Hitherstone
A small US business that does the legwork on public information and turns it into things people can use: clean datasets, short history films and puzzle books.
What we make
Public datasets
Government data, cleaned, documented and sourced, with a free sample of every set.
Coming soonHistory time-lapses
Maps and places changing over the centuries, a few minutes at a time.
Coming soonPuzzle books
Large-print sudoku and other puzzles, carefully checked to have one answer.
Coming soonHow we work
We use software, including AI tools, to gather and check the material, and a person reviews everything before it goes out. Every dataset says where its data came from and when.
