No, it isn't too late. Zoom Video has lower barrier of entry for business to conduct webinar or video conferencing.
In this climate of COVID 19, the use case for video conferencing will soon eliminate the need to rent a place to conduct meetings or seminars.
Although live meetings and seminars are still preferred but look at the costs of the following:
1. Cost to rent a place and logistics
2. Cost to distribute printed materials
3. Cost to hire manpower (ushers, security)
This can be substituted while businesses are forced to digitalised by using Video Conferencing at lower cost.
The reason while this is still a buy is because it takes time for businesses to adopt and change their work processes into conducting their meetings and seminars via Video conferencing, with HUGE COST SAVINGS and elimination of time and cost needed for travelling.
