From my experience at spectup working with startups across various sectors, and drawing from my background at N26 and Deloitte's Innovation & Ventures team, I'm seeing incredible potential in sustainable technology and circular economy businesses. During my time at BMW Startup Garage, I noticed a significant shift in how mobility and sustainability intersected, with some of the most promising startups focusing on green tech solutions. I'm particularly excited about the convergence of AI and climate tech - it reminds me of how fintech transformed banking, which I witnessed firsthand at N26. Just as the tech boom of the '90s was driven by internet infrastructure, I believe the next wave of billion-dollar opportunities will come from companies solving climate challenges using advanced technology. At spectup, we're already seeing increased investor interest in startups working on energy storage solutions, carbon capture technologies, and sustainable manufacturing processes. However, it's crucial to note that unlike the '90s tech boom, these emerging sectors are driven by urgent global needs rather than pure speculation. Through our work with various startups, we're noticing that investors are particularly interested in companies that combine technological innovation with clear environmental impact - they're looking for the next Tesla, not just the next tech unicorn.
