Why strong EIC projects still get a NO GO

A practical guide to building an EIC Accelerator Full Proposal that is clear, credible, and evaluator ready.

Many companies approach the EIC Accelerator with strong technology, a credible market opportunity, and even clear strategic relevance for Europe. And yet, many still fail at Full Stage.

In many cases, the issue is not the innovation itself. The issue is the way the Implementation Plan and the Lump Sum budget are built, explained, and connected.

This is one of the most underestimated parts of the EIC Accelerator process.

A company can have an excellent technology and still lose the case if its work packages, tasks, milestones, deliverables, timings, risks, and budget logic are not clear enough for evaluators. At Full Stage, these elements are not secondary. They are part of how execution credibility is judged, and the official full stage criteria explicitly assess the implementation plan, the realism of milestones and deliverables, and whether estimated lump sum costs are reasonable and non excessive.

That is exactly where many teams struggle.

For founders and management teams who are not deeply familiar with European funding logic, it is not easy to understand how to structure an Implementation Plan that reads clearly to evaluators, or how to build a Lump Sum budget that feels coherent, justified, and aligned with the actual work plan. The official structure requires detailed work packages, tasks, milestones, deliverables, risks, subcontracting logic, and purchase cost explanations, which makes this section much more demanding than it often appears at first sight.

Public information helps, but it rarely explains in practical terms how evaluators actually react to weak or strong execution logic. That is why many technically solid companies still underperform: not because the technology is weak, but because the implementation story is vague, the milestones do not prove real progress, the work packages are not specific enough, or the budget does not convincingly follow the work. The EIC 2026 framework itself reinforces this focus on implementation quality and a more streamlined but still demanding evaluation logic.

That is why we developed this guide.

It brings together Silicon Capital Partners’ experience across dozens of EIC projects, combined with the official EIC logic, the formal implementation and lump sum requirements, and the recurring patterns we see in real evaluation reports. The goal is simple: to help companies understand what evaluators really expect when they read the Implementation Plan and the Lump Sum budget at Full Stage.

This guide is designed to help companies build these two parts in a way that is clearer, stronger, and more evaluator ready. It focuses on the practical do’s and don’ts that most often shape evaluator confidence: how to define work packages properly, how to describe tasks with enough specificity, how to set meaningful milestones, how to make risks and mitigation credible, and how to ensure that the lump sum budget supports the implementation logic instead of weakening it. The full stage evaluation criteria make that connection explicit.

At Silicon Capital Partners, our view is straightforward: if a company is seriously considering the EIC Accelerator, it should not treat the Implementation Plan and the budget as annexes to complete at the end. They are two of the main places where evaluators decide whether the case feels executable or not.
