Founder insight

"Most early-stage founders are optimizing the wrong thing. They're building features when they should be finding customers."

Customer Acquisition · Founder to Founder™
Founder insight

"A system you actually use beats the perfect system you abandoned. Start simpler than you think you need to."

Systems & Operations · Founder to Founder™
Founder insight

"Revenue is feedback. Silence is data. A waitlist that converts is worth more than a thousand sign-ups that don't."
