This episode of The Startup Vagabond is a conversation with Karin Andrea Stephan, co-founder of Sidekick Platform, about trusted knowledge, human expertise, AI, and what happens when the internet becomes one giant summary machine.
Karin’s background is not a straight-line startup story. She started as a professional musician, moved into organizational psychology and digital transformation, built and sold Earcake to Alumia Health, and now works on Sidekick Platform from Zurich and Silicon Valley.
Sidekick Platform turns expert content into conversational AI channels. Instead of asking a generic AI model for an answer pulled from the open internet, users can interact with curated knowledge from specific experts, creators, scientists, institutions, books, podcasts, videos, and archives — with the ability to trace the answer back to the original source.
We talk about why that matters in high-stakes environments like health, education, business, and personal decision-making. AI can make knowledge easier to access, but it also creates a problem: summaries of summaries of summaries, stripped of context, nuance, and original expertise.
Karin calls this the “AI soup.”
We also get into the future of creators and expert brands, why earned expertise is becoming more valuable, how Sidekick is being used by students, veterans, health organizations, psychedelic wellness groups, and education platforms, and what startup founders can learn from both Silicon Valley and Switzerland.
The broader takeaway: AI will not replace human expertise. But experts, creators, and institutions need better ways to make their knowledge searchable, trustworthy, conversational, and directly accessible.
