Send Katie a Text Message!!
If you want your interior design business to look different in 2027, you can't simply hope the market gets better.
You can't control interest rates, economic uncertainty, changing client behavior, or whether the perfect project lands in your inbox. But there is an enormous amount happening inside your business that you can control.
In this episode of Success by Design, we're bringing together all five pillars of The Design Business Diagnostic and looking at how to start positioning your company for a stronger, more profitable, and more...
132. Why More Services Won't Grow Your Interior Design Business | The Design Business Diagnostic, Part 6
Send Katie a Text Message!!
When the market slows down or clients start approaching projects differently, it's tempting to respond by adding more services, creating new packages, or changing your pricing.
But what if the problem isn't that you need more offerings? What if you need to rethink the ones you already have?
In this final pillar of The Design Business Diagnostic, I'm talking about Products & Offerings and why the right service mix isn't necessarily the one generating the most revenue or giving clients the most choices. It's the one that...
131. Why Your Interior Design Business Can't Grow Without You | The Design Business Diagnostic, Part 5
Send Katie a Text Message!!
At some point in the growth of an interior design firm, the problem is no longer your design talent, your clients, or even the number of people on your team.
Sometimes the constraint is sitting in the owner's chair.
In Part 5 of The Design Business Diagnostic, I'm diving into CEO Leadership and what it actually means to lead a growing design firm without becoming the bottleneck in every decision, project, and process.
There's a big difference between staying informed and staying involved...
130. Why Hiring More People Won’t Fix Your Interior Design Business | The Design Business Diagnostic, Part 4
Send Katie a Text Message!!
Being overwhelmed doesn't automatically mean your interior design firm needs another employee.
In Part 4 of The Design Business Diagnostic, I'm diving into Human Capital—and one of the biggest mistakes I see growing design firms make. Some owners are dramatically under-invested in people and have made themselves the bottleneck in practically every area of the company. Others have built expensive teams with overlapping responsibilities and still haven't created meaningful capacity.
Both situations can leave the owner exhausted. They require very different solutions. Pasted markdown

129. Why Your Interior Design Firm Keeps Running Out of Leads | The Design Business Diagnostic, Part 3
Send Katie a Text Message!!
If your interior design firm keeps running out of leads, your problem may have started months before your pipeline went quiet.
In Part 3 of The Design Business Diagnostic, I'm diving into the second pillar of a healthy design firm: Predictable Marketing. This isn't about posting more on Instagram, going viral, or chasing vanity metrics. It's about creating a repeatable system that consistently puts your firm in front of the right people and creates enough qualified opportunities that your business isn't riding on whether one or two...
128. Your Revenue Doesn't Tell Me If Your Design Business Is Healthy | The Design Business Diagnostic Part 2
Send Katie a Text Message!!
You can have a $500,000 interior design firm and be broke. You can have a million-dollar firm and still be broke. Revenue alone doesn't tell me whether I'm looking at a financially healthy company.
Welcome to Part 2 of The Design Business Diagnostic. Last week, I introduced the five areas I look at when diagnosing the health of an established design firm. Now we're going deeper, starting with Financial Foundation..
This isn't about becoming an accountant. It's about understanding enough about your numbers to financially lead your company and make d...
Ep. 127 The 5 Things That Actually Grow an Interior Design Business | The Design Business Diagnostic Part 1
Send Katie a Text Message!!
What if the thing you're trying to fix in your interior design business isn't actually the problem?
I've had designers tell me they need more clients when the real issue is profitability. I've had designers convinced they need another employee when their business doesn't have the systems, financial capacity, or leadership structure to support one. And I've seen designers try to fix their marketing when the offer underneath it isn't clear enough to market.
That's why I'm changing the way I coach—and why I'm introducing The De...
126. If I Wanted to 10X My Design Firm, Here’s Where I’d Start
Send Katie a Text Message!!
If I wanted to 10X the revenue of my interior design firm, I wouldn't start with marketing, higher prices, bigger projects, or another revenue stream. I'd start by asking whether the business I've built could actually handle ten times the work.
