AI agents automating B2B software implementation

What is your company going to make? Please describe your product and what it does or will do.

We build AI agents that learn any B2B product within 20 minutes and automate customer implementation tasks. Teams like technical customer success and sales engineering use our agents via Slack, text, or email to handle onboarding, product administration, health audits, and custom integrations. Our agents pull context from existing tools to execute complex workflows without needing human intervention.

Where do you live now, and where would the company be based after YC?

We live and work in San Francisco, CA, and the company will remain based here after YC to keep close to customers and the AI ecosystem.

Explain your decision regarding location.

San Francisco is where we can best reach our early users and AI talent. Staying local makes recruiting and customer development easier.
