## Resource

Jan Henrik Leisse explains how eleQtron secured a massive €57 million Series A despite the lack of immediate commercial use cases. The discussion explores the transition from hardware development to building a scalable quantum computing ecosystem.

## Highlights
- Main idea: Quantum computing is moving toward a 'computing time as a service' model, similar to classical cloud computing
- Practical takeaway: Success in deep tech requires focusing on scalable systems and reliability rather than just chasing scientific world records
- Strategic insight: Early revenue can be driven by selling hardware to strategic partners like research centers to build a foundation for future use cases
- Failure mode: Avoiding the trap of focusing solely on interesting research projects at the expense of product-market fit and structural scalability
- Investment thesis: Large-scale deep tech requires a combination of public anchor investments and private venture capital to sustain long-term development

## Topics

Quantum Computing, Series A Funding, Deep Tech, Hardware Development, Venture Capital, Scalability, Quantum Ecosystem, Tech Entrepreneurship
