If Crunchbase had your data

1. Look for Crunchbase’s own notice or letter: it should say what of yours was involved. Keep it.
2. Expect scams that use your details: calls, texts or emails pretending to be Crunchbase, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
