Key takeaways:
- You need 5-8 hours a week, not 40: A coaching or consulting business is the fastest business model to build in the pockets of time you already have around a full-time job, using an hour at lunch, an hour after work, and weekends.
- Use the Tetris Framework to make your limited hours count: Figure out where and when you’re the most productive and only focus on sales-driving tasks to build your business on the side, just like you fit Tetris blocks to win the game.
- Follow the 3-2-1 Rule before you quit: You need 3 months of consistent sales, 2x your salary saved, and/or 1 year of living expenses to quit your job.
- Your job is an advantage: Its built-in routine makes it easier to slot business tasks into your schedule than to self-manage an unstructured day.
Most people think starting a business while working full-time requires 40-hour weeks and constant hustle. The truth is: You can get one off the ground in 5 to 8 hours a week. Here’s how.
If you dream of building your own business but feel stuck in a demanding 9-5, you’re not alone. In this guide, I’ll show you exactly how I launched a 6-figure business while working full-time—and how you can use my lessons to start your own business.
You’ll learn:
- The business model that lets you grow without burning out
- How to find your unique idea (even if you’re good at a lot of things)
- How to land your first paying clients
In this guide, I help you find the hours to build a business around a full-time job. If you’re still deciding whether and when to make the leap, I cover that in full in How to Escape the 9-5 Grind. Read that one first if you aren’t sure you’re ready yet.
Can you have a side business while working full-time?
Yes, you can build a business on the side, even with a full-time job. The right business model lets you build your business in about an hour a day.
And because your salary funds the business, starting one while you work full-time is actually the smart thing to do.
You’re not alone in starting your business part-time.
The number of entrepreneurs starting their business as a side hustle — while still holding a full-time job — is growing fast. According to Entrepreneur, it jumped from 27% in 2022 to 44% in 2023, and a quarter of all entrepreneurs today start out working a full-time day job.
So no, you don’t need to quit first. I didn’t – I just found the time to do it.
When I started my business, I was managing a team at a fast-growing tech startup with packed days and endless meetings.
By using 30-45 minutes at lunch, an hour after work most nights, and weekends, I was able to get my first clients and scale my coaching business to $106,000 in four months.
Then I quit my job.
Can YOU start a business while working full-time?
Building a successful business while working full-time isn’t up to luck or other external factors. It comes down to you.
Yes, you’re busy.
Yes, it feels scary.
But we’re talking about a business that lets you work from anywhere, spend more time with your family, make more money, and be happier and healthier than you are in your 9-5. All of this while helping people do something that has a huge impact on their lives.
To see just how possible it is, take a look at my quick video here:
Is it legal to start a business while employed?
Yes, in most cases, but check your employment contract for non-compete or non-solicitation clauses first, especially if your side business could compete for the same clients as your employer. I walk through exactly how I navigated this with my own employer, including why it never became a conflict of interest, in How to Escape the 9-5 Grind. (I’m not a lawyer — treat this as a starting point, not legal advice.)
Now for the fun part:
1. What’s the best business idea for a busy full-time employee?
With only 5-8 hours a week to work with, the best business idea is one that sells you — your experience, knowledge, and judgment — rather than a product you have to build first.
Coaching and consulting let you generate income before you’ve built anything, because the “product” already exists: it’s what you already know.
If you’re a risk-averse person like me, you want a business that will safely let you quit your job, not one that requires all your time and money for two years before you even know if it will work. Something I share in this quick video:
With online coaching, clients are fundamentally purchasing your expertise. Unlike physical or digital products, you don’t need to spend months creating the product or building inventory, managing supply chains, or filming lessons before you can make your first dollar.
Package your corporate or lived experience into a $1,500–$2,000 premium offer, and you only need to sign one or two clients to generate real, life-changing side income.
Coaching also makes it easier to deliver results fast, because one-on-one work gets your client a quicker win, which means faster testimonials and faster word-of-mouth — both of which do the marketing work for you.
I started monetizing my own job skills, helping other entrepreneurs run Facebook ads. But your skill can be something else entirely. My clients have built businesses in 50 different niches ranging from health to mindset and parenting coaching.
I go deep on how to turn a skill into a validated, sellable niche — including the “fun signal” method and the 3-filter test I use with my own students — in my guide on how to find a coaching niche.
For now, the quickest starting point is this: write down a short list of skills you have, then check if people are already paying for a service like it. If they are, that’s proof there’s a market.
Having an idea is one thing. Setting up your business is another — I’ll cover that next.
2. How do you set up a business while working full-time?
Setting up a business while working full-time is simple if you don’t overthink this part.
You need to choose a business structure, check whether your niche requires a certification, and create a client contract. That’s it.
