The Company Behind 65,000 Dumpsters
Founded in 2008 by James Moser, Cairn Applications builds cloud software purpose-built for waste operators across the United States and Canada. Its flagship platform, Box Tracker, runs the operational backbone of independent dumpster companies: order management, logistics, billing, merchant services, asset and employee tracking, navigation, CRM, and automated customer communication. Two further products, Scale House and Route Tracker, support landfill and transfer station operations and predictable route businesses such as commercial trash service, curbside pickup, and portable toilet rentals.
The scale is quiet but serious. Cairn supports more than 350 customers, manages over 65,000 dumpsters, and helps facilitate nearly $150 million in annual commerce. This is mission-critical software in the truest sense. When it works, an entire industry runs smoothly in the background.
Too Small To Go Big, Too Big To Stay Small
Every founder reaches a point where the company's ambition outgrows what a single owner can carry alone. James Moser described that moment memorably.
"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."
For a company like Cairn, the question was never simply about a number. It was about how to give a durable, customer-loved product the room to grow without losing what made it work in the first place. That is a hard thing to find. Many partners are built around a short timeline and a future handover. Cairn was looking for the opposite: a permanent home.
Relief From Operational Friction, Focus On The Core
The clearest change a permanent home brings is focus. In Moser's own words:
"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."
This is the heart of how Solen operates. The non-core work that pulls a small company's attention, such as finance, marketing, and back-office operations, is supported through optional shared services. That frees the team to spend its time where it matters most, on the product and the customer, rather than on the administrative weight that grows with every year.
Continuity, By Design
A transition can be disruptive, or it can be quiet. Solen is built for the quiet kind. Cairn continues to operate with autonomy, with Solen supporting the business through long-term ownership and shared services where they help. The brand, the products, and the customer relationships stay in place.
Leadership has evolved smoothly rather than abruptly. Founder James Moser has stepped back from day-to-day leadership, and Jason Rumsey has been appointed CEO and General Manager of Cairn. The handover was designed to protect what the Moser family built over more than fifteen years, not to unwind it. The people who understand the product and the customers are still the people running it.
A Partner That Thinks In Decades
Solen is a permanent-capital firm. It holds and grows mission-critical software businesses for the long term, with no predefined exit, and reinvests in people, product, and customer outcomes. That long horizon is what makes a genuine permanent home possible. There is no clock counting down to the next handover, so decisions can be made for the years ahead rather than the next reporting period.
"Solen is a permanent home for enduring, customer-centric software companies. 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," said Alexander Spencer, Founder and CEO of Solen Software Group.
What It Means For Cairn's Customers
For the waste operators who rely on Box Tracker every day, the most important outcome of a transition is simple: nothing they depend on breaks. The support stays. The product keeps improving. The team they trust is still there.
A permanent home is, in the end, a promise to the customer as much as to the founder. The same focus that drew Cairn's customers to it in the first place, superior products and best-in-class support, is exactly what the transition is designed to protect and strengthen.
Thinking About Your Own Next Chapter?
Cairn's story is becoming a familiar one at Solen. A founder-built, mission-critical software company finds a permanent home, keeps its identity, and gains the support to focus on what it does best. The founder gets to choose their next chapter, the team keeps building, and the customers barely notice the change, except that the product keeps getting better.
