If you’d like to use a strong captcha approach without using a competitor you might want to check out http://funcaptcha.com (I have no affiliation, have heard good things and been presented it on a couple of sites)

The "Book Demo" button and "read white paper" button seem to be broken, which does not inspire much confidence. The first button just takes me to the bottom of the page while the second button does nothing.

Not sure if this is the same, but I once came across a website with a captcha where you had to rotate a dog so it stood upright, but it was lagging so bad that it would skip several frames, making it impossible to time the angle correctly. After several minutes of trying I gave up and went to a different website with an inferior service, but which did not waste my time.

Both buttons work for me on mobile. Can't be sure, but that page looks like a JavaScript heavy "single page app" type situation, so if your JS is turned off that might explain things.

Incidentally, both links just pop up a sign-up form.

The link redirects to some other site now.

The site requires you to whitelist marketo.com which is blocked on uMatrix as it's a marketing company.

Ticketmaster uses one like this, with various animals.
