If you are raising a Luxembourg fund (whether a RAIF, a SIF, or a SICAR), you will run into the "well-informed investor" requirement within the first week of structuring discussions. It is one of Luxembourg's defining features as a fund domicile, and it creates both a quality filter and a practical hurdle that first-time managers need to plan around.
I spend a lot of time explaining this to emerging GPs, because the rule is simultaneously stricter than what they expect (EUR 125,000 is a real barrier for some investors) and more flexible than they assume (there is a certification pathway that opens the door wider than the headline number suggests).
What the law says
The well-informed investor concept appears in three pieces of Luxembourg legislation: Article 2 of the SIF Law (Law of 13 February 2007) [1], Article 2 of the SICAR Law (Law of 15 June 2004) [2], and Article 3 of the RAIF Law (Law of 23 July 2016) [3]. All three use essentially the same definition.
A well-informed investor is any person who falls into one of the following categories:
- Institutional investors. Banks, insurance companies, pension funds, sovereign wealth funds, and similar entities. No minimum investment required.
- Professional investors. Persons qualifying as professional clients under MiFID II (Directive 2014/65/EU) [4]. This includes large corporates meeting the balance sheet, turnover, and own funds thresholds, as well as entities authorised or regulated to operate in financial markets.
- Other investors who either (a) invest a minimum of EUR 125,000, or (b) have obtained a written assessment from a credit institution, investment firm, or management company certifying that they have the expertise, experience, and knowledge to adequately appraise an investment in the fund [3].
The third category is where most of the practical questions arise. It is the gateway for high-net-worth individuals, family offices that do not hold a MiFID licence, and angel investors who want to participate in a Luxembourg fund.
The EUR 125,000 minimum in practice
The EUR 125,000 threshold applies per investor per fund. It is not a net worth test; it is the actual amount of capital that the investor commits. For a first-time venture capital manager trying to aggregate commitments from business angels, corporate executives, or smaller family offices, this can be a real constraint.
Consider a typical scenario: you are raising a EUR 20 million Fund I, and you have 15 prospective investors who want to commit EUR 50,000 to EUR 100,000 each. Under Luxembourg law, none of them qualify as well-informed investors through the minimum investment route. You either need to get each of them certified, find a way to aggregate them into a feeder vehicle, or accept that Luxembourg is not the right domicile for that part of your capital base.
By comparison, many jurisdictions set lower minimums or none at all. The UK's RVECA regime requires EUR 100,000 from non-professional investors. Germany's sub-threshold AIFM registration has no statutory minimum for professional investors, though the BaFin expects fund documents to set appropriate minimums. Jersey, Guernsey, and the Cayman Islands have their own standards that can be lower depending on the fund structure.
The certification pathway
The alternative to the EUR 125,000 minimum is certification. An investor who cannot or does not want to commit EUR 125,000 can participate if a credit institution (bank), an investment firm, or a management company provides a written assessment confirming the investor's expertise, experience, and knowledge [3].
The process is more flexible than it sounds, but it has operational requirements that managers need to plan for:
- Who can certify. The certifying entity must be a regulated institution: a bank, an investment firm authorised under MiFID, or an AIFM or UCITS management company. Your fund administrator or legal counsel cannot provide this certification.
- What the certification covers. The assessment must confirm that the investor has sufficient expertise and knowledge to understand the risks of the investment. It is not a tick-box exercise, and the certifying institution takes on liability for the assessment.
- Timing. The certification must be obtained before the investor subscribes. You cannot accept a commitment and get the certification retroactively.
- Documentation. The certification letter must be included in the investor's subscription file. Your fund administrator will check for it as part of the onboarding process.
In practice, investors who have a private banking relationship can often obtain certification from their bank relatively easily. The bank already knows the client's financial profile, investment history, and sophistication level. For investors who do not have an existing relationship with a certifying institution, the process takes longer and may require the investor to open a custody or banking relationship first.
