Ponder

Ponder was a data-science software company founded by UC Berkeley RISELab researchers (Doris Lee, Devin Petersohn, and Prof. Aditya Parameswaran) to commercialize the popular open-source Python libraries Modin (a drop-in pandas replacement that scales dataframe workflows with a single line of code) and Lux (automated visualization and intelligent data discovery inside notebooks). Backed by Lightspeed Venture Partners, 8VC, Intel Capital, and The House Fund via a $7M seed in March 2022, Ponder was acquired by Snowflake in October 2023. The ponder.io domain is now parked and no longer serves a live product, developer portal, or API; the open-source libraries remain the durable public surface.

Ponder is profiled on the APIs.io network. Tagged areas include Company, Data Science, DataFrames, Analytics, and Python.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ponder: open an issue to ask a question, or submit a pull request to add artifacts.
