Solving a problem nobody urgently has
The idea is clever, but when you ask real people, they shrug — the problem exists, but it isn't painful enough for them to change their behaviour or pay for a fix.
Entrepreneurship · The Founder's PlaybookHow to build a startup?
You don't need a perfect plan, funding, or a world-changing idea to start. You need to look honestly at what you already have, take one small real action this week, and let real people — not a business plan — tell you what to build next. This page is my own attempt to say that plainly, drawn from the effectuation research I study and teach.
Before you write a business plan
A business plan predicts a future you can't yet see. A first customer is a fact.
What is the smallest, realest thing you could do this week to learn if anyone actually wants this?
If you had to start with only what's in your bag right now, what would you build?
01 / Start where you are
Most founders don't start with a plan. They start with a means.
Research on how experienced entrepreneurs actually think — a field called effectuation — found something counter-intuitive: they rarely start by predicting a market and working backward to a plan. They start by looking at who they are, what they know and who they know, and asking what they could create right now with just that. The five ideas below are that logic, explained without jargon.
02 / Five moves in the playbook
What separates builders from planners.
Switch between the five below. Each has a plain-English explanation, what it looks like in a real (if illustrative) example, and one small thing to try this week.
Start with what you have, not a grand vision
Don't wait for the perfect idea or a business plan that predicts five years of revenue. Look at what you already have — your skills, your network, a few thousand rupees, a weekend — and ask what you could build with exactly that, starting today.
What this looks like
A student who is good at editing video and has three friends running small Instagram shops doesn't need funding to start. They already have a means: offer to edit reels for those three shops this week and see what happens.
Try this
List three things you already have (a skill, a relationship, a small amount of money, spare time) and one thing you could build with just those three things by Friday.
03 / Before you build anything
Talk to five real people before you write one line of code.
Not a survey — a conversation. The goal isn't to pitch your idea and hope for encouragement. It's to understand their life well enough that your idea becomes obvious, or falls apart, before you've spent a rupee building it.
1
Find the right five
People who actually have the problem today, not people who might one day.
2
Ask about today, not tomorrow
What do they currently do about it? Don't ask if they'd use your idea — ask what they already do.
3
Listen for money and workarounds
Anything they already pay for or have hacked together is the strongest signal of real pain.
4
Resist pitching
If you spend the conversation explaining your idea instead of listening, you learned nothing.
04 / What an MVP actually is
Not a smaller product. An answer to your biggest doubt.
A minimum viable product isn't a stripped-down app. It's the smallest, fastest thing you can build or fake to answer the one question that would kill your idea if the answer were no. Often that means doing the work by hand before you automate any of it.
What people often build first
A polished app, website or brand
Weeks of work go into something that looks professional before a single stranger has used it — and the riskiest assumption in the whole idea is still untested.
What actually answers the question
A phone number, a spreadsheet, and you doing the work by hand
Take five real orders manually, deliver them yourself, and see if anyone pays a second time. That single fact is worth more than a finished app nobody has opened.
05 / Numbers to know early
You don't need a finance degree. You need four numbers.
These won't make or break your idea by themselves, but not knowing them is how founders run out of money while still feeling optimistic.
- Burn rate
- How much cash the business spends, net of any revenue, in a typical month.
- Runway
- Cash in hand ÷ monthly burn rate — how many months you can operate before running out.
- Unit economics
- Whether you make or lose money on one customer or one order, before accounting for fixed costs.
- Retention
- The share of customers who are still using or buying from you after a fixed period — the honest test of whether you've built something people actually want.
Want the fuller toolkit? The Guesstimates and Case Frameworks pages walk through how to build numbers like these from scratch.
06 / How early startups actually die
Not usually one big mistake. Six small, avoidable ones.
Running out of cash before running out of ideas
Founders often die with unexplored options still on the table, simply because they spent too fast and didn't know their runway in months, not rupees.
