Burn Rate

In Kyle’s notes, burn rate surfaces as the variable a manager is willing to tolerate when conviction about market size is high. The TAM Arbitrage lesson — drawn from Coatue’s practice — holds that doing the work to understand a market better than anyone else lets an investor “pay higher prices and tolerate more burn.” The framing treats burn not as a fixed danger to minimize but as a dial you can turn up when you understand the prize is bigger than the market appreciates.

Context: Burn rate is the pace at which a startup spends cash (its monthly net cash outflow) ahead of profitability, typically expressed alongside “runway” — the number of months of cash remaining at the current burn. It is a core operating metric in venture-backed company building.
