Prove momentum with concrete metrics and timeframes so the audience can feel velocity.

What & why

What it is
In a spoken pitch, traction is the evidence that people want what you are building and that you can execute. Michael Seibel stresses the importance of velocity, not just absolute numbers. A metric without a timeframe is weak. A metric with a timeframe tells a story. For revenue companies, revenue growth and retention are usually the strongest signals. For pre-revenue companies, pilots, user growth, engagement, waitlist demand, or letters of intent can still work. The key is to choose evidence that shows momentum, not vanity.
Why it works

People judge momentum more than position, so a metric paired with a timeframe reads as a trajectory the listener can extrapolate forward, while a raw number sits flat and invites discounting. Concrete figures also act as social proof that real people already chose the product, which carries more weight than your own assertions. Specific numbers feel harder to fake than round vanity claims, raising credibility. Giving the audience a rate they can project lets them imagine the future themselves rather than being told to believe it.

Always pair the metric with the timeframe. In speech, that single detail is what makes traction feel real.

Questions & answers

What if I'm pre-revenue?

Show other forms of traction: user signups, waitlist size, pilot program results, letters of intent, advisor endorsements, or beta engagement metrics. The point is to demonstrate that real people want what you're building.

How many metrics should I show?

Lead with 2-3 of your strongest metrics. Too many numbers dilute the story. Pick the ones that best demonstrate velocity and product-market fit for your stage.
