ZAKA

ZAKA was founded in Prague by entrepreneurs Jan Kasper and Peter Zalesak, whose prior operating experience spans retail, ecommerce, energy, real estate, and agriculture. The firm remains anchored by an investment team that is majority former founders and operators. Its leadership structure places day-to-day capital deployment under Andrej Petrus, a Forbes 30u30 listee and Newton Venture Fellow who oversees the investment committee from Prague. The founding partners maintain visibility across 47 portfolio-affiliated companies across five countries, blending operator instincts with venture economics. The firm writes seed and pre-seed checks into tech startups in the US and Europe, with an explicit emphasis on Health & BioTech and Industrial Tech. Its portfolio of 92 names spans 15 sector filters on its website. Healthcare and life sciences account for roughly one-third of the disclosed book: confirmed positions include programmable mRNA delivery company ParcelBio, AI-based protein discovery platform DeepSeq.AI, single-cell simulation engine CellType, and CAR-T developer KiraGen. Outside biotech, ZAKA backs quantum hardware (Sygaldry Technologies), orbital fusion (Zephyr Fusion), robotics (Verne Robotics), earth observation (AxionOrbital Space), and battery manufacturing (Ateios Systems). The portfolio also contains direct fund investments, including exposure to B2B accelerator Startup Wise Guys. Geographically, the portfolio reaches 19 countries, with strongest density in the United States, Czech Republic, United Kingdom, Germany, and Slovakia. The firm maintains a Silicon Valley presence led by Filip Orth from Santa Clara University, who runs origination in the Bay Area. In May 2026, a significant portion of the team was on the ground in Palo Alto, Stanford, and San Francisco conducting founder meetings and relationship maintenance, reinforcing the US-Europe bridge model the firm markets. That same month, ZAKA participated in ParcelBio's $13 million seed round, led by Breyer Capital. The firm's website lists a minimum ticket size for outside investors of $130,000, suggesting a hybrid structure that may accept qualified limited partners alongside the general partners' own capital. ZAKA's key structural differentiator is its operator-founded, single-GP-committee architecture. Unlike many European seed funds built by former consultants or bankers, ZAKA's general partners — and most of its investment analysts — entered venture from company-building roles. That shapes a portfolio that spans from AI-native drug discovery to hotel SaaS without adhering to a single thematic silo. The absence of disclosed AUM or regulatory filings typical of larger EU managers further indicates a lean, proprietary capital base whose investment cadence is paced by founder judgment rather than a deployment clock.

Frequently asked questions

Who runs investment decisions at ZAKA?

Andrej Petrus leads the investment committee. A Forbes 30 Under 30 listee and Newton Venture Fellow, he joined ZAKA after experience in venture building and M&A and strategy consulting. He is based in Prague and is the principal decider on capital deployment.

How does ZAKA source proprietary deal flow?

ZAKA maintains an active Silicon Valley presence through Filip Orth, a Santa Clara University graduate based in the Bay Area, and conducts periodic multi-week team trips for founder meetings across San Francisco, Palo Alto, and Stanford. The firm's general partners also draw on their operating networks from sectors including retail, ecommerce, energy, and real estate.

Does ZAKA participate in fund commitments or only direct deals?

ZAKA does both. Its portfolio includes direct seed and pre-seed investments across 92 companies, as well as a fund investment in Startup Wise Guys, a B2B startup accelerator based in Europe. The blend suggests a willingness to gain exposure through both direct company equity and manager commitments.

What investment stages does ZAKA typically target?

The firm targets seed and pre-seed rounds in the US and Europe. Its deal flow spans early-stage through growth, with most disclosed activity concentrated at the earliest institutional entry points, often alongside or after accelerator programs and angel syndicates.

Which sectors does ZAKA concentrate on?

ZAKA explicitly highlights Health & BioTech and Industrial Tech as priority verticals, citing one of the best Healthcare & Life Sciences portfolios in continental Europe on its website. Beyond those, the portfolio reaches into space, quantum computing, AI, enterprise SaaS, hospitality, fintech, and mobility.

Where does the underlying capital come from?

The wealth source is not publicly disclosed. ZAKA's founding general partners, Jan Kasper and Peter Zalesak, built their own operating businesses in retail, ecommerce, energy, real estate, and agriculture across Central Europe. Whether the fund pools wholly proprietary capital or accepts external qualified investors at a minimum $130,000 ticket has not been definitively stated.

Is ZAKA structured as a family office or a traditional venture firm?

ZAKA operates as a seed and pre-seed venture capital fund from a corporate structure in the Czech Republic. Its mix of operator-founders, an investment committee, and a disclosed minimum ticket size for outside investors suggests a traditional VC architecture rather than a single-family office.
