Our Approach
More than writing — a full strategic advisory service
EU grant proposal writing is not a copywriting task. Competitive proposals require deep programme knowledge, alignment with evaluator criteria, rigorous budget construction, and credible consortium assembly. A well-written narrative on an ill-aligned concept will not succeed.
Zeus Consulting brings 30+ years of EU funding expertise. We work with universities, municipalities, SMEs, NGOs, and research centres across Europe — managing the full proposal lifecycle from the first eligibility call to portal submission.
- Proposal writing for all EU programmes (Horizon Europe, Erasmus+, INTERREG, ESF+, Digital Europe, LIFE)
- Consortium partner identification and brokerage
- Budget construction and financial compliance
- Independent quality review before submission
- Post-award project management and reporting

Misalignment with call objectives
→ We build proposals backwards from the call text
Common failure
Vague impact narrative
→ Quantified outcomes, specific target groups, credible exploitation plans
Common failure
Weak consortium
→ Strategic partner matching from our 200+ organisation network
Common failure
Budget inconsistencies
→ Line-by-line justification built for audit resilience
Common failure
Last-minute preparation
→ We engage 4–8 months before deadline for optimal results

Common Questions
Grant Writing — Frequently Asked Questions
What does an EU grant writer do?
An EU grant writer develops the technical and strategic content of a European Commission funding application: call analysis, positioning against evaluation criteria, Part A and Part B, work plan, deliverables, milestones, and budget. For Horizon Europe, the writer also coordinates consortium input, review cycles, and portal submission. Zeus Consulting's Athens-based team has worked across major EU programmes since 1992.
How long does it take to write a Horizon Europe proposal?
A competitive Horizon Europe RIA or IA typically requires 4–6 months from concept to portal submission, including positioning, consortium building, writing, budgeting, review, and submission. Erasmus+ and LIFE proposals usually take 2–4 months. Engage us as early as possible, ideally when you identify a suitable call.
What is the success rate for EU funding proposals?
Rates vary by programme and action type. The EU-wide average for Horizon Europe competitive calls is approximately 12–14%. Our proposals consistently outperform this average through alignment with evaluator criteria, strategic consortia, and rigorous review across 100+ delivered projects. Our free AI Proposal Evaluator and Eligibility Assessment provide a useful first assessment.
Do you write EU proposals for organisations outside Greece?
Yes. From Athens, we work with universities, research centres, SMEs, municipalities, and NGOs across EU Member States and associated countries. Most EU programmes require consortia spanning at least three countries. We have supported lead applicants from Greece, Cyprus, Italy, Germany, Spain, and beyond.
