Our story
Callin.io was conceived in July 2023 when our founder posed the question, “What if we create an AI specifically for phone conversations, startig from the power of ChatGPT?”
Recognizing the constraints of the current intent-matching AI systems, he aimed to develop an AI capable of posing open-ended questions and extracting insights from human interactions.
Now, our platform empowers businesses to revolutionize their communication with customers through proactive engagement strategies. In just the past five months, we have facilitated over 9 million minutes of AI-human conversational exchanges.
