What a pitch deck traction slide has to do
A traction slide answers one question: is this working? Not "is the market big" or "is the team good". Those have their own slides. Traction is evidence that customers want the thing and that the rate they want it is going up.
Rate is the key word. Paul Graham's essay on growth puts it plainly: a good growth rate during YC is 5 to 7% a week, and 10% a week is exceptional. He also names the metric to measure it on: revenue first, and active users if you aren't charging yet. That's a useful default for picking the hero number on your slide.
So the job of the design is to make the rate visible. A reader should be able to tell, without reading the axis, whether things are speeding up.
Pick one question before you pick a chart
The best breakdown I've read of real traction slides is Deck.gallery's study of seven funded decks. Its conclusion is that each good slide answers a single question and refuses to dilute it. Linear's slide is the number 5,000+ over a wall of customer logos, with no revenue line at all, because the question it answers is "who uses this?". Lunchbox shows three numbers (18% adoption at launch, 31% at three months, 49% at six) because its question is "how fast does it spread?".
I'd add one thing from the design side. The question decides the chart type, so settle it first. When a traction slide has six charts on it, it's usually because nobody decided which question mattered most.
- "Is revenue growing faster?" Monthly revenue as bars, one bar per month
- "Who trusts us?" One headline number and recognisable logos, only if the names land on first read
- "Does usage stick?" A small cohort table or three labelled data points, as Lunchbox did
- "Is there demand before launch?" A waitlist or pilot count, paired with a quality signal so it doesn't read as hype
Stop using cumulative charts on your traction slide
This is the first habit I'd drop. A founder plots total customers or total revenue since launch, and the line climbs beautifully.
The trouble is that it always climbs. The a16z guide to startup metrics makes the point directly: cumulative charts always go up and to the right for any business with any activity, and they can do it even while the business is shrinking. Investors know this. Haje Jan Kamps at TechCrunch went further and wrote a whole column telling founders to banish cumulative graphs, because investors want to see accelerating growth and that's much harder to read on a cumulative line.
The fix is simple. Plot each period on its own: new MRR per month, revenue per month, active users per week. If the bars are getting taller, the reader sees acceleration in a second. If one month dipped, show it and add a one-line note explaining why. A dip with a reason is believable. A line that never wobbles makes people dig.
Keep projections off the traction chart
Dotted lines extending into next year are the second habit to go. Ash Rust argues that most investors will assume a projected figure is your current number, which sets up disappointment later. And the bigger projected bars make your real bars look small by comparison, so the slide undersells what you've actually done.
I'd follow his suggestion: real traction as a bar chart on the traction slide, and projections as a table in the appendix or on the financials slide. If the money you're raising is meant to bend the curve, show that link on your use of funds slide rather than on the traction chart.
Traction slide design rules that survive a phone screen
Your deck will probably be read on a phone, forwarded without you there to explain it. These are the rules I apply to every traction chart before it ships.
- Write the takeaway as the slide title. "Revenue up 4x in 12 months" beats "Traction", and the reader gets the point even if the chart doesn't render well
- Label the bars directly. Put the value on the first bar, the last bar and any inflection, and drop the gridlines and the legend
- Start the y-axis at zero. A truncated axis makes small growth look steep, and anyone who notices will discount everything else on the slide
- Use one highlight colour. Grey for history, your brand colour for the latest period or the inflection you want them to see
- Date everything. Put the month range under the chart so "$40k MRR" has a when attached
- Cap the supporting numbers. Deckary's guide suggests four to six metrics at most; I'd rather see one chart and two or three small numbers beside it
How to show traction before you have revenue
Early decks still need this slide; the evidence just looks different. Graham's fallback of active users applies here, and so do signals like pilots, letters of intent or a waitlist.
The design trap at this stage is the vanity number. A waitlist alone overstates intent, which is why Deck.gallery points out that Diagram paired its 16,000+ designer waitlist with a separate adoption slide once the product was in use. If you only have a waitlist, add whatever shows quality: how many converted to a pilot, how many came back in week two, or how many said yes to a paid plan. My seed pitch deck guide covers where this slide sits in an early-stage story.
And if your strongest proof is a handful of customers rather than a chart, that's fine. Use a short list of named customers with one line on what each one does with the product. Just don't dress three logos up as a logo wall.
A quick check before you send the deck
Show the traction slide to someone outside the company for five seconds, then take it away. Ask them two things: is the business growing, and is it growing faster than before? If they can't answer both, the chart is doing too little or too much.
Most of the fixes are small: switch cumulative to per-period, delete the projection, rewrite the title as a sentence. If the problem is bigger than the chart, the pitch deck design rules I use on client work are a good next step, and if you'd rather hand it over, here's how I work and what it costs.
