The lunch was supposed to last an hour. Dustin Marx and Steven Smith met at Jason’s Deli to talk about plumbing, which sounds like an excellent way to keep a lunch brief. Instead, they stayed all afternoon. Marx had built a company connecting rental property managers with contractors. Smith ran SND Plumbing. They kept talking about the people doing the work, how to treat them, and what sort of business might be worth building together.
Marx had arrived at plumbing by following a trail of other people’s expertise. He read books, watched repair videos, listened to home service podcasts, and sought out an operator he had heard on Roger Wakefield’s show. A lunch with that operator led to an introduction to Smith. Before there was an acquisition, there was a referral. Before there was a plan for scale, there was a conversation that ran through the afternoon.
In the summer of 2024, Marx acquired the small business that became Mother Modern Plumbing. Its starting revenue was about $15,000 a month. For someone returning from a venture-backed company, the scale was modest. The decision was quite deliberate.
Before the pipes, there were knives
Marx’s business education began with selling Cutco through Vector Marketing in 1999. He studied finance at Indiana University and went into management at Vector, eventually running its Gulf Coast Division from 2006 to 2013. Selling, recruiting, and leading people came well before the plumbing company. The products would change. The need to persuade someone, teach someone, and put a team together would travel with him.
Stellar, founded in 2016, applied those abilities to a sprawling coordination problem. Rental homes need repairs. Property managers need someone to handle them. Contractors need work. Getting those needs to meet reliably was the business. The company began as IFM Restoration and adopted the Stellar name in 2022, with Marx presenting the change as a continuation of its work for employees, property operators, contractors, and residents.
By December 2022, Stellar reported serving more than 150,000 properties and working with ten of the eleven largest single-family rental operators. It had created work for more than 8,000 contractors and resolved over 200,000 maintenance problems. Its $20 million Series B, led by Weatherford Capital, brought disclosed funding to $35 million at that point. The plan included more technology, more people, and more markets.
Those figures describe an enterprise with considerable reach. They also describe the distance between a founder and any individual job: many properties, multiple trades, a network of contractors. Marx later said that working across so many trades and markets left him wanting to concentrate on one. For his next business, he chose plumbing.
A successful exit still leaves a question
After stepping away from Stellar, Marx described a period of reading, reflection, and parenting. He had spent more than 20,000 hours building the company. Suddenly there was room to ask what should occupy the next stretch of his life. A mentor’s recurring joke about deciding what to be when he grew up had acquired practical significance.
He organized the decision around three questions: what work would remain meaningful when it became difficult, where his experience gave him an advantage, and what essential need he could serve. His reading included Brad Jacobs’ How to Make a Few Billion Dollars; his listening included David Senra’s Founders podcast. The next chapter would involve learning, but it would also use what he already knew about home services.
The size of the previous chapter needs a little precision. Marx has clarified that Stellar generated about $100 million in cumulative revenue over eight years. That is a different measure from annual revenue, and from a sale price. His move into a small plumbing operation is interesting enough without making the arithmetic wear a larger suit.
Starting smaller also changes what a founder can notice. A company coordinating thousands of contractors and a company working alongside its own plumbers give the boss different views of the work. At Mother, Marx’s accounts repeatedly return to individual conversations: an employee questioning a plan, a technician explaining a preference, a colleague describing what was missing. The operating story happens at conversational distance.
The boss takes the lower seat
At Mother, Marx has described drawing an organization chart with plumbers at the top. Operations, marketing, and finance support them. The chief executive supports the people supporting the plumbers. This gives the person arriving at a customer’s door a particular place in the business: the office exists to help that person do the job.
“Happy plumbers make happy customers.”
Dustin Marx
Marx’s explanation for the chart is unusually personal. Looking back on earlier ventures, he said he had built companies he would not have wanted to work at. Mother offered a chance to reconsider the structure. A founder can find that an uncomfortable admission. It is also a useful one, because it turns a conversation about culture into a question about the experience of being an employee.
The compensation policy gives the idea a financial consequence. Mother allocates half its profits to employees. Within that employee share, 15 percent goes into a retirement trust; the remainder is distributed according to roles. In weekly meetings, plumbers forecast the revenue and costs associated with their trucks. Materials, marketing, and apprentices become part of a business calculation they can see.
Marx has cited Les Schwab Tire Centers and The Great Game of Business as influences. His ambition is to help tradespeople understand the business around their craft and eventually lead operations themselves. The weekly numbers are a way to practice. A truck has a route, equipment, customers, and costs; learning to read its results gives the person driving it another kind of responsibility.
An employee asks for a different deal
The system did not arrive fully formed. Early in Mother’s development, an employee challenged the compensation structure. Marx’s account is that the team came together, discussed the problem, and redesigned the arrangement within three weeks. In the following month, he said, revenue nearly doubled. That is his reported sequence of events, rather than proof that one adjustment explains every dollar.
It sits alongside an expensive lesson in customer acquisition. Marx described spending nearly $60,000 on Google pay-per-click advertising through multiple agencies and finding that the approaches failed to deliver the results he wanted. A new name and an experienced founder did not exempt Mother from the ordinary work of earning trust. Customers still had to choose it. Plumbers still had to deliver.
Choosing the name was itself part of that work. Marx wanted Mother to suggest care, precision, and pride. He described the logo’s curves as an M, a pipe, and a winding entrepreneurial path. It is a name that can carry an expectation into the house before the technician enters. It also offers the considerable convenience of telling a customer, without any family drama, to call Mother.
The months that refuse to climb
Marx’s public account of growth includes stretches when the business stayed in place. In early 2026, he reported four consecutive months in the $750,000 to $800,000 revenue range. He listed missing capacity: recruiting, dispatch, installation management, phone coverage, and weekend service. Growth had become a staffing and scheduling problem with several moving parts.
April brought $966,000 in sales, he said, while completed revenue remained at $757,000. The distinction matters in a service business. Winning work and finishing work happen on different clocks. In June, he reported that May had finally passed $900,000 in monthly revenue. His description of growth had become a staircase, with landings long enough to inspect what was holding the company back.
By September, he was sharing another awkward month. August sales had exceeded July’s by about $75,000, yet revenue finished roughly $90,000 lower because the team could not complete all the work within the month. Booking performance and average ticket had also missed the plan. Posting those figures gave his business journal something more useful than a procession of personal bests: the inconvenience between the milestones.
A holiday reveals the founder’s job
After two weeks in northern Michigan in August 2026, Marx returned to a company that had sold $79,000 in a week against a usual weekly average of about $225,000. His reaction was to examine how much the organization still depended on his presence. Being missed can be flattering. In a growing business, it also leaves a rather conspicuous hole in the schedule.
He described a producer who valued their conversations on the drive home and a colleague who missed his energy at the weekly meeting. Marx took those observations as evidence of dependence on him. His response included asking leaders to notice when someone needed a conversation and sending leadership team members out with plumbers. The problem had appeared in sales numbers. Addressing it required spending time with people.
There is another schedule he has been changing. Marx used to prize being first into the shop. Now he describes taking his four-year-old to breakfast and then to school. There is chocolate milk, conversation, and giggling. With travel and late evenings sometimes taking him away, that morning gives father and son time they can count on.
He connects the change to his employees, who have their own versions of that morning at home. The ambition at Mother remains substantial: he has outlined a goal of fifteen Texas locations and $300 million in revenue by 2036. Those are future targets. Meanwhile, the business he is building has to make room for the people inside it. The next call matters. So does getting to breakfast.
