What SIVentures (prev. Smart Infrastructure Ventures) does

SIVentures (legal entity: Smart Infrastructure Ventures GmbH) is a Leipzig-based, early-stage venture capital firm focused on European B2B and digital-economy technology startups. The firm positions itself as a day-one institutional investor, committing up to €500k in initial capital and explicitly reserving capacity to participate in follow-on rounds, which it markets as a "value-add partner" relationship rather than a passive financial backer. Operationally it manages two fund vehicles — Smart Infrastructure Ventures Fund I GmbH & Co. KG and SIVentures Fund II GmbH & Co. KG — under a registered AIFM licence pursuant to section 2(4) of the German KAGB.

The portfolio comprises 18–21 disclosed companies spanning SaaS, legal-tech (LawX), energy-as-a-service (Einklang Energy), infrastructure software, and consumer-facing digital products; logged exits include Mogenius and Preventio, with the remainder marked Active. Deal flow is sourced primarily through the firm's structural partnership with the Spinlab accelerator ecosystem and supplemented by co-investment syndicates with sector-specialist funds such as Vireo Ventures and Motive Partners. The senior team consists of two General Partners (Björn Bauermeister and Dirk Frohnert) supported by a Principal, six Venture Partners, and additional team members, giving a headcount of 1–10.

The revenue model is standard for European seed-stage venture capital: the firm earns management fees on committed or invested AUM across its two fund vehicles and participates in equity upside through portfolio ownership that appreciates with company growth and exit events. Go-to-market is sales-led and relationship-driven — direct founder engagement and ecosystem referrals — rather than intermediated distribution.
