  The status quo is unacceptable.





















  
  




  67%Percentage of industry leaders in North America that agree clients are often sold inappropriate financial products.Source


  
    
    


  
  





  Inappropriate products result in hidden or unnecessary costs.

























You’re especially vulnerable to certain costs if your “advisor” works for a bank or brokerage firm. The various fees and expenses add up fast, often reaching 2.0% per year or more. 
























  
    
    


  
  





  Excessive fees devastate your nest egg over time.





















  
  




  40%Percentage of your portfolio lost to annual fees and expenses of 2.0% over a 40-year period.$1 saved annually and invested at 7.0% = $214$1 saved annually and invested at 5.0% = $127


  
    
    


  
  





  But smart investors are catching on.

























Bogleheads, YouTube, Reddit—access to expertise is freely available to those that know how to parse it. Smart, industrious investors are fleeing broker-dealers and active management in favor of independent advisors and index funds. 
























  
    
    


  
  





  In an industry focused on selling products instead of providing advice, who can you trust?
























  You.Our vision of the future requires giving people direct access to professional-grade financial planning software. If you’re less reliant on pros for sophisticated tools, then you’re also less vulnerable to industry salesmanship that often does more harm than good.


  
    
    


  
  





  We're building tools for you right now. You might as well help.
