I recently came across one company that neatly falls into this category. They are called ValueAppeal and they answer a very specific question:
Are you paying too much in property taxes?
ValueAppeal saves property owners thousands by evaluating their property taxes and then guiding them through a simple 3-step process to create a custom appeal. The key to our process is our proprietary Assessment Analyzer.
Enter your address in our free Assessment Analyzer. Using the same official data the assessor uses, ValueAppeal’s proprietary algorithms dig deep to determine if your home is over-assessed and how much you can save on property taxes!
For a one-time fee of $99 (with money back guarantee) the company has seen average savings of close to $900
There are three things which are very interesting and clever about the solution:
1) it uses the available public data and not any proprietary dataset
2) the analytical algorithm focuses on the datapoints that helps to make a favorable case
3) it generates a report that can be simply printed out a dropped into the mail by the user
Please drop a note if you have seen other interesting companies which develop such niche analytics based decision support solutions.
