Real-time AI translator for sales and marketing

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

We build a real-time AI translator that supports over 20 languages for global sales, marketing, and support meetings.

Customers use it in Zoom and in person to avoid language barriers in complex discussions.

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

We don't have a fixed location currently. After YC, we'd be based wherever the company grows best, likely where we find the strongest market and talent.

Explain your decision regarding location.

We're remote for now to stay flexible and tap into wherever our customers and talent are. Post-YC, location will depend on company needs and growth opportunities.
