Retell AI vs Voiceflow

Founded in 2023, Retell AI is built by a tight-knit team of founders with rich backgrounds at Google, Meta, TikTok, ByteDance, and more. We launched publicly in early 2022, were accepted into Y Combinator in November 2023, and raised $4.6M in seed funding in May 2024 to propel innovation further.

Retell AI's mission is to transform how businesses connect with customers—creating AI voice agents that break communication barriers and create smoother, more responsive experiences.

Voiceflow is a leading conversational AI platform designed to empower product teams in building, deploying, and scaling impactful AI agents across a wide range of use cases. Founded in 2019, Voiceflow emerged from a need to simplify the complex process of building AI agents, which had previously been limited by either overly simplistic tools or rigid legacy platforms.

Our mission is to provide a flexible, collaborative, and extensible platform that enables teams to build AI agents that are as powerful and intuitive as websites or mobile apps. Voiceflow’s mission is to empower ambitious teams to build the world’s best AI agents.
