EIC Accelerator

Up to €15m in blended finance for deep-tech SMEs from TRL 5, with a 5–8% success rate.

The EIC Accelerator is the EU's most important single-company funding instrument for innovative SMEs and start-ups. It combines a non-repayable grant of up to €2.5m with an equity investment from the EIC Fund of up to €10m, giving a maximum of €15m per company. It requires a demonstrable breakthrough or deep-tech innovation from TRL 5. The three-stage procedure (short application, full application, jury pitch) follows a VC process, not a classic research application.

Eligibility

Legal form: a for-profit company (GmbH, AG, UG, SE, Ltd, SAS and so on). Research institutions, NGOs and natural persons cannot apply directly
SME status (up to 250 employees, up to €50m annual turnover or a balance sheet total up to €43m) or small mid-cap status (up to 500 employees); linked and partner companies are included
The company is based in an EU member state or a country associated to Horizon Europe (including Norway, Iceland, Switzerland, Israel, Ukraine, Türkiye and the UK; UK companies are excluded from the equity component)
The single beneficiary principle: exactly one company applies. No consortium, no mandatory partner
A breakthrough or deep-tech innovation with European or global scaling potential; incremental improvements are rejected
Technology readiness level (TRL) of at least 5 at the time of application (component validation in the relevant environment demonstrably complete)
Civil applications only; military and purely defence projects are excluded, and dual use is assessed case by case
A full application requires a prior GO result on the short proposal (WP2025 or WP2026)
Fewer than 3 previous rejections in the EIC Accelerator under Horizon Europe
Registration with a participant identification code (PIC) in the EU Funding & Tenders Portal
A gender equality plan (GEP) is required for organisations with 50 or more employees
The EU validation service's financial viability check has to be passed (a balance sheet analysis)

Eligible costs

Staff costs for employees working directly on the project (salaries including ancillary wage costs; evidenced by timesheets or the declarative method under the MGA)
Subcontracting to external providers (core tasks such as your own R&D may not be outsourced; justify and list them in the application in advance; not part of the base for overheads)
Travel and subsistence
Equipment (pro rata depreciation, limited to the period of use on the project)
Consumables and other goods
External services such as certification, testing, studies and expert opinions
IP protection costs (patent and trade mark filings, where project-related and specified in the application)
Indirect costs (overheads): a 25% flat rate on all eligible direct costs excluding subcontracting, with no itemised evidence required
Scaling and market entry costs (building sales, international expansion, production scale-up), financed through the EIC Fund's equity component rather than the grant

Common pitfalls

Incremental innovation instead of a breakthrough

The EIC Accelerator finances only market-changing deep-tech innovation. Anyone describing their product as 'faster, cheaper or better' without evidencing a genuine technological leap gets a NO GO, however strong the company is.

Overstating the TRL

From 2026 a technical due diligence interview with an independent expert already takes place at the full application (stage 2). Anyone claiming TRL 7 with only a laboratory demonstration falls out here. Better to document TRL 5 solidly than TRL 7 on thin evidence.

Underestimating the resubmission limit

After exactly 3 rejections in the EIC Accelerator under Horizon Europe, resubmission is permanently ruled out. Rejections at every stage count. After the second rejection at stage 1 there is a 12-month bar. The limit runs to the end of 2027.

Underestimating equity due diligence

The EIC Fund carries out its own investment due diligence, which can take 6 to 12 months. Bridge financing for that period has to be planned; anyone unprepared runs into liquidity problems even though the application succeeded.

The CEO absent from the interview

At the jury interview (stage 3) the CEO has to attend in person. A stand-in founder or a presentation without the CEO regularly leads to a NO GO; alongside the technology, the jury expressly assesses the entrepreneurial team.

Market analysis not validated bottom-up

A total addressable market of '€1bn' with no sources and no concrete customer pipeline doesn't convince the jury. What is required are evidenced market sizes (Gartner, Grand View, industry associations) combined with genuine letters of intent from customers willing to pay.

