What the industry is saying about Kastio

Claude Boudreau

President, Cybermediacom Inc

As a professional webcasting service provider we were considering building our own webcasting platform to better serve our clients. Before jumping in, we were evaluating some of the newer webcasting platforms on the market. It was in this evaluation period that we found Kastio. All we can say is 'wow'. They've built everything we need (and more) in their platform and it's a fraction of the cost to us building our own. Now we're running our biggest webcasts on Kastio and loving every minute of it.

Andrew Irving

Owner & Webcast Producer, IrvTech

Kastio's platform gives me the ability to produce interactive webcasts with enterprise-grade features. The platform lets me deliver on my clients' expectations for a fraction of the cost of previous previous providers. Great work, Eventstream!

Chris Kamarianakis

Executive Director, Protect Your Boundaries Inc

Kastio's integration to our e-commerce system enabled us to seamlessly sell seats to our webcast.  Their execution of the webcast during the event was flawless, garnering a 9.5 out of 10 rating from an audience.
