The short answer
Venture capital firm Insight Partners experienced a data breach in January 2025 where hackers stole personal information of current and former employees and the firm's limited partners. The company has completed notifying affected individuals about the compromise of their sensitive data.
If you have an account with Insight Partners, assume the exposed details are circulating. The practical risk today is rarely the leak itself — it is the calls and messages that use those details to sound legitimate.
What we have on file
Every entry below is a catalogued record with its original source. We do not paraphrase beyond what the source reports.
What to do
- Change the password anywhere you reused itThe exposure matters most when the same password protects your email, because email is how everything else gets reset.
- Treat every call and text about this breach as a scam until proven otherwiseNo company will ask you for a one-time code, a PIN or a password. Hang up and call the number printed on your card.
- Read your statements for the next three monthsCard fraud usually starts with a small test charge. Catching that one is what stops the large one.
- Give your email account a password nothing else usesIt is the account that can reset all the others, so it is the one worth protecting first.
Questions people ask
Was my data in the Insight Partners breach?
Having an account alone does not confirm exposure. The reliable check is whether your email address appears in the leaked datasets in circulation — that takes seconds and does not require your password.
Is it too late to do anything?
No. Leaked personal details do not expire, and neither does the defence: a unique password on your email, and a fraud alert on your credit file, still work years later.
Will Insight Partners contact me?
They may. But scammers contact people too, using exactly these breach details to sound convincing. Never act on an inbound call or text — call back on a number you already had.
