Episode notes
Build B2B Around Problems Customers Can't Solve
- Solve a hard part of the customer's problem that they can't or won't do themselves to build a defensible B2B business.
- Romero stresses talking to customers directly and validating pain points before scaling.
Find Opportunities By Listening Over Research
- Find market gaps by listening and buying drinks—people will tell you what annoys them.
- Romero used customer complaints as raw inputs to validate whether they'd pay to fix the problem.
Prefer Co-founders Over Going Solo Today
- Avoid solo founding when possible; Romero often started solo but says today he'd prefer co-founders.
- He notes early teams worked for low salary while he had taken the initial risk quitting his job.
