EIC Accelerator: grant plus equity for deep tech.

The EIC Accelerator is the European Innovation Council's flagship instrument for high-risk, high-impact deep-tech start-ups and SMEs. It combines a non-dilutive grant of up to EUR 2.5 million with an equity investment of up to EUR 10 million to take breakthrough innovations from prototype to scale-up.

1. What is the EIC Accelerator?

The role of the instrument and the kind of company it targets.

The EIC Accelerator is the most ambitious pillar of the European Innovation Council. It is built to bridge the gap between cutting-edge research and the commercialisation of breakthrough technologies, funding innovations that are too risky for private investors alone but have the potential to create new markets or disrupt existing ones. It focuses on deep-tech innovation with high technological and financial risk, and supports companies along the journey with funding, business acceleration services, and direct equity. One feature to note: in an EIC Accelerator proposal, financial and investment maturity matter as much as technological maturity.

2. Funding modalities

The three ways the money can be structured.

The Accelerator offers three modalities:

Blended finance: the most common option, combining a grant for technological development (TRL 6 to 8) with an equity investment for commercial scale-up (TRL 9).
Grant-only: up to EUR 2.5 million for companies that do not want to give up equity.
Equity-only: EUR 1 million to EUR 10 million in direct investment from the EIC Fund for companies that no longer need grant support but need capital to scale.

The programme runs an Open call, for any technology or sector, alongside Challenge calls that target specific EU strategic priorities such as advanced materials, energy storage, and other areas of technological sovereignty.

3. Who can apply

The eligibility, including the special rules for mid-caps and non-EU entities.

Eligible applicants are single start-ups and SMEs established in an EU member state or a Horizon Europe associated country, as well as individuals intending to create such a company. Small mid-caps (up to 499 employees) can participate in specific cases, particularly for equity-only support. UK entities are eligible for grant-only funding, and Switzerland participates again through Horizon Europe. A company can have only one active application at a time, and applicants from third countries must relocate before the full-proposal stage.

4. How much you get

The size of the grant and equity, and the 70 percent rate on the grant.

The grant covers 70 percent of the eligible innovation costs, so the company self-finances the remaining 30 percent, up to a grant of EUR 2.5 million for TRL 6 to 8 activities over up to 24 months. The equity component runs from EUR 1 million to EUR 10 million, provided by the EIC Fund as a minority investor with a stake of up to around 25 percent, and even larger investments are possible through the EIC scale-up route. Blended finance therefore packages a substantial grant and a sizeable equity ticket into one instrument.

5. The three-step process and deadlines

How the staged evaluation works and the 2026 dates.

The process has three steps. Step 1 is a short proposal (a short form, a 10-slide pitch deck, and a 3-minute video) that can be submitted year-round and is evaluated within about four to six weeks; applicants with at least three positive scores proceed. Step 2 is a full proposal (around 20 pages plus an implementation plan, financials, pitch deck, video, freedom-to-operate analysis, and letters of intent), with six cut-offs in 2026: 7 January, 4 March, 6 May, 8 July, 2 September, and 4 November. Step 3 is a jury interview for the top-ranked proposals. The full journey typically takes 6 to 12 months.

6. Notes

Realistic expectations and how it fits the wider toolkit.

The EIC Accelerator is one of the largest single-company funding instruments in the world, but also one of the most competitive, so it suits genuinely breakthrough, investment-ready companies rather than incremental projects. It is distinct from the EIC Pathfinder, which funds earlier-stage research. For companies whose project is strong but not at this level, national instruments such as the Forschungszulage, ZIM, or KMU-innovativ are more accessible, and the grant part of any EIC funding remains subject to the rule that the same costs cannot be double-funded.

7. Funding modes and calls

The EIC Accelerator is one instrument with three funding modes and two call types.

There are three modes. Grant-only is a lump sum below €2.5M for innovation activities at TRL 6–8, at a 70% rate, and can be used only once per company during Horizon Europe. Blended finance, the standard model, combines that grant with an equity investment of €1–10M for the scale-up. Equity-only provides €1–10M of direct equity or quasi-equity from the EIC Fund, for a company ready to scale at TRL 9 without a grant. The EIC Fund invests as a minority investor (commonly up to ~25%) to crowd in private capital; investments above €10M (up to €30M) run through the separate EIC STEP Scale Up call, which cannot be applied for at the same time.

