“You can't build a solid reputation on shaky foundations; it's all about getting the basics right, every single time.”

Mack Marks has been immersed in the world of plumbing and heating since leaving school at 16. He earned his NVQ Level 3 through a combination of college courses and apprenticeships, quickly developing a reputation for being thorough and reliable. For the past 15 years, he's worked as a foreman for an M&E subcontractor in Birmingham, overseeing domestic retrofit projects and smaller commercial installations. His current role involves managing a crew of four, a responsibility he takes very seriously. He believes strongly in the value of hands-on experience, often jumping in to help his team with particularly tricky tasks, but he also understands the importance of efficient management. His approach to work is deeply rooted in practicality; he values tools and methods that are robust, dependable, and get the job done correctly the first time. This extends to his personal life, where he prefers sensible financial planning and investing in things that last, like his classic Ford Transit van, which he's painstakingly restored over several years. He sees time as a valuable commodity, especially during the working week, and gets frustrated by inefficiencies that eat into billable hours or delay project completion. While he's comfortable with technology like WhatsApp for quick communication and photos, his reliance on paper job sheets and manual data entry into Excel reflects a cautious adoption of new digital workflows, often stemming from a 'if it ain't broke, don't fix it' mentality, coupled with a healthy skepticism about overly complex or expensive solutions. He recently had to navigate a complex variation on a kitchen refit where the client kept changing their mind about appliance placement, leading to significant extra pipework and wiring – a situation that highlighted the challenges of accurately capturing and billing for such changes using his current system.

Background & daily life

A day in their life

Mack's day starts around 6:00 AM. After a quick breakfast, he heads to the van, checking his phone for any overnight messages. By 7:30 AM, he's meeting his crew at the first job site – currently a domestic retrofit project in Moseley, fitting new heating systems. He spends the morning overseeing the installation, answering questions, and ensuring safety protocols are followed. He might spend an hour or two doing some of the more complex pipework himself. Lunch is usually a quick sandwich on-site. In the afternoon, he might visit a second site for a quote or to check on a previous job's progress, making notes and taking photos. He aims to finish on-site by 5:00 PM, then drives back to the depot or home, where he'll spend 30-45 minutes updating the Excel tracker and logging any variations before heading home for dinner.

Lifestyle

Mack lives in a semi-detached house in a well-established suburb of Birmingham with his wife, Sarah, and their two teenage children. His routine is dictated by early starts and the demands of his job. Weekends often involve a mix of family time, attending Aston Villa matches, tinkering with his beloved classic Transit van, or a quiet pint at the local pub with mates. He's not one for extravagance, preferring to save for family holidays or home improvements. Health-wise, he tries to stay active but admits long hours and the occasional greasy fry-up aren't ideal. Money is managed carefully, with a focus on ensuring bills are paid and there's a buffer for unexpected expenses.

Work life

As a working foreman, Mack is constantly balancing hands-on work with supervising his four-person crew. His days are a whirlwind of site visits, diagnosing issues, directing his team, and dealing with unexpected problems – a leaky pipe on a new build bathroom, a boiler needing an emergency fix in a terraced house, or coordinating with other trades on a light commercial refit. He juggles paper job sheets, takes photos on WhatsApp for client updates or to document issues, and scribbles notes in a worn notebook for any variations or extra work. The constant pressure is to get the job done right, on time, and without costly call-backs, before he can even think about updating the Excel tracker back in the van.

Relationships

Mack is married to Sarah, who works part-time as a school administrator. They have a solid, long-standing partnership. His two children, Liam (17) and Chloe (15), are his main focus outside of work. He has a close-knit group of friends from his football club and the pub, many of whom are also in trades, providing a strong informal support network.

How they decide

Mack is a pragmatic and evidence-based decision-maker. He weighs up the practical implications, cost-effectiveness, and reliability of any choice. He's not easily swayed by trends or hype, preferring to stick with what he knows works, but he will research thoroughly if a significant change or investment is required. He values input from experienced colleagues but ultimately trusts his own judgment based on years of practical experience.

How they sound

Speaks with a clear, no-nonsense Birmingham accent. His cadence is steady, often punctuated by practical observations. He uses common trade slang but avoids overly technical jargon unless necessary. He's direct and to the point, not one for flowery language or beating around the bush. He'll often start sentences with 'Right then,' or 'Look, the thing is,' and tends to avoid complaining about customers directly, instead focusing on the 'job itself'.

  1. What would stop you from trying Convoe (https://www.convoe.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).

    Right then, the main thing stopping me from trying this Convoe is the time. I'm already wrestling with paper job sheets, WhatsApp pics, and my notebook for variations. By the time I get back to the van, I've got to update the Excel tracker. It sounds like this tries to do that, but I'm not sure if it’ll just add another layer of admin. How does it actually integrate with what my lads are already using? We're not all glued to our phones. As for paying, I'd need to see how much time it actually saves. Maybe £20 per month per AI user, if it’s that good. But honestly, I’d need to try it first. It’s a bit of a gamble.
