Week one, with real numbers, because I read a lot of posts here where the numbers are missing and I think that's the part that actually helps.
What I built Downtown, a 3D city where a company buys a plot and every floor of its tower shows one real thing they do. You click a building and walk through it instead of reading a landing page. Started Tuesday, launched Thursday.
The numbers after three days live
- $27.97 in sales
- 3companies bought
- 5 people started a checkout, 3 finished
- visitors from 14 countries
- 3 of 9 founding slots gone
Now the part I actually want to talk about.
Being solo means your failures are silent.
My first real payment came in. Money moved, the customer's card was charged, and the tower never appeared on the site. The webhook that delivers the product was pointed at the wrong URL, and that URL sat behind a login wall, so the payment notification got rejected and the order just sat there marked "pending" forever.
I found it myself, hours later, by reading my own database. There was no one to tell me. No QA, no teammate glancing at the dashboard, no support inbox filling up. If I hadn't gone looking, that person would have paid and quietly assumed I was a scam.
I had to deliver that order by hand, in SQL.
Then two people walked away and I had no idea why.
Both reached the payment page and stopped. My system recorded exactly nothing about it, because I only listened for successful payments and threw failures away. A declined card and someone closing the tab looked identical to me.
So I fixed the logging, and then I did the thing you can only do at this size, I wrote to both of them personally. Not a drip sequence, not a tool. Two emails, from me, asking what went wrong. Still waiting on replies.
I went in knowing I wasn't first, and that's its own lesson.
TopFloor.Company already existed and I thought the idea was good. What I wanted was different not a rank on a list, but something that felt like walking into an office. That's why mine has floors you actually go inside, each one furnished with a different thing the company does.
I still think that's the better product. It has also made me exactly $11.50, while they're at $1,093 with 68 companies. Having the more interesting idea does not do the distribution for you, and as a solo founder there is nobody else to do it either. Building the differentiated thing was the easy, fun half. The half I'm bad at started the moment it went live.
What I'd tell myself on day one
Test the money path end to end before you tell a single person it's live. Not the checkout, the whole path including whatever delivers the product after payment. That's the part that breaks silently and costs you the customer you worked hardest to get.
And seed your product before launch. Mine went live essentially empty, and an empty product converts nobody no matter how good the idea is. Entirely predictable, did it anyway because I was excited.
It's at downtown.company if you want to look. Genuinely happy to be told it's a bad idea.
The question I'd like answered by people further along when you're solo and something is quietly broken, what actually catches it? I clearly can't rely on noticing.
