Investor Insight Session #4 – Marvelous.

From Lab to Pitch: How deep tech investors decide

Deep tech startups play by different rules: longer development cycles, hardware risk and markets that may not exist yet. So how do investors decide whether to back a team at pre-seed? At our next Investor Insight Session, Jannis Duckek from Marvelous joins us at the JUNI Campus to share how a deep tech VC looks at early-stage founders.

Marvelous is a Berlin-based pre-seed and seed VC investing in deep tech hardware. Jannis works with the fund as Founders Associate and is also a PhD candidate at the European Research Center for Information Systems (ERCIS) at the University of Münster, where he researches climate deep tech startups and their value propositions. He also mentors early-stage founders in deep tech and green chemistry on fundraising, business models and pitching.

New this time: Live Pitch Feedback
We’re changing up the format. After a short input from Jannis on what Marvelous looks for, three startups get to pitch directly to him and receive honest, on-the-spot feedback. Want to be one of them? Just say so in the registration question when you sign up. We’ll reach out to the selected teams in advance.

For everyone else, it’s a rare look at how an investor reacts to a real pitch, followed by an open Q&A where you can bring your own questions: When is a deep tech idea ready for a VC conversation? How much proof does the technology need? What makes a pitch stick, and what makes it fall flat?

Whether you’re a researcher, a PhD candidate thinking about spinning out, or a founder preparing your first round in GreenTech, BioTech or Life Sciences, this session is for you.
