Alex Hartz is a partner at Shine Capital who brings an unusual combination of deep technical training in applied physics from Caltech and eight years of venture experience at SciFi VC, where he developed expertise in embedded lending and credit infrastructure. His background spans hands-on photonics research and building fintech investment practices, making him particularly suited for founders building technically complex financial products who want an investor comfortable with both rigorous science and market realities.

• Strong interest in financial infrastructure and embedded lending solutions that modernize legacy systems. He frequently highlights companies that improve capital access or update backend servicing, such as Peach Finance for loan management and Capchase for startup liquidity.
• Deep conviction in hard sciences and complex engineering challenges, particularly in energy and biology. This is evident in his enthusiasm for Antares Nuclear receiving safety approvals for their reactor and his support for EmulateBio using human cells to improve drug development.
• Appreciation for ambitious founders who demonstrate clarity of thought and the ability to pivot successfully. He praised the Brex team for shifting from virtual reality to fintech and commended the leadership at Antares Nuclear for being exceptionally clear and creative.
• Focus on applied artificial intelligence that solves specific data structuring and visibility problems. For example, he promoted Supergood for helping feed real-time information into language models and BinIt for using computer vision to track materials in the recycling industry.
• Support for platforms that empower individual workers or consumers to lower costs and increase independence. He championed CloudTrucks for helping drivers earn more and Aven for aiming to reduce the cost of capital for consumers.
