It does great with donor cultivation processes and the workflow feature is top-notch for automating processes. Where it does a less than stellar job is getting it to work more specifically for your organization. Often times building that kind of special feature costs a significant time and money investment and it is something that is hard to transfer when it's time to move to a new database.
It is well suited in a public media organization that uses a separate tool for tracking donor touches and engagement and has a separate donation page. In my opinion, it is not a great use case if you are looking for something intuitive or easy to use.
Support for the product is horrible; often support will have you bouncing between Blackbaud support and Salesforce support and it's very rare either are able to find simple solutions. Most of the time the solutions almost always cost money and hiring consultants which, for a smaller organization, means not being able to achieve proper solutions.
Of the databases I have used, Luminate CRM is my least favorite. However, it is powerful and large enough to function adequately for a large nonprofit; I couldn't say the same for some of Blackbaud's smaller products. We definitely need the full Luminate Suite (Luminate Online, Team Raiser, etc.,) to make it work, though - and we're constantly disappointed by the clumsiness of the way all the pieces interact.
MemSys was selected because of its features specific to public media. Unfortunately, in my opinion, it does not show features that would enable it to compete with other CRM systems well.
