Northern Ireland tech firm Cloudsmith has secured £2.1m in funding in one of the biggest early stage rounds for a start-up.
Cloudsmith is a "software as a service" business, which offers a platform to developers, operators and vendors who need to accelerate their product development.
The company said it will use the funds to ramp up research and development, and marketing.
And it hopes to launch a world-first service to help make software delivery more resilient.
The funding round was led by Frontline Ventures and co-investors MMC Ventures, and by Techstart Ventures through its Invest NI fund Techstart.
Cloudsmith chief executive Alan Carson said: "We believe that the concept of provenance will play a defining role in the future of software security and quality. All companies need end-to-end visibility and control of the assets in their software pipelines."
Steve Collins, partner at Frontline Ventures, said: "The guys are building what is in effect a foundational element for the next stage in the evolution of software development and distribution.
"Protecting developers and businesses from the chaos of public software will be a game changer."
Dan Bailey of MMC Ventures said it had been "impressed by the team's execution and vision in bringing this control and visibility to developers".
Hal Wilson of Techstart Ventures added: "This investment is a clear vote of confidence in the Cloudsmith team and their ability to execute."
Mr Carson and co-founder Lee Skillen formerly worked at Belfast-based Wombat Financial Software Ltd/NYSE Technologies. They set up Cloudsmith with Peter Lorimer.
