You start a business without quitting your job by using a systematic validation process that requires only 5-10 hours per week: validate your idea in week one, build a minimum viable product in week two, and test for paying customers in week three. The key is ruthless prioritization – focusing only on activities that generate revenue or prove demand, and using AI tools to compress months of work into hours. I’ve helped over 1,500 founders launch businesses this way, and many of them never quit their day jobs at all.
Did you know – New Founder School started as a side project. I never intended it to become a business. I was taking a break between startups, coaching a few founders on the side, and it grew into a company doing hundreds of thousands in revenue – all while I maintained other commitments.
The “quit your job to pursue your dreams” narrative is romantic. It’s also terrible advice for most people.
The entrepreneurs who tell you to “burn the boats” usually had a safety net you don’t see. Family money. A spouse’s income. Savings from a previous exit. Six months of runway from a severance package. Deep roots in the location.
When I burned out from my venture-backed AI startup in Silicon Valley, I didn’t have that cushion. I had to figure out how to build something sustainable without the luxury of full-time focus.
What I discovered fundamentally shifted what I believed about entrepreneurship.
The constraint of limited time didn’t slow me down. It forced me to eliminate everything that wasn’t essential. And it turns out, 80% of what we call “entrepreneurship” is actually just busywork disguised as progress.
Here’s the framework I teach founders who want to build while employed:
Hours 1-2: Weekly Strategic Planning
Every week starts with one question: “What is the ONE thing that would move this business forward most?” Not five things. One thing.
Most employed founders fail because they scatter their limited hours across too many activities. They’re “working on” the business without making actual progress. Strategic focus is your unfair advantage when time is scarce.
Hours 3-6: Building or Selling (Never Both in Same Week)
Here’s the counterintuitive truth: you should alternate weeks between building and selling, not try to do both simultaneously.
Week 1: Validate the idea (customer conversations, market research) Week 2: Build the MVP (using AI tools to compress development time) Week 3: Sell (get paying customers or clear rejection) Week 4: Iterate based on feedback
This rhythm prevents the common trap of endless building without validation, or constant selling of something that doesn’t exist yet.
Hours 7-10: Leveraged Activities Only
The remaining hours go exclusively to activities that create leverage: content that sells while you sleep, systems that automate repetitive tasks, or relationships that open multiple doors.
If an activity doesn’t compound over time, it doesn’t deserve your limited hours.
Everything I just described became 10x more powerful when AI tools matured.
What used to take months now takes hours:
Market Research: Two months of competitive analysis, customer interviews, and trend research? Now 2-3 hours with the right AI prompts. I’ve watched founders validate entire market opportunities in a single evening after work.
MVP Development: The “I need to learn to code” or “I need to hire a developer” barrier? Gone. With “vibe coding” – describing what you want to AI tools instead of writing code – non-technical founders build functional prototypes in a single weekend.
Content Creation: Your entire marketing stack – website copy, email sequences, social content – can be drafted in an afternoon. Not polished perfection, but good enough to test whether your messaging resonates.
Customer Service: AI chatbots handle the repetitive questions from day one, so your limited hours go to conversations that actually close deals.
This isn’t about AI replacing the work. It’s about AI compressing the timeline so that 5-10 hours per week actually produces results.
The biggest mistake employed founders make: spending their precious weekend hours building something nobody will pay for.
Before you write a line of code or create a single piece of content, answer these questions:
Question 1: Will someone pay for this?
Not “do people say it’s a good idea.” Will they actually hand over money? The only valid answer comes from attempting to sell it before it’s built.
I teach founders to pre-sell: describe the solution, set a price, and ask for payment. If five people won’t pay $100 for something that doesn’t exist yet, fifty people won’t pay once you build it.
Question 2: Can I reach these customers without paid advertising?
When you’re building on the side, you don’t have budget for customer acquisition. You need organic channels: content that attracts, communities where your customers gather, or a network that spreads the word.
If you can’t describe exactly how your first 10 customers will find you without spending money, go back to the drawing board.
Question 3: Can I deliver this without quitting my job?
Some business models require full-time attention. Service businesses with demanding clients. Products that need constant iteration. Anything with same-day expectations.
Other models thrive on part-time attention. Digital products. Productized services with clear boundaries. Content businesses. Software that runs itself.
Choose the model that fits your constraints, not the model that sounds impressive.
I run two businesses – New Founder School and Shaanti – while teaching at San Francisco State University and raising my 17-month-old. I work Monday through Wednesday on execution, and reserve Thursday through Friday for strategy.
This isn’t a productivity hack. It’s a fundamental redesign of how business can work.
The founders working 70-hour weeks aren’t outperforming the founders working 30 hours. They’re just doing more of what doesn’t matter.
The constraint of a 3-day week forced me to eliminate every activity that wasn’t directly tied to learning, building, or selling. And our revenue grew 50% year-over-year while I worked less.
