"If you're reading this, you're probably in the thick of it."

Spreadsheets with 15 tabs. Conflicting advice from well-meaning relatives. A counselor who sees 400 students. The nagging feeling that you're missing something important—but you don't know what.

CollegeStack doesn't make the process easy. Nothing can. But it makes the uncertainty manageable. It turns "I think we're okay" into "I can see exactly where we stand."

From uncertainty to clarity

Watch how a typical college list transforms when you can actually see what's happening.

⚠️ Critical Risk

The Fake Safety

"Your safety school rejected 40% of applicants with your daughter's profile last year. That's not a safety—that's a coin flip."

⚡ Yield Trap

Over-Qualification Risk

"Northeastern historically rejects high-stat EA applicants—they're protecting yield. Consider ED or demonstrating interest first."

💡 Opportunity

The ED Advantage

"Applying ED to Tulane gives you a +35% boost based on historical data. That moves it from Reach to solid Target."

Questions? We've got answers.

No—and anyone who guarantees college admissions outcomes is misleading you. CollegeStack provides probabilistic, range-based estimates to help you make informed decisions. We help you build a structurally sound strategy; the outcomes still depend on many factors beyond anyone's control.

We use publicly available data from IPEDS, College Scorecard, and Common Data Sets—the same sources that professional counselors use. We normalize and combine this data to produce portfolio-level insights that would take hours to calculate manually.

CollegeStack complements your counselor—it doesn't replace them. We provide the quantitative portfolio analysis that's hard to do manually when a counselor has hundreds of students. Think of it as the data layer that makes your counselor conversations more productive.

Yes. We never sell your data, share it with colleges, or use it for advertising. Your information is used solely to generate your portfolio analysis. You can delete your account and all associated data at any time.
