WHAT NEW FOUNDERS GET WRONG IN THEIR ELEVATOR PITCH
so hey - am writing this in the FINAL week before applications close for a16z speedrun 6. The deadline Sep 28, this upcoming sunday. Speedrun is a16z's new program to invest up to $1M in brand new startups, with a 12-week

Revenue talks. Pitch theatre is PowerPoint therapy.
Real founders answer emails at 11 PM, not perfect slides.
If customers won't interrupt lunch for your thing, no demo fixes that.
🥪 Ship during lunch. Skip storytelling.
🚀 Stop bouncing between concepts. Lock onto one that clicks.
Then push it ahead with a single action:
Sketch out the basic mechanics on paper
Call someone in the target market for their honest take
Build a bare-bones landing page to capture interest
Run the numbers on your phone calculator
Zero pressure to perfect-just permission to begin.
📈 Momentum builds through tiny steps, not giant leaps,
Mr. Juice
