Ask HN: How can i create commercial value from open data?

Depends on what you mean by Open Data.

There are lots of companies that aggregate ranking/keyword data from Google, package it and sell it as a product to SEO companies. Examples include WordTracker, SEMRush, Moz, etc. It's data you and I can get through Google ourselves, but it's almost impossible to get in aggregate.

It depends on how you package the data. You need to present it in a way that can be actionable and help someone towards a business problem.

I mean the data the government releases to the public. e.g data.gov datasets

Oh, well IMO, nobody really wants to pay for that data, no matter how you aggregate it. it's why the gov gives it out for free :)

Refer to patio11's comment in:

He mentions ideas for datasets from data.gov

Thanks will check it out

For example numbers are open, but very huge primaries calculate not so easy.
