Data-science products

Data-science products we build and run.

Independent web products where we own the full stack — from the data and the models to the interface our users see.

CityDataLab — one of the live Raphos data-science web products

Alongside client work, Raphos designs, builds and operates its own data-science web products. They are where we put our research into production at scale: natural-language processing, knowledge graphs, embeddings, econometric modelling and large-scale data engineering, all wrapped in fast, usable interfaces.

Each product below is live and independently accessible. They share a common DNA — taking a large, messy dataset and turning it into something genuinely useful — and they double as a public showcase of how we think about data, modelling and product design.
