In the EIC Accelerator, Full Stage Is Not a Longer Proposal. It Is a Different Burden of Proof.
A Short Proposal can succeed because the opportunity is credible enough to deserve deeper evaluation. At Full Stage, that is no longer enough.
The question changes from:
“Could this be a strong EIC case?”
to:
“Can the company actually prove the case it is making?”
Many founders approach the Full Proposal as an expanded Short Proposal: more pages, more detail, more explanation. That is the wrong mindset.
The Full Proposal should be treated much more like a due diligence file. A statement that was plausible at Short Stage now needs to become traceable.
- TRL claims need clear evidence of what was tested, where and under which conditions.
- Market claims need to connect to a realistic segment, customers, pricing and achievable market capture.
- Differentiation claims need to survive comparison with named competitors and alternatives.
- Growth projections need commercial mechanics behind them.
This also applies to IP, regulation, team, risks and funding need.
But the Full Proposal should not only contain claims. It should contain ways for the evaluator to verify them.
1. Use letters as evidence, not decoration.
Letters of intent, support and recommendation can validate the problem, the disruptive nature of the innovation, customer interest, technical validation or growth potential. A generic “we support this company” adds little. A letter confirming a specific claim is much stronger.
2. Use sources that genuinely validate what you write.
Market figures, regulatory pressure, competitor information and industry claims should be backed by reliable sources. This matters especially when AI is used.
AI can accelerate research and drafting, but it is not the source of truth. The underlying evidence still needs to exist and support the claim.
3. Turn existing expert documents into evidence.
Many companies already have market studies, competitor analyses, technical reports, regulatory assessments, FTO reports or relevant media coverage.
If those documents support an important claim, reference them and make them accessible where appropriate. The objective is not to make the evaluator read another 80 pages. It is to show that the statement is backed by deeper evidence.
A Short Stage GO should not be interpreted as confirmation that the case has already been validated. It means the case was strong enough to continue.
Full Stage is where the assumptions start being audited.
Before adding more text, ask:
→ What evidence proves this?
→ Is that evidence credible and accessible?
→ Does it actually validate the claim?
More detail does not automatically create more credibility. Traceable evidence does.
