Improve customer experience
Reduce wait times and get rid of restrictive IVR phone menus or legacy chatbots, which are incapable of offering customers the immediate support they expect. Stellar's AI agents instantly answer your support calls with an incredibly lifelike voice, and can autonomously resolve 70% of customer requests. Stellar agents go further than answering basic FAQs, and can look up or update data in your systems where needed.
Support customers 24/7
Manage an unlimited team of AI support agents, that can assist your customers 24/7. Allow customers to help themselves during evening hours and weekends, and scale up your customer support at any time to handle sudden spikes in customer support requests.
Save up to 50% on operating costs
Hiring and training a great customer service team is expensive, yet on average support employees spend more than half of their time on simple but time-consuming routine requests. Stellar lets your team focus on the 30% of support calls where personal service truly makes a difference, while we handle the remaining 70% of calls that are easy to automate. Offer better support without growing your team, and reduce operating costs by 50%.
Rely on enterprise-grade security
Stellar offers enterprise-grade security and data privacy. The Stellar platform is ISO27001 certified and GDPR compliant. Zero Data Retention and EU Data Residency contracts with our AI providers guarantee your data will never be used for training the AI models. Our platform includes a sophisticated set of safety layers to protect your systems and AI agents against common attack vectors.
Stellar's AI agents speak with a lifelike voice, and can be tailored to your brand using a range of voices and personas. Effortlessly support your customers across 50+ languages.
Stellar can look up customer-specific information and make changes on behalf of the customer during a conversation, just like your human customer service agents. No more frustrating phone menus that lead a customer nowhere. No more endless waits in queue for a basic request. No more limited opening hours.
