Beamer is really solving my need of communicating my new features to my customers. Previously I've relied on e-mails which not only have a low open rate but take me too much time to design and send. With Beamer I'm saving tons of time on this and putting those new features right on my customers's noses which is great for my to show my SAAS customers our progression.
