“We called Imagine Clany Eco when another company cancelled on us last minute for our move-out cleaning. Clany Eco was able to book us and make it out in 2 hours and did an amazing job. We even got our deposit back.”
I appreciate the focus on helping regional banks specifically. Often, the advice out there is geared towards larger institutions and doesn’t address the specific constraints and opportunities that regional banks face. I think exploring strategies like M&A to achieve operational scale and offset regulatory compliance costs is critical for these banks1. Also, as mentioned in another article, developing or expanding niche capabilities to open up new opportunities could be a game-changer.
