Smiling 10 Seconds More in Your Pitch Video Raises Your Funding Odds by 15%
This is not a self-help claim. This is the finding of a peer-reviewed study published in the Journal of Finance.
Quick Answer
Smiling for 10 additional seconds within a 60-second startup pitch video is associated with a 15% rise in the probability of being funded, according to a peer-reviewed study by Allen Hu and Song Ma published in the Journal of Finance, which analyzed over 1,100 accelerator pitch videos using machine learning. Teams that sounded more enthusiastic were 27% more likely to be funded, and teams that looked more positive were 17% more likely to be funded; a one-standard-deviation improvement in overall "Pitch Factor" translated to a 35% increase in funding probability. The uncomfortable twist: conditional on getting funded, high-Pitch-Factor startups subsequently underperformed on employment growth, follow-on funding, and survival compared to less charismatic peers, meaning investors were moved by delivery in ways that didn't correlate with actual company quality. The deck and business fundamentals still matter, but the research shows a founder's positivity, warmth, and vocal enthusiasm during the pitch itself carry outsized weight in whether investors say yes.

Does smiling really increase funding odds?
Researchers Allen Hu and Song Ma analysed over 1,100 accelerator pitch videos using machine learning, then tracked which teams actually received investment.
They quantified the emotional signals in each pitch — positivity, enthusiasm, warmth, vocal energy — and modelled them against funding outcomes.
The results were striking.
Funding lift for teams that looked more positive
Funding lift for teams that sounded more enthusiastic
Funding lift from one SD improvement in "Pitch Factor"
How much does smiling affect funding probability?
Dr Hu put a number on it that is almost uncomfortably precise:
Increase in funding probability from smiling 10 additional seconds in a 60-second pitch video
Do better pitchers build better companies?
Now the uncomfortable second finding.
Conditional on getting funded, high-Pitch-Factor startups subsequently underperformed on employment growth, follow-on funding, and survival.
Investors were being moved by delivery in ways that did not correlate with company quality.
Founders with better pitches were winning capital that founders with better businesses were not.
The implication: If you are raising and you are not training your delivery with the same rigour you apply to your financial model, you are competing asymmetrically against founders who are.
What does this mean for founders raising capital?
The deck matters. The business matters.
But the research says the person presenting them matters more than almost anyone in the room will admit.
What investors respond to (research-backed):
- •Positivity and genuine warmth
- •Vocal enthusiasm and energy
- •Confident but calm demeanour
- •Natural, authentic emotional expression
