We've spent the last few months building out the crawling, parsing, indexing and categorization capabilities on the site, but most of the data displayed for vendors was just a one time snapshot - not reflecting any momentum as leaders increase their market share and challengers enter the space.
Today, we launched a super rough version of Trended metrics over time. Right now, it tracks social followers, inbound links and website traffic over time for over 1500 martech companies, with just a few data points so far.
These stats will update weekly for some vendors and monthly for others depending on their rankings (higher ranked vendors see more significant changes to these metrics on a frequent basis, so they'll get updated more frequently).

*Note: You'll need to sign up for a free account to see the metrics charts at the bottom of the vendor pages, they aren't publicly viewable yet (still pretty ugly).
