We're defining a category as we scale across five countries, and our ambition is to reshape supply chain management for the entire hair colour industry. We're a distributed engineering team that cares deeply about building things well. We're opinionated about functional programming, and we're proud that the work we do helps small businesses thrive while cutting real environmental waste.
