🚀 Gemini‑Powered Startup Pitch Builder

#kaggle

Introduction
You’ve poured your energy into brainstorming your next big startup—notes scattered across Notion, napkins, Google Docs. Yet when it’s time to pitch, you’re stuck wrestling with slide layouts, consistent styling and hunting down market data. Precious hours slip away. What if you could hand off that busywork to AI, so you can focus on refining your vision and talking to customers?

Why This Matters
Early‑stage founders, hackathon teams and corporate innovators all face the same crunch: you need a clear, compelling presentation fast. Manually crafting a deck can take days, and design isn’t everyone’s forte. Our notebook automates the entire process—so you spend less time on formatting and more time on the story that wins funding and attention.

Technology Stack
We combine industry‑leading tools into one seamless pipeline:
• Google Gemini for few‑shot prompting, embeddings and function calls
• LangChain to orchestrate prompts and retrieval logic
• FAISS as a vector store for instant similarity search over your own notes
• Notion API to fetch and clean raw idea pages
• python‑pptx to programmatically assemble a polished PowerPoint deck

The Core Workflow

Ingest and Embed
Fetch your Notion pages, split them into bite‑sized chunks, then embed each chunk with Gemini. FAISS indexes those vectors for blazing‑fast retrieval.

  splitter = RecursiveCharacterTextSplitter(chunk_size=512, chunk_overlap=50)
  documents = splitter.split_documents([Document(page_content=notes_text)])
  vectordb   = FAISS.from_documents(documents, embeddings)
  vectordb.save_local("notion_vectordb_gemini")
  retriever  = vectordb.as_retriever(search_kwargs={"k": 4})

Generate Structured Pitch
Teach Gemini your ideal slide format with a few real‑world examples, then ground its output in your own notes via Retrieval‑Augmented Generation. The result is clean JSON containing an elevator pitch, slide bullets and investor links.

  prompt = build_rag_prompt(notes_text, vibe="VC‑friendly")
  resp   = client.models.generate_content(
      model="gemini-2.5-pro-exp-03-25",
      contents=prompt,
      tools=[Tool(google_search=GoogleSearch())],
      generation_config=GenerateContentConfig(
          allow_tool_calls=True,
          response_mime_type="application/json"
      )
  )
  pitch = _safe_json(resp.text)

Export to PowerPoint
Use python‑pptx to turn that JSON into a styled slide deck—complete with title slide, custom backgrounds and formatted text boxes—in one automated step.

  prs   = Presentation()
  slide = prs.slides.add_slide(prs.slide_layouts[0])
  slide.shapes.title.text      = "🚀 Elevator Pitch"
  slide.placeholders[1].text   = pitch["elevator_pitch"]

  for text in pitch["deck"]:
      title, body = text.split(":", 1)
      sl = prs.slides.add_slide(prs.slide_layouts[5])
      sl.background.fill.solid()
      sl.background.fill.fore_color.rgb = RGBColor(242,242,242)
      # add title and body textboxes…
  prs.save("styled_pitch_deck.pptx")
Enter fullscreen mode Exit fullscreen mode

Investor Q&A Simulation
Stress‑test your story by asking Gemini to play investor and founder. You’ll get three probing question‑and‑answer pairs that surface narrative gaps before demo day.

  def simulate_qa(pitch_text):
      prompt = f"Act as an investor and ask 3 probing questions about:\n{pitch_text}"
      return client.models.generate_content(model=model_id, contents=prompt).text

  qa_pairs = simulate_qa(pitch["elevator_pitch"])
Enter fullscreen mode Exit fullscreen mode

Problems We Solve
• Time‑crunched deck creation—minutes, not days
• Design overwhelm—consistent, professional styling every slide
• Message drift—few‑shot templates lock in your structure and tone
• Credibility gaps—live web searches surface relevant investor links
• Narrative blind spots—simulated Q&A reveals weaknesses early

What You’ll Walk Away With
• A concise, tone‑matched elevator pitch
• A nine‑slide outline covering problem, solution, market, model, traction, team, financials and ask
• Curated investor links and benchmarks
• Three investor‑style Q&A pairs to sharpen your narrative
• A fully formatted PowerPoint deck, ready to share or customize

Who Benefits
• Founders racing to seed or pre‑seed deadlines
• Hackathon teams needing a demo‑day deck in hours
• Accelerators and incubators scaling pitch prep for cohorts
• Corporate innovators pitching new ideas internally

Pitch Builder frees you from slide‑making drudgery so you can return your energy to product, market and customer. Plug in your Notion workspace, pick your vibe—VC‑friendly, quirky, social impact—and watch your ideas become investor‑ready storytelling in under sixty seconds.
