When venture capitalists are asked why their investments fail, they point to the team more than anything else. In the largest study of how VCs actually decide (Gompers, Gornall, Kaplan and Strebulaev, a survey of 885 investors), 55% named the team as the single most important factor in their failed investments, and 95% called it an important factor, ranking it above product, market, and timing. They attribute both success and failure to the team more than to the business itself.
It is not only the investors' view. Across Noam Wasserman's study of roughly 10,000 founders at Harvard Business School, the leading category of startup-killing problems is people problems, cofounder tension, equity disputes, role confusion, and missing skills, rather than product or market (HBR, 2008).
Yet team diligence is one of the most under-tooled decisions in venture. Most studios, accelerators, and early-stage investors evaluate teams the way they did thirty years ago, with interviews, references, and pattern-match intuition. That works some of the time. The failure data says it does not work often enough.
One venture studio director put the gap plainly. You can run every interview, he told us, and “everybody's like, yeah, it's all great,” then you pair people up and “this isn't working.” He had hired people who interviewed “all great” and were gone in ninety days, “wasting time and money.”
Tellstone exists to give that decision a measurement layer.