Step 1: Choose your business structure
Choose between operating as a sole proprietorship or a limited liability company (LLC). A sole proprietorship is easier. There’s very little paperwork involved. LLCs come with tax benefits and legal protection.
The best option? Start with a sole proprietorship and then start an LLC once you land your first clients.
Step 2: Check if you need a certification
Most coaching and consulting niches don’t require one. But some, mainly health coaching niches, have stricter requirements, so check your local state rules before you get started.
Step 3: Create a contract
The last thing you need is a contract you can send to clients to start working with them. Read more in this blog post on creating your own coaching contract.
Notice how none of this requires you to build a website or create social profiles. All that comes later. For now, the focus is on getting your first client.
So the real question is what you do with your business once it’s set up. That’s what I’ll cover next.
3. How do you have time for your business on the side of your 9-5? (The Tetris Framework)
You don’t find more time for your business while working full-time — you fit your business into the time you already have, the way pieces fit into Tetris. In Tetris, you never get to choose the shape of the next piece or clear the whole board at once. You just place what you’re given as precisely as possible, one piece at a time, so nothing gets wasted.
Building a business around a full-time job works the same way: you can’t control how much time you have, only how well each block of it is used.
When I started my business, I had an extremely demanding job as a manager at a tech startup. I didn’t have hours to spend on my side business — just 30 minutes to an hour a day (during lunch breaks and after work), plus weekends.
The reason this works isn’t that I found extra time. It’s that I stopped treating each block of time the same way, and started fitting the right task into each one — just like a Tetris piece only works if it goes in the right slot. Here’s what that actually looks like.
1) Workspace anchoring
Your brain doesn’t switch into focus mode instantly. It needs a cue.
So give it one.
Pick one physical spot (a specific desk, a corner of your kitchen table, or a chair in another room) and use it only for business work. Nothing else happens there.
Put your phone in a different room entirely.
Do this consistently, and your brain starts associating that spot with focus. Even if you only have 20 minutes, sitting down in your anchor spot gets you into deep work far faster than trying to focus wherever you happen to be. For example, in the early days, my own anchor spot was my gray, comfy couch.
That’s your first Tetris piece.
2) Energy-flow scheduling
Most time-management advice assumes every hour of your day is equal. It isn’t, and fighting your own energy is one of the fastest ways to waste your time.
In Tetris, a piece that’s technically “available” still doesn’t help you if you force it into the wrong gap. Your time works the same way: an hour on your calendar isn’t automatically a usable hour if your brain is fried.
I’m a night owl. I tried waking up at 4 AM to “get ahead” on my business before work, like every productivity guru recommends. It made me exhausted and useless for the rest of the day.
So I flipped it. I scheduled the heavy mental lifting, like content ideation, writing sales copy, anything that required real thinking, for weekends, when my energy was highest.
On weekday evenings, when I was running on fumes after work, I stuck to low-energy tasks: posting pre-written content, answering emails, and light admin.
3) No room for productive procrastination
Your brain wastes almost all of your time if you let it.
Give someone a free Saturday to work on their business, and they’ll spend three hours tweaking their logo, coding a popup, or building an email automation, when they haven’t landed a single client.
It feels productive, but it isn’t.
Give that same person 20 minutes, and something different happens — they’re forced to skip the busywork and go straight to the two things that actually move a business forward: having a conversation, or helping someone.
That’s the real gift of a Tetris-style schedule: when every piece has to go somewhere useful immediately, there’s no room left for unproductive work.
The only thing you should focus on at this point are tasks that help you get your first client. Not sure what they are? In my guide on how to get coaching clients, I break down the only tasks you need to focus on right now.
If you’re still unsure if you have the time, take a look at my video here where I break down even more actionable tips to stop wasting your time after hours:
4. What does it cost to start a business on the side?
It costs as little as $0 to start — you can land your first client using only skills you already have.
But there are three cost levels as you grow, and knowing them upfront helps you avoid the most expensive mistake: spending out of fear instead of strategy.
Coaching and consulting are ideal side businesses because they need almost no upfront investment. You’re the product, so your biggest cost isn’t inventory or a lease — it’s your time.
I signed my first $5,000 client with zero investment. That’s Level 1: scrappy and determined.
After that, you’ll likely move to Level 2, where you reinvest your salary into things that buy back time — a business coach, learning to write and show up on video, and basic legal and admin setup. It won’t all pay for itself immediately, and that’s fine while your paycheck covers the bills.
Level 3 comes once your business has legs: reinvesting profits into better systems, sales coaching, and paid traffic to scale what’s already working.
The real danger isn’t spending too little — it’s spending out of fear. Buying expensive help before you understand your own market rarely pays off, and it’s the single costliest mistake new entrepreneurs make.
