How to find the right VC firm in Budapest
Not every investor will be the right fit — and in a growing ecosystem like Budapest, choosing the wrong one can slow your momentum. Whether you're raising pre-seed or Series A, targeting VCs in Budapest that align with your vision is key.
To raise effectively from VCs in Budapest, founders should evaluate:
- Sector specialization: Is the fund active in your space (e.g., SaaS, fintech, climate)?
- Stage focus: Pre-seed vs. growth? Make sure your traction matches their thesis.
- Portfolio synergy: Look at who they've already backed — are you a strategic fit?
- Speed and support: Some investors move fast and stay hands-on, others are more passive.
- Geographic interest: Many firms look for potential to expand beyond Hungary or into the EU.
