Scaling up sustainable aircraft is like scaling up nuclear power—a comparable challenge in terms of regulatory obstacles, timelines, and the weight of responsibility. At least, that’s how it seemed to me, looking from the outside. I was sure that the climate tech community could learn many lessons from the aviation startup experience, so I’ve asked an expert.
I’ve just finished recording the next episode of WattsUpWithStartups with Dirk Singer, aviation expert, book author and consultant. Dirk spent decades working in the aviation industry and has seen startups rise and fall. Here are some of the questions we covered:
1. Why does aviation take so much time to scale?
2. How much money do you need to go from idea to full order book, like Airbus?
3. Which technologies might disrupt traditional aviation?
4. What investors are looking for when investing in sustainable aviation startups?
5. Lessons learned from successful and failed aviation startups.
This episode will be completely packed with insights! Whether you are working in the sustainable aviation industry, batteries, or circular materials, you will recognise a lot, learn a lot, and have fun while watching it. I will be publishing it in a few weeks, so stay tuned and catch up on previous episodes!
