RIA vs IA vs CSA vs EIC: Choosing the Right Horizon Europe Funding Scheme

Not All EU Grants Are the Same

Horizon Europe offers several distinct funding instruments, each designed for a different stage of the research-to-market pipeline. Choosing the wrong one wastes months of preparation. This guide helps you pick the right instrument for your project.

All information is sourced from the official Horizon Europe Programme Guide and the European Innovation Council website.

Research and Innovation Actions (RIA)

Best for: Universities, research centres, and consortia focused on generating new knowledge and exploring novel technologies.

A RIA funds activities aimed at establishing new knowledge or exploring the feasibility of a new or improved technology, product, process, service, or solution. The emphasis is on scientific and technological excellence.

Key Characteristics

• 100% funding rate — all eligible costs are reimbursed
• Consortium required — minimum 3 independent legal entities from 3 different EU Member States or Associated Countries
• Focus on early-stage research (typically TRL 2–5)
• Results are expected to be published and shared (open science is strongly encouraged)

When to Choose RIA

• Your project is primarily about generating new knowledge
• You need to prove that a concept or technology works (proof of concept, lab validation)
• Your consortium is research-heavy (universities, RTOs)
• You want maximum co-funding (100%)

Innovation Actions (IA)

Best for: Industry-led consortia focused on bringing technology closer to market through prototyping, piloting, and demonstration.

An IA covers activities directly aimed at producing plans and arrangements for new, altered, or improved products, processes, or services. This can include prototyping, testing, demonstrating, piloting, and market replication.

Key Characteristics

• 70% funding rate for most participants (non-profit organisations can receive up to 100%)
• Consortium required — same minimum as RIA
• Focus on later-stage innovation (typically TRL 5–8)
• Stronger emphasis on exploitation and market uptake
• Industrial partners are expected to contribute more own funding

When to Choose IA

• Your technology is already validated in the lab and needs real-world testing
• You have industry partners ready to pilot or demonstrate the solution
• Market entry and commercial exploitation are key outcomes
• You have the resources to co-fund 30% of costs

Coordination and Support Actions (CSA)

Best for: Networks, policy initiatives, standardisation bodies, and coordination platforms.

A CSA covers accompanying measures such as standardisation, dissemination, awareness-raising, communication, networking, coordination, or support services. CSAs do not fund research or innovation activities directly.

Key Characteristics

• 100% funding rate
• Consortium requirements vary by call (can sometimes be single-entity)
• No prototyping or experimental development
• Focus on coordination, networking, policy support
• Typically smaller budgets than RIA or IA

When to Choose CSA

• Your goal is to coordinate existing initiatives rather than create new technology
• You want to build networks, roadmaps, or policy frameworks
• You need to support standardisation or regulatory activities
• Your consortium focuses on stakeholder engagement rather than R&D

European Innovation Council (EIC)

The EIC operates under Pillar III (Innovative Europe) and offers three distinct instruments, each targeting a different stage of breakthrough innovation:

EIC Pathfinder

• Focus: Visionary, high-risk/high-gain research at TRL 1–4
• Funding: Up to EUR 4 million per project (or more if justified)
• Consortium: Minimum 3 entities from 3 different countries (for Open calls)
• 2026 budget: EUR 166 million (Open) + EUR 96 million (Challenges)
• Best for: Radical, early-stage research exploring transformative technologies

Source: EIC Pathfinder

EIC Transition

• Focus: Maturing results from Pathfinder or ERC projects toward TRL 5–6
• Funding: Up to EUR 2.5 million per project
• Consortium: Single entities or small consortia (2–5 partners)
• 2026 budget: EUR 100 million
• Best for: Turning lab results into technology validated in application-relevant environments

Source: EIC Transition

EIC Accelerator

• Focus: Scaling breakthrough innovations at TRL 6–8
• Funding: Grant component below EUR 2.5 million + equity investment of EUR 1–10 million (blended finance)
• Applicants: Single SMEs, startups, or small mid-caps (up to 499 employees)
• Application process: 4 steps — short proposal, full proposal, jury interview, grant agreement
• Best for: Startups and SMEs ready to scale a market-creating innovation

Decision Tree: Which Instrument Is Right for You?

Start here: What stage is your technology or idea?

1. "We have a radical new idea but no proof it works" → EIC Pathfinder (TRL 1–4, up to EUR 4M, consortium)

2. "We have lab results and need to validate in a real environment" → RIA (TRL 2–5, up to 100% funding, consortium) or EIC Transition (TRL 3–6, up to EUR 2.5M, small team)

3. "Our technology works in the lab and we need to prototype and pilot" → IA (TRL 5–8, 70% funding, industry-led consortium)

4. "We have a validated product and need to scale to market" → EIC Accelerator (TRL 6–8, grant + equity, single SME/startup)

5. "We don't need to build technology — we need to coordinate, network, or standardise" → CSA (100% funding, flexible consortium)

Common Mistakes

Submitting a RIA When You Should Submit an IA

If your work plan is 80% prototyping and market testing, evaluators will flag that it doesn't fit the RIA instrument. The type of action is specified in each call topic — read it carefully.

Applying for EIC Accelerator as a Consortium

The EIC Accelerator is for single entities only (SMEs, startups, small mid-caps). If you have a multi-partner project, look at Pillar II calls instead.

Ignoring the Funding Rate Difference

An IA at 70% funding means your consortium needs to cover 30% of costs. For a EUR 5M project, that's EUR 1.5M in co-funding. Make sure your industrial partners can commit this before writing the proposal.

Finding the Right Call

Once you know which instrument fits, search for open calls on the EU Funding & Tenders Portal. Filter by programme (Horizon Europe), type of action (RIA, IA, CSA), and your research area.

You can also explore previously funded projects by funding scheme, topic, and consortium composition in our Project Explorer to see what types of projects have been funded under each instrument.
