Sisu Game Ventures

Day-to-day investment decisions sit with the partnership group led by Founding Partners Samuli Syvähuoko and Paul Bragiel, alongside General Partner Erik Gloersen, who joined in 2020. The firm operates a flat partner structure with no separate investment committee disclosed. Venture Partners Kalle Kaivola and Moaffak Ahmed contribute deal sourcing and portfolio support, while Principal Jere Partanen handles pipeline operations; final check-writing authority rests with the founding and general partner tier.

Sisu’s sourcing model relies on the operator networks of its partners — every partner is a former studio founder or CEO with decades of Nordic game industry relationships. The firm also runs the “Sisu Family,” a curated collective of portfolio founders and co-investors that shares deal referrals and due diligence informally. Additionally, partners maintain overlapping networks through adjacent vehicles like GameFounders, Nordic Makers, and the Slush conference ecosystem, which surfaces early-stage Nordic and Baltic studios before they reach broader venture markets.

Sisu is a direct-investment venture fund that writes equity checks into individual game studios and games-adjacent technology companies. There is no public record of Sisu acting as a limited partner in other venture funds or operating a fund-of-funds allocation. The firm’s capital deployment focuses exclusively on direct seed and early-stage equity rounds, occasionally alongside co-investors from its partner network. Parallel partner vehicles like Bragiel’s Presence Capital and Savannah Fund are structurally separate and do not represent Sisu fund commitments.

Sisu targets pre-revenue and pre-product startups, positioning itself as the first institutional check — a stage it calls “first money in, pre-revenue and most often pre-product.” This typically corresponds to pre-seed and seed rounds in the $0.2M–$2M range based on Nordic gaming standards, though the firm does not publish a standard check-size range. Sisu retains capacity for follow-on investments into growth rounds through its fund structure, as demonstrated by multi-round participation in incubated companies like Lightheart Entertainment.

Sisu is a single-sector fund — it invests only in games and games-adjacent technology and does not allocate to fintech, enterprise SaaS, climate, health, or other generalist venture categories unless they explicitly serve the game development stack. Within games, the firm has not publicly excluded any subcategory — its portfolio spans mobile, PC/console, cloud-native, and AI-augmented game development — but its operator-heavy team biases decision-making toward studios building original IP rather than work-for-hire or middleware-only businesses.

Per its own disclosure, Sisu’s investors are primarily individuals and a limited number of game companies from the Nordic and European game industry. The firm has not published a formal LP list or disclosed institutional anchor investors, which is consistent with an early-stage venture fund raising on a deal-by-deal or small-fund basis from a network of high-net-worth games entrepreneurs rather than from pension funds or fund-of-funds. No sovereign wealth, endowment, or family-office anchor has been publicly identified.

The Sisu Family is an informal portfolio-network construct, not a separate legal entity or revenue-generating business. It functions as a knowledge-sharing collective among Sisu’s 60+ portfolio companies, co-investors, and strategic partners — the firm describes collaboration, founder-to-founder problem solving, and deal referrals as core to the model. There is no membership fee or public charter, distinguishing it from formal founder communities like YPO, Tiger 21, or R360; it is better understood as Sisu’s proprietary value-added layer bundled with its equity investments.
