This paper presents a summary of key insights for startups, derived from a lecture by Michael Seibel, co-founder of Twitch and CEO of Y Combinator, titled "<Everything We Teach at Y Combinator in 10 Minutes>". The content distills Y Combinator's two decades of experience in nurturing startups. The core methodology detailed focuses specifically on the foundational aspect of team composition.

According to the summary, an optimal startup team should adhere to the following principles:

1. Team Size: The team should ideally consist of 2 to 4 co-founders.
2. Skillset Distribution: At least 50% of the co-founders must possess development skills, indicating a strong emphasis on technical capabilities within the founding team.
3. Financial Preparedness: All co-founders are required to have secured at least one year's worth of personal living expenses. This financial buffer is explicitly defined as funds sufficient for basic subsistence, characterized as "ramen-eating money," rather than for maintaining a comfortable or high-end lifestyle. This requirement aims to mitigate immediate financial pressures, allowing the team to focus intently on product development and business growth without the distraction of seeking quick personal income.
