Cal.com

Here is Cal.com in plain terms. Scheduling infrastructure for absolutely everyone. Put simply, it is about building software for you when nothing off the shelf fits.

The natural audience is companies with a specific process to automate. They are a small team, 11 to 50 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Cal.com is based in San Francisco, California. You can read more at cal.com.
