Are you a Startup founder preparing to pitch VCs or accelerators? Do you need a Pitch Deck that helps an Investor understand your story and traction? I help founders turn rough drafts, outdated slides, and Business Plan materials into a clear Pitch Deck built for real Investor conversations. With 9+ years of experience, I specialize in Pitch Deck development, Investor storytelling, PowerPoint execution, and Presentation Design for fundraising. I have completed 490+ Pitch Deck projects and supported founders whose companies raised $560M+ in tracked capital. My work is not only about making a Pitch Deck look polished. I shape the content, sharpen the message, improve the flow, and make every PowerPoint slide easier to understand. 🚀 My approach to content and design A strong Pitch Deck needs more than good PowerPoint visuals. It must answer Investor questions fast, explain why now, show traction clearly, and make the business case credible. I review your content through an Investor lens, identify gaps, simplify complex ideas, and reorganize the story before the Presentation Design stage begins. I help decide what belongs in the Pitch Deck, what should be removed, what needs stronger proof, and how each slide should support the next one. Once the story is clear, I translate it into clean PowerPoint slides with Presentation Design that supports clarity, trust, and momentum. 💼 What I help with • Full Pitch Deck creation from scratch • Pitch Deck redesign for an existing Investor deck • Pitch Deck content strategy and fundraising narrative • PowerPoint cleanup and PowerPoint formatting • Presentation Design for fundraising, board, and sales materials • Business Plan summary slides and Business Plan visuals • Startup story refinement and Investor messaging • Consumer Packaged Goods (CPG) and CPG Pitch Deck support for product, retail, ecommerce, and brand-led companies ✅ Why founders work with me • I build each Pitch Deck around real Investor logic • I turn complex ideas into simple PowerPoint slides • I use Presentation Design to improve clarity, not just aesthetics • I align your Pitch Deck with your Business Plan and Investor narrative • I deliver editable PowerPoint files that stay easy to update • I help each Startup communicate with more confidence 🧠 My process 1. Review your current Pitch Deck, notes, data, or Business Plan 2. Clarify your story, priorities, and core Investor questions 3. Improve the content flow, hierarchy, and fundraising logic 4. Rebuild the structure in PowerPoint with strong Presentation Design 5. Polish each Pitch Deck slide for readability and momentum 📊 Industries and stages I work with SaaS, AI, fintech, health tech, climate, marketplaces, Consumer Packaged Goods (CPG), and CPG Startup teams. Whether you need a new Pitch Deck, a sharper Pitch Deck, or a cleaner Pitch Deck, I focus on making each Investor interaction more effective through better content, PowerPoint storytelling, and Presentation Design. For Consumer Packaged Goods (CPG), I can explain product positioning, brand traction, retail strategy, ecommerce growth, unit economics, distribution, margins, and market opportunity in a way that feels clear to an Investor. A CPG Pitch Deck needs the right balance of story, numbers, visuals, product proof, and Business Plan logic, so Presentation Design must make the brand credible. 🎯 Services include • Fundraising Pitch Deck strategy • Fundraising Pitch Deck redesign • Pitch Deck content review and story improvement • PowerPoint template setup • PowerPoint master slides • Presentation Design systems • Presentation Design consistency checks • Presentation Design refinement • Business Plan to Pitch Deck transformation • Startup messaging support • Investor presentation updates • Financial slide cleanup in PowerPoint • Consumer Packaged Goods (CPG), CPG, and retail-focused Investor materials 💬 Client feedback often sounds like this “Sergio brought clarity, structure, and real Investor logic to our Pitch Deck.” “Excellent PowerPoint work, strong Presentation Design, and fast communication.” “He improved our content, refined the story, and made the Pitch Deck easier to present.” 📌 Final goal If your current Pitch Deck feels crowded, confusing, or outdated, I can turn it into a Pitch Deck that is clear, credible, and ready for the next Investor meeting. My goal is simple, build a Pitch Deck in PowerPoint with Presentation Design that supports your raise, reflects your traction, and helps every Investor understand the opportunity quickly. Need help with a Pitch Deck, PowerPoint, Presentation Design, Business Plan summary, Consumer Packaged Goods (CPG) fundraising material, CPG Investor deck, or Startup Investor presentation before your next Investor conversation? Send me a message and let’s build a stronger PowerPoint deck with Presentation Design.
