How to show traction and financials in a pitch deck

Fewer charts, each with a point

I design these slides for a living, and what goes wrong with them is rarely the data. It’s the slide trying to say six things at once. The fixes are boring, and they work:

• One chart per message, and one message per chart.
• A headline that states the takeaway, not the name of the metric.
• The metrics that fit your stage, defined once and used the same way everywhere.
• Actuals and forecast that look different, with the assumptions on the slide.
• The detail in the appendix, where the people who want it will look.

Traction

Traction is evidence that the company is working: revenue, users, retention, pilots, whatever proves the thing people doubted. On a slide it’s usually the one chart that answers “is this real?”

Financials

Financials are what the company has earned and spent, and what it expects to earn and spend next. In a pitch deck that’s the summary, not the model. The model lives in the data room.

Definitions come first

Before any of it gets designed, pin down what each metric means: what counts as revenue, as an active user, as a customer. A beautiful chart of a fuzzy metric is still fuzzy, and the first question in the meeting will be about the definition, not the chart. The numbers and their definitions are yours, or your finance lead’s. My job is making them readable, not changing them.

It changes with the round

These are the charts I see most often at each stage, from the decks I design. They’re a starting point, not a rulebook. What a given investor wants to see varies, so ask them.

Seed: early signal

At seed you’re selling the team, the insight and a bit of early signal. Chart the one metric that proves the most, whatever you actually have: revenue, users, a waitlist, pilots. Pilots and design partners can be shown without names if they’re under NDA, and a before-and-after from a pilot often says more than a growth line. If there isn’t much to chart yet, show fewer, clearer things. A thin chart made to look busy fools nobody.

Series A: evidence

By Series A you’re selling evidence. Expect revenue growth over time, a retention or cohort view, customer count or expansion, a view of the pipeline or go-to-market, and early signs that the unit economics work. The design job is making a dense set of data readable without shrinking the type until nobody can read it.

Series B: repeatable, efficient growth

By Series B the question is whether the growth repeats and whether it pays for itself. That usually means revenue growth split into its drivers (new customers, expansion, churn), net revenue retention and cohort retention, unit economics such as CAC payback, LTV to CAC and gross margin, efficiency over time, and a forecast tied to explicit assumptions. Several dense charts that still read fast, and an appendix for everything behind them.

There are no benchmark figures on this page, on purpose. What counts as good depends on the business model, the market and the year, and a benchmark without a source does more harm than none.

Past results and forecast are different things

Put them on the same chart if it helps, but make the switch visible: a divider, a lighter or dashed fill, a label that says where actual stops and forecast starts. A forecast styled exactly like the actuals reads as a fact, and the investor who notices will wonder what else was styled to look better than it is.

Label the assumptions

The two or three assumptions the forecast rests on go on the slide, or right next to it. The full model goes in the appendix or the data room. If the forecast only works under an assumption you’d rather not show, that’s worth knowing before the meeting.

Units, periods and currency

State them once, in the same place on every slide: monthly or annual, thousands or millions, which currency. Round the same way throughout, and footnote how each metric is defined.

Use of funds and the ask

One clear slide: what the round pays for and what it’s meant to get the company to, in words you’d say out loud. The free pitch deck template has a slide for the ask you can use as a structure.

Market sizing

One number, the reasoning behind it, and a source. The usual failure is three concentric circles with big numbers and no method. If you can’t say where a market figure came from, cut it, because someone in the meeting will ask.

Start from what you’re showing

Pick the chart from what you’re trying to show, not from whatever the spreadsheet offers first.

When a table is better

Sometimes a table is the honest choice: a few exact figures people will want to read precisely, a cap table, a forecast broken into line items. Design the table properly instead of forcing a chart.

What to leave out

• 3D effects.
• Two axes on one chart.
• Decorative gridlines, shadows and gradients.
• Pie charts with more than a few slices.

Headline the takeaway

The headline says what the chart shows, like “Revenue grew every quarter”, never what it is, like “Revenue”. The real sentence has to come from your data, but the rule doesn’t change: if the headline is just the name of the metric, the reader has to work out the point alone, and they might not work out yours.

One highlighted point

One chart, one message, one highlighted point. Everything else goes grey. If a slide needs two messages, it’s two slides.

My test

Show the slide to someone for a few seconds, take it away, and ask what it said. If they can say the point out loud, the slide works. If they describe the chart instead, it isn’t there yet.

Make it readable on any screen

• Label lines directly instead of using a legend, wherever there’s room.
• Label the axes and the units. Start bar charts at zero.
• Keep the same scale, colours and order on every slide that shows the same metric.
• Set the type big enough for a laptop and a phone. Most decks get read on a screen long before anyone presents them.
• Don’t rely on colour alone. Check the contrast, and write alt text for any chart you share as an image.

What goes wrong, and the fix

• A chart with no takeaway headline. The reader has to find the point. Write it for them.
• Too many metrics on one slide. Nothing stands out. Pick the one that proves the most and move the rest to the appendix.
• A forecast styled like the actuals. It reads as a promise. Change the style where actual stops.
• A truncated axis that exaggerates growth. Someone will notice, and then doubt every chart after it. Start bars at zero.
• A vanity metric shown big, the real one in a footnote. Investors read footnotes. Lead with the metric that matters.
• Definitions that change between slides. The numbers stop adding up. Define each metric once and hold it.
• A screenshot of a spreadsheet. Nobody can read it on a phone. Rebuild it as a chart or a clean table.
• One colour, several meanings. Red is churn here and the highlight there. Give each colour one job, deck-wide.
• A market-size figure with no source. It gets discounted to nothing. Cite it or cut it.

When to get help with the data slides

The split is simple. Your finance lead owns the numbers and what they mean, and a presentation designer makes them readable. If the narrative is solid and it’s the charts that let it down, that’s a Deck. If the argument still has to be built, that’s a Story. The tiers are on the pricing page, and how I work on the data slides is on the pitch deck design page.

I design data slides for decks at any stage: seed, Series A, Series B and later rounds. Still deciding whether you need anyone? Do you need a pitch deck designer? is the honest version. If you’re building the charts yourself, pick the tool first, the one the people updating the numbers already use.

How many charts should a pitch deck have?

A pitch deck has as many charts as it has points that need proving with data, and no more. There is no fixed count: each chart earns its slide by making one point the deck needs. If two charts make the same point, keep the clearer one.

What is the best chart to show traction in a pitch deck?

The best traction chart is usually a line or column chart of the one metric that shows growth, under a headline that states the takeaway. The metric decides the chart: revenue over time suits a line or columns, and retention suits a cohort view. One highlighted point does more than a legend.

Should a pitch deck show financial projections?

A pitch deck usually shows a forecast at some level, kept clearly apart from actual results, with the assumptions behind it stated. How much detail it needs depends on the stage and on the investor, so it is worth asking. The full model belongs in the appendix or the data room.

What traction metrics does a Series B pitch deck show?

A Series B pitch deck commonly shows growth alongside retention, unit economics and efficiency: revenue split into new, expansion and churn, net revenue retention, cohort retention, CAC payback, LTV to CAC, gross margin, and a forecast tied to its assumptions. Which of these lead depends on the business model, so a usage-based company and a seat-based one will open with different metrics. Whatever is shown, each metric is defined once and used the same way on every slide.

How do you show a forecast without it looking like a promise?

A forecast reads as a plan rather than a promise when it looks different from the actuals, sits next to its assumptions and shows its drivers. A divider, a dashed or lighter fill and a label mark where actual results stop. The two or three assumptions it rests on go on the slide, and the full model goes in the appendix.
