Calendly
The modern scheduling platform that makes finding time easy.
What it does
Automates meeting scheduling by sharing a simple availability link. Syncs with Google, Outlook, and iCloud calendars to prevent double-booking. Features 'Round Robin' and 'Collective' scheduling for teams. Automates meeting reminders and follow-ups via email and SMS. Integrates with payment processors to collect fees during booking.
Why it works
Efficiency: Removes the friction of manual scheduling, saving users an average of 4 hours per week. Network Effect: Every time a user sends a link, a non-user is exposed to the product (viral growth). Personalization: Allows for granular control over buffer times, daily limits, and meeting durations. Enterprise Ready: Offers robust security, SSO, and team management for large organizations.

Founder story
Founded in 2013 by Tope Awotona in Atlanta. Tope, a former sales rep, spent his life savings and 401(k) to build the first version after being frustrated by existing scheduling tools. He focused on a 'product-led' approach that prioritizes user experience, eventually scaling it into a global unicorn.
