Building SaaSurfer in 12 days to sell - Day 7 update (Reddit validation tool)
Hey IH community! 👋
I'm Ayesha, a designer who decided to build and sell her first
full-stack app in 12 days. Here's my Day 8 update.
What I Built
SaaSurfer - A tool that validates SaaS ideas by scanning
Reddit for demand signals.
How it works:
- Describe your SaaS idea
- SaaSurfer scans 20+ startup subreddits
- Get a demand score (0-10) + actual Reddit posts as evidence
Built for indie hackers who want to validate BEFORE building.
Why Building to Sell
I'm learning full-stack with AI tools (Cursor + Claude). My goal:
- Learn by building something real
- Sell the finished product (~$2,200)
- Fund the next project
Timeline pressure (12 days) keeps me shipping instead of perfecting!
Progress So Far
- ✅ Days 1-2: PRD + Wireframes
- ✅ Days 3-4: Working full-stack app
- ✅ Days 5-6: Professional UI + mobile responsive
- ✅ Day 7: Payment system (freemium model with paywall)
- ✅ Day 8: Demo video + deployment (in progress)
- ⏳ Days 9-10: Documentation
- ⏳ Day 11: List for acquisition
Tech Stack
- Frontend: React 18 + Vite + Material UI
- Backend: Node.js + Express
- Payment: Freemium UI built (3 free → $19 paywall)
- Deployment: Vercel
Biggest Lessons
Building to sell changes everything:
- Ship > Perfect - "Good enough" is the goal
- Timeline pressure works - Deadline = decisions
- Features by sale value - Only build what adds price
- Docs = code - README matters as much as React
What surprised me:
- AI tools made this possible (zero backend experience)
- Payment processors are harder than coding (LemonSqueezy rejected)
- Mock data is fine for demos (buyers understand)
Honest Challenges
-
Reddit banned my dev account 😅
Built with realistic mock data, real API ready to connect -
LemonSqueezy rejected application
Built payment UI anyway, buyer connects their processor -
Learning curve as designer
Terminal, debugging, ports - AI made it manageable
Questions for the Community
-
Where do you sell pre-revenue tools?
Flippa? Direct sales? What's worked for you? -
Is $2,000-2,200 reasonable for:
- Working React + Node app
- Payment UI built (freemium model)
- Clean code + documentation
- Zero revenue (pre-revenue)
-
Demo video advice?
Should I show code or just product? Length?
What's Next
- Finishing demo video today
- Deploying to Vercel (live URL)
- Writing docs tomorrow
- Listing Day 11 (Flippa + direct sales)

Happy to answer questions about building with AI tools or
the acquisition strategy!
Awesome progress in 12 days — but right now SaaSurfer reads like another “validation tool” unless you make it obvious what makes it better than Reddit + existing trend trackers.
Highlighting specific use cases, early wins, or a crisp value prop will make people stop scrolling and actually sign up — not just skim.
If you want a quick, outside perspective that sharpens your messaging and boosts sign‑ups, happy to help ✨
That is such a valid point, and I really appreciate the sharp perspective! 🙏
You're 100% right—'validation tool' can sound a bit generic. My goal with SaaSurfer is to bridge the gap between 'I have an idea' and 'I just spent 3 hours manual-searching Reddit.' Instead of just tracking trends, it gives you a 0-10 demand score based on actual posts where people are complaining about the problem you're trying to solve. It’s about getting that 'Go/No-Go' signal in 30 seconds.
I'm leaning heavily into the UX of validation—making the evidence so clear that you can't ignore it.
I'd love to hear more about how you think I could sharpen that messaging further. I’m building this to sell on a tight timeline, so every bit of clarity helps.
Thanks for the support!
Awesome — quick question first so I tailor feedback:
Are you most focused on getting more signups, proving traction, or tightening the core value proposition right now?
Once I know the priority, I can point to 2–3 concrete tweaks that will make a real difference
