EIC STEP Scale Up Defence call 2026: why it is not a larger EIC Accelerator

The EIC STEP Scale Up Defence call is now open.

That is important news for European defence innovation.

But it also creates a risk.

Some applicants will look at the size of the ticket, see up to €30M in direct equity financing, and assume that the call is simply a larger version of the EIC Accelerator.

It is not.

The EIC STEP Scale Up Defence call is a different instrument, built for a different maturity level, a different financing situation and a different strategic objective. It is not designed for every dual-use startup, and it is not the natural next destination for every company that considers the EIC Accelerator too small.

The deadline is 28 October 2026.

The opportunity is significant.

But the key question is not:

The better question is:

That distinction matters because choosing the wrong instrument can weaken an otherwise strong company. A project that fits the EIC Accelerator may look immature for STEP Scale Up Defence. A company that is genuinely ready for a major defence scale-up round may be underpositioned if it presents itself as a grant-funded development project.

The size of the ticket should not drive the strategy.

The maturity of the company should.

What the EIC STEP Scale Up Defence call is really about

The EIC STEP Scale Up Defence call is part of the broader Strategic Technologies for Europe Platform logic, but it has a specific defence focus. According to the EIC, the scheme is intended to scale strategic technologies and catalyse major funding rounds in critical defence technology areas such as air and missile defence, drones, counter-drones and other defence fields.

This is not a conventional grant call.

It is an equity-only investment instrument.

Eligible companies can receive between €10M and €30M through the EIC Fund, with a total 2026 budget of €100M for the Defence call. The EIC also states that the instrument is expected to catalyse larger funding rounds in the range of €50M to €150M or more, leveraging at least 3 to 5 times the EIC investment.

That co-investment logic is central.

The call is not asking whether a company has an interesting defence technology in isolation. It is asking whether the company is credible enough to become part of a large financing round, attract qualified investors and scale industrial capabilities that are relevant to European security and technological sovereignty.

This changes the evaluation conversation.

For an EIC Accelerator applicant, the discussion often centres on breakthrough innovation, market creation, technology risk, grant-funded development, commercialisation and blended finance logic. For STEP Scale Up Defence, the discussion moves much closer to scale-up readiness, investor confidence, industrial capacity, defence relevance and the ability to absorb a large equity investment.

That is a different test.

Why it should not be confused with the EIC Accelerator

The EIC Accelerator remains highly relevant for many dual-use startups, especially those that are still validating their technology, preparing first market entry, refining their regulatory pathway, building early customer traction or combining civilian and defence applications in a balanced business case.

This matters because the EIC has recently opened to defence and dual-use technologies, which we analysed in EIC Accelerator opens to dual-use technologies. That opening is a major policy shift, but it does not mean every dual-use company should immediately pursue the STEP Defence call.

A dual-use startup may have strong civilian markets, a valid defence angle and a breakthrough technology, but still require a grant-backed development phase before it becomes investable at scale.

For example, a company developing secure AI for critical infrastructure may need further validation before entering sensitive defence procurement environments. A robotics startup may have strong industrial use cases but still need pilots to prove reliability under demanding operational conditions. A materials company may need certification, supply-chain qualification and manufacturing validation before it can credibly justify a major equity round.

In these situations, the EIC Accelerator may still be the more appropriate route.

The EIC STEP Scale Up Defence call is for companies that are beyond that point.

It is for companies that can credibly say: we are not only developing the technology, we are now ready to scale industrial capability, raise a major round and contribute to European defence capacity.

That is a much higher maturity signal.

The real eligibility question is strategic fit

Applicants often treat eligibility as a formal exercise.

Can we apply?

Are we an SME or small mid-cap?

Are we established in an eligible country?

Does our technology fall within the scope?

Those questions are necessary, but they are not enough. In a call like STEP Scale Up Defence, the more important question is strategic fit.

A company may be formally eligible and still be a weak candidate because the financing logic is not mature enough. Another company may have excellent technology but lack a credible investor pre-commitment, a clear scale-up plan or the industrial capacity to justify a large EIC Fund investment.

The official call structure reinforces this. Applicants must provide a full business plan, a pitch deck, a financial plan, freedom-to-operate information and a pre-commitment from a single qualified investor representing at least 20% of the total target funding round. The target funding round itself must be in the €50M to €150M or more range and at least 3 to 5 times the requested EIC investment.

