How to start a startup comes down to one first decision: is there a customer need worth solving? Test that with real customer conversations before you spend on registration, product or funding, then move through team, plan, legal setup, funding, MVP and launch.
This guide follows that order. Each section ends with the point where you should pause and check before moving on, and the linked guides go deeper on individual steps.
Choose your starting point
Where you begin depends on what you already have, not on what looks most impressive. A startup needs three things, according to Paul Graham’s essay on starting a startup: good people, a product customers want, and low spending. Match your current gap to the right first section below.
- You have no idea yet. Start with the idea and validation section. A customer need that is unmet, or that can be solved another way, is the usual trigger for a startup, so look for problems before you look for products. For a structured search, see How To Find Startup Ideas: A Practical 2026 Playbook For Founders – Startalliance.
- You have an idea but have not talked to customers. Do the validation work before anything else. Registering a company or building software can wait until you know whether anyone cares.
- You have an idea and customer interest but work alone. Go to the team section. A startup is easier to build with a range of skills in the room, even if the team is small.
- You have a team and a validated problem. Move to the plan, legal setup and funding sections, then build the minimum viable product.
- You are already selling something informally. Check the legal setup section next, so your registration, licences and contracts match what you are already doing.
If you are unsure which bullet fits, pick the earliest one that is not fully done. Skipping ahead is the common way to pay for a product nobody asked for.
The launch sequence at a glance
The Estonian government’s e-Residency programme lays out nine essential steps to start a startup, running from finding a business idea through to growth. J.P. Morgan frames the same journey as ten key steps. The count differs because the two sources split the work differently, not because they disagree about the direction. Use this checklist as a practical blend, and treat each line as something you can tick off with evidence.
- Find and shape the idea. You can name the customer need and who has it.
- Research and test viability. You have spoken to potential customers and studied competitors.
- Assemble the team. The skills you need are covered by people committed to the goal.
- Write the plan. Your objectives, target market, products and competition sit on paper.
- Set up the legal structure. You have chosen between operating as a sole proprietor and forming a company, and you have registered.
- Size your cash needs. You know how long your money lasts without income.
- Line up funding. You have chosen the sources that suit your stage.
- Build the minimum viable product. It is good enough to test with real users.
- Launch and grow. You are tracking what customers do and adjusting.
The sequence is a guide, not a rule. Founders often run planning and customer research side by side, and funding conversations can start before the product is finished. What should not move is validation: it comes before spending. For the operational detail of launch day and what follows, how to launch a startup has the full checklist.
Idea and validation
Validating an idea means finding out whether a real customer need exists and whether your solution is viable before you commit. The e-Residency guide notes that ideas typically arise in response to an identified customer need that is either not being met or could be met differently. It adds that you need to research and test the idea first to see whether it is actually viable.
Test with customer conversations
Customer conversations are the most direct test. J.P. Morgan’s startup guide gives targets: ideally around 100 consumer prospects, or at least 15 potential clients when you sell to businesses. Those figures are a sensible planning target for how many people to talk to, not a guarantee that a given count proves demand. The business-to-business number is lower because each conversation involves a company and fewer buyers exist.
- Selling to consumers. Aim toward the larger conversation count, and look for patterns in what people say they currently do about the problem.
- Selling to businesses. Treat the lower number as a floor. Go beyond it if the answers differ widely between companies.
- Hearing mixed answers. Do not average them. Look for the segment that feels the problem most and focus there.
For what to ask, customer discovery interview questions covers question design, and how to validate a startup idea covers the wider process of testing before you build. If your interviews keep returning to the same pain point, problem solution fit explains how to tell whether your solution matches it.
Study the competition
The e-Residency guide calls thorough competitor research important. Treat competitors as evidence that the problem is real, then look for what customers still lack. Write down who else serves the same customer, what they charge and where customers complain. How to do market research for a startup shows how to size your market and structure the competitor review.
Say why a customer should choose you
Once the research points to a gap, put it into a single plain statement of the value you offer. That statement should survive a customer conversation unchanged. If you have to re-explain it each time, the problem or the audience is probably still unclear. How to write a value proposition walks through drafting it, and a lean canvas template gives you a one-page place to keep the problem, customer and solution together while you test.
