A product is more than access to a model. Someone has to find the right information, understand the answer, decide what to do and recover when a result is incomplete. We design that entire experience: the interface, the underlying workflow and the operational responsibilities around it.
We first establish whether the requirement calls for a new product, an extension to an existing application or a smaller automation. Custom development earns its place when the experience, business logic or information context needs a level of control that existing tools cannot provide economically.
