- ✓Full control over your marketing automation without feature gating
- ✓No contact-tier pricing that penalizes database growth
- ✓Self-hosted CRM with no limits on contacts or properties
What you give up

- △No HubSpot CMS with CRM-powered personalization
- △No unified reporting across marketing, sales, and service data
Switching Cost
HubSpot's lock-in is the unified platform. Your contacts and deals export as CSV, but the marketing automation workflows, email templates, landing pages, and reporting dashboards are deeply interconnected. Teams using only CRM features can migrate in a few days. Teams running full marketing automation (email sequences, lead scoring, ad tracking) should budget 3-4 weeks to replicate across multiple tools. The hidden cost is losing the unified view: HubSpot shows marketing touches, sales activity, and support tickets for each contact in one timeline, and you'll need integrations to rebuild that.

Building Blocks
HubSpot is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
