What do you like best?
Nothing. Their sales people will tell you that Apto will do anything you want it to; don't believe them. I think they are on a tear to grab as much market share as they can to make themselves a buy-out/take-over candidate or to sell out to a more "real" competitor.
What do you dislike?
After repeated affirmations from their sales and tech support staff that the program would do what I wanted - which was to link contacts to properties to related lending sources (debt and equity) - it did none of those things. They wasted eight months of implementation time, and ever after never having used the program, I had to fight with them to obtain a full refund. I was also never made aware at all about the OEM and Embedded Licensing restrictions that these 'app skin' providers face as part of using SalesForce as their data engine. This severely limits the customization and flexibility required in designing a truly dynamic, interactive, and robust database.
Recommendations to others considering the product
All of the CRE CRM programs offer widely different features, and appeal to users of diverse technological and CRE skill sets. I would strongly recommend that in addition to honestly assessing your tech savvy, and how much of an IT/administration role you want to play in the implementation and data management process, to identify the top five most important things you want your database to accomplish for you. Some users will want an multi-layered, inter-relational database with all data fields connected and referenced - while others may want customizable reporting, pipeline tracking, deal progression, and something that facilitates more back-office operations. I also suggest obtaining a customized demo or tutorial showing EXACTLY how that program will meet your most important needs. Many offer free trial periods, or will allow you to access a 'dummy' database so you can directly test the features that are most important.
What business problems are you solving with the product? What benefits have you realized?
The only thing Apto provided me was an 8-month delay in my data implementation. There was no benefit - only agita and frustration.
