Our take

Calendly is a cloud-based scheduling service that is straightforward to use. It allows around 10 million customers per month to connect and make appointments based on their available times without having to send emails back and forth.

The platform offers four different plans - allowing individuals, small companies, and large enterprises alike to make use of these services. Calendly's growth to date been based mostly around a very organic strategy. Its invites become links to Calendly itself, so people who like it can, and do, start to use it.

There are a handful of competing products on the market, including offerings from Doodle and Microsoft, but Calendly's customer-friendly design has won it attention and allowed it to carve itself a space in the field. Impressive funding has contributed to the company's expansion, allowing it to capitalize on the increasing popularity of home and hybrid working.
