£329. One payment. Someone just paid for a full year upfront.
It's happened a few times now and it still hits the same way every time.
Three and a half months ago I was refreshing Stripe hoping for a single $24 sale. I screenshotted the first one.
I built this because I kept scaring myself. Vibe-coding my own projects with Claude Code, shipping fast, feeling great, then actually looking at what I'd put live: API keys in the frontend, RLS I never turned on, buckets wide open. With real users on them.
Two of us. Zero on ads. Final school exams running while we launched.
Most days building this is quiet. Nothing moves. You fix things nobody has asked about yet and go to bed.
Then this lands and you remember why you started.
The grind is never the glamorous part. The proof it's working shows up in a notification you weren't expecting.

If I had to get a SaaS its first 5,000 users with $0 in ad spend, here's exactly what I'd do.

Most founders reach for ads before they have one thing people actually want to share.

Make the product itself the hook. Ours is a free 60-second scan that finds real security holes in AI-built apps.
Post it native on TikTok as slideshows. No branding on the slides, no logo, just the tools you actually use and your own product.
Write value-first Reddit posts in the vibe-coding subs. Teach first, never pitch.
Turn every real finding into its own piece of content.

That mix got us to 5,000 signups and 200 all time paying users, all organic, while we're still 19.

The product should be the ad.