The same principle applies when you’re starting on the side. Your 5-10 hours per week isn’t a limitation – it’s a filter that eliminates busywork.
Many of the most successful founders I work with never quit their jobs.
They built businesses that generate $50,000, $100,000, even $200,000 per year in additional income – while keeping the stability of employment. For them, the side business isn’t a stepping stone to full-time entrepreneurship. It IS the goal.
The “quit your job” narrative assumes everyone wants the same thing: rapid growth, venture scale, all-consuming focus. But what if you want something different?
What if you want additional income without additional risk? What if you want creative fulfillment without financial pressure? What if you want optionality without burning bridges?
That’s a valid path. Maybe the better path for most people.
But if you DO want to transition to full-time entrepreneurship, here’s the milestone that matters:
Your side business should replace 50% of your salary before you quit.
Not 100%. 50%.
At 50% replacement, you have proof of concept, established revenue, and enough runway to grow to full replacement while living on savings. You’ve de-risked the leap substantially.
Most importantly, you’ve built a business that works – not a business that requires your full-time attention to function.
Everything I’ve described – validation, MVP building, customer acquisition – used to require months of learning and trial and error.
Not anymore.
On January 31st, I’m hosting the New Founder School AI Hackathon with Fractal. In a single day, you’ll go from idea to working AI-powered app, ready for deployment to ChatGPT’s App Store.
This is specifically designed for people who can’t quit their jobs to “figure out” entrepreneurship. One Friday. 8 hours. You walk out with proof that you can build.
Here’s what happens:
Morning (10am-1pm): The AI-Powered Idea Incubator framework. You’ll validate your idea and build your MVP using “vibe coding” with Anshul and me – no technical skills required. Describe what you want, and AI builds it.
Afternoon (1:30pm-4pm): Fractal MCP teaches you to deploy your app to OpenAI’s ChatGPT Store, instantly accessible to 800M+ weekly users.
By 5pm: You have a working product. Not a plan. Not a pitch deck. A functional app that people can use.
One day of your weekend. $20 in-person, $10 virtual. That’s it.
You can make meaningful progress with 5-10 focused hours per week – but the key word is “focused.” Five hours of strategic work beats 20 hours of scattered activity. Use AI tools to compress research, building, and content creation. Protect your hours ruthlessly, and spend them only on validation, building, or selling.
Check your employment contract first – some have non-compete or moonlighting clauses. Generally, if your side business doesn’t compete with your employer and you’re doing it on personal time with personal resources, you’re fine. Many employers actually appreciate entrepreneurial employees. But if you’re in a sensitive role or competitive industry, consult an employment attorney before going public.
Businesses with asynchronous delivery work best: digital products, productized services with clear scope, content businesses, software tools, and courses. Avoid businesses requiring real-time availability during work hours, client emergencies, or constant iteration. The best side business is one where you can batch work on evenings and weekends without customers noticing.
The brutal truth: if you can’t find 5-10 hours per week, you either don’t want it enough or your life needs restructuring before you add entrepreneurship. Most people waste more than 10 hours weekly on activities they wouldn’t choose if they were intentional. Audit your time for one week. The hours exist – they’re just hiding in Netflix, social media scrolling, and activities you do on autopilot.
When your side business consistently generates 50% of your salary for at least 3-6 months. This proves sustainable demand, gives you runway to grow, and demonstrates the business works without your full-time attention. Quitting before this milestone is gambling. After it, you’re making a calculated transition with evidence on your side.
Yes – and this is the biggest shift in the last two years. AI tools now let you build functional software by describing what you want in plain English. I’ve watched founders with zero coding experience deploy working apps in a single day. The barrier isn’t technical ability anymore – it’s clarity about what you want to build and for whom.
Don’t do it. Non-compete violations can result in lawsuits, career damage, and destruction of your side business. If your best idea competes with your employer, either wait until you leave, pivot the idea to a non-competing market, or find a new job first. There are infinite opportunities that don’t put your livelihood at risk.
Compartmentalization is essential. When you’re at your job, be fully at your job. When you’re building, be fully building. The mental drain comes from constant context-switching, not from the workload itself. Designate specific times for business work – Saturday mornings, Tuesday evenings – and protect those blocks. Use your job hours to perform well at work, not to stress about your side project.
Here’s what I want you to walk away with:
You don’t need to quit your job to start a business. You don’t need to learn to code to build technology. You don’t need months of preparation to validate an idea. You don’t need permission from anyone to begin.
The stories we’ve been told about entrepreneurship – the dropout in a garage, the all-in leap of faith, the years of struggle before success – those are the dramatic stories. They’re not the only stories.
Most successful businesses I’ve seen started quietly. On the side. In the margins of someone’s already-full life. They grew because the founder was methodical, not because they were reckless.
You can be one of those founders.
