About us

Our company
We’re a team of technologists and data scientists building specialist software to help clients collect, clean and enrich their data. Our pragmatic human-in-the-loop solution streamlines and systematises human data work, combining man and machine to deal with a wide range of data preparation challenges.
The software was initially developed in 2014 within the research and data science division of global investment manager, Winton Group, and used exclusively internally for four years. In 2018, we spun out from Winton as a team of seven and since then we have doubled in numbers, closed our first funding round jointly led by Fidelity International and Barclays, been selected to be part of the Investment Association’s inaugural fintech accelerator Velocity, won the FIA Innovator of the year award in 2019, and secured a range of clients from hedge funds and asset managers to data vendors and technology start-ups.
