Horizon Europe is best known for its collaborative research projects — consortia of universities, companies, and research institutes working together on shared scientific challenges. But within the programme, there is a separate funding universe designed for a different kind of organisation: the deep tech startup, the spin-off, the lone inventor with a breakthrough idea that does not fit neatly into a multi-partner project template.
That universe is the European Innovation Council — the EIC.
Launched as a full instrument under Horizon Europe in 2021, the EIC operates with its own logic, its own funding structures, and its own pipeline: from the earliest scientific breakthrough to a company ready to scale internationally. It does this through three sequential instruments — Pathfinder, Transition, and Accelerator — each designed for a specific stage of the journey from laboratory to market.
This article explains what each instrument does, who it is for, and how together they form a coherent funding pathway for Europe’s most ambitious innovators.
The EIC and its place within Horizon Europe
The EIC sits within Pillar III of Horizon Europe — Innovative Europe — alongside the European Institute of Innovation and Technology (EIT) and the European innovation ecosystems component.
Its mission is distinct from Pillar II’s collaborative research. Where Pillar II funds consortia working on defined scientific challenges, the EIC funds individual companies and research teams pursuing technologies with the potential to create entirely new markets — or disrupt existing ones.
The EIC supports companies — principally startups and SMEs — to scale up high-impact innovations with the potential to create new markets or disrupt existing ones, building on scientific discovery, radical thinking, or technological breakthroughs.
Importantly, the EIC operates on a portfolio logic. Rather than funding incremental improvements, it accepts a high rate of failure as the price of backing genuinely transformative technologies. The instruments reflect this: they are designed for high-risk, high-reward bets, not for safe, predictable outcomes.
EIC Pathfinder: funding breakthrough science at its earliest stage
The Pathfinder is where the EIC pipeline begins. It funds research into the scientific foundations of technologies that do not yet exist in any practical form — ideas that are too early for product development but too promising to be left unfunded.
What it funds: The EIC Pathfinder supports advanced research to establish the scientific basis for breakthrough technologies, operating within Technology Readiness Levels 1 to 4. The emphasis is on scientific vision and long-term potential, not on near-term commercial applications.
Two tracks: The Pathfinder operates through two parallel calls. Pathfinder Open funds research in any field without predefined priorities — the only requirement is scientific ambition and potential for breakthrough impact. Pathfinder Challenges fund specific technology goals defined by the EIC — for example, ultra-efficient batteries, neuromorphic computing, or novel biological interfaces.
Who can apply: For Pathfinder Open, a consortium of at least three independent entities from three different EU member states or associated countries is required. Eligible applicants include universities, research organisations, startups, and SMEs. Mid-caps and large companies cannot apply as coordinators. Pathfinder Challenges allow smaller consortia of two partners or even single applicants.
How competitive: The Pathfinder Open is highly competitive — the 2024 call funded 45 projects from 1,110 proposals, yielding a roughly 4% success rate. Overall, success rates have declined from around 6–8% in earlier years to below 5%. (Source: Science|Business)
What happens next: Pathfinder results that show commercial promise are the natural starting point for the next instrument — EIC Transition.
EIC Transition: bridging the valley of death
Between a scientific breakthrough and a marketable product lies what innovation policy calls the “valley of death” — the stage where promising technologies fail not because the science is wrong, but because no funding mechanism exists to take them from laboratory proof to real-world validation. EIC Transition is designed explicitly for this gap.
What it funds: The EIC Transition supports the maturation and validation of novel technologies from the lab to relevant application environments. It targets innovation activities that go beyond the experimental proof of principle in a laboratory, supporting both the maturation and validation of novel technologies and the development of a business case towards future commercialisation.
In TRL terms, Transition projects typically start at TRL 3–4 and aim to reach TRL 5–6 by project end — moving from laboratory proof to validation in conditions that resemble real-world use.
A key requirement: Applications must build on the results from a previous EIC Pathfinder, FET Flagship, or ERC Proof of Concept project. Applicants must demonstrate that they are the IP rights owner or have the rights to commercialise the IP obtained from the previous project. From 2026, eligible results can also originate from Horizon Europe Research and Innovation Actions funded under the Research Infrastructures programme.
