DESIGNING PITCH DECKS IN THE AGE OF AI

There was a time when a pitch deck could get by on content alone. If the business made sense and the founder could carry the room, that was often enough to secure a second conversation. That world has changed.

Today, a founder can open an AI tool and generate a perfectly acceptable deck in minutes. The result may be clean and usable. For an early draft, that can be genuinely helpful. But is it ready to design the deck you put in front of investors?

Not quite.

The problem is that investor decks are not just presentation documents. They are judgement calls, made slide by slide. What belongs on the slide? What should be left unsaid? Where does the story need proof? When should the design get out of the way? That is where human design still matters. A good deck does not simply organise information. It guides attention and makes the business feel more investable.

Here are the principles we follow when building investor decks that do more than look polished.

1. Brand it with intent

A deck is often the first proper encounter an investor has with your company. Not just the idea, but the character behind it.

That does not mean plastering the logo everywhere or turning every slide into a brand showcase. In fact, over-branding can feel insecure. Good branding in a deck shows up in the confidence of the typography. It is there in the restraint of the colour palette. It appears in the way each slide feels unmistakably part of the same world.

AI can imitate a style. It can suggest a palette. What it cannot always understand is whether the design feels true to the business. A climate-tech deck should not feel like a crypto launch. A healthcare deck should not feel like a lifestyle app just because that style is fashionable. The visual language has to support trust in the business and make the company feel coherent.

 2. Use visuals because they earn their place

One of the quickest ways to spot a weak deck is through decorative visuals. Stock imagery used or icons dropped in because a slide looks empty. Diagrams that make a simple idea harder to understand. Strong decks use visuals with a job to do.

A product screenshot can make the use case click in seconds. A well-structured chart can turn traction into momentum. A customer quote, used sparingly, can bring the problem into the room in a way a paragraph never will. Ask, does the visual make the point faster or sharper? If it does, keep it. If it is only there to make the slide feel less bare, take it out.

This is where an experienced designer becomes very useful. Not because they make things prettier, but because they know when a slide needs presence and when it needs discipline.

3. Keep the slide focused

Founders often want to include everything. That is understandable. You have spent years building the business, so every detail feels important. Investors do not experience the deck that way. They are scanning for signal. They want to understand what matters and whether they believe it.

A strong slide usually has one job. Sometimes that job is to explain the market. Sometimes it is to prove demand. Sometimes it is simply to make the investor feel the scale of the opportunity. White space is not wasted space. It is what allows the important thing to land.  This is also where AI-generated decks often fall down. They tend to fill space because they can. A human designer knows that restraint is often what gives a slide authority.

4. Vary layouts to maintain engagement

Consistency matters, but repetition can really kill attention. A deck where every slide follows the same structure starts to feel flat, even when the content is strong. Investors may not consciously notice the repetition, but they may feel the energy drop.

For instance, a bold market insight might deserve a full-screen statement. A traction slide might need a clean chart with very little else competing for attention. A product slide may work best when the interface is allowed to take centre stage. Good variation should feel paced rather than random. It gives the story shifts in emphasis to keep people engaged and interested. This is something templates struggle with.

5. Design for the investor in front of you

A pitch deck should evolve as the business evolves. At pre-seed, the deck may need to work harder to sell the problem and the ambition. Later on, investors will expect more evidence. The design should shift accordingly, making traction easier to read and performance easier to trust.

Different investors also look for different things. A generalist may need more context around the category. A sector specialist may want you to get to the proof faster. The deck should be shaped around what they need to understand, what they are likely to question and what will help them believe.

A good designer will not just ask, does this look good? They will ask, who it’s for and what needs to land by the end.

6. Make design part of the thinking

The biggest mistake is treating design as the final polish (that along with giving it to designer the day of the pitch!).

By the time a deck reaches the ‘make it look good’ stage, many of the important decisions have already been made. Sometimes the story is too dense. Sometimes the order is wrong. Sometimes the strongest point is buried halfway down a slide. Design is not decoration at the end of the process. It should be part of how the argument is shaped.

A senior designer may challenge what belongs on the slide in the first place. They will see when a chart is trying to do too much, they might spot those repetitions that often creep in when people become over familiar with the copy. That is the part AI has not solved. It can produce options quickly, and those options can be useful. But it cannot sit with the nuance of a business, understand the room you are pitching to and make the all important judgement calls. A strong investor deck shows that you know your business. A well-designed one shows that you know how to communicate it.

We build decks that bring design and content together from the start. Not just to make a presentation look better, but  to make the story easier to understand and believe in.
