The core message of the provided transcript is that volatility can be a structural advantage for startups, not merely a threat to manage. The speaker, the CEO of Sanity Group, frames the masterclass around what founders can learn from building in unstable markets, especially regulated ones like medical cannabis. After the host introduces him as leading a premium medical cannabis healthcare brand in Europe, he corrects the business figure from €25 million to $250 million and clarifies that the session is not a company presentation. Instead, he promises practical lessons from almost twenty years as a startup founder, with Q&A reserved for cannabis, regulation, politics, Germany, and broader startup questions.
