I built my first SaaS back in 2023. Spent months coding. Launched to crickets. Zero users. Zero revenue. Just a lot of regret.
I made every beginner mistake you can make. But I learned a ton from it and now I help other founders avoid the same traps.
Here are the biggest lessons that changed how I build now.
Lesson 1: Solve a problem you actually understand
I built a tool for real estate agents. I had never sold a house in my life.
I thought I understood their problems. I didn't. I was guessing.
If you're not in the industry you're building for, go talk to people who are. Spend a week just interviewing potential users. Ask them what sucks about their job. You'll find gold.
Lesson 2: Build the stupidest version possible
My first product had Stripe integration, team accounts, email notifications, and a dashboard with 12 different charts.
What it didn't have was a single feature anyone actually asked for.
Now I strip everything down to one core action. What is the one thing your user needs to do? Build just that. Nothing else. If they can't use your product to solve their main problem, all those extra features are worthless.
Lesson 3: Get it in front of people immediately
I kept my product hidden for 6 months. I was embarrassed to show it. I wanted it to be perfect.
That was stupid.
Show your product to someone on day 3. Even if it's ugly. Even if it barely works. Early feedback is the most valuable thing you can get. It hurts less to hear "this is wrong" on week 1 than on month 6.
Lesson 4: Charge money from the start
I launched free. Got 200 signups. Felt great.
Then I added pricing and almost nobody converted. Free users expect free forever.
Start with a price. Even $10 a month. It forces you to build something valuable enough that people will actually pay for. If nobody pays, you learn that early and move on.
Lesson 5: Marketing starts before you write code
I thought if I built it, they would come. They didn't.
Start talking about your product on day one. Post about it. Tweet about it. Tell everyone you know. Build an email list of interested people before you have anything to sell.
Launch day should be exciting, not lonely.
That's what years of building taught me. I've made all these mistakes so you don't have to.
If you're working on something and want a second pair of eyes on your plan, drop it in the comments. Happy to give honest feedback.
Or if you just want someone to build that first working version fast so you can start testing without spending months coding, feel free to comment also. I do that for founders.
Otherwise, good luck. Keep building.
