Pros
HubSpot's training is top-notch, both their inbound marketing training as well as their on-going sales coaching. From a lead perspective, HubSpot generates 50K to 60K leads per month which means no cold-calling for the VAR Channel Account Managers. Further, their marketing team creates really great, helpful content which people love, so 99% of the calls you have are with people who already love the brand and product. The managers really care about your development and don't micro-manage. They let you run your own business. They put an emphasis and teaching, coaching, and learning. Further, they pay very well. I went from making $55K/year at my last sales job to $184K in my first year with HubSpot.
Cons
The most difficult part of the job is time-management. There are a lot of unqualified leads that come through and it's your job to disqualify prospects who are not going to make good re-sellers. You must quickly assess if HubSpot's Partner Program can help them or not, if not, you must break up with them. In your first year as a VAR Channel account manager, you must work very hard to set yourself up for year 2. This means long hours at the office for your first 6-9 months. However, the payoff is worth the wait.
