Quantum startups require patient capital and investors who can navigate both complex science and long development cycles. In this session, Qolumbus co-founder Frédéric Attia and business angel Christian Van Gysel share their two perspectives on building and backing a quantum company. Using the concrete case of Qolumbus’s first round, led by business angels from the Paris-Saclay ecosystem, they will discuss how they assessed the opportunity, structured the deal and organised support beyond capital. The conversation will then explore the next steps with growth investors: what these follow-on investors expect to see, how to prepare a quantum startup for growth, and how founders and angels can work together across ecosystems to secure the right capital at the right time
