About us

We are a born-global company. Our roots are in Silicon Valley as we were Google, Facebook AI and Deepmind researchers prior to founding Talka.

We are a team of previous researchers at Google AI, Facebook AI, Deepmind, and other AI research institutions working on conversational understanding that got together to tackle the deep problem of understanding video conversations and improving human communications where it adds a significant business value.

What is our ultimate mission and why are we doing this?

Humans are fundamentally social beings.

Talka improves human relationships by improving their communication patterns and mutual understanding. Communication is the bedrock of human relationships. In both business and personal settings.

We strive for impact and push the boundaries of what AI can do to improve that communication by focusing on the deep insights from conversational patterns . With better communication we will have fewer broken relationships both at work and on a personal level and ultimately more fulfilling lives.

Why is this hard?

93% of communication in face-to-face occurs beyond the content of the words. More than the text, it depends on the tone, inflection, body language, and a multitude of other conversational patterns beyond the content. Conversations are very nuanced and the signals are hard to detect. Existing products are only scratching the surface with their basic text and sentiment features.

Our headquarters

We’re headquartered in the San Francisco Bay area in Mountain View, California.
We also have a subsidiary and teams working in Canada, and in Portugal.
