Weiss Analytics is seeking $3 million to grow its real estate technology platform providing automated individual house valuations, and housing valuation data that has the ability to forecast market turns up to one year ahead of the Case-Shiller Index.

-Allan Weiss, the founder and CEO of Weiss Analytics, co-founded Case Shiller Weiss (producer of the S&P Case-Shiller index) and served as CEO from inception to its sale to Fiserv in 2002

-Weiss Analytics produces automated individual house valuations, based on our proprietary indexes, multiple AI models, and additional AI when property photos are available. 

-Weiss Analytics believes it has valuation accuracies that gives it the potential to garner 15-20% of the current $100MM annual US AVM market.



  • The US housing market is the largest and most inefficient market in the world: $40 trillion in assets that customers have difficulty pricing accurately
  • US Financial Institutions face growing residential property value risk
  • Lenders
  • Property Insurance Cos
  • Investors
  • Realtors and Consumers
  • Financial Institutions are managing risk by supplementing appraisals with fully automated valuations and AI driven workbench tools for appraisers and analysts

Competitive Advantange

The fuel of all property valuations are past prices

Past prices must be adjusted to the present with a time adjustment

Weiss Analytics’ indexes produce more accurate time adjustments for all comparable sales (comps) and allow for effective use of older comps, resulting in:

Increased number of comps
+ Higher quality (more similar) comps, and
+ The use of prior sales of the subject house as a comp
= More accurate valuations
