JJ Kasper describes himself as a "previously disgruntled academic, failed attorney, reformed consultant, retired turnaround guy, wistful musician, and reluctant VC," reflecting an unusually non-linear path that founders tend to remember and relate to. He uses a consulting-style, case-interview approach to evaluate founders where their own business becomes the case, and he probes how they think and reason under uncertainty rather than relying on hype or superficial pattern-matching.

• Focus on verified financial substance over vanity metrics. He draws a sharp distinction between reaching a high revenue number and achieving that milestone with audited, compliant financials, suggesting he digs deep into the legitimacy of a company's performance rather than just accepting topline growth.
• Skepticism toward market hype and bandwagon investing, particularly regarding artificial intelligence. He has poked fun at peers who become instant fanatics about the latest tech trends and stop thinking critically, indicating he values founders who stay grounded rather than chasing the current buzz.
• Appreciation for capital efficiency and founders who are wary of over-reliance on venture funding. He shared a memory of an entrepreneur who compared venture capital to a drug and vowed to take as little as possible, framing this mindset as a positive trait rather than a lack of ambition.
• Distaste for overly complex financial engineering and legal structures. He has mocked the absurdity of multilayered investment vehicles used for hot companies like SpaceX or Anthropic, implying a preference for clean, straightforward deal structures without unnecessary friction.
• Attention to etiquette, presentation, and attention to detail. He frequently comments on a lack of standards in modern behavior, such as using cutlery incorrectly or dressing poorly, which suggests that a founder's polish and ability to adhere to traditional professional norms could influence his perception of their competence.
• Value for hard work and a rejection of premature leisure. He expressed annoyance at colleagues setting holiday away messages as early as mid-December, signaling that he respects a relentless work ethic and may look down on founders or investors who check out too early.
