Assumptions drive the valuation range

Most startup valuation disagreements are really assumption disagreements. The investor may not believe the growth rate, margin structure, market size, sales cycle, or exit potential.

Founders should track assumptions explicitly so the valuation can be updated when evidence changes.

Core assumptions to document

The right assumptions depend on the business model, but several categories appear in most early-stage valuations.

  • Monthly or annual growth rate.
  • Revenue quality and repeatability.
  • Gross margin and operating margin path.
  • Market size and reachable customer segment.
  • Churn, retention, or repeat usage.
  • Round size, runway, and dilution expectations.

Use sensitivity analysis before investor calls

Sensitivity analysis shows which assumptions matter most. If a small change in growth or margin moves the valuation materially, the founder should be ready to defend that assumption.

This turns valuation into a structured discussion instead of a negotiation based only on confidence.
