“Rabdos” is Greek for “rod” — a nod to Napier's rods, handcrafted tools that supercharged calculation.

We create data to make frontier models useful for the world’s hardest thinking, from the chalkboard to the wet lab. We pair domain experts with frontier models to create original and verified reasoning data: hard problems, careful solutions, evals, benchmarks, and datasets that push models beyond where they fail today.

Because Rabdos was started by academics at Penn, we can bring in mathematicians, scientists, and engineers who would not normally work for a data company. They engage because the work is framed as real research: hard questions, careful reasoning, and verified answers.

The biggest scientific breakthroughs often happen where fields meet. Rabdos is building the expert reasoning data layer that helps make those breakthroughs possible.
