ABOUT THIS EPISODE
In this episode of Unconventional Wisdom About Conventional Wisdom, Kim Miller-Hershon sits down with Liz Mbwambo, founder of Upwynn Marketing, an agency built on a simple belief: established businesses deserve a marketing partner who truly understands what moves the needle. For most of her career, Liz worked on the vendor side of marketing, managing millions of dollars in annual media spend for brands ranging from national household names to local businesses. She saw firsthand how agencies make decisions, understood the incentives behind them, and recognized the gap between what clients were promised and what actually delivered results. After years entrusted with major marketing budgets, she left her six-figure career and bootstrapped her own agency from scratch, no investors, no safety net. A self-described hyper-planner (the one at the airport handing out the tickets), she opens the episode with the most out-of-character thing she's ever done: a last-minute trip to Spain where she planned absolutely nothing, and learned she doesn't have to be in control all the time.
In this conversation, Liz challenges the misconception that you have to have it all figured out before you start a business. She always pictured the movie version, the polished business plan, the whole outline, and when her husband told her to go quit (warning she'd keep moving the goalpost otherwise), she jumped without it all mapped out. She barely had a business name, and rebranded a year later. Kim adds the nuance that keeps it honest: you don't need everything figured out, but Liz did bring real marketing expertise, which lowered the bar. As Liz puts it, borrowing Dave Ramsey's image, she pulled the boat closer to the dock so that when she jumped, she wouldn't land in the water.
A rich, practical thread is who you surround yourself with, and what you share with whom. Liz's husband was the only person who knew her plan until the very end, not because her parents were naysayers but because she didn't want their protective fears (six figures, the health benefits her son depended on) to influence a decision that was really between her and her husband. She and Kim build it into genuinely useful advice: find mentors in different areas (the marriage you admire, the finances you want), look for people five years ahead of you, and if the people closest to you won't support your dreams, don't share them, talk about the weather instead and practice radical acceptance. Liz's reframe on the old "money makes you greedy" belief lands it: money magnifies what you already are, so a giving person with more money gives more.
Liz is refreshingly candid that the "she's got it all figured out" image is a myth, every single day. People she worked with doubted she'd make it, and now, nearly two years in with a team of nine after fast growth, she still puts her pants on the same way, gets fevers, and has days she just wants to be a couch potato. There's no magic potion CEOs drink in the morning. She spent the entire year on operations because they were messy, and told a new senior hire that every system sits at about 80% done, no bow on it, you'll take it the last 20% of the way. The deeper lesson she's had to mourn: the picture of handing things off her plate and finally coasting never arrives. As a founder, you're always being looped into the next phase, which is really a lesson in adjusting your expectations.
Her biggest leadership challenge is a live transition: she just hired a senior marketing manager so the team reports to him instead of coming straight to her, and she knows the adjustment (for them and for her) will take time as she steps back to work on the bigger picture. She and Kim bond over both building agentic AI workforces, Liz's CMO agent "Lizzie," Kim's "Moxie," both running on the Hermes platform, and Liz's tip to any founder: block off two days, build the agents, and your time will be far better suited long term.
Her most unconventional growth habit this year is deceptively simple: taking care of Liz. Year one was head-down, business-business-business; this year she added a workout routine, slow mornings (coffee, the dogs, the morning sun) that have shifted her mind considerably, and firm boundaries, closing the laptop at five and keeping her home office for work only, so work doesn't bleed across the kitchen table. On imposter syndrome, she's honest it hits all the time, fueled by a social-media algorithm full of marketers who seem to have it all figured out, and sharpened by the pressure women put on themselves to be excellent wife, mom, friend, and owner all at once. Her fix is to talk to herself in facts (you didn't get much time with your son today, but you had a real conversation in the car, and watched a movie yesterday, you're a good mom), because imposter syndrome is mostly comparison and lies. Kim adds Dan Sullivan's horizon metaphor, measuring yourself against where you were last quarter rather than an ever-receding ideal, and Liz closes on the one she gives her own friends: talk to yourself the way you'd talk to a friend.
This episode explores:
- Why you don't need it all figured out to start a business
- Pulling the boat closer to the dock before you jump
- Guarding who you share your dreams with, and radical acceptance
- Finding different mentors for different parts of your life
- Why money magnifies what you already are
- Why there's no magic potion, and every system is 80% done
- Mourning the picture of finally coasting, and adjusting expectations
- Transitioning the team to report to a new leader
- Building an AI workforce to free up a founder's time
- Taking care of yourself: slow mornings, workouts, and real boundaries
- Keeping work from bleeding into home
- Beating imposter syndrome by talking to yourself in facts
- Measuring against your past self, not an ever-moving horizon
- Talking to yourself the way you'd talk to a friend
Liz's perspective is a powerful reminder that readiness is a myth, that the support you surround yourself with matters as much as your expertise, and that building a business you can sustain means building a life you can sustain alongside it. Her journey from a six-figure corporate career to a fast-growing agency of nine shows that you can jump before you have it all figured out, as long as you pull the boat close to the dock first and keep talking to yourself in facts.
If you're a founder, marketer, or anyone standing at the edge of a leap, this conversation offers practical insight, honest talk about imposter syndrome and boundaries, and a refreshing case that you're far more ready than the voice in your head is telling you.
