Luxembourg's Young Innovative Enterprise aid co-finances up to 70% of the forecast financing need a young company presents over a horizon of at most 3 years. The amount is calculated on the eligible costs of the project and cannot pass €1,000,000 per enterprise.
The company has to be small, unlisted, registered for less than 5 years and already trading: turnover of at least €40,000 in its last financial year or over the trailing year is one of the cumulative conditions, not an optional signal of traction.
Those parameters come from the guichet.public.lu conditions page for the scheme as it runs under the law of 6 June 2025, checked in August 2026. The same page attributes the support to the Ministry of the Economy.
The mechanic is a forward plan, not a refund
The instrument is often described as money that follows a fundraise. That is not what the conditions say. The published rate is a maximum co-financing rate of up to 70% of a forecast financing need presented over at most 3 years.
Private capital is built into the design, but as the other side of that forward plan rather than a receipt for a round already closed. What the company has to show is that private financing will complete the remainder of the need.
That distinction decides how a file reads. A plan built backwards out of costs already incurred is arguing for something the scheme is not shaped to co-finance, and no rewrite of the narrative changes the direction of travel. The ceiling is scoped just as tightly: calculated on the eligible costs of the project, applied per enterprise, so a second project later does not reset the headroom.
| Condition | What the published conditions require | Measured against | Where files come apart |
|---|---|---|---|
| Company age | registered for less than 5 years, small and unlisted, not built on another company's activity | the registration date | a restructure or a takeover of an existing activity quietly breaks the "not another company's business" limb |
| Turnover floor | at least €40,000 | the last financial year, or the trailing year | pre-revenue teams assume an innovation aid is a pre-revenue aid |
| R&D intensity | R&D spending of at least 15% of total operating expenses | at least one of the recent financial years the certificate examines | development salaries buried in an undifferentiated payroll line, so the share cannot be computed at all |
| Plan horizon | a financing need presented over at most 3 years | the plan you submit | plans written to the calendar of the raise instead of to the work |
| State share | up to 70% of the forecast need | the plan, with the balance privately financed | the private side is asserted rather than evidenced |
| Ceiling | €1,000,000 per enterprise | eligible project costs | reading the cap as per project |
The conditions are cumulative. There is no weighting and no compensating strength. A company that is brilliantly innovative but sits below the turnover floor is outside the scheme, and so is a company that clears every financial test without the innovation limb.
What "innovative" has to mean on paper
The innovation condition runs through a certificate issued by Luxinnovation. One of the criteria that certificate attests is the R&D-spend share: spending on R&D reaching at least 15% of total operating expenses in at least one of the recent financial years examined. It is not the only criterion.
Read that threshold carefully, because its shape is friendlier than it looks. It does not ask for sustained intensity across the company's whole life; the criterion is written around a single qualifying year inside the look-back. That works in favour of a company that spent heavily on development early and has since started selling.
Bookkeeping is where it is unforgiving. If engineering payroll, contractor invoices and infrastructure sit in one undifferentiated cost line, there is no R&D share to demonstrate and nothing to certify — the chart of accounts decides whether the test can be run at all. Splitting those lines in the year you incur the costs is far cheaper than reconstructing them afterwards.
The other half of the assessment is a judgement, not a formula: whether the company develops something new or substantially improves it, rather than distributing or reselling what already exists. Software with real engineering behind it, technically deep service models and engineering-led products sit comfortably in that space. A trading or agency business does not get there by rewriting how it describes itself.
The turnover floor is the condition founders discover late
Of every parameter above, the €40,000 turnover floor is the one that most often arrives as a surprise. It cuts against the mental model of a grant for young technical companies: however advanced the technology, a company that has not yet invoiced does not clear it.
Combine that with the age limit and the eligibility window is bounded on both sides. The company has to be trading enough to pass the floor, and still registered for less than 5 years when it applies. Teams that raise well before first revenue can burn a meaningful part of that window in a pre-commercial phase.
That is a scheduling fact worth knowing early, not a reason to rush a launch. Founders mapping the wider board of instruments, including the ones that do fund pre-revenue work, will find them in our Luxembourg startup funding reference.
How it sits beside the R&D project aid
The R&D project aid is a separate instrument with its own conditions page, its own application and its own limits. Its ceilings are expressed as base aid rates that vary by cost category and by company size; the small-enterprise column is the relevant one for anything that also fits the Young Innovative Enterprise profile.
| Cost category under the R&D project aid | Base aid rate for a small enterprise | Note |
|---|---|---|
| Industrial research | 60% | base rate; the same page states that uplifts may apply on top under conditions |
| Experimental development | 40% | base rate; the same page states that uplifts may apply on top under conditions |
| Any R&D project | — | for each project the gross aid cannot be below €1,000 for an SME |
Those base rates are what the page publishes before any uplift, so treat them as the floor of the maximum rather than the number a file will land on. Each instrument sets its own limits. Those limits do not, by themselves, settle how a single cost line is treated if it appears in both applications; that is decided on the specific costs in the file.
Common questions
These are the questions that follow once the parameters stop being abstract, and each is a place where a plausible-sounding assumption points the wrong way. Several turn on scope: what the ceiling attaches to, what the plan horizon actually governs. They tend to be misread in the same direction, towards something more generous than the conditions carry.
Does a pre-revenue startup qualify?
Not on the turnover condition. The published requirement is at least €40,000 of turnover in the last financial year or over the trailing year, and it sits among cumulative conditions, so it cannot be offset by strength elsewhere.
Is the ceiling per project or per company?
Per enterprise. The €1,000,000 maximum is expressed against the enterprise and calculated on the eligible costs of the project, so a later project does not open a fresh allocation.
Is the plan horizon the same as how long the money lasts?
No. What is published is the maximum horizon of the financing need you present, at most 3 years. It describes the shape of the plan, not a schedule of payments. An application written as though it guarantees a multi-year runway misreads the condition.
How much of the need do we have to cover ourselves?
Everything above the state's share. The co-financing rate reaches up to 70% of the forecast need, and the company has to demonstrate that private financing completes the rest. That demonstration is a documentation requirement about the balance of the plan, not a box to tick.
What to have in place before writing anything
The order matters more than the drafting, because several of these are slow and the later ones depend on the earlier ones.
- Confirm the company shape. Small, unlisted, registered for less than 5 years, and not carrying on another company's activity.
- Test the turnover floor against the last closed financial year or the trailing year, before anything else is invested in the file.
- Split the accounts so the R&D share is computable: engineering payroll, contractors and development infrastructure separated from general operating costs, so the 15% test can be evidenced rather than estimated.
- Pursue the Luxinnovation certificate early. It is a prerequisite with its own process, not an annex you attach at the end.
- Build the financing plan forwards across a horizon of at most 3 years, on work not yet done.
- Evidence the private side of the plan that covers the balance beyond the 70% state share, with documents rather than intentions.
- Cost the project properly against the €1,000,000 ceiling, so the eligible-cost base is defensible line by line.
The slow part is never the form. It is the financing plan and the cost annexes that have to stand behind it, which is the documentation work on a funding file rather than the pitch. Files that read well are the ones where the numbers in the plan reconcile to the numbers in the accounts without anyone having to explain the difference.
