Europe has deep technical talent, a regulatory environment that forces rigour, and founders who understand that building for the long term is a competitive advantage. The question is not whether Europe can produce world-class deep tech companies — it already does. The question is whether we back them at the pace the moment demands.
— Klaus GrössingerKlaus Grössinger is a General Partner at Onsight Ventures, a pan-European venture firm focused on early-stage investments in exponential technologies. With more than 16 years of experience in high-tech startup investments, technology transfer, and investment management, he brings both operational depth and strategic perspective to the companies he backs.
Before focusing exclusively on venture capital, Grössinger was the founder and CEO of a life sciences and chemistry research spin-off, giving him a founder's understanding of what it takes to commercialise science. He also serves as a lecturer at Universität Innsbruck and supports the regional innovation ecosystem through Investor*Innennetzwerk Tirol.
Onsight Ventures concentrates on what it calls exponential technologies — the sectors where breakthroughs in physics, biology, and computing converge to create step-change rather than incremental improvement. The portfolio spans quantum computing, synthetic biology, and advanced computing and semiconductors, with a deliberate focus on companies where the science is non-trivial and the moats are structural.
The firm was co-founded in 2021 together with Jasmin Güngör as a spin-off from the Hermann Hauser Family Office. For Grössinger, the investment thesis is rooted in a conviction that Europe's scientific base — long undervalued by capital markets — is precisely the foundation on which the next generation of global technology companies will be built.
Grössinger is a vocal advocate for patient capital in sectors that require long development cycles. Where many funds look for fast growth metrics and quick returns, his approach centres on understanding the underlying science and backing teams with the credibility to navigate from laboratory breakthrough to market deployment. In his view, the dual-use dimension of many deep tech sectors — where civilian and defence applications share the same technology base — is one of the defining features of the current innovation cycle, not a complication to be managed away.
