Fundraising for SaaS Startups

This piece belongs to the ongoing Founders Guide—a collection of notes I’m assembling for first-year founders while the memories of my own missteps are still fresh.

The first invoice that hit my desk when we started mindnow was for desks—second-hand IKEA, CHF 170 each if you’re curious. The next one was the lawyer retainer, which instantly dwarfed the desks. Point is, cash leaves the building long before revenue walks in, even for “lightweight” SaaS. Some founders keep a coffee-can fund precisely for that moment; others, myself included, discover the can is half empty (or missing altogether).

So, do you raise or do you bootstrap? Both paths have respectable alumni—37signals kept full control and built a profit machine, while Calendly took funding later and scaled faster than my caffeine intake during launch week. I lean neither way dogmatically. Money is a tool, not a status flag. If outside capital helps you reach default-alive sooner, consider it. If you can grow on customer revenue alone, you’ve just bought yourself optionality (and fewer shareholder updates).

This write-up won’t cover every obscure term sheet clause. It’s a field guide—what I’ve seen from sitting on both sides of the table, plus a few numbers I keep scribbled on the whiteboard in our Zurich office.

When should you fundraise?

Investors open the spreadsheet—rarely the checkbook—when they can picture your product, market, and traction in under five minutes. That means you’ve answered three questions: Who needs this badly enough to pay? How do you reach them? And why are you the team to pull it off? Miss one and the meeting turns into polite nods.

Stories help, but stories alone don’t clear due diligence. I’ve watched pitch decks that started with a moving founder journey and ended with churn north of 15%—nobody remembers the story at that point. Low churn rates are often expected for Series A conversations (I could be wrong, but it’s what crossed my inbox most of 2021).

If you already generate real revenue, fundraising becomes a timing game: raise when capital can accelerate what’s working, not resuscitate what isn’t. I’ve passed on deals that looked like a last-minute oxygen tank. Doesn’t mean they can’t turn around, but the odds aren’t in their favour.

Bottom line: clarify the why and how first, then think about term sheets. Skip the sequence and you’ll join the Slack channel of “I wish we’d raised earlier” founders.

How much should you raise?

The naïve answer is “as much as they’ll give you.” The practical answer: enough to get you 12–18 months of runway with measurable milestones—normally ARR growth or usage—so you don’t crawl back to the market hat in hand. Those milestones differ by sector; robotics teams I talk to burn through that same cash in half the time just buying components. SaaS is friendlier.

I start with burn: three engineers at CHF 10k each, plus cloud, plus the unavoidable Notion/Slack/Linear subscriptions—call it CHF 45k monthly. Eighteen months means roughly CHF 810k. Round to a number investors recognise and you land somewhere around $500k to $1.5m for a seed round. Could be less if you’re profitable, could be more if you’re tackling enterprise sales (hello, 9-month cycles).

• Progress – Ask how far CHF 1m really gets you. A live product? 1,000 paying users? If the answer is only “beta launch,” adjust.
• Credibility – Prior usage of funds matters. If your dashboard shows net revenue growth and churn below 5% monthly, every conversation gets easier.
• Dilution – Play with scenarios before talking numbers. I keep an online dilution simulator bookmarked; drop in 10% vs. 20% and watch what that means three rounds later. Sobering stuff.

I try to cap seed dilution at 15–20%. Push past 25% and you’ll feel it when you’re negotiating stock options for early hires (been there, spent the weekend untangling the math).

There are different fundraising methods to consider

One founder swears by safes, another by equity, a third bootstraps till $1m ARR then opens a debt line. None of them are wrong. They’re optimising for different constraints: speed, control, or simplicity.

You can absolutely self-educate with open-source cap-table templates and save the legal bills for later (I did for the first months). Still, once real money is involved, a lawyer who’s seen a few hundred deals is insurance, not luxury—just maybe don’t hire a fractional CFO when there’s barely a fraction to chief over.

Quick refresher before we get to the instruments: venture rounds come in letters—Seed, A, B, C—each with its own yardstick. Seed is increasingly done via safes or convertible notes; Series A onward drifts toward priced equity.

Getting Convertible Debt

A convertible note is a loan that mutates into equity during the next priced round. It carries interest (usually 4–8%) and a maturity date. The sweeteners are the discount (say, 20% cheaper shares) and the cap (ceiling on valuation for note holders). Nice for speed; less nice if you forget the maturity date and the note comes due in the middle of Christmas break.

Pro tip I learned the hard way: keep a cash buffer for note repayment even if you’re sure the next round will close in time. Murphy’s law respects no term sheet.

