“You can't fix a leaky pipe with a spreadsheet, but you sure as hell can't fix a business without knowing where every wrench is going.”

Robert Koelpin is a fixture in the Dallas plumbing community, having built his reputation from the ground up after earning his trade certification in the early 2000s. Starting with a single pickup truck and a hand-me-down toolbox, he expanded his operation to five trucks and eight employees over the last decade, driven by a relentless work ethic and a deep understanding of the trade. Despite his success, Robert remains deeply attached to traditional methods, refusing to digitize his core planning processes beyond basic Excel usage. He views technology as a useful tool only if it solves a specific, immediate problem without adding complexity. Recently, he faced a crisis when a sudden snowstorm in January caused multiple trucks to get stuck, leading to missed appointments and angry customers. This incident forced him to re-evaluate his static routing system, though he remains hesitant to invest in expensive software that promises automated optimization. He currently relies on his own map-reading skills and gut instinct to navigate the city's chaotic traffic patterns. Robert is financially secure but cautious, viewing every dollar spent on new tools as a gamble against his hard-earned savings. He is increasingly aware of the toll manual planning takes on his health and family life, yet he struggles to find a solution that respects his need for control and simplicity. His recent decision to hire a younger, tech-savvy apprentice was an attempt to bridge the gap between his traditional methods and modern efficiency, though the cultural friction remains high. Robert's world is defined by tangible results: water flowing, drains unclogged, and trucks returning to the depot on time.

Background & daily life

A day in their life

Robert wakes at 5:30 AM to a quiet house, brewing a pot of strong coffee before checking the weather forecast for the Dallas metro area. By 6:15 AM, he is at the warehouse, greasing down the fifth truck and ensuring the inventory racks are stocked. He spends 45 minutes at his desk, sketching out the day's routes on graph paper, calculating drive times manually, and noting potential traffic bottlenecks near downtown. At 7:00 AM, he conducts the morning huddle with his eight drivers, handing out printed manifest sheets and giving verbal instructions. He spends the rest of the morning monitoring phone calls, approving parts orders, and stepping onto job sites to resolve technical disputes. Lunch is usually a quick sandwich at his desk while answering emails. Afternoon hours involve driving to a site to inspect a major installation, ensuring the crew follows safety protocols. He returns to the office by 5:30 PM to update the spreadsheet, reconcile today's expenses, and prepare the schedule for tomorrow, ending his day just as the sun sets over the city skyline.

Lifestyle

Robert lives in a modest but well-maintained brick home in North Dallas, a suburb that balances his work proximity with family privacy. His mornings are rigid; he rises at 5:30 AM, drinks black coffee while reviewing the day's physical dispatch sheet, and rarely skips this ritual. He is physically active, often walking the perimeter of the job sites to inspect work personally rather than delegating entirely. His weekends are split between family time with his wife, Linda, and working on his personal projects: restoring an old Ford F-150 in the garage. Financially, he is conservative, preferring cash reserves over aggressive investments, and pays off credit cards monthly without carrying interest. Socially, his circle is tight-knit, consisting mostly of other small business owners and former apprentices who have become friends, meeting occasionally at local BBQ joints or the Elks Lodge.

Work life

As the sole dispatcher and decision-maker, Robert's office is a cluttered desk in the back of his warehouse, dominated by a large whiteboard and stacks of printed manifests. He manages five trucks, each assigned specific zones to minimize drive time. His day begins with handwritten notes, which he then transcribes into a master Excel spreadsheet, cross-referencing job durations against driver availability. He values face-to-face interactions with his crew, often standing on the loading dock to brief them personally. The pressure comes from unpredictable emergencies—burst pipes or sewage backups—that disrupt his meticulously planned routes. He relies heavily on his own intuition and experience to judge how long a job will take, often underestimating complex installations due to his confidence in his team's speed.

Relationships

Robert is married to Linda, who handles the front-desk reception and billing, acting as the buffer between him and angry customers. Their relationship is built on decades of shared sacrifice; she trusts his instincts, while he trusts her with the finances. He has three sons, though only one works in the trade, often clashing over management styles. His closest professional confidants are his two longest-serving foremen, whom he treats like brothers. He is active in the local Chamber of Commerce, where he advocates for fair labor practices among contractors, though he rarely speaks unless necessary.

How they decide

Robert makes decisions slowly and methodically, relying on past experience and tangible evidence rather than abstract promises. He is highly skeptical of 'magic bullet' solutions and prefers tools that offer immediate, visible utility. Before committing to any change, he tests it rigorously on a small scale, often running parallel systems to compare results. He values peer recommendations from trusted industry veterans over marketing materials, and if a tool requires significant training or disrupts his workflow without clear ROI, he abandons it immediately.

How they sound

Robert speaks with a grounded, Texan cadence—slow, deliberate, and devoid of corporate jargon. He uses phrases like 'let's see what the numbers say' or 'that ain't gonna fly.' He avoids overly technical terms, preferring plain English to describe problems. He doesn't use slang casually but has a dry, practical humor that surfaces when discussing difficult clients or broken equipment. He is direct and honest, often saying exactly what he thinks without sugarcoating, and tends to pause frequently to gather his thoughts before answering complex questions.

  1. What would stop you from trying Routing24 (https://routing24.com) this month? Be specific about how you handle this today. Also say the maximum you would pay per month in USD (0 if nothing).

    Routing24, huh? What would stop me? Well, right now, I've got my system down. I wake up, I grab my coffee, and I'm at the warehouse by 6:15 AM. I sketch out the routes on graph paper, figure out the drive times myself, and then I brief the guys face-to-face. It's what I know. This whole 'AI agent' and 'MCP server' sounds like a lot of fancy tech I don't need. My biggest worry is throwing money at something that doesn't work or is too complicated for my crew to use. I'd need to see it actually save me time and keep customers happy, not just promise it. As for paying for it, I wouldn't pay more than $0 per month. I'm not looking to spend money on software right now.
