About us

An AI and social first company

We aim to make everyone feel welcome online. We combine multiple years of experience from the areas of Community Management, Trust and Safety and Machine Learning to achieve this.

Privacy and BIAS

Privacy first and mitigating bias

Machine Learning models do not need to know your name and number. We build anonymisation algorithms that remove any personal information that is used in our machine learning models.

We also actively work to remove bias from our algorithms in collaboration with our customers, using both a better understanding of the community and latest technical techniques. Watch our talk on how this is done.


Together we achieve more

We believe that only through collaboration can we achieve real change in tackling abusive behaviour online and make everyone feel welcome. We are therefore both active and certified with organisations that push both social issues and technological boundaries.