Safe

The safe (thanks, YC) ditches interest and maturity dates. Negotiation boils down to amount, discount, and cap. Cleaner paper, faster close. Just remember: multiple safes with different caps stack up—your cap table can look like a game of Tetris by Series A.

Splitting Equity

Equity rounds price the company today, issue new shares, and dilute everyone proportionally. More work, more legal fees, but also more certainty—no surprise conversions down the road.

Run the math with simple numbers: pre-money $10m, raise $2m, that’s $12m post-money, roughly 16–17% dilution. Same logic holds whether zeros are bigger or smaller.

1. $10,000,000 / 20,000,000 = $0.50 per share
2. You sell 4,000,000 shares
3. Total shares: 24,000,000
4. Post-money valuation: $0.50 × 24,000,000 = $12,000,000
5. Dilution: 4,000,000 / 24,000,000 ≈ 16.7%

That’s the clean version. Real rounds layer in liquidation preferences, pro-rata rights, maybe an ESOP top-up. Read every clause; I got this wrong once and spent weeks renegotiating.

Valuation

SaaS has no factories to count, so valuation is mostly narrative plus metrics. Stick rate, net dollar retention, and month-over-month growth matter more than vanity users. Benchmark peers—B2B SaaS at $1m ARR and 10% monthly growth often lands within a typical industry range, at least in 2022. Could shift by the time you read this.

Going to Investors

Angel, super-angel, micro-VC, mega-fund—the taxonomy expands yearly. Angels move fast but write smaller cheques; VCs take their time, bring a playbook, and want board seats. Match your needs. If all you need is runway to iterate, an angel bridge might beat a million-line diligence spreadsheet.

Whatever the label, the people behind the money are what count. Investors who obsess over retention will grill you on cohort charts; growth-at-all-costs funds care less. Do your homework—Crunchbase plus a bit of Linkedin stalking goes a long way.

Relationships precede wire transfers. Warm intros work because trust is borrowed. When that fails, thoughtful cold emails still land meetings—keep them under 150 words and request a call, not a cheque.

Crowdfunding

Crowdfunding platforms are half marketing, half fundraising. Great if your product resonates with early adopters; risky if you’re B2B SaaS and your customer is a CFO, not a backer hunting for the next smart gadget. I treat it as a visibility channel, not a primary funding plan.

Fundraising comes in steps

No magic form unlocks capital overnight. Plan for a process: prep, pitch, follow-ups, negotiation. I underestimated the calendar time—our first seed round took eleven weeks from first email to money-in-bank. Could be faster, could be slower; holidays and market dips don’t care about your burn chart.

Gathering documents

At minimum: one-pager, deck, light data room. Skip the 40-slide novel—10–12 slides are plenty. Executive summary should answer vision, market, traction, team, ask. Charts beat adjectives.

If an investor demands five-year GAAP projections before you have a product, consider whether they invest in your stage at all. Most seed funds I meet accept short-form financials (again, churn and retention trump line-by-line budgets).

Meeting the investors

First meeting is about intrigue, not closure. Tailor the story to the partner’s thesis—yes, that means reading their last Medium post. Listen more than you talk; questions reveal what they care about. I jot them down right after the call for the inevitable follow-up deck tweak.

Confidence sells, bravado repels. I still rehearse the opener out loud the morning of the pitch—it knocks out 80% of the ums.

Closing the deal

Seed rounds close fastest when you stick to industry-standard docs—YC safes, NVCA terms, whatever matches your jurisdiction. Deviate and lawyers get involved, clocks start ticking, momentum leaks.

Verbal commitment? Lock it with a handshake memo the same day (email counts). I lost a would-be lead who drifted because we “circle back next week.” Never again.

Advice for proper fundraising

Have a technical co-founder

Investors bet on teams. A hacker–hustler combo still plays well. Solo founders succeed, but every diligence call will start with “When will you bring in a technical lead?” Spare yourself the loop.

Look for warm intros

Map funds, define criteria—cheque size, domain, stage—then search LinkedIn for mutuals. Offer value first: feedback, beta access, anything that isn’t “invest please.”

When a warm intro isn’t on the table, turn to cold emails

Subject line: “Seed round for <problem>—ARR $25k, churn 3%”. Body: two sentences on pain, one on traction, call-to-action for a 15-minute chat. Works more often than you’d think.

Next Steps

Fundraising is optional, not mandatory. If you choose it, treat it as a sprint with a clear finish line: capital in the bank, heads down building again. And remember—term sheets fade, but retention and product-market fit keep the lights on.