Check before moving on: you can describe the customer need in one sentence, you have heard it from several people in your own words rather than yours, and you know who already competes for that customer.
Team and co-founders
A co-founder is a person who shares the work, risk and ownership of building the company from the start. The e-Residency guide names having a team as one of the most important success factors, with a range of skills even if the team is small. IE University’s startup guide adds that a lasting culture needs clear communication and a team aligned on its goals.
Paul Graham’s essay makes the same point from the founders’ side: start with good people. He also says that in a technology startup, which most startups are, the founders should include technical people. If you cannot build the product yourself, a technical co-founder is a core hire, not a later add-on.
Choose partners for complementary skills and shared goals, not only friendship. Before you commit, ask each person what they expect to do, how much time they will give and what happens if one of you leaves. How to find a co-founder covers where to look and what to agree on, and a co-founder agreement template lists the terms to put in writing. Splitting ownership is its own conversation: How To Divide Equity In A Startup: A Practical 2026 Guide To Fair Founder Splits – Startalliance covers fair founder splits, and How Startup Equity Really Works: A Practical 2026 Guide To Ownership, Vesting, And Value – Startalliance explains vesting and value.
Check before moving on: every critical skill has an owner, and each partner has said out loud what they expect from the others.
Business plan and model
A business plan acts as a roadmap for your startup. J.P. Morgan says it should outline your objectives, target market, products and competition. The e-Residency guide stresses that plans do not have to be extensive and that founders often use very rough ones. Write the shortest version that makes you commit to choices, and expand it only when someone you need, such as a lender or partner, asks for more detail. A startup business plan template gives you a one-page structure for first-time founders.
The plan is also where you decide how the company earns money. Compare startup business model examples to choose a revenue model, then test the price with customers using how to price a new product. Put the numbers in a startup financial model template so your cash needs rest on stated assumptions rather than hunches.
Check before moving on: someone outside the team can read the plan and tell you who the customer is, how you earn money and what you will do first.
Legal setup and business registration
The central legal choice is structure. The e-Residency guide frames it as a question: start as a sole proprietor, or form a company for its legal protection. Forming a company is the path most founders with partners and outside funding weigh most seriously. J.P. Morgan describes incorporating your startup as one of the most important legal steps.
What the legal steps involve
IE University’s guide lists the practical sequence after planning: apply for a business license, get the business registered and set up your contracts. Which licences, forms and fees apply depends on your country and your activity, so check with your local business registration agency before you file. How to incorporate a startup compares company types and walks through filing in the United States.
Registering remotely
If you are not based where you want your company to sit, a remote route may exist. The e-Residency programme enables founders to establish a private limited company (OÜ) in Estonia, with the process handled remotely. Whether that suits you depends on where you will sell, bank and hire, so treat it as one option to weigh against registering at home.
Protecting what you build
Once the company exists, look at ownership of the idea and exposure to risk. How to protect a startup idea explains trademarks, patents and NDAs, and what insurance does a startup need covers coverage. A trademark choice starts with a name, so see Startup Name Ideas: 50 Creative, Memorable Options And How To Choose The Right One In 2026 – Startalliance before you register one.
Check before moving on: you have chosen a structure deliberately, you know which licences your activity needs, and your contracts exist in writing.
How much money you need
The amount depends almost entirely on whether you need a physical presence. IE University’s guide says a low-cost startup with an online start may need only a small sum. If you need a physical location, it says costs can climb much higher for rent, equipment and inventory. Those ends of the range tell you more than any average: decide first which kind of business you are building.
- Online and low-cost. Your early budget is mostly small recurring tools and your own time. The risk is underestimating how long you will be working without income, not the cash outlay.
- Physical location. Rent, equipment and inventory dominate, so test demand in a cheaper form first, such as a pop-up or pre-orders, before signing a lease.
A second planning rule applies to both. IE University advises that you have enough money ready to cover the first six months of operations without projected income. Treat that as a minimum runway to plan around, not a promise that six months is enough. If your product takes longer to reach customers, extend it. For a full breakdown of cost categories, see how much does it cost to start a startup, and use a startup budget template to plan spending month by month.
