-We build business systems, internal tools and integrations to fit the way your
-organisation already works — and then we keep them running. Most of our
-engagements turn into long relationships rather than one-off deliveries.
+We engineer bespoke business systems, internal productivity utilities, and robust system
+integrations shaped precisely around your organisation's current workflows — continuing to support
+and refine them long after go-live. Our engagements consistently evolve into long-term technology
+partnerships rather than transactional, one-off deliveries.
 
-## Where We Fit
+## Who We Are Best Suited For
 
-We are not the right choice for every project, and it saves everybody time to
-say so before we start.

-### A good fit
-
-- **The business logic is the hard part.** You need something shaped around how
-  you actually operate, not a template with your logo dropped into it.
-- **You have no in-house engineering team**, or the one you have is committed
-  elsewhere.
-- **You care what happens after launch.** We would rather maintain a system for
-  years than hand it over and disappear.
+- **Complex business logic is the primary challenge**: You require a dedicated system tailored 
+  around distinct, non-standard workflows, rather than generic templates that force your
+  organisation to compromise.
+- **Requiring dependable full-stack technical capacity**: You have not yet established an in-house
+  engineering team, or existing technical resources are fully committed and require autonomous,
+  end-to-end delivery.
+- **Valuing long-term stability and continuous evolution**: Deployment is merely day one. You prefer
+  an experienced technical team that understands your systems deeply and remains available for 
+  sustained maintenance and agile iterations.
