Hello, you received a reply in another comment about adding more time tracking and reporting to Trello.

This goes right to the core of all of the issues/conflicts bundled into this acquisition from UX details up through to target users and culture clash.

Time tracking is a manager-oriented feature, not a producer-oriented feature. The users producing the work usually resent things like fine grained time tracking and comparitive producer reporting because it distracts from actual work, treats creative or complex processes as though they are part of an assembly line, encourages micro-management, pits quality against time, and emphasizes wage servitude.

Managers can use Trello to stress out their employees too, but not to the extent that JIRA-ish tools enable.

The problem is you are selling to managers who love to micromanage their employees and have nothing better to do than fiddle with configuration, reports, or have meetings with the people they hired to do that.

This is why developers who are smart will probably try to protect themselves by pre-emptively replacing Trello with one of the dozens of free or inexpensive clones before you can start corporatizing it and their company.

Be it for the general use cases or for the software team collaboration, time tracking and reporting features are always useful. As a user of both JIRA & Trello, I hope Trello soon gets all the time tracking and reporting love that JIRA team could add. Congrats and good luck!
