When Kim Perell sold her company for $235 million, the headlines focused on the massive exit. What they didn’t capture were the wrong turns, missed opportunities and hard lessons that made that milestone possible. In her newest book, Mistakes That Made Me a Millionaire, Perell reframes failure not as a setback but as a catalyst for resilience, creativity and ultimately wealth.
A serial entrepreneur who has founded nine companies and an angel investor with more than 150 startups in her portfolio, Perell knows the road to success is rarely straight. Her journey, told in her three bestselling books, offers an inside look at what it really takes to build and rebuild businesses. The central lesson is that mistakes aren’t fatal, they are necessary.
The Power of Execution
Perell’s first book, The Execution Factor, tackles one of entrepreneurship’s most common challenge – ideas are everywhere but successful execution is rare. “Clarity of vision gives you power,” she told me. The challenge lies in turning ideas into action. Her advice is to “think big but act small.” Dream of seeing your product in every Target across America, for example, but start by selling it to a neighbor.
She also emphasizes the importance of finding even a single believer, whether a customer, an investor or a friend. That early validation gives entrepreneurs the confidence to keep going, especially when mistakes feel overwhelming. For Perell, execution is less about perfection than persistence. Progress comes from learning, adapting and continuing despite setbacks.
Jumping Into the Unknown
Her second book, JUMP: Dare to Do What Scares You in Business and Life, addresses another universal barrier – fear. Success, she argues, doesn’t come from staying safe. It comes from being willing to take the leap.
“Your confidence in yourself has to be greater than everyone else’s doubt,” she explained. Rejection, she says, is inevitable but it is also instructive. “Rejections are like mistakes. If it happens enough, you just get numb to it. I just know I have to get to the one yes so, I keep going.”
This perspective explains her willingness to invest at the idea stage, often before a company has revenue. She is betting on conviction, tenacity and self-belief, the very qualities that helped her recover after early career setbacks.
The Lessons of Mistakes
In Perell’s most recent book, Mistakes That Made Me a Millionaire, she shares the wrong turns that ultimately fueled her success. Among the most common mistakes she highlights are:
- Waiting until she felt 100 percent ready.
- Trying to do everything herself.
- Staying too long in the wrong role or relationship, and
- Picking the wrong partners.
One of her hardest lessons came from trying to shoulder everything alone. In her first company she adopted what she calls a “lone wolf” mentality. The result was burnout. “No matter how great you are, if you don’t have a team and you don’t have the ‘four people pillars’, like a house, you can’t stand.”
Those four pillars form a framework every founder can use:
- Support from at least one believer whether a friend, family member or colleague.
- A peer group of people on similar journeys.
- A mentor who can provide guidance and perspective.
- A team member or partner who can share the day-to-day work.
Without that scaffolding, she says, even the most determined entrepreneur will struggle.
Reframing Mistakes as Strategy
Perhaps the boldest message of her new book is that mistakes deserve a makeover. From childhood we are taught to avoid them at all costs. Perell insists they are not evidence of weakness but proof of progress. “Success isn’t a straight line,” she said. “It’s the mistakes and the challenges and roadblocks and no’s and rejections that make you great.”
She points to a defining moment early in her career when she turned down a board opportunity because she felt underqualified. Looking back, she calls it one of her biggest mistakes. Today she takes the opposite approach. “From now on I’m just going to say yes and figure it out as I go.”
By sharing the truth, not just the headline of a nine-figure sale, she reminds readers that every rejection, wrong partnership and missed chance is not the end but a step forward.
Advice Every Female Founder Should Hear
Perell’s advice is especially powerful for women who often feel pressure to be perfectly prepared before taking risks. She recommends women don’t wait until they are ready, don’t fear rejection and don’t go it alone. And, most importantly, don’t bury your mistakes.
“Mistakes are essential to being successful,” she said. “There is a lesson in every mistake. Learn from it and grow from it. Instead of trying to not make them, embrace them. Just don’t make the same mistake twice.”