The application process

1 — Preparation and PIC registration. Register your company with a participant identification code (PIC) in the EU Funding & Tenders Portal (ec.europa.eu/info/funding-tenders). Legal entity validation by the central validation service takes several weeks, so start that step early. In parallel: check SME status (including linked companies), document the TRL, choose the funding option (grant only, blended finance or equity only) and decide the track (Accelerator Open or Challenges).
2 — Short application (stage 1, rolling). The short application can be submitted at any time (rolling submission). It comprises a structured online form, a pitch deck (max. 10 slides, PDF, VC standard) and a pitch video (max. 3 minutes, MP4). Four independent remote experts assess it; the result (GO or NO GO) comes within 4 to 6 weeks. On a GO you receive an invitation to submit a full application.
3 — Full application (stage 2, cut-off based). The full application consists of part A (administrative forms in the portal) and part B (the main document, NEW for 2026: max. 20 pages, previously around 50) plus structured annexes (an IP strategy with a freedom-to-operate analysis, a work plan, a budget, a 5-year financial projection, team CVs, letters of intent). NEW from 2026: a technical due diligence interview with an independent expert already takes place at this stage. Submit by 17:00 Brussels time on one of the six cut-off dates in 2026 (7 Jan, 4 Mar, 6 May, 8 Jul, 2 Sep, 4 Nov). The scoring result comes after 8 to 12 weeks.
4 — Jury interview (pitch, stage 3, three times a year). If invited: a 10-minute pitch plus 35 minutes of Q&A before a jury panel of investors, entrepreneurs and innovation experts (45 minutes in total). The CEO has to attend; the CTO is recommended. Invitations are limited to a maximum of 2.5 times the available budget. The final result (GO or NO GO) comes around 3 weeks after the interview week.
5 — Grant agreement preparation (GAP). After a GO, grant agreement preparation starts and takes around 2 to 3 months. The description of action (work plan, budget, reporting periods) is finalised and the grant agreement is signed electronically through the EU portal. For blended finance, the EIC Fund's own investment due diligence runs in parallel (6 to 12 months, term sheet and shareholder agreement).
6 — Delivery and reporting. Once the grant agreement is signed you receive pre-financing of typically 40 to 60% of the grant. Further payments follow approval of the periodic reports (typically every 12 to 18 months). Where cumulative grant funding reaches €430,000 or more, a certificate on financial statements from an independent auditor is required. Monthly timesheets (or the declarative method) are mandatory.

How upsmart helps

We check whether your project meets the TRL and target group criteria of Accelerator Open or one of the five Challenges themes, and whether national co-financing (ZIM or KMU-innovativ, say) can be cumulated without covering cost items twice. We write the draft application ready for assessment; your team decides. We keep an eye on the cut-off deadlines and the resubmission limits (no more than three rejections, a twelve-month bar).

Combining it with other programmes

Complementary financing of different cost items through national programmes (ZIM, KMU-innovativ, EXIST, state ERDF programmes) is permitted provided no identical cost items are financed twice. Within the same project, a cost item may only be funded by exactly one programme. Combining it with EIC Pathfinder (basic research, TRL 1–4) or EIC Transition (TRL 3–5) for upstream phases makes strategic sense but isn't possible simultaneously for the same innovation.

Frequently asked questions

Yes. Experience with EU funding isn't a requirement; first-time applicants are expressly welcome. What matters are the TRL (at least 5), the breakthrough character of the innovation and the quality of the founding team. Involving the national contact point (NKS EIC) and the BMFTR's EU office early is advisable.

Accelerator Open is technology-open and has a 2026 budget of €414m. The Accelerator Challenges focus on five strategic themes (advanced materials for renewable energy, fusion technologies, agricultural biotechnology, critical raw materials, climate adaptation deep tech) with €220m. In the Challenges track the project has to fit one of the five themes exactly; in return the competition is more narrowly defined thematically.

Grant only is a fully valid option. You then receive up to €2.5m in grant (70% of eligible costs) with no dilution of your shares. You have to set out plausibly in the application that you can cover the remaining capital need to market readiness elsewhere. UK companies can in any case only use grant-only mode.

Realistically 12 to 18 months: short application result 4 to 6 weeks, full application scoring 8 to 12 weeks, jury interview result around 3 weeks, grant agreement preparation 2 to 3 months. With blended finance the EIC Fund's due diligence adds 6 to 12 further months. Bridge financing is therefore indispensable.

Every rejection at every stage (short, full, interview) counts. After the second rejection at stage 1 there is a 12-month bar; after the second rejection at stage 2, likewise 12 months plus a return to stage 1. After three rejections in total, resubmission under Horizon Europe is permanently ruled out. Successful short proposals don't count as rejections.
