The Series B pitch deck is not a longer version of your Series A deck. The questions are different, the bar is higher, and the slides investors fixate on have shifted.
This is a slide-by-slide walkthrough of the standard 14-slide structure, with what investors actually scrutinize at each one.
Slide 1 — Cover
What’s on it: Company name, tagline, “Series B” or “Series B led by [lead]” if you have a lead committed.
What investors scrutinize: The tagline. If it takes more than five seconds for them to understand what you do, you’ve lost momentum before slide two.
Slide 2 — The opening hook
What’s on it: One sentence stating what you do, who for, and the magnitude of the opportunity.
What investors scrutinize: Whether the framing is honest. Series B investors have heard 200 pitches. They can spot inflated TAM and vague “we’re the [Stripe/Shopify/Plaid] of X” framings instantly.
Slide 3 — The problem
What’s on it: The customer pain you solve, with specific evidence.
What investors scrutinize: Whether you can articulate the problem in your customer’s words, not yours. Specific quotes from customers, specific dollar amounts of pain, specific frequency of occurrence.
Slide 4 — The solution
What’s on it: Your product, ideally with a screenshot or short demo.
What investors scrutinize: Differentiation. By Series B, they assume the product works. The question is: why you and not the three competitors they’ve already seen this quarter?
Slide 5 — Traction
What’s on it: ARR, growth rate, customer count, logos (if shareable), key contract values.
What investors scrutinize: The shape of growth. A jagged growth line with explanations is more credible than a smooth hockey stick. Investors are looking for evidence that growth is reproducible, not just a moment in time.
Slide 6 — Business model & unit economics
What’s on it: Pricing, customer acquisition cost, payback period, gross margin, NDR.
What investors scrutinize: Whether the unit economics improve at scale. They’ll ask: at $50M ARR, what’s your CAC payback? What’s your gross margin? If you can’t show convincingly improving economics, the valuation conversation gets harder.
Slide 7 — Market
What’s on it: TAM, SAM, SOM (or your version of market sizing).
What investors scrutinize: Whether your bottoms-up math holds up. Top-down TAM (“the global X market is $400B”) gets dismissed immediately. Investors want bottoms-up: number of target customers × realistic ACV × penetration assumption.
Slide 8 — Competition
What’s on it: Competitive landscape, your position in it.
What investors scrutinize: Honesty about who you actually compete with. A 2x2 matrix that conveniently places you alone in the top-right quadrant signals you don’t understand the market.
Slide 9 — Go-to-market
What’s on it: How you acquire customers, which channels work, which are scaling.
What investors scrutinize: Channel concentration. If 80% of your revenue comes from one channel (especially paid acquisition or a single partnership), they’ll dig in. They want to see two or three scaling channels by Series B.
Slide 10 — Team
What’s on it: Founders, key executives, advisors, board.
What investors scrutinize: Specific roles you’ve filled vs. roles you’re missing. Series B investors expect you to have a VP Sales, VP Engineering, and a competent finance leader (CFO, fractional CFO, or VP Finance). Gaps need explanations.
Slide 11 — Financial summary
What’s on it: Historical and projected revenue, burn, runway, headcount.
What investors scrutinize: Whether your projections tie to your traction story. If you grew 80% last year and project 200% next year, you’d better explain the accelerant.
Slide 12 — Use of funds
What’s on it: How you’ll deploy the capital — hiring, product, GTM, etc.
What investors scrutinize: Whether the spend creates the milestones to justify the next round. They mentally do the math: “If they hit these milestones, can they raise a Series C at 2-3x this valuation?”
Slide 13 — The ask
What’s on it: Amount raising, target valuation range (sometimes), milestones to next round.
What investors scrutinize: Whether the ask matches the use of funds and runway math. Raising $20M with 24-month projected runway and ambitious hiring? That tracks. Raising $20M with 48-month projected runway? Why are you raising now?
Slide 14 — Vision
What’s on it: Where the company goes long-term.
What investors scrutinize: Whether the vision is large enough to justify a venture return. Series B investors need to believe this company can be worth $1B+ to make the math work for their fund.
What separates good decks from forgettable ones
Three things.
Specific numbers everywhere. “Strong growth” doesn’t land. “Grew from $2.4M to $8.1M ARR in the last 18 months while reducing CAC from $4,800 to $2,100” lands.
A coherent narrative. Each slide should set up the next one. Problem → solution → traction → unit economics → market → team. Every slide should feel inevitable given what came before.
No filler. Cut the “Why now” slide. Cut the customer logos slide if your logos don’t move the needle. Cut everything that doesn’t directly advance the case.