There are two call types. The Open call has no thematic restrictions (2026 budget €414M); the Challenges call targets pre-defined strategic topics such as advanced materials for energy and storage, biotech for sustainable agriculture, fusion concepts, climate-adaptation deep-tech and critical raw materials (2026 budget €220M). Fast Track and Plug-in routes let proposals from certain Horizon projects or certified national programmes go straight to the full proposal. Every funded company also gains the EIC's Business Acceleration Services: coaching, mentoring and connections to investors and corporates.

8. Eligible and ineligible costs

The grant and the equity work differently, and the eligible scope is unusually broad.

The grant covers 70% of eligible costs as a lump sum across the Horizon Europe categories, personnel, equipment, travel, materials and subcontracting, plus a 25% flat rate for indirect costs. Because the focus is market preparation, many activities other instruments exclude are eligible here: building and testing demonstrators with customers, running clinical trials or obtaining regulatory approvals, up-scaling and miniaturisation, and building the commercialisation and financing strategy. The equity finances scale-up and market deployment as a direct investment from the EIC Fund, not as reimbursed costs.

Out of scope are early-stage or low-maturity work (below ~TRL 5/6, which belongs to EIC Pathfinder or Transition), incremental non-breakthrough projects, and a second grant-only (it can be received only once). Companies that cannot access the EIC Fund (notably UK and some associated countries) are limited to grant-only. A company may have only one live application, cannot apply to the Accelerator and EIC STEP Scale Up at once, and after three unsuccessful submissions cannot reapply under Horizon Europe. The remaining 30% of innovation cost must be co-financed.

9. How it's evaluated

Three investment-grade criteria, applied by experts at the proposal stages and an investor jury at interview.

Proposals are judged on Excellence (the breakthrough nature, novelty, TRL and IP position), Impact (market-creation potential, business model, scalability and the commercialisation and financing strategy) and Level of Risk and Implementation (the team, work plan, milestones, and the justification for EU support). Selection runs in steps: at Step 1 four experts assess remotely and a GO is required; at Step 2 the top-ranked proposals, about 2.5× the available budget, are invited to interview; at Step 3 an EIC Jury of investors and entrepreneurs decides. Because the jury is investor-led, financial maturity and investment-readiness weigh as heavily as the technology. A Seal of Excellence (for full proposals scoring at least 13/15) is a quality mark, not a funding entitlement, and the interview is frequently decisive.

10. Industry examples

The Open call is field-agnostic; the Challenges target strategic priorities. These are illustrative project shapes, not named beneficiaries.

Hardware-intensive deep-tech, a novel device, robotics or photonics/quantum component ready to scale from validated prototype to market.
Industrial and medical biotech, a breakthrough therapeutic, diagnostic or bio-process moving through trials and approvals.
Energy-transition technologies, advanced materials for renewables and storage, or fusion-related concepts.
Climate-adaptation deep-tech and critical raw materials solutions strengthening EU resilience.
Advanced digital technologies, AI, advanced computing or cyber solutions with breakthrough potential and a clear scale-up path.

The common thread is the Accelerator logic: a single company with a mature, breakthrough, market-creating innovation, ready to scale with blended finance, and able to show a need for EU support. Early-stage, incremental, or readily privately-fundable projects point to EIC Pathfinder/Transition, a national programme, or a private raise.

11. Common mistakes

The errors that most often sink an EIC Accelerator application.

Applying too early, below ~TRL 5/6, where the project belongs to EIC Pathfinder or Transition.
Pitching an incremental innovation, when the bar is breakthrough and market-creating.
A weak business or financing case, financial maturity matters as much as the technology.
No clear need for EU support, the additionality argument that private capital alone would not fund this step at this risk.
Treating the equity as a grant, blended finance is dilutive, the EIC Fund takes a minority stake.
Ignoring fund-access limits, UK and some associated countries can only receive grant-only.
Forgetting grant-only is once per company during Horizon Europe.
