5	Market Size	30s	TAM → SAM → SOM
6	Business Model	30s	How you make money
7	Traction	45s	Growth metrics, customers

9	Team	30s	Why you specifically will win
10	Financials	30s	Revenue projections, unit economics
11	The Ask	15s	How much, what for

Slide Design Rules

Typography

Element	Size (1920x1080)	Rule
Slide title	48-72px	Max 6 words
Key stat/number	96-144px	One per slide, when applicable
Body text	24-32px	Max 6 bullet points
Caption/source	16-20px	Cite data sources
Font	Sans-serif only	Inter, Helvetica, SF Pro, or similar

The 1-6-6 Rule

1 idea per slide
6 words max per bullet
6 bullets max per slide

If you need more text, you need more slides.

Color

Element	Guideline
Background	Dark (navy, charcoal) OR clean white — pick one, commit
Accent color	ONE brand color for emphasis
Text	White on dark, or dark grey (#333) on light
Charts	2-3 colors max, your brand color = "you"
Avoid	Gradients on text, neon colors, more than 3 colors

Layout

Rule	Why
Consistent margins (80-100px)	Professional, clean
Left-align text (never center body text)	Easier to scan
One visual per slide	Focus attention
Slide numbers	Helps investors reference specific slides
Logo in corner	Subtle brand reinforcement

Slide-by-Slide Visual Guide

1. Title Slide

belt app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1920px;height:1080px;background:#0f0f23;display:flex;align-items:center;justify-content:center;font-family:system-ui;color:white;text-align:center\"><div><h1 style=\"font-size:80px;font-weight:900;margin:0\">DataFlow</h1><p style=\"font-size:32px;opacity:0.7;margin-top:16px\">Automated reporting for data teams</p><p style=\"font-size:22px;opacity:0.5;margin-top:40px\">Seed Round — Q1 2025</p></div></div>"
}'

2. Problem Slide

One big number + one sentence.

belt app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1920px;height:1080px;background:#0f0f23;display:flex;align-items:center;padding:100px;font-family:system-ui;color:white\"><div><p style=\"font-size:24px;color:#f59e0b;text-transform:uppercase;letter-spacing:3px;margin:0\">The Problem</p><h1 style=\"font-size:144px;margin:20px 0;font-weight:900;color:#f59e0b\">12 hrs/week</h1><p style=\"font-size:36px;opacity:0.8;line-height:1.4\">The average data analyst spends 12 hours per week<br>building reports manually</p><p style=\"font-size:20px;opacity:0.4;margin-top:30px\">Source: Forrester Research, 2024</p></div></div>"
}'

5. Market Size (TAM/SAM/SOM)

Use concentric circles, not pie charts:

belt app run infsh/python-executor --input '{
  "code": "import matplotlib.pyplot as plt\nimport matplotlib\nmatplotlib.use(\"Agg\")\n\nfig, ax = plt.subplots(figsize=(19.2, 10.8))\nfig.patch.set_facecolor(\"#0f0f23\")\nax.set_facecolor(\"#0f0f23\")\n\ncircles = [\n    (0, 0, 4.0, \"#1e1e4a\", \"TAM\\n$50B\", 40),\n    (0, 0, 2.8, \"#2a2a5a\", \"SAM\\n$8B\", 32),\n    (0, 0, 1.4, \"#818cf8\", \"SOM\\n$800M\", 28)\n]\n\nfor x, y, r, color, label, fontsize in circles:\n    circle = plt.Circle((x, y), r, color=color, ec=\"#333366\", linewidth=2)\n    ax.add_patch(circle)\n    ax.text(x, y, label, ha=\"center\", va=\"center\", fontsize=fontsize, color=\"white\", fontweight=\"bold\")\n\nax.set_xlim(-5, 5)\nax.set_ylim(-5, 5)\nax.set_aspect(\"equal\")\nax.axis(\"off\")\nax.text(0, 4.8, \"Market Opportunity\", ha=\"center\", fontsize=36, color=\"white\", fontweight=\"bold\")\nplt.tight_layout()\nplt.savefig(\"market-size.png\", dpi=100, facecolor=\"#0f0f23\")\nprint(\"Saved\")"
}'

7. Traction Slide

Show growth, not just numbers. Up-and-to-the-right chart.

belt app run infsh/python-executor --input '{
  "code": "import matplotlib.pyplot as plt\nimport matplotlib\nmatplotlib.use(\"Agg\")\n\nfig, ax = plt.subplots(figsize=(19.2, 10.8))\nfig.patch.set_facecolor(\"#0f0f23\")\nax.set_facecolor(\"#0f0f23\")\n\nmonths = [\"Jan\", \"Feb\", \"Mar\", \"Apr\", \"May\", \"Jun\", \"Jul\", \"Aug\"]\nrevenue = [8, 12, 18, 28, 42, 58, 82, 120]\n\nax.fill_between(range(len(months)), revenue, alpha=0.3, color=\"#818cf8\")\nax.plot(range(len(months)), revenue, color=\"#818cf8\", linewidth=4, marker=\"o\", markersize=10)\nax.set_xticks(range(len(months)))\nax.set_xticklabels(months, color=\"white\", fontsize=18)\nax.tick_params(colors=\"white\", labelsize=16)\nax.set_ylabel(\"MRR ($K)\", color=\"white\", fontsize=20)\nax.spines[\"top\"].set_visible(False)\nax.spines[\"right\"].set_visible(False)\nax.spines[\"bottom\"].set_color(\"#333\")\nax.spines[\"left\"].set_color(\"#333\")\nax.set_title(\"Monthly Recurring Revenue\", color=\"white\", fontsize=32, fontweight=\"bold\", pad=20)\nax.text(7, 120, \"$120K MRR\", color=\"#22c55e\", fontsize=28, fontweight=\"bold\", ha=\"center\", va=\"bottom\")\nax.text(7, 112, \"15x growth in 8 months\", color=\"#22c55e\", fontsize=18, ha=\"center\")\nplt.tight_layout()\nplt.savefig(\"traction.png\", dpi=100, facecolor=\"#0f0f23\")\nprint(\"Saved\")"
}'

