The verdict
Pick HubSpot if you are a small or growing team that values speed, a free starting point and a CRM you can actually run yourself: it is faster to learn, cheaper to start and the easier tool to recommend to most companies. Pick Salesforce if you are an enterprise with complex processes that need deep customisation, advanced forecasting and the largest app ecosystem in the category, and you have the admin resource to run it. Both are excellent CRMs; the decision is really about whether you are optimising for simplicity (HubSpot) or for power and scale (Salesforce).
