Founder FAQ (Burn Rate Tactics)
Q: What is the absolute difference between Gross Burn and Net Burn?
Gross Burn is the total amount of cash your startup spends every month (salaries + rent + software + marketing). Net Burn is the "real" bleed: Gross Burn minus your actual cash revenue. If you spend $100k but make $40k, your Gross Burn is $100k, but your Net Burn is $60k. Net Burn is the only metric that determines your survival runway.
Q: How much runway do top-tier VCs actually want to see?
Standard VC wisdom dictates an 18-to-24 month runway after a fresh funding round. This gives you 12 months to hit your milestones and 6 months to close the next round before the "Fundraising Cliff." Having less than 6 months of runway is considered a "distressed" signal that destroys your negotiating leverage during term sheet discussions.
Q: Is it better to have a high burn rate if you are growing rapidly?
This depends on the "Burn Multiple" (Net Burn divided by Net New ARR). A Burn Multiple of 1.0x means you spend $1 to add $1 of recurring revenue—which is considered elite. If your multiple is 3.0x or higher, you are growing inefficiently. In high-interest-rate environments, investors shift focus from "Growth at all costs" to "Capital Efficiency," making high burn rates dangerous unless paired with exceptional unit economics.
Q: When should a founder officially pivot to survival mode (Default Alive)?
Paul Graham's "Default Alive" test is simple: If your revenue growth continues at its current rate, and your expenses stay flat, do you reach profitability before you run out of cash? If the answer is No, you are "Default Dead." You must either raise more capital immediately, cut costs drastically, or pivot your product to a higher-margin market.
Q: What are the first three expenses a startup should cut to extend runway?
1. Scale back non-core marketing spend (experimental channels that aren't yielding a clear CAC/LTV). 2. Consolidate or eliminate "SaaS Bloat" (unused seats and overlapping software tools). 3. Pause all non-essential hiring. While painful, a small, efficient team with 12 months of runway is far more valuable than a large, bloated team with only 3 months left.