My rule: never risk your financial stability, and never invest your last dollar to “prove” you believe in yourself. Your job is what makes it safe to invest at all.
Next: setting goals and building the right mindset.
5. How do you set goals for your side business?
Set “rubber band” goals — targets that stretch you but still feel believable, like landing one paying client, rather than hitting $30,000 in your first month.
And measure yourself on what you control (leading metrics like pitches sent), not what you don’t (lagging metrics like sales closed).
Goals are crucial to starting a business while working because they help you gauge your growth and offer clarity.
The kind of goal you set — short-term or long-term — doesn’t matter. What matters is whether it’s a rubber band goal: a stretch, not a dream. Aim too big (“$100,000 in six months” with zero track record) and your brain knows it’s unrealistic before you even start.
Instead, pick something that makes you a little nervous but still believable: finding your niche, landing your first client, or hitting your first $1,000 month. Each small win builds the belief you need to repeat it.
But not all goals are equal. A goal like “get 10 sales” depends on other people saying yes — that’s a lagging metric, and chasing it breeds anxiety. A goal like “pitch 20 people this week” depends only on you — that’s a leading metric, and it’s entirely within your control. Build your goals around actions you can control, and the results tend to follow.
Once you have your goal, work backward: what’s the one thing you need to focus on this month to hit it? Ignore everything else — that’s how you avoid the busywork that quietly eats your limited hours.
6. How do you overcome the self-doubt of building your business?
You overcome self-doubt with four mindset shifts: embracing a beginner’s mindset, getting comfortable with failure, getting comfortable with selling, and reframing your limited time as a structural advantage rather than a disadvantage.
Strategy and tactics only work if you believe your business will succeed.
Shift #1: Embrace a beginner’s mindset
Right now, you’re starting from scratch. And you need to learn a bunch of new skills, like selling, content creation, and more.
So it’s essential to shift your thinking from “Why aren’t people buying from me?” to “I get it. I’m earning my stripes.”
When I started my first coaching business, I knew I had a lot to learn about copywriting, marketing, and creating videos. I focused on learning from many people who are great at what they do in different industries. At all times, I asked myself, “How did I do this time? What else can I do?”
Shift #2: Embrace failure
Yes, failure sucks. But you need to get good at embracing it to succeed.
A few failures shouldn’t get you thinking, “Maybe I’m not cut out to be an entrepreneur.” There are SO many things you do in your business that will fail. It’s just part of the process.
Ask yourself what you can learn from those failures instead of wallowing or giving up.
Shift #3: Get comfortable with selling
There’s nothing scammy about selling. It’s about exchanging value. You offer something in exchange for money.
And trust me — if your clients want it, they’ll buy it! If not, it wasn’t for them. They can make their own decisions.
Shift #4: See your limited time as an advantage, not a limitation
A lot of people think: “I’ll really commit once I quit my job.” In reality, the opposite is usually true.
A full-time job comes with a built-in structure — you wake up at the same time, commute at the same time, and have a hard stop at the end of the day. It’s far easier to slot business tasks into an existing routine than to self-manage a completely open, unstructured day from nothing.
Give someone 12 free hours with no framework, and most people don’t get more done. They get less done because they have to make new decisions all day long.
If you don’t yet have the discipline to work on your business in the small pockets of time you have now, an empty calendar won’t hand it to you either.
7. How do you overcome the fear of starting a business?
You overcome the fear of starting a business by expecting to fail — and starting anyway. Reading more won’t cure it; only action does.
Rejection doesn’t stop once you’re successful, either, it just stops mattering as much.
You might feel you have nothing to offer, or you’re afraid of what people will say if you put yourself out there.
Look: it’s scary to start a business. In fact, it’s probably one of the most challenging things you’ll ever do in your life.
You can go on to read hundreds of blog posts on this topic, but I guarantee that it won’t cure your fear. What will help you get over it is to get started. The sooner you start, the sooner you get to a point where you can finally quit your job.
Here’s the thing: you will “fail” in one way or another. You might “fail” at finding the right business idea the first time. Or you might get rejected. Or you could be so afraid of putting yourself out there that it takes months to get started.
Trust me — putting yourself out there for the first time will feel like the scariest thing you’ve ever done.
Even today, I get rejected — like this podcast pitch. And at this point, I’ve been featured on sites like Forbes and Business Insider, and my business makes multiple 7-figures. It’s just part of being an entrepreneur and putting yourself out there.
But you’ll never succeed if you don’t overcome those first failures. So address your fear by expecting to fail.
When should you quit your full-time job?
