The AMF warning identifies the following information:

Listed name: prénom.nom@sigma-invest.co

Blacklist category: Usurpation

Date of publication: 25/06/2026

Regulator: Autorité des Marchés Financiers

The entry appears to relate to the unauthorised use of a Sigma InvestCo-style identity, with the email format prénom.nom@sigma-invest.co being specifically listed by the regulator.

Why Identity Usurpation Matters

Identity usurpation occurs when unauthorised individuals or entities use names, email formats, branding, or corporate references that may cause investors to believe they are dealing with a legitimate financial business.

This type of misconduct can be especially dangerous because victims may lower their guard when the communication appears connected to a recognised or professional-sounding organisation.

Investors should always verify the exact email address, domain name, and official contact details before responding to investment offers.

How Investors Can Protect Themselves

Before engaging with any financial offer, investors should:

• Verify the firm through official regulator databases.
• Check whether the domain and email address match official company records.
• Be cautious of unsolicited investment offers.
• Avoid sending funds based only on email communication.
• Review public warnings published by regulators such as the AMF and IOSCO.

Additional research through Trustpilot, Reddit, and FastBull may also help investors compare public experiences and learn more about common investment-fraud tactics.

What To Do If You Were Contacted

If you received an investment offer from an address using sigma-invest.co or a similar Sigma InvestCo-style identity:

• Stop communication until the sender is independently verified.
• Save emails, documents, and payment instructions.
• Do not send additional funds.
• Preserve transaction records if money has already been transferred.
• Compare the contact details against official regulator warnings.

Final Observation

The AMF blacklist entry for prénom.nom@sigma-invest.co highlights how impersonation-style financial scams can rely on professional-looking email addresses rather than obvious fake websites.

For investors, the safest approach is to verify every investment contact independently before sharing personal information or transferring funds.
