RTAventures VC (RTA.vc)

RTAventures VC (operating as RTA.vc) is a small Polish-German family office and early-stage venture capital firm founded in 2011, with offices in Warsaw, Poland and Berlin, Germany. The firm invests in online businesses with a particular focus on healthcare products, SaaS, marketplaces and tech-media-telecom verticals, backing companies primarily across Europe and selectively in the United States. RTAventures is co-founded by Piotr Kulesza, who serves as Founder and General Partner and has sat as Board Observer at Typeform, Investment Committee member at DocPlanner and advisor to Point Nine Capital, alongside co-founder Lubomir Jurczak. RTAventures prefers to invest approximately $1 million per direct deal into transactions with a maximum value of roughly $5 million, with 7 Seed rounds averaging $1.37 million and 4 Series A rounds averaging $4.06 million across the portfolio. Across 21 direct investments, the track record includes 1 unicorn -- DocPlanner, which reached unicorn valuation in 2021, eight years after RTA's first investment -- 1 IPO (Explain Everything) and 1 acquisition (Voxel). Other notable public portfolio names include Typeform, Booksy and Infermedica. Alongside direct investments, RTA.vc also participates as a limited partner in more than a dozen early-stage technology VC funds across Europe, and the firm has shifted its primary focus toward this fund-of-funds LP strategy. RTAventures' founder background and long-term portfolio relationships -- evidenced by an eight-year path to unicorn status with DocPlanner -- reflect a patient, conviction-driven investment philosophy that prioritizes company-building over quick markups. The Warsaw-Berlin base gives the firm access to two of Central Europe's most productive startup ecosystems for SaaS and health technology.
