This Is Why

We Should Work Together


We understand that information security is a key concern, especially in an industry as niche as artificial intelligence. That’s why we have designed a system that involves multiple layers of security checks to take place, manually and automatically.


Garbage in, garbage out. The accuracy of our results is the forefront of our work because we know how important it is to the solutions that you develop for your users and clients. We always aim to deliver highly accurate datasets with a combination of automated quality control features and a human intelligence team that is hand-picked and fully managed.

Domain knowledge

We have worked with machine learning teams who are building solutions for companies across a variety of industries.This is especially helpful in improving search relevance and discoverability of products. Our diverse community of workers have the combined experience across 50 industries, from fashion to furniture to fast moving consumer goods (FCMG).
