The problem
Every investor has a spreadsheet. Most of them are broken — wrong formulas, missing expenses, no way to quickly compare loan types. Too much time debugging Excel, not enough time analyzing deals.
The solution
Caprium does one thing well: take a property address and financing assumptions, and output every metric an investor needs to make a buy/pass decision. No manual data entry for rent or taxes. No formula errors. No 47-tab spreadsheets.
What we believe
- Every number should show its source and confidence level
- Analysis should take seconds, not hours
- The tool should be opinionated about what matters and transparent about how it calculates
- Investors deserve better than spreadsheets and back-of-napkin math
