Collibra, a company that wants to help firms understand data governance, announced a $58 million Series D funding round today led by Iconiq Capital and Battery Ventures.

All of the investors involved in this round were coming back for another dip in the well. In addition to Iconiq and Battery Ventures, early Collibra investors Dawn Capital, Index Ventures and Newion Investments also participated. This round follows a $50 million Series C round almost exactly a year ago and brings the total raised to date to over $133 million, according to the company.

Collibra CEO and co-founder Felix Van de Maele would not discuss the valuation of today’s deal, only saying, “We don’t comment on our valuation, but it’s a big valuation increase versus the last round,” he said.

Iconiq is interesting because as TechCrunch’s Ingrid Lunden pointed out in the Series C story, it’s not just an investment company. It also acts as family office for the likes of the Zuckerbergs, Sheryl Sandberg, Reid Hofmann and Jack Dorsey.

As for what Collibra does, as companies gather ever more data, a problem arises. How do you understand what data you have, who has valid access to it and move it through a workflow to your data analysis tools?

That’s precisely what Collibra takes care of for large organizations like EMC, Holland America and Verizon (which owns this publication). “Most large organizations are in data chaos,” says Van de Maele. “We help them understand what data they have, where they store it and [understand] whether they are allowed to use it,” he said.
