Thats because market penetration and revenue matters more than a few CSS animations

And enterprise sales.

Periscope has merged with Sisense: https://www.periscopedata.com/blog/periscope-data-sisense-be...

They are arguably essentially buying revenue to help their bottom line. Salesforce hopes to add $350-400M to their FY20 revenue

That's a pretty steep price to pay for a single-digit % increase in revenue. I view this more as filling a strategic hole. BI & Analytics from Salesforce are awful.

I don't know much about company account structures and finance dynamics, but that doesn't sound like much compared to the $15.7bn price?

Can you elaborate on the advantages of Periscope? I've used Tableau, but not Periscope. Browsing their site & marketing materials, it's not really clear to me how they're much different from Tableau.