Building in isolation for too long
Months are spent perfecting a product before a single real customer has seen it — by launch, assumptions that were never tested have hardened into the whole design.
Ignoring how customers will actually find you
A genuinely useful product with no realistic path to reach its first hundred customers is not yet a business — distribution is a design decision, not an afterthought.
Co-founder conflict left unaddressed
Disagreements about equity, roles or commitment level are avoided early to preserve the friendship, then resurface later at a much higher cost.
Scaling before the core loop actually works
Hiring, marketing spend and new features are added to a business that hasn't yet proven a small group of customers will use and pay for it repeatedly.
07 / Founder myths, busted
The five sentences that stop students before they start.
The myth
"I need a completely original idea."
The reality
Almost every successful business is an old idea done for a specific group of people better than anyone currently does it. A tiffin service, a tutoring app, a laundry pickup — the idea rarely wins. Knowing exactly who you serve and why they'd switch to you does.
The myth
"I need funding before I can start."
The reality
Funding buys you speed, not permission. Almost anything can be tested at a tiny scale first — by hand, on WhatsApp, with your own time — before a single rupee of outside money is involved.
The myth
"I need to know how to code."
The reality
You need to know how to test whether people want the outcome. A spreadsheet, a phone number and you doing the work manually can validate most ideas long before any product needs to exist.
The myth
"If I build it well, people will come."
The reality
Distribution — how strangers will actually hear about and trust you — is part of the idea, not a problem for later. If you can't name your first ten customers and how you'll reach them, the idea isn't ready to build yet.
The myth
"Successful founders had it figured out from day one."
The reality
Most successful businesses look nothing like their founders' first version of the idea. What didn't change was the discipline of testing small, listening honestly and adjusting fast.
08 / Your first two weeks
Stop reading. Start with this.
Six steps, in order. None of them require funding, a co-founder or permission from anyone.
- 1
Write your idea as one sentence: for [specific person], who struggles with [specific problem], we help by [specific action].
- 2
Find five people who actually match that 'specific person' and talk to them this week — not a survey, an actual conversation.
- 3
Ask what they currently do about the problem today, and whether they already pay for any part of a fix.
- 4
Decide the smallest possible version of your idea that would let you learn if they'd really use it.
- 5
Set your affordable loss — the maximum time and money you'll spend before deciding whether to continue.
- 6
Get one real commitment (money, time or a public yes) from someone outside your immediate friend group.
09 / More in the playbook
Short courses, each with a slide deck.
The Founder's Playbook is a growing set of short, original courses — each one readable here and downloadable as a slide deck for your own use.
Winning once is easy. Staying ahead is the actual test.
Building a Durable Competitive Advantage
Five short modules on what actually makes a business defensible over time — cost and efficiency, differentiation, switching costs and network effects — plus a simple test for whether your own idea would survive a well-funded copycat.
Every rupee of outside money changes who you answer to.
Raising Money Without Losing the Company
Bootstrapping vs. debt vs. equity, the four questions behind every investor's yes or no, a fully worked dilution example across two funding rounds, and four honest reasons not to raise yet.
"People seem to like it" is a feeling. This is a fact you can chart.
Finding Product-Market Fit
Three retention-curve shapes and what each one actually means, three honest signals to check before trusting a dashboard, and exactly what to do while the curve still looks weak.
Your first hires define what the company can do before there's a process to lean on.
Hiring Your First Five People
Four traits that matter more than a strong resume, four rules for early equity that prevent most future disputes, and the co-founder mistakes that quietly break companies later.
One idea. Three genuinely different two-minute pitches.
Pitching and Storytelling
What an investor, a customer and a prospective hire are each actually listening for, a six-step structure that works for any two-minute pitch, and the four mistakes that make pitches forgettable.
Keep building
Ideas are cheap. Shipped things aren't.
One of my own Side Quests — a live beta app I built and put in front of real users — is exactly this philosophy applied to my own work, not just taught to students.
