HubSpot

All-in-one platform bundling CRM, marketing automation, sales, customer service, and CMS into a single contact database — an alternative to stitching Salesforce + Marketo + Zendesk + WordPress together. Best-in-class permanent free tier (not just a trial) makes it the default choice for SMB and mid-market teams consolidating their tech stack. Pioneered the inbound-marketing methodology and acquired Clearbit in 2023 for built-in data enrichment. Notable pricing quirk: charges per marketing contact rather than per seat, so bills scale with database size rather than headcount — which can bite fast-growing lists at renewal.