This is not administrative detail.

It is the design of the instrument.

The call is built around the idea that the EIC investment should help unlock a large financing round, not replace the investment market entirely. Therefore, the company must show that private investors already see enough value, urgency and scale-up potential to participate seriously.

That is why applicants should not ask only whether their technology is relevant for defence.

They should ask whether the company can present a financeable defence scale-up case.

Defence relevance is not enough

One of the biggest mistakes applicants can make is to assume that defence relevance alone will carry the proposal.

It will not.

A company may work in drones, counter-drone systems, cyber defence, advanced materials, secure communications, AI, quantum, robotics or sensing, and still fail to present a compelling STEP Scale Up Defence case.

The reason is simple: thematic relevance does not prove scale-up readiness.

A strong application needs to show that the technology matters, but also that the company can scale production, expand delivery capacity, manage security-sensitive customers, deal with procurement realities, protect its intellectual property, operate within relevant regulatory and export-control constraints, and use a large equity round effectively.

This is where many proposals become vulnerable.

They describe a critical technology, but not a critical company.

They explain what the product can do, but not how the business will scale.

They mention strategic autonomy, but do not explain which dependency is reduced, which capability gap is addressed or why the company is positioned to become a serious European player.

For STEP Scale Up Defence, the evaluator and investment decision-makers need to understand more than the technology. They need to understand the company as an investment candidate.

That requires evidence, not slogans.

The role of co-investment logic

The pre-commitment requirement is one of the most important signals in the call.

It forces applicants to connect the EIC request to a broader financing round. This is not just about showing that investors like the company. It is about proving that the EIC participation fits into a real capital formation strategy.

A weak application may say that additional investors will be found after EIC approval.

A stronger application explains who the qualified investor is, why the investor is relevant, what part of the round is already committed, how the remaining round will be structured, how the EIC investment will reduce risk for other investors and how the capital will be deployed across industrial scale-up, market expansion, team growth, supply chain, certification, production capacity or defence customer acquisition.

The financial logic must be specific.

If the company requests €20M from the EIC, the total round cannot be presented as a vague future ambition. It must be linked to a round that is at least 3 to 5 times that amount. It must also make sense in relation to the company stage, valuation, capital needs, investor appetite and scale-up milestones.

This is why the application is closer to an investment-grade scale-up case than to a traditional innovation proposal.

The company is not only asking for support.

It is asking the EIC Fund to become part of a major financing event.

That demands a different level of financial discipline.

When the EIC Accelerator may be the better route

The EIC Accelerator should not be dismissed because STEP Scale Up Defence offers larger tickets.

For many dual-use startups, the Accelerator may be the better strategic choice.

This is especially true when the company is still moving from prototype to validated product, when customer traction is early, when the civilian market remains central, when regulatory or certification milestones still need to be completed, or when the company needs grant funding to reduce technology risk before a larger equity round becomes realistic.

The EIC Accelerator is also a better fit when the project is genuinely dual-use but not primarily defence-led. A company may serve civil infrastructure, healthcare, industrial automation, energy, aerospace, transport or cybersecurity markets while having defence relevance as an adjacent or future segment.

That type of company should be careful not to overstate defence positioning just because the STEP Defence call is open.

A proposal that sounds opportunistic will not become stronger.

It may become less credible.

The better strategy is to select the instrument that matches the real business model. If the company needs to validate a breakthrough technology and prepare market entry, the Accelerator may be the right route. If the company is already preparing a large equity round to scale defence industrial capability, STEP Scale Up Defence may be the right route.

The distinction is not prestige.

It is fit.

When STEP Scale Up Defence may be the better route

STEP Scale Up Defence becomes more relevant when the company has already crossed several maturity thresholds.

The technology should not be merely promising. It should be close enough to deployment, adoption or industrial expansion that a large equity round is justified.

The company should be able to explain who will buy, who will invest, what capacity must be scaled, why the timing is urgent and how the EIC investment will create leverage rather than dependency.

This includes companies that are already building defence customer relationships, scaling manufacturing capacity, expanding field deployment, industrialising complex systems, strengthening European supply chains or entering procurement pathways where capital intensity is high.

The strongest candidates will probably not present the call as a development subsidy.

They will present it as a scale-up accelerator in the literal sense: a way to move faster from validated strategic technology to industrial capability at European level.

