How to Explain Your Product in a Pitch Deck

Show one complete task

Consider a fictional visitor-registration tool for workplace teams. Its draft slide has five feature labels: pre-registration, visitor log, notifications, reporting and integrations. Those labels name capabilities, but leave the investor to connect the people and actions.

The revision follows one visit. A host creates the visit record. Reception marks the visitor as arrived. The product sends the host an arrival alert. The slide now shows who acts, what information moves and where the software takes over.

Give the sequence a direct headline: “From scheduled visit to host notification”. Keep the feature list for a later question about product breadth. In this first explanation, an integration matters only if the reader needs it to understand the task.

Follow one site through development

Illustrative energy-project example: replace “Origination, grid expertise, commercial structuring” with one proposed site moving from land rights to a signed offtake agreement. The sequence makes the developer’s contribution visible.

This is an explanation sequence, not a full development schedule. Workstreams can overlap; agreed connection terms do not mean the site is physically connected.

• Land controlThe landowner and developer agree site rights. The developer checks site constraints and shapes the project around the usable land.
• Grid connectionThe developer coordinates engineers’ studies and submissions; the grid operator assesses the connection. The developer brings the resulting requirements into the project design.
• Signed offtakeThe developer and electricity buyer sign a power purchase agreement. The developer aligns the delivery commitments with the project’s technical position and remaining conditions.

Explain the handoff, not every click

In Y Combinator’s pitching guidance, Michael Seibel recommends walking through the user path when a product is hard to describe. For your slide, choose a task that helps the investor understand the business, then show enough of the mechanism to make it believable.

In the example, the important handoff is the arrival alert. Simply drawing “Reception → Host” would leave the audience guessing whether someone phones, emails or uses the product. Labelling that arrow “Product sends alert” explains the software’s role.

If the product’s distinction is elsewhere, show that part instead. Choose the sequence around what the product does differently.

Use screens when they help explain the action

For a working product, a tightly cropped screen can show the action or result more directly than a schematic. Pair it with a short caption that tells the reader what to notice. Keep the relevant control, record or output readable; remove unrelated navigation from the teaching example, without misrepresenting the product.

For the visitor-registration example, an actual product walkthrough could show the created visit, the arrival action and the resulting alert. A collage of three full screens with tiny text would recreate the original problem: plenty to look at, little guidance on how the work connects.

Label the material accurately: a concept diagram explains an intended sequence; a prototype or production view shows a different stage. Use public-safe demonstration data. A smooth walkthrough shows how a task works; claims about saved time or better outcomes need their own evidence.

Match the explanation to the meeting

A short investor pitch needs a quick product explanation; a longer product meeting can include a deeper demonstration. Y Combinator’s Demo Day guidance stresses explaining the product clearly in that particular setting.

Before sending the deck, ask someone unfamiliar with the product to describe the task back to you. Listen for where they lose track of the actor, the product’s action or the result. That gap tells you what to clarify before adding another screen.
