LeanCall.io was built with a focus on small teams, startups and small business. You can dial in and leave it on all day and talk to remote team members if you like, or just conduct regular conference calls. Marketing speak aside, we have extra capacity on a high quality bridge/switch that we use for our other products and I wanted to spin up something else. The app is supported by the same team maintaining our other products with 4.5 million registered users, 2+ million monthly uniques, multiple sites and a total of 8 years in business so it's not a fly by night sort of thing.
First: Signup is insanely simple, just an email. We send you your dial-in info and an email you can forward to people so they can connect too.
Second: No annoying hold music.
Third: Login gets you a few more free features like presentation mode and leader (host) mode.
Fourth: It is just meant to be super simple.
