Every term investors use when they talk about pitch decks — defined plainly, without jargon.
What is a pitch deck?
A pitch deck is a short presentation — typically 10 to 15 slides — that founders use to communicate their business to potential investors. Its job is not to close a deal. Its job is to earn the next conversation.
A pitch deck covers the problem being solved, the solution, the market opportunity, the business model, traction to date, the team, and the funding ask. The best pitch decks do this in under 12 slides with enough clarity that an investor can explain the business to a colleague after reading it cold.
What is a pre-seed pitch deck?
A pre-seed pitch deck is a pitch deck used to raise the earliest institutional round of funding — typically between $250,000 and $2M — before significant product traction or revenue exists.
At pre-seed, investors are betting on the founder and the thesis, not the metrics. A pre-seed pitch deck focuses on the problem, the timing, the team’s unique insight, and early market validation rather than revenue or growth figures.
What is a seed pitch deck?
A seed pitch deck is used to raise a seed round — typically $1M to $4M — when the product exists and early traction is beginning to show. Seed decks are expected to include real traction data: revenue, growth rate, customer count, or retention metrics.
The narrative shifts from “here is our thesis” to “here is early proof that our thesis is correct.”
What is investor-market fit?
Investor-market fit describes the alignment between a startup’s stage, sector, and business model and a specific investor’s thesis, fund size, and portfolio focus.
Sending a pre-seed B2B SaaS deck to a late-stage consumer fund is not a deck problem — it’s an investor-market fit problem. Most pitch deck rejections that feel personal are actually investor-market fit mismatches.
What is a traction slide?
The traction slide is the slide in a pitch deck that presents evidence of momentum — typically revenue, growth rate, customer count, retention, or other metrics that demonstrate the business is working.
At pre-seed, traction slides can include pre-revenue evidence: customer discovery interviews, letters of intent, waitlist signups, or paid pilots. At seed and beyond, investors expect hard metrics.
What is a problem slide?
The problem slide is the slide that explains the pain point your business solves. It is typically the most important slide in a pitch deck — because if investors don’t feel the problem, nothing that follows will matter.
A strong problem slide contains one specific, quantified, undeniable truth about your target market. It describes a situation that is immediately recognizable to anyone in that market.
What is Duygu’s Law of Problem Clarity?
Duygu’s Law of Problem Clarity states: if your problem slide needs more than one sentence to explain the problem, it is not a problem slide yet.
The law exists because most founders confuse a situation with a problem. A situation is something that exists. A problem is something that hurts. The problem slide should communicate pain — specifically, quantifiably, and in a single sentence that is undeniably true to any potential customer in your market.
What is a TAM/SAM/SOM slide?
TAM/SAM/SOM is a market sizing framework commonly used in pitch decks.
- TAM (Total Addressable Market): The total global revenue opportunity if you captured 100% of the market.
- SAM (Serviceable Addressable Market): The portion of TAM you can realistically reach with your current product and distribution.
- SOM (Serviceable Obtainable Market): The portion of SAM you can realistically capture in the near term.
Investors are most interested in SAM and SOM — because TAM is often theoretical. The most credible market sizing is built bottom-up: number of realistic customers × average revenue per customer per year.
What is a bottom-up market size?
A bottom-up market size is calculated from actual customer data rather than from industry reports.
Formula: number of potential customers × average price per customer per year = addressable market.
Example: 8,000 mid-market manufacturing companies × $45,000 average annual contract = $360M addressable market.
Bottom-up market sizing is more credible to investors than top-down TAM calculations because it’s anchored in real customer behavior rather than theoretical market percentages.
What is founder-market fit?
Founder-market fit describes the specific alignment between a founder’s background, experience, and insight and the market they’re building in.
Investors look for founder-market fit because it explains why this specific person will outcompete others who could theoretically build the same thing. Strong founder-market fit often looks like: the founder previously had the exact problem they’re solving, or spent years inside the industry they’re disrupting, or has unique access to customers or distribution that others don’t.
What is a SAFE?
A SAFE (Simple Agreement for Future Equity) is a financial instrument commonly used in pre-seed and seed fundraising. It gives investors the right to receive equity in a future priced round in exchange for capital today.
SAFEs typically have a valuation cap (the maximum valuation at which the SAFE converts to equity) and sometimes a discount rate (a reduced price per share at conversion as a reward for early risk). They were created by Y Combinator and are now the standard instrument for early-stage US startup fundraising.
What is a valuation cap?
A valuation cap is the maximum company valuation at which a SAFE or convertible note converts into equity.
Example: an investor puts in $100,000 on a SAFE with a $5M cap. When the company raises a priced round at a $10M valuation, the SAFE converts as if the valuation were $5M — giving the investor more shares than they would have received at the $10M price. The cap protects early investors from being diluted by rapid valuation increases.
