Working with your romantic partner isn’t just a niche phenomenon; it’s a growing trend. A recent study from the National Library of Medicine reveals nearly one in four U.S. small businesses are run by romantic couples. Yet, for all the talk of “power couples” in the startup world, precious little unfiltered insight exists on what it actually takes to share a bed, a budget, and a booming enterprise. For many, the lines between personal and professional don’t just blur; they cease to exist.

My husband, Joe, and I are the founders behind Serenity Kids, now the fastest-growing shelf-stable baby food brand in the U.S. Our origin story is uniquely intertwined with our personal one: the business was our first “baby,” meticulously nurtured from a shared frustration with the unhealthy baby food aisle. Our second? A literal, adorable human baby who is, unbelievably, seven this year.

As we scale a multimillion-dollar company while simultaneously navigating the exhilarating chaos of parenthood, I’ve gained an interesting perspective on the strategic moves and nonnegotiable rules that keep our marriage, and our company, thriving.

The Nonnegotiable Boundary That Saved Our Marriage

It sounds counterintuitive for founders whose lives are inextricably linked to their venture: put a hard stop on work discussions once you walk through the front door. But for Joe and me, this rule became the lynchpin of our relationship’s resilience.

In the early days of Serenity Kids, it was 24/7. Every meal, every car ride, every evening was a business meeting. Our passion was relentless, but I quickly realized the constant operational debriefs were eroding our identity as a couple. We were colleagues who lived together, not partners.

The encroachment was subtle. We’d be dissecting strategy over dinner or debating a supply chain hiccup right before bed. I realized that I missed him. And I had no idea what was truly happening in my partner’s life outside of work. The breaking point was Joe sleeping in the guest room because we’d had yet another work fight at bedtime. Those nights were disconnecting and actually set us back—both personally and professionally. Because close connection is our special sauce. Personality-wise, we are total opposites in every way—he’s an extrovert while I’m an introvert, I’m a perfectionist while he’s a “good enough” kind of guy, etc. So when we’re disconnected, we’re each operating as only half of a complete whole. I knew we needed a sacred space where we could simply be Serenity and Joe, disconnected from our job titles.

Our solution: an unwavering commitment to compartmentalization. Of course, genuine emergencies warrant discussion. But the default is clear: once we’re home, we consciously shift gears. We discuss our day as parents and individuals. We prioritize connecting on a human level over any work-related issues. We have 1:1 meetings on the calendar three times a week just to discuss work. And if either one of us tries to bring up a work topic, we say “put it on the agenda!” We also have dedicated date days or date nights where we commit to avoiding both work and kid talk, so we can focus on each other, as well as quarterly vision retreats where we visualize the future of our relationship, family, and business. This rigorous boundary, challenging as it was to implement initially, has proven invaluable. It forces hyperefficiency during work hours and provides essential emotional bandwidth to nurture our romantic relationship, separate from the relentless demands of the business.

Strategic Division of Labor

In any cofounder dynamic, clear role definition is paramount. When you add parenting to the equation, that clarity shifts from crucial to existential. For Joe and me, this has been a huge area of growth and evolution.

For the first several years after we had our daughter, I had the constant hum in my head that most working moms experience. “What’s for dinner? Who’s handling bath and bedtime tonight? What meetings do I have today and what should I wear?”

For a long time, I wrestled with that mental load. Not just about completing the task, but all the thinking, planning, and worrying that drained my energy. I wasn’t sleeping well, I wasn’t eating well, and I just wasn’t taking care of myself. While Joe watched TV at night, I stayed up late washing bottles, ordering next-size-up baby clothes, and researching Della’s latest mystery rash. All while still working full time plus managing our family’s finances and anything that required paperwork.

I was miserable. And after a brush with death from COVID pneumonia, I knew something had to change.

I found the Fair Play method by Eve Rodsky, and my mind was blown. I now could see the mountains of invisible work I had been doing since Della was born that Joe had no idea even existed. After some hard conversations and Joe’s willingness to experiment with a different way, the constant weight began to lighten. Throughout this process, he and I have become true partners. He is no longer a partner who just “helps out.”

This philosophy has shaped how Joe and I built our marriage and approach parenting. He dives deep into this in Episode 7 of his podcast Dadicated Joe, sharing how we’ve worked to keep the spark alive after becoming parents.

Applying these principles has not only brought more harmony to my family but also reinforced the importance of clear roles, mutual respect, and holistic well-being at Serenity Kids. We work to build culture and sustainable systems where everyone can truly thrive.

While encouragement is nice, what we all really need is a partner willing to jump in and fold the laundry when the piles get high. We’ve learned to be that support for each other. At home. At work. Everywhere.

5 Crucial Lessons

I’ve learned a wealth of actionable insights I’d offer to other romantic partners considering, or currently navigating, the high-stakes journey of entrepreneurial cofounding:

1. Strict Role Definition (and Unwavering Trust): This is nonnegotiable. You need to clearly delineate who owns what. Then, extend absolute trust in your partner’s domain. Undermining their decisions in their area of responsibility is a direct threat to both business progress and relationship integrity.
2. Cultivate Separate Spaces (Even Symbolic Ones): Joe and I quickly learned that constant physical proximity, transitioning from “work mode” to “couple mode” in the same room, was counterproductive. Whether it’s different offices or simply dedicated “zones,” creating some physical and mental separation during work hours is vital for psychological resets.
3. Proactive Relationship Investment: Your business will demand everything, but your personal relationship is the fundamental platform. Prioritize dedicated date nights, even if they’re modest. Engage in non-work conversations. Actively recall and reinforce the shared values and affection that initially drew you together, beyond the business ambition.
4. Embrace Dynamic Balance, Not Static Perfection: The concept of “perfect balance” is a myth. Some days, the business will command absolute priority. On others, your child will need every ounce of your attention. Success lies in embracing this inherent fluidity and adapting, rather than chasing an unattainable, rigid ideal.
5. Leverage Objective External Counsel: Engaging an objective third party—a business coach, a therapist specializing in entrepreneurial couples, or even a trusted mentor—provides invaluable perspective. They can facilitate healthy conflict resolution, reinforce boundaries, and ensure that communication remains robust and constructive.

The journey of building Serenity Kids has served as a rigorous masterclass in leadership, partnership, and parenthood for Joe and me. We’re not merely disrupting the baby food market; we’re actively demonstrating a new paradigm for how ambitious couples can build a thriving enterprise and a fulfilling family life. It’s not perfect. It’s often messy. But I hope our story encourages others to set strategic boundaries, show mutual respect, and find an abundance of resilience. Maybe those of us crazy enough to do both journeys together truly can have it all—even if it means putting your first “baby” to bed before focusing on bedtime at home.
