Their goal is to empower businesses of all sizes to operate more efficiently and enhance customer experience.
Curious Thing’s customer base spans from a single person organization to enterprises with thousands of employees. While seeking to serve businesses of all sizes, Curious Thing realized that small business groups were not only underserved, but often are the most in need of automated solutions. Their flagship product, Lucy, an AI phone answering agent, was designed to automate customer communications for small businesses. However, to achieve global reach and handle high call volumes effectively, they needed a robust communication infrastructure.

Seamless Integration with Vonage
Han Xu, Co-founder and CTO of Curious Thing said, “To meet these demands, we integrated Vonage’s flexible and scalable Communications APIs into our platform. Lucy answers calls 24/7, takes messages, and provides real-time summaries via email or text. By providing seamless access to virtual numbers, Vonage enables us to instantly launch new Lucy instances on-demand, ready to connect to the global telephony network and serve our customers effectively.”
“We launched Lucy to democratize voice AI technology to empower small businesses with seamless, human-like interactions and streamline customer service experiences over the phone,” continued Dr. Xu. “Lucy can take customer calls on behalf of the business 24x7, taking messages and sending a call summary to the business user via email or text in real-time. It can be configured with advanced options such as small call transfer and FAQ handling and appointment setting, which basically turns Lucy into an AI virtual receptionist. This integration provides extensive global network coverage, allowing Lucy to manage customer calls seamlessly across time zones. Vonage’s well-documented APIs enabled a smooth implementation, accelerating our deployment timeline.”
Empowering Businesses with Reliable Communication
The collaboration resulted in rapid growth for Curious Thing. Lucy onboarded over 5,000 customers within the first three months post-launch, handling up to 8,000 calls daily. Example success stories include an Australian accounting firm that captured critical appointment requests after hours, significantly enhancing operational efficiency, and In the U.S, a managed services provider that relied on Lucy to manage calls during the owner's surgery, ensuring uninterrupted service and peace of mind.
"Integrating Vonage’s APIs was a game-changer for Curious Thing, allowing Lucy to provide unparalleled support to businesses worldwide," said Dr. Xu. “Vonage APIs are well-documented and developer friendly, which accelerated our implementation timeline. Vonage's support, level of adaptability, and reputation as a leading CPaaS provider made them an obvious choice. As we continue to expand Lucy’s capabilities, the flexibility of the Vonage platform opens up many possibilities for future product development, allowing us to scale our solutions and meet the evolving needs of our clients.”
By leveraging Vonage Communications APIs, Curious Thing successfully addressed the communication challenges faced by small businesses, delivering consistent and reliable AI-driven customer interactions.
