Marc Sanderson’s Thirteenth Offer

Before Marc Sanderson could sell software to a woodworking shop, he had to work out what, exactly, he had bought. In the late 1990s, his business had four computers. None sat on his desk. To understand how information traveled, his team reached for whiteboards and string. They mapped forms, steps and handoffs, following something as ordinary as a customer’s name through the business. The diagram became a web. A cabinet, apparently, could have a very complicated childhood.

Sanderson had entered an industry where the finished object gets the attention. Wood has grain, weight and a smell. A misplaced estimate has none of those advantages. Yet he kept returning to the work that happened before a board reached a machine: deciding what a job required, getting drawings right, passing information along without introducing a fresh mistake. The software company that followed, INNERGY, grew from that preoccupation.

His route to founding it included an engineering degree, business school, a long search for something to buy and years running a Minnesota millwork operation. It also included learning to let other people run the business he had helped build. For someone who spends so much time explaining how work should move, knowing when to get out of its way is a useful qualification.

The thirteenth offer

The acquisition search was hardly confined to woodworking. Sanderson and his partner considered a deli-salad business, a fan manufacturer and a company that refurbished the hefty mobile phones of an earlier era. A salad company and a cabinet shop do not suggest an especially narrow investment thesis. What connected the search was his desire to own a business.

Offer number thirteen led to Ron’s Cabinets in 1997. Woodworking had a personal foothold: he had grown up working in a woodshop with his father. But familiarity with the material did not supply an operating system. By 1999, the business was writing its own software because the tools Sanderson wanted were unavailable.

Walter Wilkie was central to that beginning. Sanderson had written a class paper about him; the relationship became a business partnership and a long apprenticeship in ownership. A graduate-school assignment is usually filed away. This one acquired employees, overhead and a considerably more demanding marking scheme.

A custom cabinet, a repeatable route

Sanderson’s explanation of custom manufacturing starts with a practical inconvenience. Manufacturers of repeatable products can build their systems around a relatively stable object. A millwork shop gets asked to make unusual things. Its customers expect the difficult detail, the awkward fit, the piece that requires someone to figure it out.

He bought his first shop at twenty-eight with ambitions that ran ahead of his understanding of scale. Producing good work, he came to see, did not automatically make the operation easier to grow. The useful repetition lay in the journey a project took through the company. The finished pieces could differ while the steps remained recognizable.

That observation gave him something concrete to standardize: how a job moved from drawings through ordering, production and completion. His advice now is to begin with enough structure for people to understand the work and improve it. An elaborate process that employees ignore offers little comfort when a delivery date approaches. The goal is a routine people actually use.

The teacher kept showing up

Long before the recent acquisitions and product launches, Sanderson was a familiar education presenter at Architectural Woodwork Institute seminars, workshops and conventions. His 2017 speaker biography described him as both the owner of Wilkie Sanderson and a product advisor to INNERGY. Teaching ran alongside operating the shop, giving him another place to test whether an explanation made sense to the people doing the work.

His subject matter could be wonderfully unglamorous. At IWF in 2024, he taught job costing, working through materials, labor and expenses. He also joined Cassey Gibson to discuss the woodworking workforce. These are the conversations that seldom make the glossy photograph of the finished installation. They help determine whether the company can afford to make the next one.

The same pattern appears in his podcast conversations with business coach Dominic Rubino. One episode considers how banks assess cabinet shops and why owners should know their banker. Another tackles unpredictable scheduling, client communication and project flow. Sanderson repeatedly returns to the decisions surrounding the craft: financing it, planning it and understanding where the money goes.

“Knowledge without action is useless.”

The short statement fits a teaching practice built around application. An owner listening to him is being asked to reconsider an estimate, a schedule or a habit. Buying software still leaves a business with people who have to enter information, interpret it and do something useful with the result.

