I'd be extremely surprised if you cannot manage to find one solution that fits your agency's needs from the plethora of SaaS products in those categories.
I'd be extremely surprised if they can. Just because there are a lot of options, doesn't mean there's any good ones. Tons of nearly identical, virtually featureless products does not make it easier to find one that actually does the job.
I COMPLETELY agree with this statement. We have been looking around for about a month now, and it's been really hard to distinguish them apart. It's been equally as difficult to find a product that has everything we need.
From personal experience, most of the issues of PM/Scrum/Kanban/Agile software is employee adoption rather than lack of features. As to CRM software, I can't say.
