In 2017, I started as a HubSpot consultant, advising go-to-market teams on their strategies and how to implement them with HubSpot software. Early on, HubSpot certifications were the critical part of my learning. After I was up-to-speed, certifications helped freshen and broaden my working knowledge. For example, before we launched Service Hub, I didn't know how to talk "customer service." The service strategy and software certifications helped me start on that learning curve. Ditto revenue operations.
The two HubSpot architecture certifications are for technical people what those classic marketing, sales, and service software certifications are for go-to-market consultants: a required 101 to working in this environment.