That is why the call language matters.

It is not only about innovation.

It is about defence industrial capacity.

Why this call fits the wider European innovation debate

The STEP Scale Up Defence call also reflects a broader European concern: Europe does not only need more research, it needs stronger pathways from deep tech innovation to industrial leadership.

We recently discussed this in the context of the Horizon Europe €167B budget and the innovation gap. The issue is not only how much Europe spends. The issue is whether funding instruments can help companies cross the difficult stages where technology, capital, industrial capacity and market adoption must come together.

Defence innovation makes this challenge sharper.

Critical defence technologies are often capital-intensive. They may require sophisticated testing environments, certification, security-sensitive partnerships, manufacturing scale-up, long sales cycles, export-control awareness and complex procurement pathways.

A small grant may be useful at an earlier stage, but it may not be enough once the challenge becomes industrial scale-up.

That is the policy gap STEP Scale Up Defence is trying to address.

It is not a replacement for the EIC Accelerator.

It is a different layer in the funding stack.

A practical fit test for applicants

Before deciding between the EIC Accelerator and the EIC STEP Scale Up Defence call, applicants should answer a few uncomfortable questions.

• Are we still validating the technology, or are we ready to scale industrial capability?
• Is our business case primarily civilian, genuinely dual-use or mainly defence-focused?
• Do we need grant funding to reduce risk, or equity financing to accelerate scale-up?
• Can we justify a €50M to €150M or larger funding round?
• Do we have a qualified investor able to provide the required pre-commitment?
• Can we explain how the EIC investment will leverage 3 to 5 times more capital?
• Do we have credible evidence of market interest, procurement relevance or defence customer demand?
• Is our freedom-to-operate position clear enough for a scale-up investment process?
• Can we show how the company strengthens European defence technological and industrial capacity?

If the answers are not clear, the company may not yet be ready for STEP Scale Up Defence.

That does not mean the company is weak.

It may simply mean that the EIC Accelerator, another Horizon Europe route, national defence innovation funding or private capital preparation should come first.

The wrong conclusion would be to chase the largest ticket because it looks more attractive.

The right conclusion is to match the instrument to the company stage.

The main message for defence and dual-use applicants

The opening of the EIC STEP Scale Up Defence call is a major moment for European innovation policy. It confirms that the EIC is no longer treating defence and dual-use technologies as peripheral to the innovation agenda. It also confirms that Europe is beginning to connect breakthrough innovation, scale-up financing and strategic capability more directly.

But applicants should be careful.

A bigger ticket is not always a better fit.

For a dual-use startup still proving the technology, the EIC Accelerator may offer a stronger path. For a defence-focused company preparing a major equity round and ready to scale industrial capability, STEP Scale Up Defence may be the better instrument.

The difference is not only the amount of money.

It is the logic of the application.

The EIC Accelerator asks whether a breakthrough innovation can be developed, validated and commercialised with strong European impact.

STEP Scale Up Defence asks whether a company can become a serious European defence scale-up and use large equity financing to strengthen strategic industrial capability.

Those are not the same question.

And they should not be answered with the same proposal strategy.

Where Ruthless Evaluator fits, and where it does not

Ruthless Evaluator does not assess STEP Scale Up Defence applications. That distinction is important. STEP Scale Up Defence is an equity-only scale-up investment call, and companies should rely on the official call documents, EIC guidance, legal advice and investment due diligence support when preparing or assessing a STEP Defence application.

Where Ruthless Evaluator can help is earlier or adjacent to this decision. It can support applicants working on EIC Accelerator, Horizon Europe and other compatible proposal formats where the challenge is to make the problem, innovation, market, impact, risks and implementation logic clear enough for evaluators.

That is particularly relevant for dual-use startups that are still deciding whether they are closer to an EIC Accelerator route or to a later scale-up investment pathway. If the company is still validating the technology, explaining the civilian business case, proving the market need or building a credible commercialisation strategy, the proposal logic needs to be tested before the funding route is selected.

Ruthless Evaluator helps applicants, consultants, startups, SMEs, universities, research centres and innovation teams identify weaknesses in supported proposal formats before submission. It should not be presented as a tool for assessing STEP Scale Up Defence applications.

The opportunity is real.

But so is the risk of misalignment.

Do not chase the largest ticket.

Choose the instrument that your company can credibly defend.
