Day1

Four players experience an AI-generated startup journey through asymmetric information and conflicting roles.

A startup is not a search for the correct answer. It is a group of people making commitments with incomplete information.

Entrepreneurship is usually presented through successful cases, frameworks, and explanations written after the outcome is known. Actual company building happens before that certainty exists: technology, market, capital, and team problems arrive together; different roles possess different information and interpret the same choice in different ways.

Day1 turns that process into a four-player startup simulation. Players do not observe the story of a company from outside. They become its CEO, CTO, CMO, and COO, discussing and choosing within business situations continuously generated by AI—and sharing the consequences of those decisions.

One Company, Four Realities

Every role belongs to the same company but encounters a different reality:

the CEO sets direction and bears the pressure of final decisions and team relationships;
the CTO weighs technical feasibility, development speed, and system stability;
the CMO interprets market windows, competitors, and user response;
the COO confronts cash, costs, resources, and operational constraints.

Each round presents one public event, while every player receives private information specific to their role. What appears to one person as a growth opportunity may look like technical risk or a cash crisis to another. The central activity is therefore not individual problem-solving, but the way a team exchanges information, persuades one another, and reaches a collective decision.

AI as a Dynamic Game Master

The game begins with a startup idea proposed by the players. AI expands it into a concrete product, target users, initial team conditions, and market environment. It then generates new events, choices, and role-specific information as the company progresses.

Five rounds move through product validation, market research, technical development, launch, user acquisition, expansion, and financing. The team's decisions become context for what follows. AI evaluates both positive and negative effects, allowing the story to develop from the players' trajectory rather than from one predetermined script.

The Outcome Is a Decision History, Not a Score

The final startup report traces causality across the rounds. It describes what became of the company and how each team member's path might continue. An ending may be a partial success, a costly pivot, or a failed main project that still leaves behind capabilities and new opportunities.

Day1 does not attempt to teach a standard answer to entrepreneurship. It creates a low-risk narrative sandbox where players can experience role division, asymmetric information, resource constraints, and team negotiation—and observe how a sequence of local choices collectively shapes the fate of a company.
