## TL;DR
From rubber duck debugging to AI sounding boards to strategic sparring partners — why solo founders need to know which one they're reaching for.

## What is rubber duck debugging and why do founders do it?
Rubber duck debugging is a problem-solving technique where you explain your problem out loud to an inanimate object, forcing yourself to articulate the issue clearly. Solo founders naturally adopt this habit — journaling, voice memos, talking through decisions alone — because articulating a problem is often the first step to solving it.

## Can AI replace a rubber duck for problem solving?
AI is an upgraded rubber duck — it listens, responds, and can help iterate on ideas at any hour. But AI reflects your framing back to you. It answers the question you asked, not the question you should have asked. It cannot challenge assumptions it doesn't know are assumptions, which is the critical gap that strategic human advisors fill.

## What is the difference between a sounding board and a sparring partner?
A sounding board reflects your ideas back to you with validation or light feedback. A sparring partner actively challenges your framing, asks questions you didn't think to ask, and draws on pattern recognition from experience across many businesses. The difference is between confirming your thinking and improving it.

## Do solo founders need a rubber duck, a mastermind, or a strategist?
Solo founders benefit from all three at different moments. Use rubber ducking or journaling when you need to clarify your own thinking. Use AI when you need to explore options, research, or iterate on drafts. Use peer masterminds for accountability and shared experience. Use a strategist when you need someone who can tell you you're solving the wrong problem.
