Both HubSpot and Salesforce offer a wide range of apps and integrations, but Salesforce's App Exchange offers more volume, while HubSpot's App Marketplace is more curated and user-friendly. Both platforms have robust AI features, with Salesforce's Einstein being more customizable, but HubSpot's AI is easier to use. Salesforce has an edge in customization, with access to custom coding and a wider range of standalone apps. However, HubSpot's pricing structure is more accessible, especially for smaller teams, with a free tier available. Ultimately, the choice between HubSpot and Salesforce depends on your team's specific needs, with both platforms offering similar features at different price points.
