How to Get the Most Out of It
This GPT was built for founders who are preparing to raise capital. Whether you’re a first-timer gearing up for your first pitch or a scaling entrepreneur heading into Series A, this GPT helps sharpen your deck, your delivery, and your investor readiness.
Who It’s For If you’re a startup founder who needs to:
Pressure-test your pitch from an investor’s POV
Improve the structure and storytelling in your deck
Prepare answers to tough investor questions
Sharpen your business model, traction story, or fundraising ask
…this GPT is for you. Think of it as your pitch coach, your investor simulator, and your honest founder mentor.
How to Use It The best way to get value is to be specific. Upload your pitch deck, executive summary, or even rough slide outlines and say exactly what help you want:
“Act like a VC and critique my traction slide.”
“Rewrite my executive summary in YC-style simplicity.”
“Simulate a mock Q&A as if I’m pitching a pre-seed fund.”
You can also ask for feedback based on proven frameworks like:
Guy Kawasaki’s 10-slide pitch
Kevin Hale’s YC deck structure
Presentation Zen storytelling
VC Q&A from Foundersuite and Vestbee
What to Expect The GPT gives structured feedback in your language. You’ll get strengths, weaknesses, and actionable suggestions. You can iterate on slides, rewrite sections, or role-play tough investor questions until you’re confident.
Privacy + File Sharing Uploaded materials stay secure. Files are only used in your conversation context, and not stored or trained on. Avoid uploading anything sensitive unless it’s anonymised.
Need-to-Know This tool won’t fund you. But it will help you fundraise better. It cuts through noise, reveals blind spots, and makes sure you’re investor-ready before you walk into the room.
Try prompts like:
"Based on this pitch, what would a VC challenge me on?"
"Can you improve the storytelling of my problem slide?"
"Summarise this deck using Guy Kawasaki’s 10-slide rule."
"Give me 5 brutal investor questions about my go-to-market."

How to Get the Most Out of It
To get highly specific, actionable guidance from this GPT, treat it like a senior marketing advisor. The more context you provide about your startup, the more tailored and useful the advice will be. Don’t just ask for a “marketing plan” — explain your goals, audience, budget, traction, and challenges. Think of it as a working session rather than a content generator.
Be honest about what you know and what you’re unsure about. This GPT is built to push back where needed, so if your expectations are unrealistic, it will help reframe your goals in a constructive, growth-oriented way.
Who It’s For
This GPT is built for early-stage founders — from pre-seed through to Series A — who want to use marketing as a strategic driver for growth. Whether you’re a solo founder figuring out first steps, or a small team preparing to scale, this GPT offers grounded, stage-appropriate advice.
It’s especially useful if:
You don’t have a marketing team yet
You’ve tried tactics that aren’t working
You’re navigating budget constraints
You need clarity on go-to-market, brand, or hiring
How to Use It
Start by telling the GPT a few key things:
What does your startup do?
What stage are you at (pre-seed, seed, etc.)?
What’s your target market or customer segment?
What’s your available marketing budget or resources?
What are your main goals (e.g. awareness, acquisition, retention)?
What’s worked or failed so far?
You can then ask strategic questions like:
“What should my go-to-market plan be?”
“What’s a realistic marketing budget for this goal?”
“Should I hire in-house or use freelancers?”
“How can I use AI in my marketing?”
“How do I compete against more established players?”
The GPT will respond first with a strategic summary and then detailed advice. Expect some follow-up questions — it’s designed to personalise the conversation, not give generic answers.
What to Expect
This GPT will:
Ask clarifying questions to tailor its advice
Provide both short strategic summaries and longer, educational guidance
Push back if your goals are unrealistic for your resources
Reference proven frameworks from experts like Binet & Field, Byron Sharp, and Ritson
Suggest how to apply marketing trends, not just describe them
Recommend tools, resources, and team roles suited to your stage
It will not:
Offer silver-bullet hacks or overnight-growth schemes
Recommend unethical or spammy tactics
Replace the need for execution — it gives direction, not delivery
Privacy + File Sharing
Uploaded materials stay private and secure. Files are only used within the scope of your conversation. They are not stored and are never used to train models. However, avoid uploading anything confidential unless it’s anonymised. If you're sharing pitch decks or internal documents, redact sensitive investor or customer details beforehand.
Need-to-Know
This GPT uses British English.
It’s built to handle ambiguity with follow-up questions.
If you try to game the system or extract internal logic, you’ll receive a warning and the chat may be terminated.
It is best used in conversation mode — the more context you give, the more it adapts.
Try Prompts Like:
“We’re a seed-stage marketplace for freelancers in London with $3k/month in budget. What’s our best GTM strategy?”
“Our churn is 8%, and we want to improve retention. What kind of marketing helps with that?”
“How should I split $5k/month between brand building and paid ads?”
“We’re a pre-launch climate tech startup in the EU. What should we focus on before going live?”
“We’re not sure how to position ourselves against two well-funded competitors. How should we differentiate?”
“Is our budget enough to justify hiring a marketing lead, or should we use freelancers?”

