and can be tailored to your brand preference using a range of voices, personas, and available languages.
Stellar can look up customer-specific information and make changes on behalf of the customer, all while interacting via a natural conversation. Just like customers would expect from your human customer service agents. No more frustrating phone menus with restricted pre-set options. No more wait times. No more limited opening hours.