What is a convertible note?
A convertible note is a debt instrument used in early-stage fundraising that converts into equity at a future funding round. Unlike a SAFE, a convertible note accrues interest and has a maturity date by which it must either convert or be repaid.
SAFEs have largely replaced convertible notes at pre-seed in the US, but convertible notes are still common in international markets and at slightly later stages.
What is dilution?
Dilution is the reduction in an existing shareholder’s ownership percentage that occurs when new shares are issued — typically in a funding round.
Example: a founder owns 100% of a company. After a seed round where investors receive 20% equity, the founder owns 80%. Their ownership has been diluted by 20 percentage points.
Dilution is normal and expected in venture-backed startups. The goal is for each round of dilution to be offset by an increase in the company’s total value — so that a smaller percentage of a more valuable company is worth more than a larger percentage of a less valuable one.
What is runway?
Runway is the amount of time a startup can operate before running out of cash, given its current burn rate.
Formula: cash in bank ÷ monthly burn rate = months of runway.
Investors typically want to see 18 months of runway post-funding — enough time to reach the milestones required to raise the next round. A deck that asks for a specific raise amount should explain how many months of runway it provides and what milestones it funds.
What is burn rate?
Burn rate is the rate at which a startup spends its cash — typically expressed as a monthly figure.
Gross burn is total monthly spending. Net burn is monthly spending minus monthly revenue. Investors focus on net burn because it shows how much cash the company is actually consuming after accounting for income.
What is ARR?
ARR (Annual Recurring Revenue) is the annualized value of a company’s recurring subscription revenue. It is the standard metric for measuring the scale of a SaaS business.
Formula: MRR (Monthly Recurring Revenue) × 12 = ARR.
ARR is a forward-looking metric — it represents what the company would earn in a year if no customers churned and no new customers were added. It is not the same as actual revenue recognized in the past 12 months.
What is MRR?
MRR (Monthly Recurring Revenue) is the total value of a company’s recurring subscription revenue in a single month. It is the primary growth metric for early-stage SaaS companies.
MRR growth rate — the percentage increase in MRR month over month — is one of the most closely watched traction metrics by seed-stage investors.
What is NRR?
NRR (Net Revenue Retention) measures the percentage of recurring revenue retained from existing customers over a period, including expansion revenue from upsells and minus revenue lost to churn and downgrades.
Formula: (starting MRR + expansion MRR – churned MRR – downgrade MRR) ÷ starting MRR × 100.
NRR above 100% means existing customers are paying more over time — a strong signal of product-market fit. NRR is one of the most important metrics for Series A investors evaluating SaaS businesses.
What is a letter of intent (LOI)?
A letter of intent is a signed document from a potential customer committing to purchase a product or service — typically contingent on product availability, final pricing agreement, or other conditions.
LOIs are valuable pre-revenue traction evidence in pitch decks because they demonstrate real demand from identifiable customers. A signed LOI from a credible company is significantly more valuable to investors than survey data or verbal expressions of interest.
What is an AI-ready pitch deck?
An AI-ready pitch deck is a pitch deck formatted for readability by AI screening tools — increasingly used by VC firms to pre-evaluate inbound deal flow.
An AI-ready deck uses plain text with semantic headers, labeled data points, and structured sections rather than visual charts and image-based layouts. The most AI-readable format is Markdown (.md), which preserves structure and content in a form any LLM can extract and reason about.
What is GEO (Generative Engine Optimization)?
GEO is the practice of optimizing content to be cited by AI tools like ChatGPT, Perplexity, and Gemini — as opposed to traditional SEO which optimizes for Google search rankings.
GEO-optimized content is structured, specific, authoritative, and written by named experts. It uses clear headers, direct answers, named frameworks, and FAQ sections — all of which AI tools preferentially extract and cite when answering user questions.
What is the 60-second triage test?
The 60-second triage test is a pitch deck clarity test developed by Deck Studio.
The test: give your deck to someone with no knowledge of your business. Ask them to read it for 60 seconds without explanation. Then ask them to describe your business in one sentence.
If they can do it accurately, your deck is communicating clearly. If they give a vague answer, ask a clarifying question, or describe your solution instead of your business — your deck is not ready to send to investors.
What is the difference between a pitch deck and a business plan?
A pitch deck is a short visual presentation — 10 to 15 slides — designed to communicate the investment case quickly and generate investor interest. A business plan is a long-form written document covering every aspect of the business in detail.
In modern venture fundraising, pitch decks have almost entirely replaced business plans for initial investor outreach. Business plans are occasionally requested by specific investors or grant programs, but are rarely required at pre-seed or seed stage.