How this compares to MiFID II professional client categories
A common misconception is that Luxembourg's well-informed investor standard is the same as the MiFID II professional client classification. It is not. MiFID II defines professional clients in Annex II of the directive [4], and that definition is one pathway to well-informed investor status, but the well-informed investor concept is broader.
Under MiFID II, a retail client can be "opted up" to professional status if they meet at least two of three criteria: sufficient transaction frequency, a portfolio above EUR 500,000, or relevant professional experience [4]. This is a separate process from Luxembourg's well-informed investor certification and is handled by the investment firm providing the service.
In practice, some investors may qualify as professional clients under MiFID II but not meet the EUR 125,000 minimum for Luxembourg. Others may be willing to commit EUR 125,000 but would not qualify as professional under MiFID II. The two regimes overlap but are not identical, and you need to track which pathway each investor uses.
Structuring around the threshold
Emerging managers with a mix of larger and smaller investors often use a feeder fund to aggregate smaller commitments. A feeder vehicle, typically domiciled in a jurisdiction with a lower or no minimum investment threshold, can accept smaller ticket sizes and then invest as a single well-informed investor into the Luxembourg master fund. The feeder's commitment to the master exceeds EUR 125,000, satisfying the requirement.
We see this pattern frequently with US-based angel investors who want exposure to a European venture capital fund but cannot or do not want to commit EUR 125,000 individually. A Delaware LP or LLC acts as the feeder, the GP raises capital into the feeder at lower minimums, and the feeder invests into the Luxembourg fund as a single institutional or professional investor.
The trade-off is cost. Running a feeder adds legal, administrative, and tax filing obligations. For a small fund, the economics need to justify the additional structure. If the aggregate capital from smaller investors is material (say EUR 2 million or more), the feeder usually pays for itself. Below that, it may be simpler to either set a higher minimum for the Luxembourg fund or use the certification pathway for qualified investors.
Nominee structures and indirect holdings
Nominee or pooling structures offer another route. A private bank or wealth manager acts as the registered holder of fund units on behalf of multiple underlying clients. The nominee appears as a single well-informed investor in the fund's register, while the bank manages the allocation to its underlying clients separately.
Common in private banking, the approach can work well for emerging managers with LP introductions from wealth managers. The key issue is transparency: under Luxembourg AML requirements, the fund and its administrator must be able to identify the ultimate beneficial owners behind nominee holdings. The nominee structure does not relieve you of your KYC obligations; it just shifts some of the administrative burden to the nominee institution.
Nominee structures can obscure your LP relationships, and that concern is valid. If investor relations matter to you (and they should), make sure you have a direct line to the underlying investors even if the legal subscription goes through a nominee. Your fund documents should address this by requiring the nominee to disclose the identity and contact details of beneficial owners above a certain threshold.
Compliance and ongoing monitoring
The well-informed investor check is not just a one-time gate at subscription. Your fund documents should specify the eligibility criteria, and your administrator should verify compliance at each subsequent closing if you are running a multi-close fund. If an investor's status changes (for example, a professional investor loses its MiFID classification), there are questions about whether they can participate in follow-on closings.
The CSSF has not published detailed guidance on ongoing monitoring of investor status for SIFs, SICARs, or RAIFs, but best practice is to include representations in the subscription agreement that require investors to notify the fund if their status changes, and to re-verify at each additional closing.
Common mistakes
In my experience, the three most common mistakes managers make with the well-informed investor standard are:
- Assuming all family offices qualify automatically. Many single-family offices are not regulated entities and do not hold MiFID licences. Unless they invest EUR 125,000 or obtain certification, they do not qualify. Do not assume; check.
- Leaving certification to the last minute. Getting a bank to issue a certification letter takes time. If your investor does not have an existing relationship with a certifying institution, budget at least four to six weeks for the process. If you are trying to close the fund next week, it is too late.
- Ignoring the transfer scenario. If an LP transfers their fund interest to a new holder on the secondary market, the new holder must also qualify as a well-informed investor. Your LPA should address this by requiring GP consent for transfers and making well-informed investor status a condition of the transfer.
