Three specific discovery questions were present in 9 of 10 closed deals and absent in 8 of 10 lost deals. Advize is an AI-powered performance marketing agency that analyzed 20 B2B SaaS demo call transcripts in 2026, comparing 10 calls from deals that closed within 90 days against 10 calls from deals that were lost or stalled. This blog documents what those questions are and why their presence or absence predicts deal outcome.
Advize analyzed 20 B2B SaaS demo call transcripts in 2026. Three discovery questions were present in 9 of 10 closed deals and absent in 8 of 10 lost or stalled deals. The three questions: 'What would need to happen for this to become a priority in the next 60 days?' (urgency and trigger identification), 'Who else is involved in this decision and what is most important to each of them?' (stakeholder mapping), and 'What does success look like for you 6 months after you start using this?' (outcome definition that becomes the renewal metric).
What Is How the 20 B2B SaaS demo call analysis was structured and Why Does It Matter for Performance?
The 20 demo calls were selected from two B2B SaaS companies in the marketing technology and project management categories. Deals were classified as closed (contract signed within 90 days), lost (prospect chose a competitor), or stalled (no decision after 90 days). The 10 closed deals and 10 lost/stalled deals were transcribed and analyzed for the presence or absence of specific question types.
Three question types showed the highest correlation with deal outcome.

What are the 3 B2B SaaS discovery questions that predict deal closure?
Question 1 — Urgency and trigger identification: 'What would need to happen for this to become a priority in the next 60 days?' Present in 9 of 10 closed deals, 2 of 10 lost/stalled. This reveals whether there is a specific business trigger (a new hire, a deadline, a competitor move) that creates urgency for the evaluation. Deals with a named trigger close faster and at higher rates than exploratory evaluations.
Question 2 — Stakeholder mapping: 'Who else is involved in this decision and what is most important to each of them?' Present in 9 of 10 closed deals, 1 of 10 lost/stalled. This identifies the full buying committee before the vendor assumes the champion can close the deal alone. Deals that lose in procurement or at the executive level are almost always ones where the vendor mapped only the champion.
Question 3 — Success definition: 'What does success look like for you 6 months after you start using this?' Present in 9 of 10 closed deals, 2 of 10 lost/stalled. This forces the prospect to articulate a specific measurable outcome the product will be evaluated against, and creates the framework for the first customer success review after onboarding.

Conclusion
The three discovery questions identified across 20 demo call transcripts are simply specific questions that most sales teams avoid because they require the prospect to reveal something that might be awkward — urgency, budget, or decision process. The sales teams that ask them anyway close significantly more deals from the same demo quality because they identify genuine prospects from curious ones before investing additional time.
