A seed fund backs the founding team and an early signal. Revenue is nice but it is not always required yet.
They want a large market and a sharp wedge into it. A clear story will beat a long list of product features.
Most seed funds here will lead or co-lead the round. One strong lead makes the rest of the raise easier.
Also see our full Budapest SaaS investors list here. Ellty shows exactly which seed fund opened your deck.
As the CEE venture ecosystem reaches a new level of maturity, established local funds have become key partners and important signals for global investors.

What seed money should buy
Seed money should buy 18 to 24 months of real runway. Spend it to find product-market fit and nothing else.
Most seed rounds here land between EUR 300K and 2M. That buys a small team and your first go-to-market.
Investors want a clear plan for the next 18 months. Vague spending plans tend to kill seed rounds fast.
Keep your backers posted with simple investor updates. Ellty keeps every seed fund on a single tracked link.
State capital fills the gap
Hiventures is state-backed and very active at seed. It writes early cheques few private funds will match.
The EIF and EBRD both sit behind many of these funds. EU money quietly powers the whole local seed market.
State money is patient, but the process can be slow. Plan for longer timelines than with a private round.
Tighten your full pitch deck before any state pitch. Ellty tracks who on the panel actually reads it all.
