I'm 18 and a senior in high school. Over the past couple months I built AdmitOdds (https://admitodds.com), an AI-powered tool that estimates your real chances of getting into any US college.
You enter your GPA, test scores, extracurriculars, and other stats, and it gives you a percentage chance for each school plus specific advice on what to improve.
The tech:
- Frontend on Vercel (Next.js)
- Backend on Supabase
- AI predictions using Claude and GPT
- Stripe for payments
Where it's at now:
- 415 users signed up
- 18 paying subscribers ($19.99/month)
- Growing mostly through Reddit and Instagram
Why I built it:
I went through the college application process myself and hated how opaque it felt. Every advisor gave different advice. The existing tools (Niche, CollegeVine) felt outdated or too generic. I wanted something that actually gave you real, data-driven odds and told you what to work on.
What I learned:
- Building the product was the easy part. Getting people to pay for it is where the real challenge starts.
- Teens are not great customers. Their parents are. Had to rethink my entire messaging strategy.
- Reddit is the best free marketing channel I've found. Being genuine and helpful beats running ads every time.
