When did SalesLoft buy drift?

Can you provide me with some more context or details about the SalesLoft and Drift acquisition? I'm curious to know exactly when SalesLoft made the decision to acquire Drift, as well as any notable events or milestones that may have led up to this decision. Additionally, I'm also interested in learning about the terms of the acquisition, such as the price paid and any potential strategic benefits or synergies that SalesLoft may have been seeking to gain through this acquisition.
