1. VALIDATE DEMAND: The Core Risk

Demand is the biggest risk in every business. You don't create it; you find it by observing what customers are trying to accomplish.
The goal is to find as many people to pay you as soon as possible. Validate demand so you don't waste time on an unviable idea.
The truth about demand is found in sales calls and conversations with customers, not in structured, theoretical validation interviews.
Pivot from the demand side, not the supply side (what the market wants, not what you merely can build).
Commercialize early. If your product development is expected to take a long time, it's even more important to secure interest before you build.

2. EMBRACE THE MINDSET: Execution & Resilience

Building a company is an execution game. Velocity and focus on the few things that matter are your only competitive advantages.
The founder is the chief branding officer of the company. You are also a salesperson by profession, and rejection is guaranteed.
Work in weeks, not months. Prioritize and act now; it is always better to do it now than later.
Loneliness will creep in; actively seek peers, even if they are competitors, to share the journey and big emotions.
Be selfish as a founder: when making major decisions, ensure they benefit the customers, employees, and yourself.

3. FIND YOUR CO-FOUNDER: The New Moat

AI tools have lowered the barrier of entry for startups. Building speed is no longer the key moat because everyone can move fast.
When everyone can build quickly, the differentiation is the founder and the specific expertise they bring.
The New Moats in the modern era are: Deep Integration, Taste and Point of View, Trust and Community, and Specialization.
Someone can copy your code, but they cannot copy your obsession. This is the core quality to look for in a partner.
Attract the right people to build a high density of highly talented people from day one. This starts with your co-founder.

The Missing Piece: Trust and Community

Your technical co-founder is not just a coder. They are half of your differentiation. Building a startup in the AI era requires a new moat: a deep, committed partnership based on Trust and Community. Do not search for a skill set; find an obsession.