In this episode, I'm breaking down the six things I would focus on before aggressively growing revenue. We'll talk about designing the company you actually want to own, finding your highest-value work, fixing capacity before creating demand, removing the owner as the default decision-maker, understanding your real economics, and...
125. The Business Advice I’d Ignore If I Were Growing a Design Firm Today
Send Katie a Text Message!!
If your interior design firm is already making six figures, multiple six figures, or seven figures, the business advice that helped you get established may not be the advice that gets you to the next level.
In this episode, I'm breaking down what I would stop listening to if I were strategically growing an established design firm today. We're talking about why more revenue isn't always better revenue, why being busy isn't a hiring strategy, why more marketing won't fix weak positioning, and why a good opportunity can still take...
124. Before You Hire: What Your Interior Design Business Actually Needs
Send Katie a Text Message!!
If you're overwhelmed in your interior design business, hiring someone can feel like the obvious next step. But bringing another person into a business with unclear processes, weak financial visibility, or undefined responsibilities doesn't remove the chaos. It can actually create more of it.
In this episode, I'm breaking down how to know whether your design firm is truly ready to hire and why "I need help" isn't enough information to create a job description. We'll look at how to identify what's really consuming your time, determine whether you need...
123. When Your Successful Design Business Stops Feeling Successful
Send Katie a Text Message!!
What happens when you build the interior design business you spent years dreaming about—and realize you don't really enjoy running it anymore?
In this episode, I'm talking about a stage of business ownership that doesn't get nearly enough attention: when your business looks incredibly successful from the outside but no longer feels successful to you. You have the projects, revenue, team, and recognition you wanted, yet you're still carrying every major decision, checking email on vacation, and wondering why growth hasn't created the freedom you expected.
This do...
122. The Business Decisions I Wish More Interior Designers Made Sooner
Send Katie a Text Message!!
Some of the most important decisions you'll ever make in your business won't feel urgent.
There won't be a client demanding an answer or a deadline forcing your hand. Instead, they'll be the quiet leadership decisions that determine how resilient, profitable, and sustainable your business becomes over time.
In this episode, I share six strategic decisions every interior designer should make before they're absolutely necessary. We discuss reducing client concentration, protecting intellectual property, documenting institutional knowledge, strengthening your portfolio strategy, planning for continuity, and building a business that...
121. Overwhelmed Doesn't Mean It's Time to Hire
Send Katie a Text Message!!
Feeling overwhelmed is one of the most common experiences for growing interior design business owners. When projects begin piling up and every decision seems to depend on you, hiring can feel like the obvious next step. But what if overwhelm isn't actually telling you that you need another employee?
In this episode, I explore why hiring is often used to solve the wrong problem. We discuss how to identify whether you're facing a true capacity issue or whether your business is really asking for stronger systems, better processes, clearer boundaries...
120. The Client Email That Can Make Or Break Your Profit
Send Katie a Text Message!!
What happens after a client asks you to expand the scope of a project?
For many interior designers, this is where profitable projects begin to lose momentum. Without a clear process, additional work can quickly turn into unclear expectations, shrinking margins, and unnecessary stress. The way you respond in that moment says far more about your business than the email itself.
In this episode, I break down the one email I wish every interior designer would send when a client wants to add another room or phase to...
119. Why Small Interior Design Projects Might Be Your Biggest Opportunity
Send Katie a Text Message!!
Are you turning away small projects because they don't seem profitable enough?
You may be missing one of the biggest opportunities in your business.
In this episode, I challenge the common belief that designers should only pursue large, full-service projects. Instead, I explain why evaluating the client—not just the project—can lead to stronger relationships, more repeat business, and greater long-term profitability.
We also dive into customer lifetime value, profitable entry offers, scope management, and how to create a business that grows through relationships rather than...
118. Why Referral-Only Is Holding Your Business Back
Send Katie a Text Message!!
Referrals are one of the best compliments your business can receive—but they shouldn't be the only way you're attracting clients.
In this episode, Michelle Lynn and I unpack one of the biggest myths in the interior design industry: that being "referral only" is the ultimate sign of success. While referrals are an incredible source of business, relying on them alone creates an unpredictable pipeline and makes it difficult to confidently grow your firm.
