Calendar

What Calendar does

Calendar (Calendar.com Inc.) is a Palo Alto-based SaaS company, founded in 2017, that operates a unified scheduling and time-management platform targeting individuals, solopreneurs, small businesses, and enterprise teams. The product aggregates Google, Outlook, iCloud, Exchange, and CalDAV calendars into a single color-coded view, layers AI-driven "Smart Scheduling" that learns user habits and energy levels to recommend meeting times, and adds team features including round-robin booking, fair lead distribution, shared availability, focus-time tracking, and a visual automation workflow builder. The product surface spans six modules: Connected Calendars, Scheduling, Contacts, Team Productivity, Analytics, and Automation, with native integrations to Salesforce, HubSpot, Slack, Stripe, Zapier, Zoom, Microsoft Teams, Google Meet, and GoTo Meeting. The business runs a hybrid go-to-market: a product-led growth funnel anchored by a 14-day free trial with no credit card required, self-serve signup via Google, Microsoft, Apple, or email, and apps on iOS, Android, and web, supplemented by a direct sales motion for the Enterprise tier (SSO, SCIM, audit logs, dedicated success teams). Revenue is generated via tiered subscription (Individual, Entrepreneur, Small Business, Enterprise), with PCI DSS Level 1 certification enabling payment collection at booking. The company has 11-50 employees, claims 80,000+ business customers, holds a 4.8/5 G2 rating, acquired TimeBridge in 2019, and has raised only $270,835 in disclosed funding (January 2022), indicating a lean, largely bootstrapped operating profile.
