- Framework agreement underpins phased deployment across Liberty Global operating companies
- AI-powered customer interactions will create simpler, faster and more effective customer journeys allowing care teams to focus on more complex tasks
DENVER and LONDON, Sept. 23, 2026 (GLOBE NEWSWIRE) --
Liberty Global today announced a three-year strategic partnership with Sierra, a conversational AI platform that is redefining how businesses interact with their customers, to support the rollout of its technology across Liberty Global operating companies. Liberty Global is accelerating the use of AI across its businesses to make customer interactions easier, more intuitive and more effective.
The framework partnership agreement provides Liberty Global’s businesses with a common approach to deploy AI agents capable of engaging customers in natural language, across chat, voice and text.
By enabling AI agents to handle routine and increasingly complex interactions, the partnership will also allow customer-care teams to focus more of their time on situations requiring human judgement and deep expertise.
Liberty Global will deploy Sierra across its approximately 80m fixed and mobile connections in Europe through a phased programme, with implementation already started and the use cases and channel mix tailored to the requirements of individual markets, brands and customers.
Founded by Bret Taylor, former Co-CEO of Salesforce and Chairman of OpenAI, and Clay Bavor, former Google executive, Sierra has emerged as the leading company in the customer experience AI space. The company was valued at $15bn in its latest funding round in May 2026 and its platform is already used by more than 40% of the top 50 companies in the Fortune 500 and one in three of the leading banks, powering billions of customer interactions in industries such as financial services, retail, telecommunications, healthcare and more.
Mike Fries, Liberty Global Chairman and CEO, said: "Sierra has built a game-changing platform that we are excited to deploy across our footprint. By combining Sierra’s technology and deployment expertise with the deep knowledge of our local teams, we will deliver better customer experience across our group by making customer journeys simpler, faster and more effective.”
Bret Taylor, Sierra CEO and Co-Founder, said: “We’re excited to partner with Liberty Global — a pioneer in applied AI and a telecommunications leader with significant scale, expertise and a deep understanding of European customers. This partnership is a strong vote of confidence in Sierra’s ability to improve customer experiences, reduce the burden on support teams and grow revenue. We look forward to working with Mike and the team as we roll out agents across Liberty Global’s companies.”
