Two founders, one big ambition

Cloudsmith began with Alan and Lee, who shared a vision of making software distribution simpler, safer and more reliable. They saw an opportunity to solve a growing challenge for software teams and build something better.

What started as an idea became the foundation of Cloudsmith, driven by curiosity, determination and a belief in what was possible. Their founding vision continues to shape who we are, the Tao of Cloudsmith, and where we’re going next.

Turning an idea into a business

Joining the Ignite Accelerator marked an important step in our journey. It gave us the opportunity to develop our vision, challenge our assumptions and begin turning an ambitious idea into a business with real potential.

It was an early lesson in what it takes to build a company: curiosity, resilience and a willingness to learn quickly. These qualities helped establish the culture we continue to build on today.

Investing in our vision

Our first major investment came from Frontline Ventures, MMC Ventures and Techstart Ventures. Their backing helped Alan, Lee and the growing team turn Cloudsmith’s vision into reality, investing in product development and bringing our technology to market. It was an important first step in building a global software company from Northern Ireland.

Building for the world’s most demanding teams

As our ambitions grew, we focused on making Cloudsmith ready for the needs of enterprise customers. That meant developing a platform that organisations could rely on as their software operations became more complex and their security requirements more demanding.

This stage challenged us to think bigger, build stronger foundations and raise our standards. It helped shape Cloudsmith into a platform designed to support organisations at scale.

Building a home for our growing team

As Cloudsmith grew, so did our ambitions. Moving into the Scottish Provident Building in the heart of Belfast was a milestone that reflected how far we’d come, bringing our growing team into a space that matched our momentum.

It marked a new chapter for Cloudsmith, strengthening our roots in Belfast while laying the foundations for everything still to come.

Growing from Northern Ireland

Northern Ireland has been an important part of Cloudsmith’s story from the beginning. Support from Invest Northern Ireland helped us to continue developing our business, strengthening our capabilities and pursuing opportunities in international markets.

Our roots remain an important part of who we are. We are proud to be building a global technology company from Northern Ireland, contributing to its growing technology community while serving customers around the world.

Accelerating our growth

Led by Tiger Global, our Series A brought investment from Shasta Ventures, Sorenson Capital, Amaranthine, Leadout Capital, Scott Johnston, and Sarah Friar, alongside existing investors Frontline Ventures, MMC Ventures and Techstart Ventures. Support from experienced technology leaders and investors gave us the resources to grow our team, develop our platform and expand internationally.

Recognition in awards

Sponsored by MCS Group, the Digital DNA Awards celebrates excellence and innovation across the Northern Ireland tech sector, recognizing the achievements of individuals and organisations that are driving digital transformation and shaping the future of technology. We were delighted to win the prestigious award of Small Company of the Year.

Defining who we are and where we’re going

As Cloudsmith evolved, so did the way we presented ourselves to the world. Our rebrand was an opportunity to bring our identity in line with the company we had become and the ambitions we had for the future.

It represented more than a new look. It was a chance to clarify our story, strengthen how we communicate our value and give our growing team a shared identity as we continued building the business.

Leading Cloudsmith into its next chapter

In 2023, Glenn Weinstein joined Cloudsmith as CEO, working alongside co-founders Alan and Lee to drive the company’s next phase of growth. Bringing experience from Twilio, Glenn added fresh leadership and a global perspective as Cloudsmith continued to scale.

Together, Glenn, Alan and Lee are helping shape Cloudsmith’s future, building on the founders’ original vision and strengthening our ambition to become a global leader in software supply chain management.

Building on our momentum

Strengthening our roots and supporting the community

As Cloudsmith grew, so did our responsibility to give back to the tech community that helped build us. Alan joining the Software NI Industry Board was a natural step in bringing our team’s experiences to the table and helping shape the future of Northern Ireland's software sector. It’s an opportunity to mentor local founders, advocate for early-stage investment, and help regional software businesses scale globally just as we did.

Making history, building the future

In April 2026, Cloudsmith secured a $72 million (£53 million) Series C investment, the largest venture capital funding round ever raised by a Northern Ireland-based technology company. Led by TCV, with participation from Insight Partners and existing investors, this landmark investment marked a defining moment for Cloudsmith and the wider Northern Ireland tech industry.

With this backing, we’re accelerating product development, expanding our global reach and building the foundations for our next phase of growth. For our team, it’s an opportunity to be part of something extraordinary as we continue to scale our ambitions and shape the future of software supply chain control and security.