8. Competition Slide

Never use a feature matrix against competitors. Use a 2x2 positioning map.

# See the competitor-teardown skill for positioning map generation
belt app run infsh/python-executor --input '{
  "code": "import matplotlib.pyplot as plt\nimport matplotlib\nmatplotlib.use(\"Agg\")\n\nfig, ax = plt.subplots(figsize=(19.2, 10.8))\nfig.patch.set_facecolor(\"#0f0f23\")\nax.set_facecolor(\"#0f0f23\")\n\ncompetitors = {\n    \"Us\": (0.6, 0.7, \"#22c55e\", 300),\n    \"Legacy Tool\": (-0.5, 0.5, \"#6366f1\", 200),\n    \"Startup X\": (0.3, -0.4, \"#6366f1\", 200),\n    \"Manual Process\": (-0.6, -0.6, \"#475569\", 150)\n}\n\nfor name, (x, y, color, size) in competitors.items():\n    ax.scatter(x, y, s=size*5, c=color, zorder=5, alpha=0.8)\n    weight = \"bold\" if name == \"Us\" else \"normal\"\n    ax.annotate(name, (x, y), textcoords=\"offset points\", xytext=(15, 15), fontsize=22, color=\"white\", fontweight=weight)\n\nax.axhline(y=0, color=\"#333\", linewidth=1)\nax.axvline(x=0, color=\"#333\", linewidth=1)\nax.set_xlim(-1, 1)\nax.set_ylim(-1, 1)\nax.set_xlabel(\"Manual ← → Automated\", fontsize=22, color=\"white\", labelpad=15)\nax.set_ylabel(\"Basic ← → Advanced\", fontsize=22, color=\"white\", labelpad=15)\nax.set_title(\"Competitive Landscape\", fontsize=32, color=\"white\", fontweight=\"bold\", pad=20)\nax.tick_params(colors=\"#0f0f23\")\nfor spine in ax.spines.values():\n    spine.set_visible(False)\nplt.tight_layout()\nplt.savefig(\"competition.png\", dpi=100, facecolor=\"#0f0f23\")\nprint(\"Saved\")"
}'

9. Team Slide

# Generate professional team headshots/avatars
belt app run falai/flux-dev-lora --input '{
  "prompt": "professional headshot portrait, person in business casual attire, clean neutral background, warm studio lighting, confident friendly expression, corporate photography style",
  "width": 512,
  "height": 512
}'

Layout: Photos in a row with name, title, and one credential each.

Person	Format
CEO	Name, title, "Ex-[Company], [credential]"
CTO	Name, title, "Built [thing] at [Company]"
Others	Name, title, one relevant credential

Max 4 people on the team slide. More = unfocused.

Chart Guidelines

Chart Type	Use For	Never Use For
Line chart	Growth over time (traction)	Comparisons between categories
Bar chart	Comparing amounts	Time series (use line)
Concentric circles	TAM/SAM/SOM	Anything else
2x2 matrix	Competitive positioning	Feature comparison
Single big number	Key metric highlight	Multiple metrics
Pie chart	NEVER	Anything (hard to read, unprofessional)

Chart Design Rules

Rule	Why
Max 2 colors per chart	Clarity
Your company = green or brand color	Positive association
Label directly on chart	No separate legend needed
Remove gridlines or make very subtle	Reduce clutter
Start Y-axis at 0	Don't mislead
Cite data sources	Credibility

What Investors Look For

Slide	Investor's Real Question
Problem	"Is this a real problem people pay to solve?"
Solution	"Is this 10x better than the status quo?"
Market	"Is this big enough to matter?"
Traction	"Is this actually working?"
Team	"Can these people execute?"
Ask	"Is this a reasonable deal?"

Common Mistakes

Mistake	Problem	Fix
Too many slides (20+)	Loses attention, unfocused	Max 12-15 slides
Wall of text	Nobody reads it	1-6-6 rule: 1 idea, 6 words, 6 bullets
Feature comparison table vs competitors	Looks defensive	Use 2x2 positioning map
Pie charts	Hard to read, unprofessional	Use bar charts or big numbers
No data sources cited	Looks made up	Always cite sources
Team slide with 8+ people	Unfocused	Max 4, focus on relevant experience
Inconsistent design	Looks amateur	Same colors, fonts, margins on every slide
No "The Ask" slide	Investor doesn't know what you want	State amount, use of funds, timeline
Vanity metrics	"1M visits" means nothing without conversion	Show revenue, active users, retention
Too much product demo	This is a business pitch, not a demo	Max 2 slides on product, focus on business
