Hey {{first_name}} 👋, first things first - I finally moved to Valencia, Spain. I have big plans for you, stay tuned! I hope you’re having a great week! In the last issue, we discussed why tracking NRR benchmarks matter, and now we are moving with the next topic from Reporting content.

Let’s talk about ⬇️

Most seed-stage founders I work with make the same mistake.

They build a financial model that looks impressive in a spreadsheet, attach it to a deck, and call it investor-ready.

Then the first serious investor asks a single question — "How did you arrive at this revenue number?" — and the room goes quiet.

Here's the thing seed founders consistently misunderstand: your projections aren't about predicting the future with precision. No one expects you to nail month-18 ARR to the dollar. What investors are actually evaluating is your thinking — whether you understand the drivers of your business, whether your assumptions are internally consistent, and whether you've pressure-tested the numbers well enough to defend them under fire.

And in 2026, with the seed bar higher than it's ever been, this matters more than ever.

Today I'm walking you through exactly what a fundable seed model contains, the benchmarks that actually apply right now, and the mistakes that kill deals before due diligence even starts.

Let's dig in:

1️⃣ Why Seed Projections Are Fundamentally Different

2️⃣ The Five Components of a Fundable Seed Model

3️⃣ Revenue Forecasting: Bottom-Up Always Beats Top-Down

4️⃣ Scenario Modeling Done Right

5️⃣ Burn Rate, Runway, and Cash Flow Planning

6️⃣ Unit Economics Your Model Must Reflect

7️⃣ The 2026 Benchmarks Investors Are Actually Using

At Series A and beyond, investors have data — 12+ months of cohorts, churn curves, sales cycle lengths, payback periods. They can scrutinize actuals.

At seed, that data is thin or non-existent. Which means your model has to do heavier narrative work than most founders expect.

Seed investors aren't modeling your business from first principles. They're stress-testing your understanding of it. A model built on aggressive top-down assumptions — "If we capture just 1% of a $10B market…" — tells an investor nothing useful. It actually signals the opposite of sophistication.

What works is bottom-up, anchored in honest inputs: how many salespeople you'll hire, at what ramp time, with what quota capacity. Or for PLG businesses: activation rate, conversion to paid, expansion MRR. The numbers that come out the other end matter less than the inputs being defensible.

The 2026 market makes this non-negotiable. Seed funding has bifurcated sharply — deal volume is down meaningfully from peak years, but the rounds that do close are bigger and going to companies that can demonstrate financial command, not just a compelling story. The middle is thinning. The barbell is real: top-tier companies with traction raise $3–5M at premium valuations, while many others struggle to close any round at all.

Most models I see in the wild are missing at least two of these:

1. Assumptions tab. The most important sheet — and the one most founders skip. Every input driver (ACV, sales headcount ramp, churn rate, gross margin, cost per lead) should live here, exposed and labeled. When an investor asks "Why is your churn 2%?", you point directly to a cell and explain the reasoning.

2. Revenue model. Your top-line build. For SaaS, model revenue as a function of new logos per month, average ACV, expansion MRR rate, and gross revenue churn. For marketplaces, model GMV, take rate, and transaction volume separately. Never lump everything into a single "revenue growth %" line.

3. Headcount and OpEx model. Hiring is the single biggest driver of seed-stage burn. Model headcount by role and month, with fully loaded costs (salary, payroll taxes, benefits). For engineering and product hires, include a ramp period before full productivity. This burdened-labor-rate approach is the difference between a model that holds up and one that collapses the moment an investor runs the numbers.

4. Three-statement model. Even at seed, you need a projected income statement, balance sheet, and cash flow statement. Many founders show only a P&L. That's a red flag — cash flow is what actually determines survival, and investors know it.

5. Scenario analysis. Three scenarios: conservative, base, aggressive. Show how each changes your runway and key metrics.

The story that proves the point: In one seed round, a founder won the meeting on a single assumption — their CAC payback. The model showed 9-month payback. What made it credible wasn't the number; it was that it was backed by 8 months of actual cohort data from a paid pilot with 12 customers, attached as a supporting tab. The lead investor spent forty minutes on that one tab. The round closed two weeks later at a valuation 30% above the initial anchor.

The lesson isn't that 9 months is magic. It's that a well-supported assumption with real data behind it beats an optimistic projection with a clean formula — every time.

Ready to level up your finances?

The top-down approach — "our TAM is $5B and we'll get 0.5% of it" — is not a financial model. It's a marketing slide disguised as a number. I've seen it in hundreds of decks, and it signals, every single time, that the founder hasn't done the hard thinking.