We dive into what it actually takes to build a sustainable sales and marketing sys...
117. The Trade-Offs No One Talks About When Growing a Design Firm
Send Katie a Text Message!!
Growing your business should feel exciting—but if you've ever wondered why success suddenly feels heavier, this episode is for you.
One of the biggest misconceptions in the design industry is that growth automatically creates more freedom. In reality, growth often exposes the parts of your business that have been held together by your own talent, memory, and constant involvement.
In this episode, I'm talking about the hidden trade-offs of scaling a design firm, why so many business owners misdiagnose the problem, and the leadership shifts required to bu...
116. Booked Out, Busy, and Still Not Profitable Enough?
Send Katie a Text Message!!
Most interior designers think they have a revenue problem.
But what if the real issue isn't how much money is coming in?
What if it's how much money is quietly leaking out?
In this episode, Katie breaks down one of the biggest profitability challenges facing design firms today: hidden profit leaks.
From scope creep and revision loops to owner over-involvement and untracked labor, many designers are losing thousands of dollars without realizing it.
In this episode, you'll learn:
• Wh...
115. A Profitable Design Business Is Not the Same as a Scalable Design Firm
Send Katie a Text Message!!
One of the biggest misconceptions I see in the interior design industry is the belief that profitability automatically means your business is healthy.
It doesn't.
You can have beautiful projects, happy clients, strong revenue, and still be operating a business that can't handle another level of growth.
In this episode, I'm breaking down the difference between a profitable design business and a scalable design firm—and why that distinction matters if you're trying to move from six figures to se...
114. Your Business Doesn’t Need You As Much As You Think It Does
Send Katie a Text Message!!
What if the biggest thing holding your business back isn't your team, your workload, or your schedule?
What if it's the fact that your business still depends on you for everything?
In this episode, I'm diving into one of the biggest growth barriers I see in interior design firms: owner dependency. It's the moment many business owners reach where the business is growing, revenue is increasing, and the team is expanding—but somehow everything still comes back to them.
We're talking about the difference between delegation an...
113. The Art Of The Principle: The Hard Conversations No One Talks About That Will Save Your Business

In this special joint episode of Success by Design and Design for the Creative Mind, Michelle Lynne and I kick off a new series called The Art of Being the Principal. We dive into what it really takes to lead a successful interior design firm, move beyond being the operator of your business, and step fully into the role of CEO.
If you're balancing design work, team management, marketing, finances, and client demands while wondering why growth still feels so hard, this conversation is for you.

112. The Hidden Cost of Saying Yes to the Wrong Projects
Send Katie a Text Message!!
What if the project draining your energy, your time, your profit, and your team was never actually the problem? What if the bigger issue is that you said yes to it in the first place?
In this episode of Success by Design, I’m talking about the subtle “wrong projects” interior designers take on all the time — the ones that seem fine at first. The budget looks decent, the client seems nice enough, and the space has potential. But somewhere along the way, the project starts pulling your business in a direct...
111. The Decision That Will Either Grow or Stall Your Business This Year
Send Katie a Text Message!!
If you’ve ever finished a project and immediately moved on to the next one, this episode is going to hit a nerve—in the best way.
Because what if the thing keeping your business stuck isn’t your clients, your pricing, or your workload… but the fact that you’re not stopping to evaluate what actually happened?
In this episode, I’m breaking down the one decision that separates designers who stay stuck from those who scale—and it has nothing to do with doing more. It’s about how you’...
110. What I’d Fix First If I Took Over Your Interior Design Business Today
Send Katie a Text Message!!
In this episode, I’m walking you through exactly what I would fix first if I stepped into your interior design business and helped you scale to seven figures. And here’s the truth most people won’t tell you—you don’t need to work more, take on more clients, or post more content. What you actually need is to fix the right things in the right order.
If your business feels busy but not profitable, or like everything is urgent but nothing is truly moving the needle, this episode is...
109. Lessons from High Point Market: How Interior Designers Actually Attract Better Clients
Send Katie a Text Message!!
