TL;DR

Founders with deep domain expertise should trust their gut more, while those new to an industry should prioritize validation, preventing founders from either overspending on unproven ideas or under-leveraging their knowledge.

Key Insights

1

Founders who have previously built valuable, adopted internal tools or popular consumer products possess a level of taste and expertise that warrants trusting their gut more heavily.

2

When founders lack deep industry experience or strong personal opinions about what to build, they should lean on external validation and be open to building expertise in a chosen area.

3

The 'Steve Jobs' extreme of trusting your gut involves talking to no one and relying solely on internal vision, while the opposite extreme involves passively waiting for others to dictate the product idea.

4

A founder with 10 years of experience in mortgage underwriting, for example, should trust their 'gut' about what those professionals need, as opposed to a novice who has only bought a house.

5

A common pitfall is when founders with expertise become fearful and act like novices, or when novices become overconfident and dismiss the need for extensive validation.

6

Instead of seeking external validation, founders with expertise are sometimes dissuaded by fears of market acceptance or the perceived need to incorporate trendy technologies like AI, even if it conflicts with their domain knowledge.

Leveraging expertise to trust your instincts

Founders who possess significant expertise in a specific domain, especially if they have a track record of building valuable and adopted products internally or in previous ventures, should feel empowered to trust their gut more than those without such experience. This is particularly true if you've solved your own problem and know first-hand the nuances and needs of a market. Consider a founder who built a critical tool within a large company that is still in use after they've left; this individual likely has a deep understanding of the problem space and a well-developed taste for what works. Similarly, if you've successfully launched a consumer product, you understand the lifecycle and market dynamics involved. In these scenarios, listening to your instincts about what to build, how to refine it, or what features are essential can be a significant advantage, potentially impressing yourself with the quality and utility of the product.

When gut feelings may be unreliable

Conversely, if you find yourself without strong opinions on what to build, or if your preferences align closely with the mainstream average, your gut instincts might not be a reliable guide. This often occurs when founders have had high-level roles without deep dives into specific topics or have limited work experience. In such situations, the primary goal is to build expertise within a chosen area. The advice here is to start with a broad, promising idea space, remain open-minded, and avoid overly rigid plans. This approach allows for learning and discovery as you progress. It's crucial to select an area you're genuinely interested in learning about, as the process will inevitably involve significant learning, and choosing a field you dislike purely for fundraising potential is rarely a sustainable strategy.

The spectrum of trusting your gut: extremes and balance

The decision to trust one's gut exists on a spectrum, with two extreme scenarios often cited. On one end is the 'Steve Jobs' archetype: a founder who famously avoided extensive customer input, believing their vision alone could create revolutionary products like the iPhone. This approach involves minimal external validation and maximum reliance on internal intuition and taste. At the opposite end is the 'mom test' extreme, where a founder believes they know nothing and passively seeks all ideas from others, completely disregarding their own instincts. While both extremes are presented as caricatures, they highlight the tension between internal vision and external feedback. The key is to find a balance informed by your specific circumstances, rather than defaulting to either absolute reliance or complete abdication of personal judgment.

A concrete example: mortgage underwriting software

To illustrate the difference, consider a startup idea for mortgage underwriting software. If the founding team includes individuals with 10 years of experience as real estate agents or building software within mortgage underwriting companies, they possess invaluable domain expertise. Their 'gut feel' about what underwriters need is likely accurate due to their direct experience, exposure to existing solutions, and understanding of market frustrations. They should trust this expertise when developing their product. However, if the founders have no prior industry experience—perhaps they are only interested because they recently bought a house—their intuition about the specific needs of mortgage underwriters is far less reliable. While they can still succeed, they must approach the problem with less confidence in their pre-existing knowledge and prioritize extensive validation and learning.

Common founder missteps in trusting gut

A frequent error occurs when founders misjudge their own position on the expertise spectrum. Founders with deep knowledge may become overly fearful, doubting their insights and acting as if they need extensive validation, much like novices. They might worry that their valuable internal tools won't be desired by others, or that their ideas aren't fundable by venture capitalists. This can lead them to, for instance, build an AI product because it's trendy, rather than the practical solution they know is needed, simply to appease investor expectations. On the flip side, inexperienced founders can become overly confident, planning for extensive development timelines and complex solutions as if they possessed deep industry insight, neglecting the importance of building a minimal viable product (MVP) to learn quickly.

The value of self-honesty and personalized advice

Ultimately, the most effective approach involves self-awareness regarding your level of expertise. If you have significant experience, trust your instincts to a greater extent, focusing on building something that impresses you. If you are new to an area, admit this to yourself, start simply, and commit to learning on the fly. The goal is not to advocate for one path over another but to encourage founders to consciously assess whether they are bringing expertise or building it, and to tailor their strategy accordingly. This personalized approach, as practiced in one-on-one settings like Y Combinator office hours, highlights the difficulty of providing one-size-fits-all advice and the importance of customized guidance for each founder and startup situation.

When to Trust Your Gut as a Startup Founder

Practical takeaways from this episode

Do This

Trust your gut if you have deep expertise in the problem domain or have previously built successful products.
Build something that would impress you and solve a problem you've personally experienced.
If you lack expertise, focus on building it by entering a valuable area and starting simply with an MVP.
Choose an area you're excited to learn about, especially if you need to build expertise from scratch.
For founders with expertise, follow your instincts, even if it means not explicitly including AI if it's not core to the solution.

Avoid This

Don't blindly trust your gut if you have little to no opinions or your opinions are mainstream and indistinguishable from the average person.
Avoid acting overly confident if you lack industry experience; focus on learning and validating ideas through user feedback.
Don't ignore your expertise because you think investors only want to fund 'AI' projects.
Avoid overly complex, comprehensive plans if you're building expertise; start small and iterate.
Don't choose an area to build a startup in solely because you think it will raise money if you hate the area and lack passion for it.

Common Questions

Founders should trust their gut when they possess deep expertise in the problem domain, have a track record of building valuable products, or have developed strong, discerning taste through experience. This often applies when solving their own problems or creating something that would impress them personally.
