Is Your Startup Idea Any Good? Borrow These Validation Tactics from the Founders of Linear, Mercury and More

First Round Review Free Intermediate

Most validation advice is generic. This one is specific, and it leans on founders (Linear, Mercury) who tested conviction and traction while still holding day jobs at Uber, Airbnb, and Coinbase, which is exactly your situation. Treat it as a menu of low-cost tests you can run on nights and weekends before you touch your resignation letter.

• Sell before you build: pitch the idea cold to strangers and watch for real buying signals (they ask about price, timelines, and want to loop in their team).
• Your current job is a research asset. Notice the painful, repeated problem you already see up close instead of chasing a novel one.
• Talk to strangers, not friends and colleagues, so the feedback is not softened by people who want to protect you.
