Startup success

The finals of the Laser World of Photonics Startup and Innovation Awards, which Electro Optics is sponsoring, would have taken place this month. The event is now happening next year, and I’m probably not alone in being eager to visit Munich and other destinations soon to meet familiar faces in person again. We have articles in this issue discussing

these themes. On page 4, David Giltner asks whether scientists can make good entrepreneurs, arguing that the perception of a successful startup leader is different from the qualities required, in reality. Géraldine Andrieux, of accelerator Blumorpho, shares tips on getting investors’ attention on page 8. Being able to pitch sharp and smart is part of what is expected from an entrepreneur, but presentation skills are just part of what makes a pitch successful, she argues. Healthy levels of investment are key to a successful startup ecosystem, and is something Epic is advocating for, particularly after photonics was not named in the European Commission’s funding programme, Horizon Europe. Matthew Dale, on page 10, reports of the association’s AGM which took place remotely in April, where the development of a Core Photonics Index was discussed. It is hoped the index will demonstrate that photonics is a profitable industry worthy of investment.
