Hey, welcome to Product Market Fit!

This is the newsletter read by top founders and early-stage investors who want to ship faster, grow smarter, and raise with confidence.

Every week, we break down what’s actually working in the startup trenches—tools, tactics, and playbooks founders are using right now to reach product-market fit and scale beyond it.

Today’s issue is about one of the most underused founder skills of 2025:
Prompting.

If you're still using AI tools like a glorified chatbot, you're missing the entire point.

This guide will show you how to turn ChatGPT (or any AI) into your co-founder—complete with field-tested prompt structures, reusable templates, and advanced techniques to 100x your output across product, growth, ops, and fundraising.

🧠 In this issue of Product Market Fit:

  1. The 5-part structure every high-performing prompt should follow

  2. Reusable prompt skeletons for any LLM (ChatGPT, Claude, Gemini…)

  3. Field-tested prompt templates for:

  • ✅ Product prioritization (RICE scoring)

  • 📈 Cold email & GTM copy

  • 💸 Investor outreach + fundraising one-liners

  • 🧑‍💻 Hiring job descriptions

  • 🧾 Internal ops (updates, task handoffs, onboarding)

  1. Advanced prompting techniques:

  • Chain-of-thought reasoning

  • Self-critique loops

  • Few-shot prompting

  • Dynamic variable scaling for outreach
