Italy's Biggest Home Site Now Uses AI Agents to Answer Every Call

Immobiliare.it, Italy's biggest real estate platform, gets over 50 million visits a month and has more than 1.2 million property listings. Buyers have questions, sellers want serious buyers, and agents are stuck in the middle. To handle this, the company built AI voice agents that can talk to people naturally, day or night, in multiple languages. These agents answer questions about listings, collect contact details, and summarize each call so human agents know how interested a buyer is.

The first agent was such a success that over 70% of sellers agreed to use it. Buyers were more comfortable giving their phone number to a voice agent than typing it into a form, which led to better-quality leads. Users also rated the feature positively. The key was natural-sounding voices with local accents – if the voice sounds fake, people hang up. ElevenLabs provided those voices and the tools to build and improve the agents.

Now Immobiliare.it is expanding from one agent to a whole network of specialized 'subagents.' Each subagent handles a small task, like answering a specific question or scheduling a visit, and they work together behind the scenes so the conversation feels seamless to the user. This approach makes it easier to test, fix, and improve each part without breaking the whole system. The company says the real innovation is in how these agents coordinate – like a team of experts passing you along to the right person without you noticing.

For everyday people, this means faster answers when you're house-hunting, and for real estate agents, it means less time on the phone and more time closing deals. The system is built to be safe and reliable, with ongoing checks to make sure the agents behave as expected. As Immobiliare.it continues to grow its agent network, it's setting an example for how AI can make customer service feel more human, not less.
