EIC Pathfinder Open 2026 raises the ambition of Europe’s frontier science

The European Innovation Council (EIC) has recently opened the Pathfinder Open 2026 call, aimed at funding frontier science at a very early stage of scientific development. The call has a budget of €166 million and will remain open until 12th May 2026.

Pathfinder Open represents one of the main funding opportunities for projects that have already identified basic scientific principles observable in the laboratory and aim to turn them into components validated in a controlled environment. Projects can receive up to €4 million in funding, extendable in duly justified cases, which is a significant increase compared with previous calls.

Funding is awarded entirely as non-repayable grants, for both companies and public entities, and is delivered largely in lump-sum form, which markedly simplifies administrative management during project implementation. In addition to financial support, the EIC offers mentoring services, coaching and access to acceleration programmes that facilitate the transition to later development stages, as well as connections with other EIC instruments, such as EIC Transition or the EIC Accelerator.

Nevertheless, competition in Pathfinder Open is very high. “In previous calls, only a small percentage of the proposals submitted have secured funding,” notes David Rebollo, a consultant in the Entrepreneurship knowledge area at Zabala Innovation. In his words, to succeed in this programme, “proposals have to be especially robust, well structured and aligned with the evaluator’s expectations”. “Having a high-level consortium – combining scientific excellence, technological capability and a clear vision of impact – is now more critical than ever,” stresses Francesc Fabrega, a consultant in the same area.

What is changing in 2026

These experts point to one of the main novelties of this edition of Pathfinder Open: the expected scale of projects. Whereas in the 2025 Work Programme the usual budget was around €3 million, in 2026 the EIC considers €4 million to be an appropriate scale. “The change is not merely quantitative,” Rebollo highlights, “but reflects a clear expectation of proposals that go deeper, are better articulated and have an explicit decision-making logic”.

In this way, the focus is no longer on isolated demonstrations, but on generating a solid body of evidence that combines validation of the scientific mechanism with reproducibility and the robustness of results. “Elements such as the intellectual property protection strategy, critical dependencies in materials or equipment, or key technological risks must be integrated from early stages, without undermining the exploratory nature of the project,” Fabrega indicates.

This change of scale has a direct impact on evaluation. “Evaluators are increasingly less tolerant of plans based on generic or overly open milestones, and they expect milestones geared towards demonstrating concrete results and enabling clear technical decisions,” Rebollo warns.

In parallel, lump-sum funding is becoming established, which reinforces the need for coherence between objectives, the work plan and the budget. According to these experts, work packages must be defined as outcome units, with verifiable deliverables, well-formulated decision milestones and credible risk management.

Lastly, under the EIC Pathfinder Challenges 2026 call (with a budget of €166 million and a deadline of 28th October), the portfolio approach is reinforced. Proposals are assessed not only for their individual quality, but also for their specific contribution to the challenge objectives and their complementarity with other funded projects. In this context, according to Fabrega, “it is key to explain clearly which technological gap is being filled and how the project’s results can connect with other initiatives within the Challenge”.

Recommendations for writing a Pathfinder project in 2026

“What vision underpins the project? What scientific leap is being proposed and why do you want to make it? Answering these questions credibly is essential for a Pathfinder proposal to be competitive in 2026,” in Rebollo’s words. In this regard, the concept of “critical uncertainty” is paramount and the project has to resolve it. “It is the uncertainty that, if not resolved, would invalidate the whole idea,” Fabrega explains.

From there, this expert adds, “the work plan will need to be structured around truly decisive experiments, defined through clear, measurable success criteria oriented towards decision-making”. As for the end of the project, it “should not be framed as a future promise, but as a set of solid evidence, embodied in a well-scoped proof of principle that demonstrates what is scientifically validated,” he adds.

And, in Pathfinder Challenge, “you have to write ‘for the challenge’, explaining with crystal clarity which technological need the project addresses, what differences exist compared with other approaches, and what specific contribution the proposal makes to the programme’s overall portfolio,” Rebollo concludes.