A mentor’s lesson travels

In the story INNERGY tells about RCS Millwork, Joe Keller remembers being mentored by Sanderson. The business had been working hard without enough visibility into costs and production. Keller’s recollection puts Sanderson’s role somewhere between software supplier and persistent questioner: plenty of physical activity could coexist with a poor understanding of profit.

Taber Company’s account supplies another example. Its team began with estimating before extending the system across other departments. The transition had a personnel setback when its original implementation champion had to be replaced. Later, better capacity information helped the business consider spreading a heavy January workload into neighboring months. The lesson involved both a tool and the person responsible for making it stick.

These accounts explain why Sanderson keeps education close to the product. The software has to fit a working organization with its own routines and loyalties. A clever report can remain untouched. A lesson that changes which work an owner accepts, or when a team releases it, has a chance of showing up in the accounts.

Learning to leave the shop

INNERGY began in 2015. Its development had a long runway inside the woodworking business, with profits from that operation supporting the software effort. Sanderson’s experience was unusually intimate: he had been responsible for the kind of company he was now asking to become a customer. That history also gave him plenty of assumptions to examine as the product reached other shops.

Meanwhile, Wilkie Sanderson was becoming less dependent on him. Employee ownership began in 2008. In 2024, he described his proudest achievement there in terms of the team’s ability to carry on without him. By January 2025, he was publicly describing his attention as fully committed to INNERGY, while the woodworking business continued under its own team.

There is a pleasing difficulty in that definition of success. A founder spends years making himself useful, then has to build an organization that can manage his absence. Sanderson’s public account of the handoff is affectionate rather than funereal. He compares the business to children who have grown up and moved out. The operating ideas were staying behind; their original advocate could move on.

Following the queue

The $44 million Mainsail Partners investment, announced in August 2024, gave INNERGY resources for product development, education and customer success. It was a sizable commitment to a very specific corner of manufacturing. Sanderson’s next moves stayed close to the customers already there.

The Microvellum acquisition was publicly announced in March 2025. Microvellum brought established design-to-manufacturing software and a team led by David Fairbanks. The companies emphasized continuity for existing customers while describing plans to connect their capabilities more closely. For an owner whose business depends on familiar engineering tools, the promise of progress arrives with a reasonable supplementary question: what happens to Monday’s work?

In May 2026, INNERGY acquired Archetype, bringing a 220-person drafting operation into its offering. The problem Sanderson described was specific: shops could sell projects faster than their engineering teams could produce drawings. Adding expert drafting capacity allowed him to address the queue with people as well as software. Customers could request that help within the platform and see where drawings stood.

August brought the launch of INNERGY Engineering. The browser-based CAD/CAM system lets several people work in the same project, connecting design information with manufacturing output. At IWF in Atlanta, Sanderson discussed the product with Will Sampson. The old concern was still recognizable: reduce the waiting and repeated handoffs that accumulate before production starts.

Room for the bruised apple

Sanderson’s leadership writing turns the demand for visibility back on himself. He encourages leaders to admit mistakes and make it safe for colleagues to report problems. He describes INNERGY’s habit of showing the bruised side of an apple, a more memorable teaching aid than another slide headed “values.”

His account of a company-wide system outage is a test of that idea. Staff organized communications, rerouted support and contacted customers. Updates went out every ten minutes. At a planned product release two business days later, the team raised the outage openly. He recalls customers appreciating the speed and candor. A software company gets few chances to demonstrate its philosophy more directly than when its software stops working.

There is also a life away from the operating diagram. Sanderson sings and takes part in community theater. In a July 2026 conversation about entrepreneurship and life, he discussed making room for family and fun, including regular date nights. The person interested in building systems has reasons to want some unallocated time after the work is done.

His career keeps circling a modest but demanding ambition: make it easier for other people to succeed at difficult work. That means teaching an owner to read a job differently, helping a drafter get a drawing finished, or handing an established company to the people inside it. The whiteboards and string belonged to an earlier chapter. The question they raised still has plenty of work left in it: where does the job get stuck?
