Effortless data.

Optimize your team's workflow with cloud memoization,
experiment tracking and effortless data versioning.


A powerfully simple system for your data.

HitSave’s core mechanic is simple: memoized functions. Think @lru_cache, but persistent and anywhere.

Simple. Collaborative. Data.


You write functions; we don't make any other assumptions.

HitSave is perfect for any field: machine learning, statistics, bioinformatics, finance, vision, optimisation, business analytics... anything involving data.


Share memoized results with your team.

Collaborate and modify code without fear of consuming stale data or overwriting key results. Model weights, datasets, logs are instantly available to downstream projects.


Fuss-free dataset catalogues.

Snaphot and upload your datasets, managed in a content-addressed cloud store. Keep track of licencing, compliance and auditing. Stream public datasets directly from our catalogue.
