Bizum launches a generative AI assistant for customer support on its website and WhatsApp

The problem
Bizum is the Spanish mobile payments service that works through the country's banks. Its customer support relied on pre-programmed answers. Customers still wrote in by email with questions about incidents, general queries and possible scams. Bizum wanted support that was more efficient, more up to date and available on more than one channel.
What they built
Bizum put a virtual assistant based on generative AI on its website and on WhatsApp Business. Generative AI is software that writes answers in natural language. The assistant works alongside Bizum's staff and is available 24 hours a day, every day. It answers questions about incidents, general queries and possible scams.
How they did it
Telefonica, through its Telefonica Tech unit, developed the assistant on its own generative AI platform. The design uses several assistants coordinated together, each handling a specific type of question, and draws on documentation provided by Bizum as its knowledge source. Telefonica also built a connection (an API) that looks up bank contact details, so questions that reach Bizum but belong to a bank can be redirected. For payment incidents, the assistant can give the user the right bank's details and even send an email on the user's behalf. Telefonica says it completed the project within three months.
Results
Telefonica reports that Bizum reached 90% accuracy in the assistant's answers and cut email contact requests by 30%. These are the vendor's own figures and the release does not explain how they were measured.
Lessons for your project
Ground the assistant in your own documentation. Bizum feeds it material it supplies, which keeps answers consistent with official guidance.
Split the work between several narrow assistants. Bizum uses several, each focused on a topic such as incidents, general questions or scams.
Route what is not yours to the right owner. The assistant looks up the contact details of the relevant bank and passes payment issues on.
Track both answer quality and ticket volume. Bizum reports accuracy and a drop in email requests, which show quality and workload effects.
Caveats
