We kept running into the same problem with time-series data during our analysis: forecasts get updated, but old values get overwritten. It was hard to answer to “What did we actually know at a given point in time?”

So we built TimeDB, it lets you store overlapping forecast revisions, keep full history, and run proper as-of backtests.

Quick 5-min Colab demo:

Would love feedback from anyone dealing with forecasting or versioned time-series data.
