Artificial intelligence is rewriting the rules for founders and startups. When my funding window slammed shut, I turned to ChatGPT and Gemini to craft a pitch deck from scratch—overnight. By morning, investors replied with, “Let’s talk.” That email changed my year.
ChatGPT and Gemini built my pitch deck – slide by slide, story by story
ChatGPT and Gemini, two top-tier chatbots in the artificial intelligence space, became my co-founders for the night. I started with a basic prompt:
“Act as a Y Combinator advisor. Build a pitch deck for a SaaS that helps small restaurants automate supply ordering. Include: problem, solution, market, business model, traction, and ask.”
ChatGPT structured each slide, wrote headlines that popped, and filled in key stats. Gemini fact-checked industry numbers, flagged investor jargon, and suggested UK market angles—crucial for my audience.
Their tag-team workflow let me skip hours of outline wrangling. My deck finally told a story—not just data points.
ChatGPT made my market size credible and concise
ChatGPT, using its vast language model and up-to-date web search, turned my messy research into investor-ready copy. I pasted a pile of links, then prompted:
“Summarize the UK and EU market size for restaurant SaaS solutions. Quote two real sources. Keep it under 60 words.”
ChatGPT replied:
“The UK market for restaurant automation software is valued at over £250M in 2025 (TechCrunch). Europe’s market is projected to exceed €800M by 2026 (Wired UK). Rising labor costs and pandemic recovery fuel adoption.”
Gemini then cross-checked these stats for accuracy, adding notes if my sources looked outdated or biased. That context boosted my confidence—and my credibility.
Claude humanized the narrative and made my “why now” resonate
Claude, Anthropic’s human-tone AI, didn’t just edit grammar—it found my hook. I pasted my rough intro and said:
“Rewrite this opening to sound urgent, relatable, and founder-driven. Use a single bold sentence to open.”
Claude delivered:
“Every night, restaurant owners lose hours to broken supply chains. I started this company after watching my family’s café nearly fold—because ordering lettuce took longer than making coffee.”
Suddenly, my deck was personal and urgent. Investors don’t just fund slides—they fund stories.
Gemini built my competitive analysis – and found my unique angle
Gemini, as an AI research assistant, mapped out my rivals and highlighted what made us different. I prompted:
“List three top competitors in UK restaurant supply tech. What do they do well, and what gap do we fill?”
Gemini created a table:
| Competitor | Strengths | Weakness / Our Edge |
| Orderly | Fast delivery, big | No AI menu planning, only chains |
| BistroLogic | Easy setup, good UX | UK only, no loyalty program |
| SmartStock | Cheap, scalable | Lacks supplier integration options |
This let me confidently say, “Here’s what nobody else is doing—and here’s why our AI is the difference.”
