Founded in 2008 by James Moser, Cairn Applications develops SaaS products used by waste operators across the United States and Canada. The company supports more than 350 customers, manages over 65,000 dumpsters, and facilitates nearly $150 million in annual commerce.
Cairn’s flagship platform, Box Tracker, is designed to manage the operational backbone of independent dumpster companies, including order management, logistics, billing, merchant services, asset and employee tracking, navigation, CRM, and automated customer communication. Cairn also offers Scale House, which supports landfill and transfer station operations, and Route Tracker, a solution for predictable route businesses such as commercial trash service, curbside pickup, and port-a-potty rentals.
"Someone once remarked that Cairn Applications was too small to go big and too big to stay small; its acquisition by Solen Software Group will change that dynamic,” said James Moser, Founder and President of Cairn Applications Inc. “Integrating into Solen’s world class platform will relieve Cairn of operational friction, surround it with competence in key areas such as business, marketing, and finance, and allow us to focus exclusively on our core strengths, namely 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.”
“Solen is a permanent home for enduring, customer-centric software companies,” said Alexander Spencer, Founder and CEO of Solen Software Group. “We seek out businesses with deep customer trust, strong domain expertise, and teams committed to long-term customer centricity. Cairn’s exceptional customer orientation and leadership in waste disposal logistics management software make it a natural fit for Solen. We’re excited to partner with Jim and Angela Moser and the Cairn team to reinforce and expand our presence in this industry while preserving what makes the company special and expanding upon what the Moser family has built. We are proud of the hard work the Moser family instilled—stewarding the business successfully for decades to enable a smooth ownership transition”
Cairn Applications will continue operating with autonomy, with Solen supporting the business through long-term ownership and optional shared services, allowing the Cairn team to remain focused on product development and customer support.
