DateStageInvestorsRaisedValuationDeal Summary
Aug 2024Undisclosed stageInsight Partners (lead); Sixth Street (lead)$456M$1BKiteworks, a San Mateo-based cybersecurity company specializing in secure content communications via its Private Content Network (PCN) platform, supports file sharing, managed file transfer, and email for compliance with global standards including FedRAMP authorization. Formerly Accellion, it rebranded after a 2021 data breach affecting legacy services and clients like Morgan Stanley and Shell. The platform enables secure data sharing for enterprises such as SEC, Pfizer, Harvard, KPMG, NHS, Target, Honda, and Israeli banks, HMOs, and cyber firms. On August 14, 2024, Kiteworks secured a $456 million growth equity investment co-led by Insight Partners and Sixth Street Growth as a minority stake partial liquidity event, valuing the company at over $1 billion and achieving unicorn status. Less than $100 million is primary capital for the company, with the rest as secondary sales to buy out veteran investors, creating board seats for partners from both firms. Total funding raised historically reaches $592 million, following a $120 million round in 2020 led by Bregal Sagemount. Proceeds will fuel R&D, team expansion in engineering and marketing, business development, and an aggressive M&A strategy that has already acquired four startups, alongside organic growth described as 'Rule of 50-level'—combining revenue growth and EBITDA expansion. CEO Jonathan Yaron highlighted innovations like Next-Gen Digital Rights Management to address data tracking challenges amid regulatory focus. The round underscores investor confidence in Kiteworks' leadership in the secure data transfer market, positioning it against cybersecurity peers like Abnormal Security amid surging sector funding, with plans for further non-organic growth including potential Israeli acquisitions.
Apr 2020Undisclosed stageBregal (lead)$120M-Kiteworks, formerly Accellion, is a secure data sharing and content communications platform provider focused on consolidating, controlling, and securing sensitive third-party communications via an enterprise content firewall. The company raised $120 million in a financing round around April-July 2020 led by Bregal Sagemount, with Baring Private Equity retaining a significant stake from prior investments. This growth capital was intended to accelerate adoption of its platform in sectors like software and digital infrastructure. Bregal Sagemount, a growth-focused private capital firm managing $3.5 billion, led the investment through partners Michael Kosty, William Breskman, and Daniel Eatroff. The deal was announced via press releases from Accellion and Bregal Sagemount, highlighting strategic support for market-leading companies in high-growth areas. Legal counsel included Pillsbury for Accellion and Goodwin Procter for Bregal Sagemount. Kiteworks later achieved unicorn status with a valuation over $1 billion in a 2024 $456 million growth equity round from Insight Partners and Sixth Street Growth, which included partial liquidity. Bregal Sagemount exited its stake by 2024, with ownership shifting to Insight Partners, Sixth Street, Baring Private Equity Asia, and employees. Founded in 1999 and based in San Mateo, California, Kiteworks serves industries requiring secure file sharing, email encryption, and compliance with standards like GDPR, HIPAA, and CMMC. It faced challenges in late 2020 from exploits in its retired legacy Accellion FTA product, unrelated to the modern Kiteworks platform. Total funding raised by Kiteworks reached approximately $592 million by 2024 across multiple rounds, positioning it in the competitive cybersecurity market for secure content communications and zero-trust data protection.
