Voiceflow vs Synthflow vs Retell AI

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.

Synthflow AI is a no-code platform that empowers businesses to create and deploy sophisticated AI-powered voice assistants to automate phone calls. These assistants can handle both inbound and outbound calls, engaging in human-like conversations to perform a variety of tasks, thereby enhancing customer service and operational efficiency.

Synthflow AI offers extensive integration capabilities with popular CRM systems such as HubSpot and Freshworks, as well as other applications through tools like Zapier and Make.com. This allows for seamless data flow and workflow automation.

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.
