Build a 13-Week Cash Flow View
Greg instructs founders to create a weekly-updated 13-week cash model that shows real cash movements.
Master Your Cashflow (Templates Included): https://startup-ideas-pod.link/money-map
On this episode, I share my simple financial operating system that helps me run my business. I share actual workflows that have saved one of my portfolio company from an 11-week runway crisis (when they thought they had 8 months), and the templates behind his 13-week cash tracker, Bear/Base/Bull decision framework, and one-page board report. This is a rare look inside the tactics I use to think about cash flow, dilution strategy, and building companies that don't run out of runway by accident.

Key Points
Your P&L lies about survival—one portfolio company thought they had 8 months of runway but actually had 11 weeks when mapped to real cash flow
The Bear/Base/Bull decision framework prevents emotional spending: if two-plus scenarios say no, wait (a $60K conference booth was rejected in bear case, approved two months later in bull case)
Acquisitions happen in 48 hours—keep a 10-file data room updated quarterly so you can respond to Tuesday emails with Wednesday meetings
Trust doesn't scale, policy does: weekly corporate card reviews caught an $8K personal ad spend in 7 days instead of 30
The system runs itself once built: 15 minutes Monday + 30 minutes Friday + 4 hours/month replaces heroic monthly scrambles
Every dollar raised costs ownership forever—cutting $40K/month burn has the same 12-month runway impact as fundraising but with 0% dilution
