Expression 37 specialises in the long-term support and maintenance of business-critical ExpressionEngine and Craft CMS websites.

All work is handled personally by Karl. If your website matters to your business, you are in the right place.

A meaningful part of the work we do at Expression 37 involves inheriting Craft CMS sites that were built by developers or agencies who are no longer involved. The circumstances vary, but the practical challenge is always similar: a site you didn’t build, with code you didn’t write, and decisions that were never documented.
If your Craft CMS site connects to any external service, whether that’s Stripe for payments, HubSpot or Salesforce for CRM, or Mailchimp for email, you have a dependency that you probably don’t think about until it fails. Integrations break. Here’s why they fail and what to do about it.
Craft CMS has a strong but relatively specialised developer community. The difference between someone who has built seriously with Craft and someone who has touched it once or twice is meaningful. If your site runs on Craft and you need ongoing development or support, knowing what to look for matters.
