Check that the issue is actually resolved, expectations are clear and the customer has had time to experience the improvement. A closed ticket is not proof that the relationship is healthy.
Do not make assistance or compensation conditional on an introduction. A thank-you from the customer should not be silently interpreted as permission to ask for their network.
Consider relevance, relationship preferences and current customer circumstances. Research a specific suitable target and confirm the connection before asking.
Capture the cause and follow-through in the customer process. Avoid publishing a universal claim that customers become more loyal after a failure.
Orbb's Referral Agent can support an agreed introduction workflow, but customer success should retain judgement over suitability and timing. Automation should not turn a service recovery event into an indiscriminate commercial request.
