About Us

You can’t improve what you don’t measure.

Lightbulb has been founded by a team of passionate serial tech entrepreneurs who believe that emotion & attention mapping is the next frontier for remote or online interactions.

We believe that to create great user experiences online, you need to understand what your users are thinking & feeling in real time, and you cannot do that unless you observe and measure their emotional responses.
