5 Nano Banana prompts every startup should try

With a great startup idea, you need great visuals to sell it.

From pitch decks to product pages, startups constantly need images that look professional and credible. The problem is that design work and product photography can be expensive, especially for early-stage founders.

That is where Nano Banana comes in.

Nano Banana refers to Google’s Gemini 2.5 Flash Image model, a fast AI image generation tool that became widely popular in 2025. It allows users to create photorealistic images using simple text prompts. According to the tech giant, more than 200 million images have already been edited using the tool globally.

For bootstrapped startups, this can replace studio shoots, graphic designers, and even early prototypes. Here are 5 powerful Nano Banana prompts that every startup can try!

From idea to visual: 5 Nano Banana prompts startups should try

1. Brand identity kit prompt

One of the first challenges for a startup is building a consistent visual identity. Hiring a designer for logos, colour systems, and icons can cost thousands of rupees. Nano Banana can generate a full brand concept within seconds.

Example prompt:

Create a complete brand identity kit for a modern tech startup named “[Startup Name]”. Include logo variations, a cohesive colour palette (Primary: #HEX, Secondary: #HEX), typography system, and a custom icon set. Style should be clean, futuristic, and minimal. Generate mockups of the logo on a business card, a laptop decal, and a glass office sign.

Here is a sample response of Gemini's Nano Banana for your reference:

Why it works:

• Explore branding directions quickly

• Visualise identity before hiring designers

• Keep branding consistent across assets

2. One-shot performance infographic

Startups frequently need to explain complex data to investors, partners, and customers. Instead of designing slides manually, founders can turn raw numbers into shareable visuals.

Example prompt:

Generate a clean, modern 3-panel infographic summarising these highlights: [paste your data].

Panel 1: Bold title with category label

Panel 2: 5 numbered steps explaining the process

Panel 3: Key results section with large metric blocks and green trend arrows

Use a corporate style with rounded corners and high contrast text for mobile readability.

Why it works:

• Simplifies investor communication

• Creates shareable LinkedIn visuals

3. Virtual product studio prompt

Product photography can easily cost Rs 20,000 to Rs 1,00,000 for a small catalogue shoot. Nano Banana allows founders to generate studio-quality product visuals instantly. This is particularly useful for D2C brands and e-commerce startups.

Example prompt:

Top-down photography of my product [describe product] arranged in a knolling grid on a textured dark wood surface. Surround it with accessories such as [list 3 items]. Lighting: soft studio softbox with even illumination and sharp focus on all items. Ensure the product logo is visible.

Note: Knolling refers to arranging objects neatly at right angles so every item is clearly visible.

Why it works:

• Create and test product photos without a photoshoot

• Generate images for e-commerce listings

4. Realistic lifestyle scene prompt

Lifestyle images help products look relatable. Instead of showing only a product, these visuals show people using it in real situations. For SaaS startups or hardware products, lifestyle images make marketing pages look far more credible.

Example prompt:

Subject: A young professional using a premium laptop in a bright, open office.

Environment: Large windows with a blurred city skyline during golden hour.

Lighting: Soft Rembrandt-style lighting with a warm glow.

Details: Realistic reflections, subtle shadows, brushed aluminium texture on the laptop.

Note: Rembrandt lighting refers to a portrait lighting technique that creates depth and contrast.

Why it works:

• Creates realistic website visuals

• Improves brand storytelling

• Replaces expensive photoshoots

5. Comparative UI mockup prompt

Before writing code, startups often need to visualise different interface designs. Nano Banana can generate multiple product UI concepts instantly.

Example prompt:

Create a side-by-side comparison of three UI mockups for an analytics dashboard.

Option 1: Minimalist data-dense interface for power users

Option 2: Visual card-based interface with charts and graphs

Option 3: Experimental dark mode layout with modern typography

Use a consistent brand colour palette and realistic placeholder text.

Why it works:

• Visualise product ideas early

• Test multiple design directions

• Communicate UI concepts clearly

The takeaway

Early-stage startups move fast, and budgets are limited. Tools like Nano Banana allow founders to create professional visuals instantly without designers or studio photography. From brand identity kits to product mockups and UI concepts, the right prompts can unlock powerful marketing assets. Sometimes the difference between a rough idea and a compelling startup story is simply the image that tells it.
