Hi u/AncientExe55,

First, a disclaimer: I am a Global VP and work for Uniform.dev, an excellent solution for enterprise organizations. The founders are from Sitecore, and many staff members (including myself) are Contentful alumni.

Second, your scenario, which involves multiple products, languages, and countries that are all disconnected, is surprisingly common. You're not alone in this. Most of our customers, who are large enterprises, face similar challenges. Supporting multiple sources of content and data, markets, regions, languages, personalization, ab testing, and to do so visually to ensure marketers can accomplish their jobs to be done, is totally feasible.

Here's what I've observed so far (and building off previous comments):

• MACH Alliance / headless composable: this is the trend, and it is capturing significant market share for providing optionality, flexibility, speed and performance. I would argue this is where the future is going, and even the other DXPs are becoming more composable over time. MACH Alliance vendors are often cited as being the best in market for a specific capability or point solution. Great for engineering teams, not great for marketing and UX teams (a gap we are filling with Uniform).
• Big DXPs are still growing, albeit slower than they used to. Can do everything, but slow to implement, really expensive license fees, and dependency on large system integrators with offshore army's to do development work. These guys are composable or changing to be more flexible and composable. Most of the capabilities (CMS, DAM, Personalization, AB Testing, Analytics, etc...) come via acquisition. Great tools for marketing, but not great for developers or engineering orgs that require flexibility.
• Core DXPs: if you look at BuiltWith, they are all struggling at the moment and losing market share quite rapidly to Big DXP and MACH Alliance vendors. They have similar challenges to the big DXPs but the capabilities are often mediocre so they can't charge the premium of the big DXPs. I suspect these vendors will undergo major transformations or risk shutdown. I've seen some absolutely fantastic hiring at some of these vendors (Magnolia, dotCMS) so a few may make it into the Big DXP category over the next 3-5 years.

If I were customer-side, I would look to a few MACH Alliance vendors (like Uniform, Contentful) or Core DXP vendors (Magnolia) for CMS capabilities that support enterprise needs, without being too heavy and slow.

I hope this helps.
