Showing traction to investors without a pitch deck

Many first-time founders spend weeks on a pitch deck: the fonts, the market-size slide, the animated logo. Then they learn how decks are read. DocSend, which tracks how investors open the decks founders send, reported in 2025 that "investors spend less than 3 minutes reviewing pitch decks these days."

Three minutes. That's not a reason to skip a deck forever, but it is a reason to stop treating the deck as the thing that convinces. Paul Graham's "How to Convince Investors" starts with an analogy: people hurt their backs lifting with their back instead of their legs, and founders make the same mistake by trying to convince with their pitch. "Most would be better off if they let their startup do the work."

Here's how to let your startup do the work.

What investors are actually looking for

Graham boils it down to three things: "formidable founders, a promising market, and (usually) some evidence of success so far." The deck can describe the market. Only you can show the other two, and the best way to show both is a record of progress.

That's what traction is. It's not a single impressive number. It's evidence that you keep making things happen.

What counts as traction at your stage

Traction looks different depending on where you are:

• Idea: a sharp written description of the problem, and twenty conversations with people who have it.
• Building: a working prototype, a waitlist, a few people trying it weekly.
• Launched: active users, and how many come back.
• Revenue: paying customers, monthly revenue, how fast it's growing.
• Selling to businesses: pilots, letters of intent, signed contracts.

Graham gives a benchmark in "Startup = Growth": "A good growth rate during YC is 5-7% a week." He also says what to measure: revenue is best, and "the next best, for startups that aren't charging initially, is active users."

Step 1: Pick one number and track it weekly

Choose the number that best shows people getting value: weekly active users, revenue or completed orders. Track it every week, on the same day, in a simple spreadsheet. Don't change the definition when the week is bad.

A chart of one honest number, rising, is more convincing than ten slides of projections.

Step 2: Make a one-page proof

YC's seed guide recommends a short executive summary, "one or two pages (one is better)," covering vision, product, team, traction, market size and minimum financials. Make that page now, before anyone asks for it:

• One sentence on what it does and who it's for
• The chart of your one number
• Three short quotes from real users, with permission
• What you shipped in the last month
• What's next, and what you need to get there

This page goes in emails, gets forwarded to partners, and is what you send after a coffee.

Step 3: Show the product, live

The fastest way past a skeptical investor is a sixty-second demo on your phone. It shows the product exists, that it works, and that you know it inside out. Practise it until you can do it without thinking, including what to do when the wifi drops.

Step 4: Keep a public trail of what you ship

A changelog, release notes or a short weekly "shipped" post builds a visible record over time. It answers the question investors are really asking early on: does this person get things done?

Graham's essay makes the point about early growth: "At three months, a growth graph is mostly evidence that the founders are effective." The same is true of a steady changelog. Each entry is small. Together, they show momentum.

Step 5: Collect customer evidence

Numbers are stronger with names behind them:

• Pilots with a start date and a success measure
• Letters of intent from businesses
• Retention: of the people who tried it in March, how many still use it?
• Quotes that describe the problem in the customer's words

Step 6: Send short updates to investors you've met

Once a month, send the investors you've talked to a few lines: your number, what you shipped, one problem you're working on. No attachments, no ask.

This is where traction pays off. Graham notes that "investors who reject you are some of your warmest leads for future fundraising." An investor who has watched your number rise for four months, in your own monthly updates, doesn't need a deck to believe you.

Step 7: Still have a deck, just don't lead with it

To be fair to decks: YC's guide still says you'll probably want an executive summary and a slide deck that works as "a coherent leave-behind," so partners who weren't in the meeting can follow your story. Build one when investors start asking for it. Just build it from the proof you already have, with the traction slide doing most of the work. DocSend's numbers fit this too: investors "spent over four minutes looking at pitch decks that successfully raised money," and the business model section is where they spent the most time.

Also say no to anyone who asks for heavy diligence too early. YC's guide is direct about it: "Do not spend too much time developing diligence documents for a seed round."

Where The Build Nation fits

The Build Nation is a free, real-time network for builders, investors, mentors and businesses, live in San Francisco. It's built on the same idea as this post: visibility should come from what you've done, not how loudly you post.

Your profile keeps a running record of your work: builds you've marked as launched, "Shipped:" updates you post on the community board, meetups you hosted, and an 18-week proof-of-work grid. Your public profile has its own link you can send to anyone, and it shows work only, never your location or your connections. In Meet, recent results like launches and "Shipped:" updates can lift you among the people you're a good match for. Likes and followers never count. How ranking works explains exactly what's included.

To be clear about the limits: what you post is self-reported, and The Build Nation doesn't verify your revenue or user numbers. It's not a substitute for real metrics or a data room. It's a place where your progress is visible to the builders and investors around you, and a reason to meet in person.

The short version

Decks get skimmed. Progress gets remembered. Pick one number, track it weekly, make a one-page proof, ship visibly and send short updates. When an investor finally asks for a deck, most of the convincing has already been done.
