About Stefan Tirtey

Stefan Tirtey co-founded CommerzVentures and has spent 15+ years investing in early-stage fintech, personally leading investments in companies like Marqeta, eToro, and Mambu with a focus on payments infrastructure, cloud banking, and financial security rather than general fintech. He specifically seeks founders who can articulate clear plans for market domination and has built a reputation for backing global, infrastructure-like fintech platforms that can scale across borders rather than country-specific consumer applications.

Avg Check Size

CommerzVentures is an independent venture capital firm spun out from Commerzbank that specializes exclusively in fintech, insurtech, and Climate FinTech, with the same small team of experienced VCs personally co-investing in every deal across their Series A/B rounds of €2-10 million.
