Kiteworks announced a $456 million growth-equity investment on August 14, 2024, supplied by Insight Partners and Sixth Street Growth. The minority-stake deal included partial liquidity for existing stakeholders and put Kiteworks’ implied valuation above $1 billion; the company did not disclose an exact valuation.
Who invested $456 million in Kiteworks?
Insight Partners and Sixth Street Growth provided the investment, according to Sixth Street’s announcement dated August 14, 2024. The investors described it as growth equity, not a conventional venture-capital Series round. SecurityWeek characterized it as a minority-stake investment, while the announcement also called it a partial liquidity event.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is Kiteworks a file-sharing or managed-file-transfer company?
It spans both categories, and also covers email data communications. Its positioning is broader than a single-purpose file-sharing or file-transfer product: the Private Content Network is intended to bring sensitive-content exchanges across those channels under security, tracking and compliance controls. That description does not by itself establish which deployment model, certifications or integrations will suit a particular organization; buyers evaluating it should verify those requirements for their own environment.
