A 40,000-seat migration delivered six weeks ahead of a renewal deadline

A Fortune 500 customer was three weeks from renewal, halfway through a migration, and had lost the internal engineer who owned it. Nobody on our side wanted to touch it because the contract was already counted as lost.

• Rebuilt the migration plan from scratch in four days, working directly from the customer’s own ticket history.
• Ran a written daily standup across three time zones so no one was ever waiting on a call to make progress.
• Escalated two genuine product bugs to engineering with reproductions attached — both shipped in the next release.
• Left behind a 40-page runbook the customer’s new admin still uses today.