Funding routes compared
Startup funding is rarely a single source. The e-Residency guide describes a typical path: bootstrapping first, then a combination of venture capital, business loans, angels, accelerators and incubators. IE University’s advice is blunter: get funding wherever you can, from loans, investors, friends and family. The table compares the routes named in those two sources so you can match each to your stage.
| Funding route | Where it fits | Planning use |
|---|---|---|
| Bootstrapping | The starting point before outside money | Stretch your own resources while you validate, so you raise later with evidence |
| Friends and family | Early funding when formal investors are not yet interested | Agree terms in writing so a personal relationship does not carry business risk |
| Business loans | Part of the combined funding path after bootstrapping | Check what lenders require before you apply |
| Angel investors | Early outside investment, alongside other sources | Prepare a clear plan and customer evidence before the first meeting |
| Venture capital | A later part of the combined path | Consider once you can show traction and a larger plan |
| Accelerators and incubators | Support programmes that sit alongside funding | Compare programmes by what they offer, not only by name |
| Crowdfunding and local contests | Platforms such as Kickstarter or Indiegogo, and contests that offer funding and exposure | Use when your product can attract early backers or publicity |
| Keeping your day job | A low-glamour option that gives you a steady income while you build | Best when you need runway without giving up any ownership |
Funding routes here are drawn from the e-Residency startup guide and IE University’s startup guide.
Choosing among them
- You want to keep full ownership. Lean on bootstrapping, your day job and contests. For grants, loans and crowdfunding that do not take ownership, see non dilutive funding for startups.
- You need debt and have no sales yet. Read about startup business loans with no revenue before approaching a lender.
- You want investors. Start with how to find angel investors, then see how to raise money for a startup for the full comparison, and Pre-Seed Vs Seed Funding: How To Know Which Round Is Right For Your Startup In 2026 – Startalliance to match the round to your stage.
- You want structured support. Compare accelerator vs incubator before applying to either.
Preparing to talk to investors
Selling shares means ownership changes, so understand it first. Build what is a cap table to see who owns what, read Startup Equity Dilution: How To Protect Your Ownership While Raising Capital In 2026 – Startalliance to understand the cost of each round, and see How To Sell Startup Equity In 2026: Practical Steps To Raise Cash Without Killing Growth – Startalliance for the selling process. A Startup Valuation Calculator: Estimate Your Company’s Worth Fast — A Practical 2026 Guide – Startalliance helps you form a view of price before the meeting. When you are ready to present, a startup pitch deck template shows the slides investors expect, and the startup due diligence checklist helps you assemble the documents they will request.
Build the minimum viable product and launch
The e-Residency guide places the next move after planning and funding: create a minimum viable product (MVP) and launch your product or service. An MVP is the simplest version that lets real users do the core job you promised, so you can learn from them. Keep it small enough that a wrong guess costs little.
You may not need to write code to test the idea. How to build a prototype for a startup shows ways to put something in front of users before development, and the Minimum Viable Product Checklist: Build Faster, Test Smarter In 2026 – Startalliance lists what to include and what to leave out.
Launching is the start of learning, not the end of the work. Decide beforehand what you will measure and what result would make you change course. The checklist for the days before and after launch is in how to launch a startup.
Avoiding early mistakes and building knowledge
Most first-year problems trace back to skipped steps in this guide: building before validating, forming a team without clear agreements, or spending without a runway. For a fuller catalogue, read why do startups fail and compare it with your own checklist.
Keep learning as you build. A shortlist of best startup books and free courses gives first-time founders a place to start, and the sources linked throughout this guide are short enough to read in a sitting.
Frequently asked questions
Do I need a brilliant idea to start a startup?
No. Paul Graham writes that you do not need a brilliant idea to build a startup around. What counts is a real customer need, good people and disciplined spending.
How many founders should a startup have?
Paul Graham’s guidance is ideally between two and four founders. In a technology startup, at least one should be technical.
Will funders ask to see a business plan?
Many government funders require a business plan as part of the funding application, according to the e-Residency guide. It can still be short and rough, so write the version your funder actually asks for.
Is keeping my day job a sensible way to fund a startup?
IE University calls holding on to your day job a not-very-sexy option, but it gives steady income while you build and does not require outside investors.
