In these scenarios, they are typically working with companies that already have Salesforce implemented but it's not delivering as much value to the business as desired. Unlike an Implementation Partner, these companies are working with an existing Salesforce foundation and trying to identify new functionality to build, issues or bugs in the current code, and integrations that aren't functioning properly.

is most often a monthly retainer. At the start of the engagement, a monthly fee is agreed to in exchange for a set numbers of hours that Partner will allocate to the project.
The expectation is for this to be an ongoing partnership.
A company will want to bring on Optimization Partners if they aren't sure what type of projects they should be thinking about for Salesforce. This is a platform designed to scale as your business evolves, so if you aren't constantly making changes to the tool then you will run into issues.
