Engineering the Business goes under the hood. Paul Maxwell and Buzco Stanislav cover the HubSpot API surface, integration architecture, UI extensions, data models, and middleware — the technical decisions that determine whether a GTM system is durable or disposable. Written for engineers and the operators who work with them.
