Node.js startup NodeSource Inc. today said it has raised $17.5 million in new funding in a Series B round that included Silicon Valley Bank, Industry Ventures, Crosslink Capital and RRE Ventures.

Founded in 2014, NodeSource builds products focused on Node.js security and performance for enterprise users. The only commercial provider specializing in enterprise Node.js services, the company offers its flagship N|Solid Node.js platform to provide real-time insight into application performance and security.

Node.js is an open-source, cross-platform JavaScript run-time environment for executing JavaScript code server-side that is becoming increasing popular for running data applications at scale. One of the recent adopters of the platform was Twitter Inc., which told SiliconANGLE’s theCUBE in August that it had adopted Node.js for use with its Twitter Lite app because of its lightweight nature and popularity among its engineering team.

NodeSource has a growing roster of customers including well-known names such as Citadel, Comcast, Condé Nast, Delta Airlines, Goldman Sachs, Mastercard, and PayPal.

“Our Node.js solutions are powerful tools for enterprises that need to run mission-critical applications on JavaScript,” NodeSource founder and Chief Executive Joe McCann said in a statement. The new investors “validate the strategy behind N|Solid and NodeSource Certified Modules.”

Including the new Christmas Day funding, NodeSource has raised $33.4 million to date. The company said it would use the funding to grow its engineering, support and global sales teams “to better serve customers as they create and deploy mission-critical and secure applications, leveraged by the power and low cost of the open source community.”
