Walk into any startup meeting and you will hear it within minutes. “We’re pre-revenue, but our burn is low and we’re chasing product-market fit before the seed round.”

If that sentence made your head spin, you are not alone. Startup talk is a mix of business, money, marketing and tech words, and most people pick them up slowly, one awkward meeting at a time.

This guide skips the jargon. Every term below is explained in simple words, with a short example where it helps. Bookmark it, share it with your co-founder, and come back whenever a new word pops up.

What is a startup, exactly?

A startup is a young company built to solve a problem in a new way and grow fast. A corner tea stall is a small business. A company that builds an app to deliver tea to a million offices across the country is a startup. The difference is the plan to grow big, quickly, often with the help of technology.

Part 1: Words about people and mindset

Co-founder: Someone who starts the company with you and shares the risk, the workload and the ownership.

Technical founder: A founder who can build the product, usually by coding.

Non-technical founder: A founder who focuses on sales, marketing, partnerships, money or operations rather than code.

Wantrepreneur: Someone who talks about starting a business for years but never takes the first step. The fix is simple: start small, start now.

Mentor: An experienced person who gives advice, usually without being paid, to help you avoid mistakes they already made.

Advisory board or board of directors: A group of experienced people who guide the company’s big decisions. A formal board of directors also has legal power over major matters.

MVP (Minimum Viable Product): The simplest version of your product that still works and lets you learn from real users. Think of a food delivery startup that begins with a simple WhatsApp group and a few riders, not a full app.

Prototype: A rough model or sketch of the product, used to show the idea. It may not work yet.

Iteration: A small improvement based on feedback. Startups make dozens of these.

Pivot: A big change in direction, such as a new customer, a new product or a new way of earning money. Many famous companies started as something completely different.

Fail fast: The idea that it is better to test quickly, learn from small failures and move on than to spend years on something that does not work.

Lean startup: A way of working where you build a little, measure the results, learn, and repeat, instead of building a big product in secret.

Agile: A way of building software in small steps, with regular check-ins and quick changes, rather than one huge plan.

Alpha and beta testing: Alpha testing is done inside the team. Beta testing is done with a small group of outside users before the public launch.

Product-market fit: The sweet spot where a good number of customers really want your product, keep using it and tell others about it. Founders often say things feel easier after reaching it, because customers start pulling the product instead of you pushing it.

Value proposition: A short statement of why a customer should pick you. It answers one question: what problem do you solve, and why are you better?

Freemium: A free basic plan to attract users, with paid plans for extra features.

Marketplace: A platform that connects buyers and sellers and takes a small cut, like a booking or freelancing site.

Scalability: The ability to serve many more customers without costs growing at the same speed. Software scales well because one product can serve thousands of people.

Disruption: When a new company changes an entire industry by doing something much simpler, cheaper or better than the old players.

Part 4: Words about money and funding

Bootstrapping: Building your company with your own savings and early sales, without outside investors. You keep full control, but growth may be slower.

Venture capital (VC): A firm that invests other people’s money into startups with big growth potential. VCs usually come in when a startup already shows early results.

Pre-seed and seed round: The earliest rounds of outside funding. This money is used to build the first product and find the first customers.

Revenue: All the money coming in from sales, before expenses.

Cash flow: The money moving in and out of your bank account. Many startups fail not because the idea is bad, but because the cash runs out.
