At Starley, we’re developing Cotomo, a leading voice-based AI conversation platform. Our goal is to redefine how humans interact with AI.
Cotomo is designed for everyday conversations, whether it’s a casual chat or discussing something deeply personal. Instead of focusing on task-driven intelligence, we’re crafting an AI that feels like a companion—someone you can confide in and forgive when it doesn’t get everything right.
In just three months since launch, Cotomo has facilitated 100 million conversations, making it one of the world’s most popular human-AI voice platforms—entirely through word of mouth.
We’ve built much of our core technology in-house, including large language models, speech recognition, and synthesis models, to ensure a seamless and natural experience. As our user base grows, so do the technical challenges, creating a dynamic and exciting environment.
Looking ahead, we plan to expand beyond Cotomo, bringing AI to life in new ways—whether by turning beloved characters into AI companions or creating communication tools tailored for seniors.
Join us in shaping a future where the connection between humans and AI is more meaningful than ever, surpassing what’s been imagined in novels, manga, and sci-fi.
How We Work
Cotomo is a small, ambitious team operating with a high level of intensity and ownership.
Responsibilities are intentionally broad, and difficult problems are rarely confined to a single layer of the stack. In the same week, you might improve a conversational model, investigate a speech pipeline, integrate a new generative model, optimize GPU utilization, compare an external API with an in-house model, and work with Product on a new user experience.
This can be a demanding environment. It is best suited to people who enjoy high-intensity startup environments, substantial autonomy, and being personally responsible for important outcomes.
