Sept 28 (Reuters) - Cloud-based data platform Workiva has received takeover interest from private equity firms Thoma Bravo and TPG, Bloomberg News reported on Wednesday citing sources familiar with the matter.

Private equity firms have taken several software companies including Anaplan and Zendesk Inc private this year.

Thoma Bravo this year has acquired cybersecurity firm SailPoint, agreed to buy Ping Identity Holding and has expressed interest in British firm Darktrace Plc and Australia's Nearmap.

Workiva, which currently has a market value of $3.4 billion, told Reuters it would not comment on market rumors and speculation.

Thoma Bravo and TPG also declined to comment on any potential takeover interest in Workiva.

The Iowa-based company's shares closed up nearly 18% on Wednesday. (Reporting by Akash Sriram and Bhanvi Satija in Bengaluru; Editing by Shailesh Kuber)
