How to start a business in 2026
A no-fluff, step-by-step playbook for first-time founders. Size the market, write a real plan, pick the right website, ship content and start collecting email addresses — in that order.
Most "how to start a business" guides are written by people who've never started one. They list 47 steps, recommend forming an LLC before you have a customer, and somehow forget that the only thing that actually matters in year one is proof that someone will pay you.
This playbook is the opposite. It's the exact sequence we run new founders through at Billionideas: size the market, get the plan onto one page, put a real website live, ship a piece of content, and start a newsletter so you own the audience you're building. Each step links to a full tutorial with screenshots, templates and the gotchas nobody warns you about.
TAM, SAM, SOM — calculate your market size
Top-down and bottom-up market sizing with worked examples, sanity checks and the exact formulas investors expect to see.
Why it matters: Before you build anything, prove the market is big enough to matter — and small enough that you can actually win a slice of it.
The one-page business plan (with template)
A modern, lean alternative to the 40-page document. Problem, customer, offer, channels, economics and the next 90 days — on one page.
Why it matters: Investors, co-founders and your future self all read the one-pager. Long plans get skimmed; one-pagers get acted on.
Wix vs Squarespace in 2026 — which to choose
Side-by-side on design freedom, SEO, e-commerce, pricing and migration pain. Plus when Framer or Webflow beat both.
Why it matters: Your website is the single biggest lever for early traction. Pick wrong and you'll re-platform inside a year.
Build a blog with Framer CMS
Set up collections, design a post template, wire SEO meta and publish your first article — without writing code.
Why it matters: Owned content compounds. A blog with even 10 well-targeted posts can outrank paid ads inside 6–12 months.
Launch a newsletter with Beehiiv
From workspace setup to your first send — custom domain, sign-up forms, monetisation and the cadence that actually retains readers.
Why it matters: An email list is the only audience you fully own. Start collecting addresses on day one, not after launch.
