MIG MatInvestGroup operates through miginvestgr.tiiny.site and promotes investment management services.
In this case, there is no need to rely only on anonymous reviews. The exact website has already appeared on an official financial regulator blacklist.
AMF blacklisted the exact website
France’s Autorité des Marchés Financiers added miginvestgr.tiiny.site to its blacklist on June 25, 2026.
The regulator categorises it as an “Other unauthorised entity.”
This is an important distinction. The warning concerns the exact website, not merely another company with a similar name.
For potential investors, this should carry considerably more weight than promotional statements published by MIG itself.
MIG promises more than 50% per month
The investment presentation contains unusually aggressive numbers.
MIG MatInvestGroup has advertised more than 50% monthly returns while also claiming 100% capital protection.
Those two promises should immediately raise questions.
Investment markets involve risk. An advertised return exceeding 50% every month combined with a guarantee of the original capital is not a normal investment-management proposition.
The website also presents the business as operating since 2017.
However, independently verifying that claimed history is difficult.
Why is an investment manager using tiiny.site?
Another unusual detail is the website itself.
MIG does not use a conventional corporate domain. Its investment presentation is hosted at miginvestgr.tiiny.site.
Tiiny is a general-purpose website hosting service. Using it does not prove misconduct.
However, it is an unusual choice for a company supposedly managing client investments and offering extremely high monthly returns.
A professional investment manager should also make its legal entity and regulatory authorisation easy to verify.
Who is behind MIG MatInvestGroup?
Published copies of the website identify “Mathieu Sevellec” as CEO.
The project is also referred to as MIG MatInvestGroup.
However, independent investigations have struggled to connect this presentation with a regulated investment company.
More importantly, the AMF has already classified the exact website as an unauthorised entity.
Therefore, users should not assume that a company name, CEO photograph or professional presentation establishes financial authorisation.
Miginvestgr reviews are extremely limited
There is very little genuine independent feedback about the platform.
Trustpilot currently contains only two reviews for the exact website. One of them is a one-star complaint posted in April 2026.
Such a tiny sample cannot establish what happened to every investor.
The AMF warning is much more significant than the review score.
The displayed profit is not the important number
With promised returns exceeding 50% monthly, an account balance can theoretically grow very quickly.
The real question is whether that balance can actually be withdrawn.
If money has already been deposited, do not increase the investment simply because the account shows substantial profit.
Be particularly cautious if a withdrawal produces demands for:
- tax or commission paid separately;
- insurance or security deposits;
- account verification payments;
- AML or compliance charges;
- another investment before funds are released.
Each additional payment can increase the eventual loss.
What should MIG clients do?
If a withdrawal is already unresolved, stop increasing the deposit until the situation is independently checked.
Save the original miginvestgr.tiiny.site page, investment offer and account screenshots.
Keep WhatsApp, Telegram, email and other conversations with representatives. Preserve the name and payment details of every recipient.
For cryptocurrency transfers, save wallet addresses and transaction hashes.
Most importantly, keep a copy of the regulatory warning. The French AMF has already listed the exact miginvestgr.tiiny.site address as an unauthorised entity.
Combined with promises exceeding 50% monthly returns and 100% capital protection, this gives potential investors substantial reason to avoid sending additional funds.
