TL;DR: Track filler frequency per minute, replace fillers with deliberate pauses, and slow your pace into the 140-160 WPM range. Most founders improve quickly with short daily recording loops.
Here's something investors won't tell you directly: filler words in a pitch don't just sound sloppy. They signal that you haven't prepared. When a founder says "um" twelve times in a three-minute pitch, the investor isn't thinking about the filler words themselves. They're thinking, "If this person didn't prepare for the most important meeting of their company's life, how will they prepare for everything else?"
We know this because we built Pitchr — an AI pitch coach for founders — and filler word count is one of the delivery metrics we track. After watching hundreds of recorded pitches, we can say this with confidence: how to reduce filler words in a pitch is one of the highest-leverage things a founder can work on, and almost nobody teaches it properly.
Every "pitch tips" article online says "reduce your ums." None of them explain the mechanics of why filler words happen, how to identify your personal patterns, or what to do instead. This post does.
Why Filler Words Matter More Than You Think
Toastmasters International — the organization that's been teaching public speaking since 1924 — assigns a specific role at many meetings: the "Ah-Counter." One person's entire job is to tally every filler word every speaker uses. They do this because filler frequency is one of the strongest predictors of perceived speaker competence.
Investor meetings work the same way, just without a formal counter. VCs sit through five to ten pitches per week. They develop an ear for delivery quality the same way a sommelier develops a palate. They can't always articulate why one founder seemed more credible than another, but filler word frequency is often the invisible variable.
Consider two founders making the same claim:
Founder A: "So, um, our market is, like, basically about $4 billion, and, you know, we think we can capture, like, maybe 2% of that."
Founder B: "Our target market is $4 billion. We're going after 2% in the first three years. Here's why that's realistic."
Same information. Completely different conviction signal. Founder A used six filler words and two hedge words in one sentence. Founder B used zero. An investor hearing Founder A unconsciously downgrades their confidence in every claim that follows — not because of the filler words per se, but because of what they imply.
The Three Types of Filler Words (and Which Ones Are Most Dangerous)
Not all filler words are created equal. We categorize them into three groups, and the most damaging one is the type most founders don't even realize they're using.
Verbal Fillers
These are the classics: "um," "uh," "ah," "er." They happen in the gaps between thoughts, usually when your mouth is moving faster than your brain can supply the next word. They're the most noticeable and the easiest to fix because they're purely mechanical — you can replace them with silence.
Phrase-Level Fillers
"You know," "I mean," "basically," "actually," "so," "like," "right?" These are harder to catch because they feel like real words. A founder might say "So basically what we do is..." without realizing that "so basically" adds zero information. These tend to cluster — founders who use "basically" often also use "actually" and "you know" in the same pitch.
Hedge Words (The Most Dangerous)
"Sort of," "kind of," "maybe," "I think," "we're hoping to," "we believe we might." These aren't just filler — they actively undercut your claims. When a founder says "We're kind of like Uber for pet care," the investor hears uncertainty. When they say "We think our churn is around 5%," the investor wonders if they actually know their numbers.
Hedge words are the most dangerous type of filler in an investor pitch because they do double damage: they eat up your limited time and they weaken the specific claims you need investors to trust. We cover hedge words in depth in our guide on first-time founder pitch mistakes.
The Record-Count-Replace Method
Telling someone to "stop saying um" is about as useful as telling someone to "just relax." You need a method. Here's the one that works, based on what we've seen from founders who measurably improved their pitch speaking pace and filler frequency.
Step 1: Record a Full Pitch
Set a timer for three minutes. Deliver your pitch to your phone camera. Don't stop if you mess up — push through. The goal isn't a clean take. The goal is an honest sample of how you actually speak under mild pressure.
Step 2: Count Your Fillers Per Minute
Play back the recording. Tally every verbal filler, phrase-level filler, and hedge word. Divide by three (minutes). That's your filler rate.