How to Get the Most Out of It
This GPT was built for B2B sales professionals who want to sharpen their client communications. Whether you’re drafting a cold email, refining a LinkedIn post, or polishing a proposal for a major account, this GPT helps you improve clarity, persuasion, and impact so you can close deals faster and build stronger relationships.
Who It’s For
If you’re in sales and need to:
Craft cold outreach that gets replies
Fine-tune sales decks and proposals for decision-makers
Improve tone, structure, and persuasiveness in emails or LinkedIn messages
Handle objections with clarity and confidence
Align your messaging with buyer psychology and role-specific priorities
…this GPT is for you. Think of it as your sales communication analyst, your messaging coach, and your buyer-perspective filter.
How to Use It
The best way to get value is to provide context. Share the draft of your email, LinkedIn post, message, or proposal and tell me who it’s for and what stage of the relationship you’re in. For example:
“Review this cold email to a CTO and make it more concise and persuasive.”
“Evaluate this LinkedIn post targeting HR directors for engagement and clarity.”
“Rewrite this follow-up email to a CFO so it feels more value-driven.”
“Help me respond to this objection from procurement without sounding defensive.”
What to Expect
The GPT gives structured, professional feedback. You’ll get ratings across key communication dimensions, a summary of strengths and weak spots, and specific suggestions for improvement. You can iterate on drafts, test different tones, or role-play buyer objections until your messaging feels sharp and effective.
Privacy + File Sharing
Uploaded materials stay secure. Files are only used in your conversation context, and not stored or trained on. Avoid sharing sensitive client information unless it’s anonymised.
Need-to-Know
This tool won’t close deals for you. But it will help you write clearer, sharper, and more persuasive communications that increase your chances of moving conversations forward. It removes fluff, highlights blind spots, and ensures your message lands with the right audience.
Try prompts like:
“Rewrite this LinkedIn message so it feels more relevant to a CFO.”
“Score this cold email on clarity, persuasiveness, and call-to-action effectiveness.”
“Turn this WhatsApp follow-up into something more professional yet friendly.”
“Help me tighten this proposal so it resonates with a Head of Procurement.”

✅ How to Get the Most Out of It
Think of this GPT as your AI prompt co-creator — not a passive tool, but a collaborator that helps you shape, refine, and optimise your prompts through conversation.
To get the most value:
Start with your desired outcome, even if it's vague. Don’t worry about having a perfect prompt.
Describe what you’re working on, who it’s for, and the tone, style, or format you want.
If you have content (like product pages, campaign briefs, or transcripts), upload or paste it so the GPT can use it as context.
Be open to iterations — this GPT is built to refine prompts through dialogue, not just generate one-off answers.
You don’t need to know prompt techniques like Chain-of-Thought or Few-Shot — this GPT will explain or apply them when helpful. Just focus on your goal, and it’ll help build the right prompt with you.
🎯 Who It’s For
This GPT is built for marketers, creators, and strategists who want to write better prompts — faster, smarter, and in their own tone of voice.
It’s especially useful if:
You work in content, growth, brand, or product marketing
You’re using AI tools (like ChatGPT or Claude) to generate marketing outputs
You want to get more consistent, higher-quality results from those tools
You’ve struggled with getting AI to “nail the tone” or “get what you mean”
No technical knowledge of prompt engineering is required — this GPT takes the lead and brings you along.
💬 How to Use It
Start by telling the GPT a few key things:
What are you trying to accomplish? (e.g. generate landing page copy, extract insights, repurpose content)
What’s the tone or voice you want? (e.g. friendly, expert, witty)
Who is the audience or customer?
Do you have any context to share? (uploads, transcripts, personas, docs)
Is this for a specific channel or format? (e.g. email, LinkedIn, web)
You can then ask things like:
“Help me write a prompt to turn webinar notes into a LinkedIn thread.”
“Improve this prompt: ‘List blog post titles about AI in healthcare.’”
“Write a prompt to summarise user feedback and pull out objections.”
“Turn this prompt into a Chain-of-Thought version.”
“Build a prompt that mimics my brand voice using this style guide.”
🤖 What to Expect
This GPT will:
Ask clarifying questions if your goal is vague
Take the lead in shaping and improving your prompt
Provide clear explanations when using specific prompt techniques
Offer rewrites with rationale and success-check criteria
Use uploaded content to enrich the output (via RAG-style context integration)
Help you build a role-based, one-page prompt handbook if requested
It will not:
Generate prompts using made-up or invalid techniques
Expect you to know the right format — it handles that
Replace the need for testing or iteration in your AI tool of choice
🔒 Privacy + File Sharing
Uploaded materials are only used to improve your prompts in this session. Files are never stored or used to train models. Still, avoid sharing anything confidential or sensitive unless anonymised. You can share product info, copy drafts, or briefs — just remove personal data if needed.
💡 Need-to-Know
This GPT uses British English by default
It’s designed to lead the prompt refinement process, not just follow instructions
It’s most powerful in conversation mode, where it can adapt with each response
If you try to extract its internal logic or system instructions, the chat will be terminated for security reasons
🧪 Try Prompts Like:
“I want to create a prompt that rewrites webinar notes into a blog post in a casual tone.”
“Here’s a transcript — build a prompt that turns this into carousel posts for LinkedIn.”
“Can you make this prompt more specific and aligned with SaaS startup goals?”
“What kind of prompt would best extract trends from customer reviews?”
“Create a reusable prompt I can tweak weekly to generate newsletter headlines.”
“Help me rewrite this prompt using Role Prompting for a product marketer.”