Quit only once you’ve hit the 3-2-1 Rule:
- 3: At least three months of consistent business sales
- 2: At least double your current salary saved, to cover lost benefits and unexpected costs, and/or
- 1: A safety net of at least one year’s living expenses
I know you’re itching to quit your job. I remember telling myself every week, “Next week, I’ll turn in my notice.”
But whatever you do, don’t quit right away. You shouldn’t leave your job before you know your business will keep paying your bills once your salary disappears.
If you focus on a few tasks every day, it doesn’t have to take years — that’s the beauty of a coaching or consulting business. You only need a handful of clients.
The key to scaling a business while working: be good at your job and your business, without letting either bleed into the other.
Compartmentalize — business time and work time stay separate. That also means being intentional with your free time; weekends go toward learning and working with clients, not just unwinding.
Following these steps prepares you for the ups and downs of entrepreneurship — and there are plenty of benefits to starting a business while working, too. I’ll cover those next.
What are the benefits of starting a business while working full-time?
The biggest benefits are lower financial risk, guaranteed income while you test your idea, and access to benefits like healthcare and retirement that you’d otherwise have to pay for yourself.
Your job is what makes it possible for you to build your business.
There are plenty of perks to starting a business while working:
- A guaranteed income: You’ll still have a steady income from your full-time job, so there’s not much financial risk involved. Any extra cash can be used to invest in your business.
- You still have benefits: A full-time job offers valuable perks like paid time off, healthcare, and retirement planning. You’ll have to pay for those out of pocket once you quit.
- You can test your idea and adjust it when necessary: Starting a business while working gives you the flexibility to test and refine your idea without the pressure to succeed instantly.
- You can take more risks: A steady paycheck gives you room to experiment with what works for your business, without every decision carrying financial life-or-death stakes.
- You learn to work with less time: Building a business alongside a job forces you to prioritize ruthlessly and maximize efficiency — a skill that pays off long after you’ve gone full-time.
- Networking opportunities: Your colleagues can offer valuable insights and potentially become your future customers.
Ultimately, starting a business while working gives you a safe, low-risk way of leaving your job — without having to stress about finances or whether your business idea will actually work.
So, how possible is it really to build your business? Take it from these successful entrepreneurs:
What are real examples of businesses people started while working full-time?
I’ve helped people in nearly every industry build profitable businesses on the side of a full-time job, from health coaching to real estate consulting to online course creation.
Below are real client examples across different niches, so you can see what’s actually possible.
Johanna: From exhausted new mom to health coach
Johanna was working a demanding corporate job while raising newborn twins. A year postpartum, she was still struggling to lose the weight and felt nothing like herself.
Instead of hours at the gym she didn’t have, she researched and built her own custom nutrition system using specific herbs and spices — and lost 10 pounds in her first month.
That result became her offer. She started coaching other busy, overwhelmed moms using the exact system that worked on her, and has since helped clients lose up to 50 pounds in eight months, all while working her corporate job on the side.
Ryan: From 9-5 employee to real estate consultant
Ryan worked a standard 9-5 while buying and renting out rental properties on the side. Over time, he developed his own real estate investment strategy, and realized other investors would pay to learn it.
The problem: He didn’t have time to build an audience from scratch. Instead, he pitched himself as a guest on established real estate podcasts and wrote for industry blogs that already had the audience he wanted. Listeners trusted his expertise because he’d demonstrated it on platforms they already followed — and they came to his site asking to hire him.
Jasmine: From corporate animator to $30–50K/month course creator
Jasmine was a highly paid animator with credits on major films, a demanding schedule, and two young kids. She was too risk-averse to quit her stable job.
Rather than trying to build everything at once, she focused on building different parts: First, her offer, a course (packaging her technical animation skills into a curriculum for aspiring animators), then the sales system.
Once she had a proven product, she built a fully automated funnel — webinar, landing page, and email sequence — so her limited weekday hours went entirely toward driving traffic. Her course quickly started generating $30,000 to $50,000 a month.
You can start a business in just a few hours a week
As you’ve seen, it IS possible to start a business while working a full-time job.
What you need to do is stay focused and follow a few simple strategies.
The payoff is worth it:
A business that lets you have the freedom and flexibility you want and that has a real impact.
And no, you don’t need more time, more money, or a better idea than the one you already have. You just need a plan.

Thanks Luisa, great inspirational points. I have been feeling overwhelmed with the process of starting while keeping a full time job. This has lifted my spirits.
There is definitely a LOT to it! But it’s absolutely doable. Glad to hear this helped. 🙂
A six figure business is possible if you know how you will automate and outsource your processes. This will help you have a business while having a 9 to 5 job.
Worth reading this article. Now, i will try to find time slots when i can really do something great for business with my full time job. My actual problem is the commuting time to office which is a bout 3 hours a day.