In this episode, I’m sharing a conversation I recently had with designers at High Point Market—and it’s one I couldn’t wait to bring to you here because it hits on something so many of you are experiencing right now.
If you’ve been saying “I need more clients,” but you’re not actively nurturing the relationships you already have, this might be the reframe you need. Because what I shared on that stage—and what I see every day in my coaching work—is that most designers don’t actu...
108. Scaling an Interior Design Business Takes More Than Bigger Goals
Send Katie a Text Message!!
In this episode, I’m unpacking something I see all the time in design businesses—and it might surprise you. It’s not that you need to think bigger. It’s that your business may not be built to support the growth you say you want.
I know how easy it is to believe the next level comes from bigger goals, more confidence, or finally stepping into your “CEO era.” But if your structure is weak, scaling doesn’t create freedom—it creates more chaos. More clients, more pressure, more decisions, and m...
107. The Smarter Way Interior Designers Increase Profit (Without More Clients or Higher Prices)
Send Katie a Text Message!!
In this episode, I’m joined by Heather McManus, founder of The Designers Collaborative, and we’re diving into a conversation that challenges what most designers believe about profitability. Because if you’ve been told the only way to make more money is to raise your rates or take on more clients, I want you to hear this—there’s another way. And it might completely shift how you think about your business.
IN THIS EPISODE:
Why making more money doesn’t always mean raising your pricesThe real reason...106. The Hiring Mistake Keeping Interior Designers Overworked
Send Katie a Text Message!!
If you’ve been feeling stretched thin and thinking, “I just need to hire another designer,” this episode might shift everything for you. I’m breaking down why hiring an assistant designer is often not the solution you think it is—and what’s actually keeping you overworked, overwhelmed, and stuck in your business.
IN THIS EPISODE:
Why hiring an assistant designer often doesn’t solve overwhelmThe difference between task support and true decision ownershipHow being the bottleneck is really what’s draining your timeThe most common hiring mistake I...105. Why You Don’t Have a Million-Dollar Interior Design Business Yet
Send Katie a Text Message!!
If you’ve ever thought, “I want more in my business, but I don’t know if I can handle more,” this episode is for you. Today I’m breaking down one of the biggest reasons interior designers struggle to scale—and it’s not your talent or your work ethic. It’s your business model. If your business is built on the assumption that you have unlimited energy and capacity, it will eventually hit a ceiling. In this episode, I walk you through what’s really keeping you from reaching that million-dollar mar...
104. Why Being Busy Isn’t Growing Your Interior Design Business
Send Katie a Text Message!!
If you feel busy all day but your interior design business still isn’t growing, this episode is going to hit home. I’m breaking down why constant hustle isn’t the problem—and why your business might actually be designed to keep you stuck.
IN THIS EPISODE:
I’m sharing what I see behind the scenes with so many interior designers: full calendars, constant work, and zero real growth. If you’re working nonstop but not seeing more profit, freedom, or scalability, it’s not a time issue—it’...
103. Why Your Interior Design Projects Keep Going Over Budget
Send Katie a Text Message!!
Have you ever wrapped up a project and thought… how did we get here again?
You started with a clear vision, a solid plan, and a client who seemed aligned. But somewhere between the mood board and install day, the budget unraveled. Now the client is stressed, you’re reworking the same design over and over, and a project that once felt exciting feels heavy.
In this episode, I’m breaking down the real reason interior design projects go over budget—and it’s probably not what you think.
...102. Why Interior Design Clients Keep Changing Their Minds (And How to Fix It)
Send Katie a Text Message!!
Have you ever had a client approve everything… only to start unraveling the design a few days later?
One change turns into five. The sofa shifts, then the rug feels off, then suddenly the entire room is back on the table. Your timeline gets pushed, your energy gets drained, and the project becomes far more complicated than it ever needed to be.
In this episode, I’m breaking down what’s really happening when clients keep changing their minds—and why it’s usually not about them being indecisive...
101. Scaling an Interior Design Business Beyond Referrals
Send Katie a Text Message!!