Who can apply: Single applicants — SMEs, spin-offs, universities — are eligible to apply alone or in small consortia of 2–5 partners from both academia and industry.
What happens next: Projects funded through EIC Transition are eligible to submit an EIC Accelerator proposal via the Fast Track scheme — a direct route into the final instrument in the pipeline.
EIC Accelerator: scaling deep tech to market
The Accelerator is the EIC’s most visible — and most distinctive — instrument. It is the only EU funding programme that combines a non-dilutive grant with a direct equity investment from the EIC Fund, making it genuinely unique within the European funding landscape.
What it funds: The EIC Accelerator supports companies with innovations that have the potential to create new markets or transform existing ones, built on scientific discovery or technological breakthroughs, with innovation activities currently at TRL 6 or above, requiring significant funding over a long timeframe before returns can be generated.
Who can apply: The Accelerator is exclusively for individual startups and SMEs — not consortia. Larger companies are not eligible. The applicant must be a single legal entity established in an EU member state or associated country.
The application process: The 2026 Work Programme introduces a major simplification and shortening of the EIC Accelerator evaluation process, moving from two full application cut-offs in 2025 to six batching dates in 2026 — January, March, May, July, September, and November — enabling faster investment decisions post-selection.
How competitive: The EIC Accelerator has a success rate of 4–7% end-to-end. It is one of the most competitive funding instruments in Europe, and the quality of the application — particularly the business case and the team — is as important as the technology itself.
How the three instruments work together
The Pathfinder, Transition, and Accelerator are not independent programmes. They are designed as a pipeline — each one preparing its most successful projects for the next stage.
A research team that receives Pathfinder funding to validate a scientific breakthrough can apply for Transition funding to mature that technology towards a specific application. If that work produces a validated prototype with clear commercial potential, the company can apply for Accelerator funding — and, through the Fast Track scheme, do so directly without going through the standard Step 1 process.
This pipeline logic is intentional. The EIC is trying to build European deep tech companies from the ground up, not just fund individual projects. The Business Acceleration Services available to all EIC-funded entities — coaching, investor access, corporate partnering, market intelligence — reinforce this: the goal is not just to fund good science, but to turn good science into companies that scale.
How the EIC differs from collaborative Horizon Europe projects
For organisations familiar with Horizon Europe’s standard collaborative projects — RIA, IA, CSA — the EIC operates according to a different logic in several important ways:
- Single entities, not consortia. The Accelerator funds individual companies. The Pathfinder requires a consortium, but a small one. The collaborative structure of Pillar II — 10 to 20 partners coordinated over years — does not apply here.
- Equity as well as grants. The Accelerator combines grant funding with direct equity investment. No standard Horizon Europe instrument does this.
- Commercial ambition is mandatory. EIC proposals are evaluated not just on scientific quality but on the credibility of the path to market. A technically excellent proposal with no credible commercial case will not be funded.
- Higher risk tolerance. The EIC explicitly accepts that many of its funded projects will not succeed commercially. The portfolio is designed to absorb failure in exchange for the possibility of backing the next category-defining technology.
Final thoughts
The EIC represents a genuinely different approach to EU innovation funding — one designed for the organisations that are building something entirely new, not advancing an established field. For startups and deep tech SMEs with technologies at any stage from laboratory to pre-commercial, understanding the Pathfinder, Transition, and Accelerator — and which one fits where they are today — is the starting point for engaging with this part of the Horizon Europe ecosystem.
In a separate article, we cover the EIC Accelerator in detail: the application process, what evaluators look for, and the most common reasons strong applications are rejected.
One thing worth noting for organisations that do secure EIC funding: winning the grant is the beginning, not the end. EIC projects — particularly Pathfinder and Transition — involve Grant Agreements, deliverables, reporting periods, and financial justification requirements that are structurally similar to standard Horizon Europe projects. The operational and financial management challenge is real, and it arrives from day one. Kronis is built to support exactly that — giving funded teams the infrastructure to manage execution and stay audit-ready, so they can focus on the science and the market, not the administration.
