I am looking for a partner to help my company re-invent and re-imagine our customer engagement strategy.  Does anyone have a recommendation on a vendor or consultancy that is good at facilitating a discovery and strategy plan for something like this?  How do we cross-sell among the company's brands?  Do we de-emphasize the brands to focus on benefits or do we emphasize the brands as a way of making the presentation of value simpler?

I have used Omnicon, based in Columbia, for the past decade. They can come in and map out your current processes as well as your future processes. They lead workshops and guide companies through this transformation. I’m not affiliated with them, but I have utilized their services at multiple companies due to their level of experience and cost-effectiveness.

Good luck!

This is a bullseye for what we do at Valtech; helping reimaging customer experience. 

We can help you select the right tools, processes, people needed to bring the right IT strategy and roadmap to life.

Your cross-sell strategy should be data-driven. To answer your questions I would need to understand more about your business.