Bottom-up means building your revenue from operational inputs:

Build those month by month for 18–24 months, and your revenue projection falls out as the mathematical result. This forces disciplined GTM thinking, surfaces bottlenecks before they happen, and gives investors something real to evaluate.

The single input founders get wrong most: time to first revenue from a new sales hire. Founders almost universally model new AEs as productive from month two or three. The actual number is closer to month five or six for any B2B SaaS product with a real sales motion.

When you compare seed projections to actuals at 12 months, the revenue shortfall almost always traces back to this one input. The hire happened on schedule. The ramp did not. A founder who modeled three AEs productive at month two — and actually saw them productive at month six — has lost four months of productive selling across the whole team. That gap rarely closes within the model period.

The single-scenario model is one of the biggest trust killers in a seed pitch. Present one set of projections as "the forecast" and you're either overconfident or you haven't tested your own assumptions. Investors know this.

A credible scenario analysis gives you three distinct MRR trajectories — each driven by genuinely different input assumptions, not a percentage adjustment to the same base.

The conservative case is not "base minus 20%." It reflects a genuinely different growth rate, a longer sales cycle, or higher churn. The aggressive case reflects what happens if your second sales hire ramps faster than expected and retention beats benchmark.

The gap between the scenarios is the conversation. An investor will ask: "What would it take to hit the aggressive case? What does the conservative case tell you about your minimum viable GTM motion?" Those are exactly the questions you want to be having.

If there's one number a seed investor cares about above all others, it's runway — how long the company survives on the capital raised, and whether the plan hits meaningful milestones before the clock expires.

Here's where the 2026 environment changes the math dramatically: the seed-to-Series A timeline has stretched to roughly 616 days — over two years. And the Series A bar has risen sharply. What needed $1–3M ARR two years ago now needs $5–10M ARR with 150%+ growth.

That means your seed round has to fund the company long enough to clear a much higher Series A bar than founders raising in 2022 faced. A round giving you 12 months of runway isn't remotely enough.

Practical runway rules for 2026:

The biggest burn-modeling error: using a flat monthly burn number for the entire period. Burn is not flat — it ramps as you hire. Project $150K/month in month 1 and model that flat for 18 months, and you're misrepresenting both your hiring plan and your actual out-month cash position.

Even at seed, unit economics need to be in the model. Investors aren't asking for perfect data — they're asking for a framework that proves you understand what drives profitability at scale.

CAC. Total sales and marketing spend divided by new customers acquired. At seed you may not have months of data, but you should have a cost-per-lead estimate and a conversion assumption. Model it explicitly — don't hide it.

LTV and LTV:CAC. LTV = (ARPU × Gross Margin) ÷ Churn Rate. The target ratio for most SaaS is 3:1 or higher. Improving LTV:CAC from 2x to 3x can nearly triple your valuation — higher margins compound into higher reinvestment capacity and higher multiples. Show where you start and where you expect to land by month 18.

CAC payback period. How many months of subscription revenue it takes to recover acquisition cost. The 2026 benchmark: under 12 months for direct sales, under 6 months for PLG. A 24-month payback isn't an automatic deal-killer — but you need to explain the logic and the path to improving it.

The current seed market rewards specificity. Investors no longer accept top-of-funnel TAM arguments as a substitute for operational clarity. Here's what the 2026 data actually shows:

These aren't targets to hit artificially. They're reference points for where your business sits relative to the cohort investors are evaluating simultaneously.

One more 2026 reality worth naming: founders who burned a pre-seed ($500K–$1.5M) without reaching clear product-market-fit signals — loosely, 5–10 paying customers who renew and refer — face valuation compression at seed. Investors price in the burn history and discount forward ARR estimates accordingly.

Seed round financial projections are one of the highest-leverage documents you'll produce as a founder. Done right, they signal operational maturity, force honest thinking about your GTM assumptions, and give investors a clear basis for belief. Done wrong, they erode trust faster than almost anything else in the process.

The fundamentals aren't complicated:

Build bottom-up. Expose your assumptions. Model three scenarios. Show unit economics even when they're early. Plan for 24 months of runway. Make the model trace directly to the story you tell in the room.

The founders who close seed rounds in 2026's tighter market aren't the ones with the most optimistic spreadsheets. They're the ones who can walk an investor through the logic of their business — calmly, specifically, and without flinching when the hard questions come.

Your projections aren't a fundraising artifact. They're the operating system of your business for the next 24 months — a living tool you update as actuals come in.

Get the model right before you walk into the room.
