Case Study: Genspark scales its AI voice agent globally with Twilio Voice

Genspark scales ‘Call for Me’ AI agent globally with Twilio Voice

Genspark, a fast-growing AI platform, needed a reliable communications foundation to scale its “Call for Me” agent globally, handle telephony and compliance complexity, and let users delegate real-world tasks like making phone calls on their behalf. To support this expansion, Genspark turned to Twilio Voice.

Using Twilio Programmable Voice, Genspark enabled its AI to place domestic and international calls, conduct multilingual real-time conversations, and manage bookings and other tasks across 40+ countries. With Twilio, Genspark achieved 99.97% uptime, sub-300-millisecond latency, and a 94.3% call success rate, while growing Call for Me usage to more than 800 calls per day and driving 3.2x higher retention among users of the feature.
