Key takeaways

A vague vision is the most common rejection driver – describe the problem, market size, and why your team is the right one.
Reviewers want evidence: surveys, interviews, and Letters of Intent prove real market interest.
Every expense in the financial plan must map to a milestone.

1. Unclear founding vision

If your vision sounds vague, reviewers can't tell which concrete problem you want to solve. A diffuse outlook on 'digital revolution' or 'sustainable future' is not enough to show market relevance. In a few clear sentences describe which pain point you're addressing, how large the market is, and why your specific team can deliver the solution.

Booking confirmation stamp
Customers can 'book' you even before launch – the simplest way to show market demand.
Describe precisely: which problem you solve, for whom, and why right now.
Provide hard numbers: how many people are affected, and how severe is the pain?
Show why your team is uniquely positioned to solve this.

2. Missing validation data

EXIST doesn't fund castles in the air – it funds data-driven concepts. Validation means proving that real people or companies are willing to pay for your solution. Early surveys, structured interviews, and non-binding letters of intent are invaluable. B2B models are validated through company conversations on LinkedIn; B2C through surveys. Link validation to your business model: does the problem occur once (one-time payment) or repeatedly (subscription)?

Full calendar of user interview bookings
This is what your calendar should ideally look like when booking user interviews.
Conduct surveys or interviews and document concrete results.
Ask B2B and B2C contacts: how much are they willing to pay?
Collect at least 3 Letters of Intent (better 5) for B2B projects.

3. Incomplete financial plan

A patchy plan looks unprofessional. Help reviewers assess it with clear financial diagrams and key metrics. More importantly, link every expense to a milestone: what do you want to achieve and which resources – team, materials, coaching – do you need for it? Detail the first 12 months, then a rough 5-year forecast. The further into the future, the more uncertainty – don't over-engineer the outer years.

Financial KPI chart example
EBIT, CAC and more. Axes must be labelled; lines must be distinguishable in black-and-white. Mark key points like Break-Even.
Create a detailed cost and revenue plan for the first 12 months.
Build in a 5-year forecast that maps team growth and scaling.
Use industry benchmarks (e.g. typical SaaS growth rates) as reference points.

4. Weak team profile

Reviewers place great value on a competent and complementary founding team. How you met shows whether you can work together through the EXIST phase and beyond. Use the space: two years as flatmates, friends since kindergarten, four years studying together, same sports club. Did you build a podcast together? How did the idea come about? Does it drive you emotionally as well as commercially? Include all of that – and don't be too modest.

Founding team photo
A professional team photo next to your bios lets reviewers connect with you immediately.
Highlight your previous successes and team dynamics.
Describe how you complement each other and why you work well together.
Use LinkedIn, GitHub, and CVs: a coherent profile is persuasive.

5. Weak university connection and unclear innovation

The university connection is your USP in the EXIST application. Show that your idea is grounded in academic research and that you benefit from your university's infrastructure. Describe which labs, equipment, or test facilities you use – but don't imply the IP belongs to the university. Name your EXIST mentor, their field, and how they support you. Reference papers, studies, or theses that underpin your concept. Google Scholar, Arxiv, Elsevier, and PubMed are your starting point.

Researcher preparing for an expedition
Founding is an adventure – but like every successful adventure, it must be well planned. Treat the EXIST application as preparation to go into execution with a plan.
Show your integration into research and teaching: labs, professors, infrastructure.
Attach cooperation agreements or supervision commitments.
Cite scientifically and consistently – every innovation claim needs a reference.
