You can give your sister a job title and a salary and get somebody who outperforms your last three hires. Founders are doing it right now, with husbands, wives, brothers, mothers and grown-up children on the payroll. If even just reading these words makes you uncomfortable, bear with me. The results show up in revenue and in the hours the founder gets back every week.

I have worked with my husband for 12 years. My mum ran sales for seven years at the social media agency I founded at 22 and sold in 2021. Best thing ever, both times. Neither cost me the relationship underneath it. If anything, they made it stronger.

So I asked LinkedIn for the single rule that makes it work. Founders replied with the arrangement they built with a wife, a brother, a mother or a daughter, and the business result it produced.

One took over as chief executive of the company her mother started in 1994. Another divides an entire family-first company by the results of a personality test. A third shipped a working product with her husband faster than a funded team would manage. Here are the five rules they use, and the reason the arrangement breaks down when it fails.

Why you should hire family members, and how make it work, by founders already doing it

You’re already on the same wavelength

Rehina Kuts co-founded Profigent AI with her husband two years ago. Her tip begins with three words. "Marry your CTO. I bring the idea, he ships it before I've finished the sentence." A new hire spends the first quarter working out how you think and what you mean when you say something is nearly right. Your husband did that within three weeks of meeting you. For free.

Jacob Bennett builds Crux Analytics with his brother Nathan, and describes what they get from it as "explicit trust and near-psychic communication". His second observation is the one to copy. " Lean into the fact that your family culture becomes the business culture. " That transfer happens whether you plan for it or not, so decide early which parts of how your family behaves belong in client calls. Kuts and her husband shipped a full SaaS product in 35 days. Onboarding costs nothing when there is nobody to onboard.

Take a psychometric test, then act on the results. Vivien Wong co-founded Little Moons with her brother Howard in 2010, and that is how the two of them split a mochi ice cream company now stocked in more than 30 countries . "We identify each other's strengths and weaknesses and use that to divide roles," she said. A test does something a conversation between siblings cannot. It gives you a neutral third party to blame for the answer.

Katie Achille has worked with her mother for 14 years and recently became chief executive of the company her mother founded in 1994, while her mother moved into the chief strategy officer role. Rearranging the top job inside a family is the hardest version of this, and they did it by looking at who fits the work now. "Set your egos aside and remember why you chose to work together," Achille said. Review the job titles in a family business as closely as you review anyone else's. Every two years, at least.

Say which hat you are wearing

Under pressure, a family reverts to the roles it had 20 years ago. Tav Szabó spent years building programs with his big sister before starting Log.os, and he described the effect. "Families default to old roles under pressure faster than any other team does." His fix is the most useful sentence anyone gave me. "Separate the role from the relationship, out loud, before you start." He tells his sister when he is speaking to her as her business partner. Your birth order comes back the moment a launch goes wrong.

Kayane Watson has worked with her husband Simon for 12 years and enforces the same separation with a clock. "I create a hard line between Simon my husband and Simon my business partner. Same person, completely different conversation." Their rule is no business talk after 8pm and never in the bedroom, and it restarts at 9am once the life admin is done.

Nick Baines, who works with his sister Alicia at Nara Communications, protects the other direction with what he calls "sibling hangs". A walk around a London park, or their local football team playing. Both relationships need a place in the calendar, or the business one takes every hour.

Explain more than feels necessary

Closeness makes people lazy about explaining things. Dr. Katie Barge has worked with her husband for eight years building The Nurture System, and her warning is this. "Don't mistake closeness for communication. The people who know us best are often the people we assume should simply know what we mean." Write the roles and the expectations down anyway. In a document, the way you would do it for somebody you met last week.

Jenna Farmer hired her dad two years ago and her sister-in-law about 18 months ago. "Have a clear framework of expected outcomes," she said. "Don't assume the knowledge in your brain is common knowledge and break things down clearly." What that removed was her feeling that she could not delegate. Since the two of them joined, Farmer has had the time to write her first business book and launch a podcast, and her sister-in-law left the teaching job she wanted to leave. Delegating to family fails for the same reason delegating to anyone fails. The instruction was never given.

Decide how decisions are ultimately made

Two founders gave opposite answers to the same question, and both are right. Jelena Skene has been with her husband for 14 years and is building her second company with him at Pressflow. "Know which one is the boss. Who has the final say. Otherwise you end up in a headlock most of the times and nothing gets done." Skene picks complementary skills on purpose, a builder and a growth marketer. Two people who are good at the same thing will argue about the same job for a decade.

Thomas Danielsen has worked with his wife for 11 years across Groupmenus.com and DMC Baltic, and he drew the line in a different place. "I might be the founder and the CEO, but I'm not her boss, and I don't tell her what to do." They agree the strategy together, and each of them decides how to deliver their part of it. Both versions function. Somebody wrote the rule at the start, before there was anything to argue about.

Could hiring family members be the right move for your business?

Lili Marocsik would not do any of this. "Many people could do whatever job we're talking about," she said. "But if I lose them as a family member, that position can not be filled." She is right about the stakes, but the conclusion is for you to decide. Some people believe they could make it work. Others believe they never could. Both are right. These founders treated the high stakes as the reason to set the rules from day one. Give them the work that fits their strengths, agree who decides when you disagree, and explain the thing you assume they already know. Do that, and you get a colleague who was on your side before you paid them.