Here's the benchmark we use:
| Filler Rate | Assessment | |---|---| | 0–2 per minute | Investor-ready. Your delivery sounds deliberate and prepared. | | 3–5 per minute | Noticeable. Investors will register it subconsciously. Fixable in a few practice sessions. | | 6–10 per minute | Distracting. Your content is being overshadowed by delivery noise. Needs focused work. | | 10+ per minute | Critical. This will be the primary thing investors remember about your pitch, and not in a good way. |
Step 3: Replace Fillers With Pauses
This is the actual technique. Every filler word is a placeholder for silence. Your brain inserts "um" because it's uncomfortable with a gap. The fix is to practice tolerating the gap.
Here's the drill: record your pitch again, but this time, every time you feel a filler word coming, stop talking. Just stop. Let the silence sit for a full second. It will feel excruciating at first. After five practice runs, it will feel natural. After ten, you'll actually prefer the pauses — they give your claims room to breathe.
The counterintuitive thing about pauses is that they make you sound more confident, not less. A founder who pauses before a key number ("We grew revenue... 340% last quarter") sounds like someone who knows the number matters. A founder who fills the same gap with "um" sounds like someone who's scrambling.
How Speaking Pace Connects to Filler Frequency
You can't fix filler words without also talking about pace. They're linked. Founders who speak above 170 words per minute use significantly more fillers than founders who stay in the 140–160 WPM range. The reason is simple: when your mouth outpaces your thoughts, your brain fills the gap with noise.
The optimal pitch speaking pace is 140–160 WPM. For reference:
- Normal conversation: 170–190 WPM
- TED Talks (average): 150–160 WPM
- Nervous founders (first 30 seconds): often 190–210 WPM
- Ideal investor pitch: 140–160 WPM
That's slower than you think. It feels almost artificially slow when you first try it. But from the investor's side, it sounds prepared. It sounds like you've practiced. It sounds like you're choosing your words, not scrambling for them.
How to Practice This Before Your Next Meeting
If your meeting is in a week, here's a daily schedule that fits into fifteen minutes:
Day 1–2: Record once per day. Don't fix anything — just count. Get your baseline filler rate and pace.
Day 3–4: Record twice per day. Second take: focus on replacing fillers with pauses.
Day 5–6: Record twice per day. Second take: aim for 150 WPM. Slowing down automatically reduces fillers.
Day 7: Record a final "performance" take. Compare to Day 1. Most founders see a 40–60% reduction in filler frequency.
If you want to skip the manual counting, Pitchr does it automatically. Upload each recording and you'll see your filler count, filler rate per minute, average WPM, and pause distribution — with session-over-session trends so you can track improvement.
The One Change That Fixes Half the Problem
If you take only one thing from this post, take this: replace every single filler — every "um," every "basically," every "sort of" — with one full second of silence.
You'll feel awkward. You'll think the silence is too long. It isn't. One second of silence feels like five seconds to the speaker and half a second to the listener. And in that half-second, the investor is processing your last claim — which is exactly what you want them to do.
Filler words steal that processing time. Pauses give it back.
If your next investor meeting matters, spend fifteen minutes today recording your pitch, counting your fillers, and practicing the pause. It's the smallest change with the biggest impact on how investors perceive your preparation, your conviction, and your readiness to run a company. And once your delivery is clean, make sure the content itself is solid — avoid these 5 content mistakes that kill investor pitches.
FAQ
How many filler words per minute is too many in an investor pitch?
More than 3–4 per minute is noticeable to investors and signals under-preparation. Aim for fewer than 2 per minute. The most effective founders use deliberate pauses instead of filler sounds.
What is the ideal speaking pace for an investor pitch?
140–160 words per minute. That's slower than normal conversation (170–190 WPM) but fast enough to maintain energy and hold attention. Going below 120 WPM sounds over-rehearsed; above 180 WPM sounds anxious.
How do I stop saying 'um' when pitching investors?
Practice replacing every filler with a deliberate one-second pause. Record yourself delivering your pitch. Count the fillers. Then re-record, forcing yourself to pause instead of filling gaps with sound. Most founders see a 40–60% reduction in filler frequency within a week of daily practice.
Are hedge words worse than 'um' in a pitch?
Yes. "Um" is delivery noise — it's distracting but doesn't weaken your actual claims. Hedge words like "sort of," "kind of," and "maybe" actively undercut the content of what you're saying. Telling an investor "we sort of have product-market fit" is worse than telling them "um, we have product-market fit." Fix hedge words first.
