🎙️ Episode Context
This episode provides a tactical masterclass on founder-led sales, arguing that founders must personally drive early revenue to validate product-market fit before hiring sales teams.

She emphasizes vulnerability in discovery calls and the strategic use of services to wedge into accounts.
Problem It Solves
Spending time and money on sales automation tools before validating if the target persona or message actually resonates.
Framework Overview
Before scaling, founders must manually identify and message a small batch of high-quality leads. This creates a feedback loop to test discoverability (can I find them?) and resonance (do they care?) before automating bad processes.

When to Use
At the very beginning of the sales process or when pivoting to a new customer segment.
Common Mistakes
Buying expensive enrichment/automation tools (like Clay or Apollo) immediately and blasting 1,000 people with bad messaging.
Real World Example
A founder realizes they can't find 'High Net Worth Individuals' easily online, proving a discoverability flaw in their GTM strategy before writing a line of code.
Before you buy any tool... can you manually find 30 people that you want to spend 15 to 20 minutes writing a rock solid note to?
