Skype for Business

Skype for Business is available as part of Microsoft’s Office 365
package, which comes with the full Office suite (Word, Excel,
Powerpoint, etc.). Skype for Business features all of the stuff you’d
expect from a product with Skype in the name: instant messaging, audio
calls, and video chat. But it also has features businesses need to
keep safe and compliant, like local hosting and permission control.

As part of the Office suite, it also deeply integrates with your
calendar and contacts from Outlook, as well as documents from Word and
Excel. Are you an existing Microsoft customer? You probably already
have this! If not, it’ll set you back $8.25/user/month.

along with the option to record and share meetings. It also makes it
easy to integrate video from almost any platform available, giving
your startup the look and feel of a top-tier business without the
top-tier cost.

Join.me

Join.me is one of the best options when it comes to connecting and
collaborating with your team. This tool gives startups the ability to
share audio, video, whiteboard, live chat, and enable users to share
control over their screen. The rich range of annotation and remote

Join.me can be used for free, but to lift the participant cap to 5 and
host unlimited meetings, you’ll have to buy a plan starting at
$9/user/month.
