About Retell AI
Retell AI is using first-principles thinking to reimagine the call center with cutting-edge voice AI. Thousands of companies now use Retell's AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we've scaled to $80M in ARR with a team of 50, up from $5M at the start of 2025, and are now valued at over $1.5B.
Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI. Instead of basic automation that needs constant human tuning, we're creating intelligent AI “workers” that act as frontline agents, QA analysts, and managers, continuously executing, monitoring, and improving every customer interaction.
We're growing fast and looking for ambitious builders who want to tackle hard technical problems, move quickly, and have a real impact on one of the fastest-growing voice AI companies in the world.
Let's build the future together.
About founders initiatives
Founders Initiatives is a cross-functional team that works directly with Retell's founders on the company's highest-priority opportunities and challenges. Team members are expected to operate across functions, build from first principles, and help scale the business in whatever way creates the most impact.
This is not a narrowly scoped role, it is a high-ownership builder position where you will work across product, engineering, GTM, operations, and AI systems to design and ship core company infrastructure.
