Episode notes
Do Everything Yourself Early
- If you run a small business alone, handle all customer-facing roles yourself to create efficiency and control.
- Doing so builds deep understanding and streamlines operations without outsourcing early on.
Spreadsheet System Foundation
- Adam and his cousin built complex spreadsheets connecting finance and customer acquisition that guided their entire business.
- That math-driven approach laid the foundation for what later became Pentane software.
Software Development Challenge
- Software development cycles are more fluid and ongoing than consumer product cycles which have physical production delays.
- Unlike fixed physical products, software goalposts move indefinitely requiring continuous development and adaptation.
