The speed and completeness of a founder's communication can be a powerful indicator of their dedication. Unlike the typical shorthand from busy people, a founder who replies quickly with depth demonstrates an all-consuming passion and singular focus on their business.

VCs with operational backgrounds value execution over credentials. They screen for founders who show an instinct to act and build immediately, such as launching a splash page to test demand, before raising capital. This "dirt under the fingernails" is a stronger signal than pedigree.

A person's success and their response time are strongly correlated. Highly effective individuals like Sam Altman respond incredibly quickly, despite being exceptionally busy. A slow response time is a "huge turnoff" and can be a negative signal for founders, suggesting a lack of energy or prioritization.

An investor can gauge a founder's depth by their preparedness. If a VC's questions during a 60-minute pitch reveal strategic holes the founder hasn't already considered, it's a strong negative signal about their level of obsession and foresight.

While product and market are crucial, the most important factor in an early-stage bet is the founder. This is because most startups pivot significantly. A resilient, adaptable founder who can execute through change is more valuable than a perfect initial idea, leading to the ranking: Founder > Market > Product.

Contrary to the belief that success is measured by rapid email responses, the most important people for a founder to be responsive to are their own team. Prioritizing internal communication channels like Slack over an external email inbox ensures the team has the support it needs to execute effectively.

The most exceptional founders are so intensely focused on building their business that they deprioritize non-critical communication, even with investors. Their slow response time is a counter-intuitive signal of extreme dedication and focus, not disrespect.

In early-stage investing, the quality of the founder can be more important than the initial business concept. A strong founder is seen as someone who will eventually find success, even if the first idea requires a pivot.

When a CEO consistently emails on nights and weekends, it's a clear signal of a high-intensity work culture with low work-life balance. For candidates, this isn't just about the CEO's schedule; it's a cultural red flag or green flag depending on their own work preferences and expectations.
