Discovery Call Prep

Get a research brief, smart questions, and a clear game plan before every sales call.

SaaS Business Metrics Calculator

• Calculates customer lifetime value (LTV) and acquisition cost (CAC) to see if your model is sustainable
• Measures cash runway and burn rate so you know how long you can operate before needing more funding
• Computes Rule of 40 and other efficiency ratios to balance growth against profitability
• Analyzes payback periods and gross margins to determine if you're ready to scale marketing spend
• Compares acquisition channels to find which ones recover costs fastest

Discovery Call Prep

• Researches the prospect company — size, stage, recent news, and what someone in their role likely cares about
• Writes a call hypothesis: their probable pain, why they'd care about you, and what might kill the deal
• Builds a question flow that moves from context to pain to buying process without feeling like an interrogation
• Defines what success looks like so you know if the call actually moved things forward
• Suggests a specific next step to propose at the end of the call
