The stratospheric rise of Zoom has caused the market for conferencing software as a service (SaaS) to hit more than $800 million in the first quarter of this year, according to Synergy Research.

The figures are divided into two camps – and reveal another facet of the enterprise IT software market being cannibalised by cloud. Traditional web and video conferencing revenues, led by Cisco, LogMeIn and Microsoft, have declined 1% year on year, while the smaller subset, which Synergy describes as video as a service (VaaS), rose 80% from this time last year.

VaaS market share has risen steadily, from 15% of the total conferencing SaaS market at the end of 2017, to 20% a year later, and 27% a year after that. According to Zoom’s most recent financial results, the company has seen a 169% year over year growth, with first quarter total revenues of $328.2m.

The Covid-19 pandemic has naturally seen the rise of video and web conferencing more generally, but industry analysts have pointed to several reasons why Zoom became the darling of the space.

Jeremy Duke, founder and chief analyst at Synergy Research, noted the strides Zoom has made but also acknowledged the sands of time were shifting.

“The market was already heading in a direction that was favourable to VaaS generally and to Zoom specifically, but the impact of Covid-19 has turbo-charged that trend,” said Duke. “Previously, VaaS was starting to gain traction in the mid-market and with large enterprises, helping to expand the overall market opportunity. Now we are suddenly seeing VaaS usage blossoming across the board.
