Claude Design can produce a complete startup pitch deck with wireframes, a financial model, and speaker notes in a single session. The key is using the Idea Browser to inject structured product context before opening Claude Design, which produces dramatically better wireframes than starting from a blank prompt. Greg Isenberg demonstrated the full workflow live with real LTV/CAC numbers: $228 LTV, $62 CAC, a 3.7x ratio built inside Claude Design in one session.

What is the difference between Claude Design and Claude Code for building product mockups?

Claude Code generates functional code that runs in a browser. Claude Design generates visual design assets: wireframes, hi-fi mockups, design systems, and presentation slides. Neither replaces the other. For a pitch deck, the deliverable is a visual presentation, not a working app, so Claude Design is the right tool.

The practical difference when building pitch decks is that Claude Design asks structured product management questions before it starts generating. It forces clarity on audience, core value proposition, and user flow before rendering anything visual. Teams that have tried to build pitch decks directly in Claude Code spend time explaining visual layout to a code-focused system. Claude Design is built for the visual output.

What is the Idea Browser and why use it before opening Claude Design?

Idea Browser is an MCP tool that injects business context directly into Claude sessions. It stores information about the target customer profile, growth strategy, positioning, and competitive landscape, then surfaces that context automatically when Claude needs it.

The workflow is to define the product concept in Claude chat first using Idea Browser, then switch to Claude Design with that context already loaded. The difference in output quality is significant. Without context, Claude Design produces generic SaaS wireframes. With Idea Browser context, the wireframes reflect the actual user journey, the correct vocabulary for the target audience, and the right information hierarchy for the business model.

How do you build a financial model inside a pitch deck session?

The approach that produced the $228 LTV, $62 CAC output was to give Claude Design the following inputs in sequence:

Revenue model: Subscription, transactional, or hybrid. Monthly price point and expected churn rate.
Acquisition channels: Paid social, SEO, direct sales, or referral. Cost estimates per channel.
Cohort assumptions: Average months to recover CAC and expected LTV at 12 and 24 months.

Claude builds the model from these inputs and renders it as slides with the key ratios highlighted. The LTV/CAC ratio is the metric most investors look at first. A 3x ratio is the commonly cited threshold for a healthy unit economics story. Claude will surface this ratio prominently without needing to be told which metrics matter.

Claude Design also generates speaker notes for each slide. These notes are written to be spoken, not read, which is the format most founders struggle to write in under time pressure.

What are the quota limits in Claude Design and how do you work around them?

Claude Design has a generation quota that resets on a rolling basis. The quota burns faster with complex multi-element renders than with simple wireframes. Running simultaneous projects inside a single session causes the first project to cancel when the second is initiated. Work on one deck at a time.

The practical workflow for managing quota is:

Brainstorm the concept fully in Claude chat before opening Claude Design. Quota only burns once you are generating visuals.
Prefer low-fi wireframes for initial iterations. Low-fi wireframes use fewer tokens per frame than hi-fi renders and are faster to review for structural feedback.
Use Sonnet 4.6 for iterative changes. Save Opus 4.7 for final renders where quality is the priority.
Export to ZIP when quota runs out. The ZIP contains the design files in a format Claude Code can continue working with. Re-import to Claude Design when the quota resets.

What does a complete pitch deck session look like from start to finish?

A complete session follows this sequence:

Stage 1 (Claude chat, 15 to 20 minutes): Define the product concept using Idea Browser. Answer the structured questions about the customer, the problem, and the solution. Establish the financial model inputs. This stage costs no Design quota.

Stage 2 (Claude Design, wireframes): Generate low-fi wireframes for the core slides: problem, solution, market size, product demo, business model, team, ask. Review each wireframe for structural accuracy. Request revisions one change at a time to preserve rendering quality.

Stage 3 (Claude Design, design system): Generate a design system from the brand concept defined in Stage 1. Apply it across all slides in one shot rather than applying it incrementally.

Stage 4 (Claude Design, hi-fi and financials): Upgrade the wireframes to hi-fi renders with the design system applied. Generate the financial model slides with the unit economics inputs. Add speaker notes to complete the deck.

What is the business case for selling this as a service?

Design agencies charge $5,000 to $20,000 for a pitch deck. A productized Claude Design sprint can deliver wireframes, a financial model, and speaker notes in one 3 to 4 hour session. The rate for a single session service is $500 to $2,000 depending on complexity and the founder's budget.

The market is early-stage founders who need a deck for their first fundraise or a customer meeting within a week, not a design agency timeline. The positioning is speed and cost, not craft for craft's sake. Most seed decks do not need to be design artifacts; they need to communicate the unit economics clearly and tell a coherent story.

Frequently asked questions

Does Claude Design require a separate subscription from Claude?

Claude Design is part of the Claude Max plan. It is not available on the free tier. Check the current plan tiers at claude.ai for the latest pricing, as Anthropic updates access levels regularly.

Can Claude Design export to PowerPoint or Google Slides?

Claude Design exports to ZIP containing design files. Conversion to PowerPoint or Google Slides requires a manual import step. For investor presentations, exporting as a PDF from the design file is typically sufficient and avoids formatting issues that occur during slide software imports.

How accurate is Claude's market research for pitch decks?

Claude generates market size estimates based on training data. For a pitch deck used with real investors, verify the TAM/SAM/SOM numbers against a primary source: Statista, IBISWorld, or a relevant industry report. Use Claude's numbers as a starting framework to stress-test, not as citations.

What is the best prompt structure for requesting a new slide?

One change per prompt delivers better results than multi-part instructions. For example: “Create a problem slide. The problem is that founders spend 40 hours building pitch decks that go stale after two investor meetings.” Do not add “and also make it match the design system” in the same prompt. Make the structural request first, then request the styling in a follow-up.

Is Idea Browser available as a standalone tool or only as an MCP?

Idea Browser operates as an MCP connector that installs into Claude Desktop. It is not a standalone web app. The MCP populates Claude's context with structured business information that persists across the session rather than needing to be re-stated in every prompt.
