NinjaOne Inc., a startup with a platform for managing information technology infrastructure, today announced that it has raised more than $400 million in secondary funding.

The share sale marks the second extension of a Series C round that the company first closed in 2024. NinjaOne nabbed a separate $500 million follow-on investment last February. Its latest raise included contributions from Alphabet Inc.’s CapitalG fund, Sequoia Capital, ICONIQ and other prominent investors.

NinjaOne’s platform reduces the amount of manual work involved in managing IT assets such as workstations and cloud instances. A centralized dashboard enables administrators to monitor the configuration of upwards of thousands of devices. NinjaOne can, for example, flag employee devices with unencrypted hard drives that might expose data to hackers. It also provides tools that enable IT teams to fix such configuration issues.

A second set of features built into the platform eases patch installation. Downloading an operating system update onto thousands of employee devices can be a highly time-consuming process. According to NinjaOne, its platform speeds up the task by up to 90%.

One of the challenges involved in large-scale update rollouts is that patches sometimes contain bugs. As a result, administrators often delay the release of a new software release until they determine that it poses no reliability concerns. NinjaOne provides an approvals tool that enables companies to hold patches until they’re reviewed by the IT team.

Manual reviews sometimes miss faulty updates. NinjaOne’s platform includes an artificial intelligence tool that analyzes system logs, technical support forums and other data sources to find bugs. Additionally, the software highlights cybersecurity updates that should be installed urgently.

Downloading updates from the cloud isn’t always practical at edge locations that lack reliable connectivity. According to NinjaOne, its platform addresses the challenge with a feature that caches patches on a local server. Employees can download the updates from the cache instead of the cloud to save bandwidth.

NinjaOne’s platform also eases several other IT tasks. One built-in tool enables administrators to remotely log into malfunctioning devices for troubleshooting purposes. Another feature, NinjaOne Documentation, can store an IT team’s internal technical support guides. It also automates some of the work involved in keeping the documents up to date as the systems and best practices they describe change.

NinjaOne says that its installed base includes nearly 40,0000 organizations. The company’s annualized recurring revenue topped $500 million in 2025. Last quarter, it became profitable.

“Because we are profitable, this raise was never about needing capital to grow,” said co-founder and President Chris Matarese. “We had a long list of firms interested in providing financing, and we used this round as an opportunity to pick the best possible partners.”

The company will use the capital to speed up growth initiatives.
