What our clients say

“Working with Remarkable has been a high-trust relationship with shared accountability and open communication. They were on the ground with us at our main customer conference in Las Vegas with 24/7 support, and the launch went seamlessly. We can see significant improvements in time on page, reduction in bounce rate, and in conversion rates.”
“We selected Remarkable because they understood our vision for how the website and digital strategy can play a key role in enhancing the service we provide our clients and helping the company to continue our growth over the next few years.”
“We chose Remarkable for two reasons — the personalities we met during the pitch process, and the deliverables we’d seen them provide for other customers. Remarkable really understood our customer journey and spent a lot of time getting under the hood before the project started. When we saw the visual designs, not the wireframes but the actual impact of imagery and animation, it made a few of us in the room take a breath.”

Moving from Sitecore XP to SitecoreAI

  • Typically 20 to 30 weeks from kick-off to go-live, using our SitecoreAI Acceleration Suite
  • Lower total cost of ownership once you’re off XP infrastructure and upgrade cycles
  • AI built in. SitecoreAI includes Agentic Studio, where marketers build and run AI agents and multi-step Agentic Flows, starting with 20 pre-built agents
  • Light on your team. We can run it end to end, or alongside your team

Sitecore FAQs

What is Sitecore?

Sitecore is an enterprise digital experience platform (DXP) used by large organisations to manage content, personalise experiences and run multiple websites from one platform. It comes in two main forms: Sitecore XP, installed on your own infrastructure, and SitecoreAI (formerly XM Cloud), a SaaS platform.

What is SitecoreAI?

SitecoreAI, formerly XM Cloud, is Sitecore’s SaaS content management platform and the focus of its current investment. It is headless, so content can be delivered to any front end, and Sitecore manages the hosting and upgrades. It includes Agentic Studio, a workspace where marketers build and run AI agents and automated, multi-step Agentic Flows.

What is the latest version of Sitecore?

Sitecore 10.5, released in August 2026, is the latest version of the Sitecore Experience Platform. It and 10.4 are the only versions in Mainstream Support (10.4 until December 2027). Versions 10.0 to 10.3 are in Extended Support, where security fixes have been a separately paid arrangement since June 2026, and 9.3 and earlier no longer receive patches at all. SitecoreAI (formerly XM Cloud) is Sitecore’s SaaS platform and the focus of its current investment.

If you are on an earlier version of Sitecore XP, our Sitecore Exposure Review will confirm exactly which version you are running, what support it still has, and the most cost-effective route forward.

Should I upgrade Sitecore XP or move to SitecoreAI?

It depends on your version, your licence renewal date, how customised your build is and what you need the platform to do next. For some organisations an XP upgrade is the cheaper route; for others it costs nearly as much as a migration. The Sitecore Exposure Review compares both and costs them for you.

How long does a Sitecore XP to SitecoreAI migration take?

A typical migration from Sitecore XP to SitecoreAI takes 20 to 30 weeks, depending on the number of sites, integrations and how much of the existing build carries over. Accelerators shorten this by reusing proven components rather than rebuilding them.

How do I choose a Sitecore partner?

Check their partner tier, the experience of the people who will work on your account, whether they have delivered upgrades and migrations from your version, and whether they support you after go-live. Remarkable is a Sitecore Platinum Partner whose team has won more than 30 Sitecore MVP awards over the years.

Who is Sitecore suitable for?

Sitecore suits mid-to-large organisations that need complex workflows, personalisation and the ability to manage multiple sites, brands or languages from one platform.

Does Sitecore integrate with third-party platforms?

Yes. Sitecore’s open, API-first architecture integrates with CRMs, analytics tools, commerce platforms and marketing automation.

Is your Sitecore estate earning its keep?

Start with the Sitecore Exposure Review: your version, security and licence position, and costed options, in two weeks for £4,950. If the board is asking about the whole estate across Sitecore, CRM and data, the Digital Estate Diagnostic is the better fit.
