There are billions of calls made every day which will soon be handled by AI. Today 70% of business customer support calls are outsourced to call centers and contact centers. These call centers are looking for a solution that they can build simulate, and deploy voice agents all in one platform. We are building this.
Through YC we grew at 22% week over week and went through demo day with the some of the top revenue in the batch. We already work with the largest contact centers in the world and are looking for people that want to build the future of AI phone support together.
Every day, billions of phone calls are made to businesses. AI will soon power the majority of them. Businesses need a way to build, simulate, integrate, and deploy voice AI agents—we are building this.
To create AI voice agents that can truly match human performance, we need 99.999% reliability. We’ve achieved this by building fine-tuned LLMs, real-time monitoring, Zapier-like automation, and robust infrastructure that can scale instantly.
We are scaling quickly—our company grew 22% week over week in YC, finishing in the top 5% of companies by revenue in our batch, closed a seed round, and haven’t stopped growing. We are now looking for a Forward Deployed Engineer to join us in San Francisco (or willing to relocate) and help our customers scale to millions of calls.
