Behind the Deals: What Battey Investors are Looking For

In this episode, we dive deep into the high-stakes world of battery venture funding with one of the field’s most respected voices — Dr. Billy Wu. As an expert in battery technologies and a trusted technical due diligence advisor for venture capital firms, Billy Wu occupies a unique vantage point at the intersection of cutting-edge battery science and investment strategy.

What makes a battery startup worth funding? According to Dr. Wu, it's never just hype or a flashy demo. The real story lies in the data: energy and power density, chemistry stability, cost of materials, manufacturing scalability, cycle life, and charging speed — all have to align to form a compelling business case. Billy Wu breaks down how he evaluates this critical data and helps investors separate promising innovation from overpromised vaporware.

But he also sees things from the other side. Having worked directly with startups, Billy Wu understands the technical and commercial pressures founders face when pitching to investors. He shares what early-stage companies often overlook in their funding narratives and how better communication of their tech performance could turn a “maybe” into a strong investment case.
