The Term Sheet Explainer

Explain this investment term sheet in plain English and tell me what
actually matters.

The term sheet: [PASTE OR DESCRIBE THE KEY TERMS]
The context: [ROUND, AMOUNT, STAGE]

Provide:
1. What each major term means, plainly (valuation, option pool,
   liquidation preference, board, vesting, anti-dilution, pro-rata)
2. The terms that matter more than the headline valuation
3. Where the economics and control really get decided
4. The terms to push back on and reasonable asks
5. The clauses that could hurt me later that look harmless now

Be clear this is to help me understand and negotiate — the actual document
needs a startup lawyer, and I should get one. Flag the terms that most
affect my outcome.
