I couldn't find it in Google either. Found two other tech companies using Beam in their product name (not to mention Erlang) which is only a minor issue. And the site doesn't mention browser anywhere on the homepage (SEO?).

Even the footer and "Join the beta" CTA only loads after the generic slogan.

Hopefully this isn't an indication of their design and web dev sensibilities. Which are critical for browser development. This is some basic work you do before doing PR rounds.

Edit: found a blog post with their 'vision', with content that would work better as homepage https://getonbeam.medium.com/beam-bright-paper-1ca4ae41ae0b
