Zeal Ventures
Zeal Ventures, led by Dr. Stefan Tweraser, invests ZEAL Network's corporate balance sheet in lottery and prize-led gaming startups across Europe.
Zeal Ventures
Zeal Ventures was founded in 2017 as the investment arm of ZEAL Network SE, the Hamburg-based lottery operator that originated as Tipp24. Jens Schumann and Marc Peters co-founded the parent company, which today trades on the Frankfurt Stock Exchange and provides the venture unit with strategic and operational backing. Unlike a classic family office, the capital source is a listed entity — creating a hybrid investment vehicle that deploys corporate balance-sheet capital rather than personal family wealth. The firm targets early-stage and growth investments across the lottery, prize-led gaming, and digital entertainment ecosystem. It has committed to 10 businesses since inception and currently holds five active positions. Confirmed portfolio companies include UK-based prize draw platform DAYMADE and Swedish iLottery operator Random State — the latter structured as a co-investment with FDJ United Ventures. Zeal Ventures covers Europe as its primary geographic footprint, with deal activity observable in the UK, Sweden, and Germany. The firm participates in both direct equity rounds and co-investment structures, often alongside other strategic lottery and gaming investors. Dr. Stefan Tweraser serves as CEO, with Juliane Gutsmiedl and Amit Lakhani leading deal execution as Investment Directors alongside Investment Manager Henrik Mai. The parent company, ZEAL Network, maintains its headquarters at Strassenbahnring 11 in Hamburg and joined the World Lottery Association in April 2023 and the Deutscher Online-Casinoverband in April 2025 — industry memberships that provide the venture team with regulatory and market intelligence. In 2025, ZEAL and FDJ United Ventures announced they were open to future investment collaborations following the Random State co-investment. The group also operates two philanthropic programs, freiheit+ and Traumhausverlosung, both linked to the parent company's consumer-facing operations. Zeal Ventures' structural differentiator is not its stage mandate but its sponsor. It functions as a corporate venture capital unit drawing permanent capital from a publicly listed lottery operator, which means its portfolio companies gain privileged access to ZEAL Network's technology stack, regulatory licenses, and customer distribution channels across Europe. The firm is one of the few dedicated institutional investors globally focused exclusively on re-architecting the lottery vertical — moving it from legacy draw-based models to interactive, prize-led digital experiences.

Frequently asked questions
Who runs investment decisions at Zeal Ventures?
Dr. Stefan Tweraser is the CEO of Zeal Ventures. The investment team includes Investment Directors Juliane Gutsmiedl and Amit Lakhani, and Investment Manager Henrik Mai. The firm operates under the strategic umbrella of ZEAL Network SE, whose Supervisory Board includes parent-company co-founders Jens Schumann and Marc Peters.
Is Zeal Ventures structured as a family office or a corporate venture arm?
Zeal Ventures is a corporate venture capital unit backed by ZEAL Network SE, a publicly traded European lottery operator. It is not a single-family office and does not manage personal wealth. The capital deployed comes from ZEAL Network's balance sheet, making it a strategic corporate investor in the lottery and gaming space.
What investment stages does Zeal Ventures typically target?
The firm targets early-stage investments, including seed and start-up rounds, as well as growth-stage companies. Since its founding in 2017, it has backed 10 businesses and maintains an active portfolio of five.
Which sectors does Zeal Ventures invest in, and are there any it explicitly avoids?
Zeal Ventures is exclusively focused on lottery, prize-led gaming, and digital entertainment. It explicitly targets companies redefining the lottery experience. There is no evidence it invests outside these domains; its mandate is tightly coupled to verticals adjacent to ZEAL Network's core lottery operations.
Does Zeal Ventures participate in fund commitments or only direct deals?
Zeal Ventures operates through direct equity investments and structured co-investments. A documented example is its co-investment with FDJ United Ventures in Swedish iLottery operator Random State. There is no public record of the firm committing capital to third-party funds.
How does Zeal Ventures source proprietary deal flow?
Deal flow is generated through ZEAL Network's deep industry position in European lottery markets and its memberships in the World Lottery Association and Deutscher Online-Casinoverband. The parent company's operating relationships with national lottery partners, such as Spain's ONCE, provide additional proprietary sourcing channels.
What is Zeal Ventures' known posture on co-investments alongside external GPs?
The firm co-invests alongside strategic corporate partners rather than financial sponsors. The Random State transaction with FDJ United Ventures is the clearest example, and the two groups announced in 2025 that they are open to future investment collaborations in the iLottery space.
