Don't start a company in a space you're indifferent to and ignorant of. Your founding idea must be anchored in either deep domain expertise ("what you know") or a genuine, intense passion for the problem ("what you care about"). Lacking both is playing on "extra hard mode."

Since startups lack infinite time and money, an investor's key diligence question is whether the team can learn and iterate fast enough to find a valuable solution before resources run out. This 'learning velocity' is more important than initial traction or a perfect starting plan.

Spend significant time debating and mapping out a project's feasibility with a trusted group before starting to build. This internal stress-test is crucial for de-risking massive undertakings by ensuring there's a clear, plausible path to the end goal.

Unlike software, hardware iteration is slow and costly. A better approach is to resist building immediately and instead spend the majority of time on deep problem discovery. This allows you to "one-shot" a much better first version, minimizing wasted cycles on flawed prototypes.

Instead of searching for a market to serve, founders should solve a problem they personally experience. This "bottom-up" approach guarantees product-market fit for at least one person—the founder—providing a solid foundation to build upon and avoiding the common failure of abstract, top-down market analysis.

Maintain a running list of problems you encounter. If a problem persists and you keep running into it after a year, it's a strong signal for a potential business idea. This "aging" process filters out fleeting frustrations from genuinely persistent, valuable problems.

Don't jump straight to building an MVP. The founders of unicorn Ada spent a full year working as customer support agents for other companies. This deep, immersive research allowed them to gain unique insights that competitors, who only had a surface-level idea, could never discover.

A truly exceptional founder is a talent magnet who will relentlessly iterate until they find a winning model. Rejecting a partnership based on a weak initial idea is a mistake; the founder's talent is the real asset. They will likely pivot to a much bigger opportunity.

Instead of immediately hiring after validating his idea, the founder of Sure worked alone for a year. He used this time to secure the company's first critical insurance partner, ensuring the business was on stable footing before asking anyone else to leave their job and join the venture.