Referrals feel incredible as an interior designer. They’re proof your clients love your work and your reputation is strong. But there’s something most designers don’t realize—referrals alone are not a growth strategy.
In this episode, I’m talking about the quiet ceiling referral-driven businesses often hit. When your pipeline depends on referrals, your growth depends on someone else’s timing. That’s why so many designers experience the frustrating feast-or-famine cycle, even when their reputation is solid.
This conversation isn’t about abandoning referrals—they’re a wonderfu...
100. 100 Episodes Later: The Real Reason Interior Designers Feel Stuck
Send Katie a Text Message!!
After 100 episodes of Success by Design, there are a few patterns I simply can’t ignore anymore.
They’ve shown up in coaching calls, DMs, and quiet conversations after the mic turns off. And if you’re building an interior design firm right now — especially one you want to sustain you long-term — this episode is going to feel personal.
Here’s what I know for sure: your problem is not your design talent.
I have never sat across from a designer and thought the issue was creativity...
99. Why High Demand Doesn’t Mean You’re Ready to Scale Your Interior Design Business
Send Katie a Text Message!!
If you’re booked out, have steady inquiries, and your revenue looks solid — but you still feel capped — this episode is for you. High demand does not automatically mean you’re ready to scale your interior design business. If you can’t take on more without breaking something, it’s not a marketing problem. It’s a structural one.
In this episode, I’m breaking down why revenue growth and scalability are not the same thing. So many six-figure designers assume that because they’re busy, they’re ready to grow. But if everyth...
98. Signs You’ve Outgrown DIY Business Advice as an Interior Designer
Send Katie a Text Message!!
If you’re running a multiple six-figure interior design firm and finding that the business advice you used to love now feels surface-level, this episode is for you. DIY business advice isn’t bad. In fact, it’s incredibly helpful when you’re building momentum. But there comes a point when quick tips, Instagram soundbites, and six-week tactical courses stop moving the needle. If you’re still working too hard for the results you’re getting, it may not be an effort problem. It may be that your business has outgrown beginner-level strategy.
97. Why Raising Your Rates Didn’t Give You More Freedom (And What Actually Will)
Send Katie a Text Message!!
You raised your rates.
You updated your website.
You had the uncomfortable conversations.
And you thought, This is it. This is the turning point.
But you’re still working just as much. Maybe more.
If that’s you, this episode of Success by Design is going to hit home.
In this conversation, I break down why raising your interior design fees is often necessary — but never the magic fix everyone promises. Higher pricing doesn’t automatically create more freedom. In fact, wi...
96. Why Your Team Keeps Asking You the Same Questions (And How to Fix It as a Leader)
Send Katie a Text Message!!
If you’ve ever found yourself thinking, “I swear I’ve already answered this,” while a team member pings you yet again, this episode is for you.
Today, I’m unpacking one of the most exhausting leadership moments I see with designers — when your team keeps asking the same questions over and over, and it starts to make you wonder if you’re doing something wrong as a leader. I want to say this clearly right out of the gate: this isn’t a sign that you’re failing. It’s feedback. And when...
95. Why Your Interior Design Business Feels Heavier as It Grows (Even With More Revenue)
Send Katie a Text Message!!
If you’ve ever looked at your business and thought, “Why did this feel easier when I was making less money?”—this episode is for you.
Today, I’m talking directly to designers who are doing “everything right” on paper. The revenue is there. The team is there. The projects are bigger. And yet… everything feels heavier. More complex. More draining.
Here’s the truth I want you to hear upfront: you didn’t do anything wrong. This tension doesn’t show up because you failed—it shows up because you...
94. How to Choose the Right Coach for Your Interior Design Business
Send Katie a Text Message!!
Choosing a coach is a big decision—especially when your business is already successful, but something still feels heavy. In this episode, I’m pulling back the curtain on what coaching should (and shouldn’t) look like for interior designers. I share the mistakes I’ve made hiring coaches, the lessons I learned the hard way, and the exact criteria I use now—both when I hire support and when designers consider working with me. This isn’t about hype, Instagram followers, or quick fixes. It’s about clarity, alignment, and making decisions that...
