Workiva Inc

Could not find a ticker for this position, may be a filing error

A cloud-based software platform that helps finance, sustainability, and risk teams turn data from hundreds of systems into linked, auditable reports — its products include Wdesk, Wdata, and Workiva Carbon. It was founded in 2008 in Ames, Iowa, as WebFilings by a group of entrepreneurs who wanted to end the error-prone copy-pasting of spreadsheets into SEC filings, and it rebranded to Workiva in 2014. The name, pronounced "work-eeva," was chosen to reflect the company's mission to change the way people work.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
