Cairn Applications
Cairn Applications builds cloud software purpose-built for waste hauling operators. The platform manages the full operational workflow of a waste hauling business, including order management, routing and logistics, asset tracking, billing, and customer communication, across dumpster, route, and transfer station operations.
Waste management is an essential but historically underserved market when it comes to software. Operators in this space have long relied on generic tools that were not built for their specific workflows. Cairn Applications fills that gap with purpose-built functionality that reflects how waste hauling businesses actually run, from dispatch and driver assignment through invoicing and customer account management.
The company joined the Solen portfolio in December 2025 through a fast and efficient process. From first substantive conversation to a signed agreement, Solen moved quickly and clearly, which founder James Moser has cited as central to the experience. It is a strong example of what is possible when a founder is ready and an investor is organized and decisive.
Post-investment, the team has access to Solen's operating support and product investment resources, with the long-term goal of building the definitive software platform for waste hauling operations.
“Integrating into Solen's platform will allow us to focus exclusively on our core strengths: building superior products and providing best in class customer support. We're excited to work with Solen's team of experts to build a better future for our customers and our employees.”
— James Moser, Founder, Cairn Applications
