From Seed Round to Stock Exchange — Understanding IPOs When You're Not a Finance Person

If you work in tech, you’ve probably had a recruiter pitch you equity in a pre-IPO startup. The numbers sound exciting until you realize you don’t actually understand what any of it means. This post breaks down the entire IPO pipeline — from how startups get funded to what happens to your stock options when the bell rings.

The Problem

IPOs sit at the intersection of finance, law, and corporate strategy — three domains that most engineers, developers, and architects never had to think about. When you receive an offer that includes “stock options” or “equity,” you’re expected to evaluate something you were never trained to evaluate.

The result? People either dismiss equity as “monopoly money” and leave significant value on the table, or overvalue it and make career decisions based on fantasy math. Neither is great.

What’s missing is a plain-language explanation of how the entire machine works — from the first dollar invested in a startup to the moment money lands in your bank account.

The Solution

Walk through the full lifecycle: how startups get funded, why IPOs happen, how valuations work, and what your equity is actually worth. No finance degree required.

The key insight upfront: an IPO isn’t some optional milestone that a company chooses on a whim. It’s a structural consequence of how venture capital works. Understanding that one fact changes how you evaluate every equity offer.

How It Works

Where the Money Comes From

Before a startup has customers or revenue, it needs money to build the product. That money comes from Venture Capital funds — firms that specialize in high-risk, high-reward investments.

But here’s the thing most people miss: VCs don’t invest their own money. They manage money from other people called Limited Partners (LPs) — pension funds, university endowments, family offices, insurance companies. Regular people’s retirement savings, channeled through institutional investors.

The deal between a VC and its LPs is simple:

“Give us $1 billion. We’ll invest it across 30-50 startups. In 10 years, we’ll give you back $3-5 billion.”

If the VC can’t deliver returns, no one will trust them with money again. Their business dies. This creates an inescapable clock — every investment must generate a return within the fund’s lifetime (typically 7-10 years).

This is why the question isn’t “will there be an IPO?” but “when will there be an exit?” VCs don’t have the option to hold forever.

How Startups Raise Money

A startup typically raises money in rounds, each bringing new investors and a higher valuation:

Round	Typical Valuation	What’s Proven	Risk Level
Seed	$5-50M	Team + idea	Very high (no product)
Series A	$50-500M	First product, early users	High (no revenue)
Series B/C	$500M-5B	Product-market fit, revenue growing	Medium
Pre-IPO	$5-20B	Scaled revenue, enterprise contracts	Medium-low
IPO	$10-50B+	Public market validates	Variable

Each round works the same way:

1. The startup needs cash to grow
2. An investor offers money in exchange for a percentage of the company
3. The valuation is a simple ratio: if an investor pays $100M for 10%, the company is “valued at $1B”

That valuation isn’t an objective truth — it’s what one buyer agreed to pay at one point in time. If market conditions change, the next round could be higher (up round) or lower (down round).

How Valuation Actually Works

When you hear “this company is worth $6 billion,” what does that mean? There’s no formula that spits out a number. But there are methods that investors use to arrive at one.

Method 1: Revenue multiple

This is the most common approach for high-growth tech companies.

Valuation = Annual Revenue × Multiple

The “multiple” depends on how fast the company is growing, how large its market is, and how much hype the sector carries:

Company Type	Typical Multiple	Why
Mature SaaS (10-20% growth)	8-15x	Predictable but slow
High-growth SaaS (50%+ growth)	15-30x	Fast growth justifies premium
AI frontier (2024-2026)	25-50x	Massive hype + huge market

A company making $200M/year with a 30x multiple = $6B valuation. Same company in a market crash with a 10x multiple = $2B. The revenue didn’t change — the market’s willingness to pay did.

What drives the multiple up:

• Revenue growth >50% year-over-year
• Large addressable market (TAM)
• Defensible moat (regulatory, network effects, switching costs)
• Recurring revenue (SaaS subscriptions)
• Net revenue retention >120% (customers spend more each year)

What drives it down:

• Slowing growth
• No path to profitability
• Commoditization (competitors offer the same thing)
• Market downturn or sector-wide correction

Method 2: Comparables

Look at similar public companies and apply their multiples. If three comparable companies trade at 20x revenue, your startup at a similar stage should be valued similarly.

Method 3: Last round price

The simplest: the company is worth what someone last paid. If Series B investors valued it at $6B, that’s the working number until the next round or IPO changes it.

The critical thing to understand: valuation is negotiated, not calculated. It’s the intersection of what sellers will accept and what buyers will pay, influenced by market conditions, competitive dynamics, and narrative.

Why IPOs Are (Almost) Inevitable

Remember the VC clock? Here’s how it plays out in practice.

Imagine a startup founded in 2023 with this investor timeline:

Investor	Entry Date	Fund Expires
Seed VC	2023	~2030-2033
Series A lead	Late 2023	~2030-2033
Series B lead	2024	~2031-2034

By 2028-2030, every investor is approaching the end of their fund lifecycle. They need to convert their paper ownership into real money. The pressure on the board becomes enormous.

The founders might want to stay private and independent. But investors who own 40-60% of the company have board seats and voting rights. When the fund clock runs out, one of three things happens:

1. IPO — preferred exit. Maximum valuation, controlled timing, founders retain some control.
2. Acquisition — a larger company buys the startup. Faster, more certain, but founders lose independence.
3. Secondary sale — investors sell their shares to other private investors. Partial liquidity, but not a full exit.

Option 4 — staying private indefinitely — is almost never viable because it leaves the investors stuck with paper they can’t convert.

The IPO Process

An IPO isn’t a single event. It’s a 12-18 month process:

T-18 months: Internal readiness

• Hire an IPO-experienced CFO
• Begin financial audits with a Big Four firm (you need 2-3 years of audited financials)
• Establish board committees (audit, compensation, governance)

T-12 months: Decision

• Board votes GO/NO-GO based on: revenue (>$500M ARR is typical), growth trajectory, market conditions, and team readiness
• Select investment banks to underwrite (they’ll manage the offering)

T-6 months: Prospectus filing

• File the S-1 (US) or prospectus (EU) with regulators
• Everything becomes public: revenue, losses, customers, risks, executive compensation
• Analysts and journalists dissect every number

T-3 months: Roadshow

• CEO and CFO tour institutional investors (pension funds, hedge funds) to pitch the company
• Investors indicate how many shares they’d buy and at what price
• This determines the IPO price range

T-1 month: Pricing

• Final IPO price is set (e.g., $45/share)
• Shares are allocated to institutional investors

Day 0: The bell rings

• Shares begin trading on the stock exchange
• The price fluctuates based on supply and demand
• Employees and early investors cannot sell — a lock-up period (typically 6 months) prevents insider selling

T+6 months: Lock-up expires

• Insiders can finally sell shares on the open market
• This is when your equity becomes real money

What Your Equity Is Actually Worth

When you join a pre-IPO startup, part of your compensation is equity — typically stock options (or their local equivalent). Here’s the lifecycle:

Step 1: Grant — The company gives you the right to buy shares at a fixed price (the “strike price”). This price is set based on the company’s current valuation. You don’t pay anything yet.

Step 2: Cliff — For the first 12 months, nothing vests. If you leave before the cliff, you walk away with zero equity. This protects the company from short-tenure employees.

Step 3: Vesting — After the cliff, 25% of your options vest immediately. The remaining 75% vest monthly over the next 3 years. After 4 years, you’re “fully vested.”

Step 4: Exercise — You “exercise” your options by paying the strike price out of pocket. If your strike price is $2/share and you have 10,000 options, you pay $20,000 to own 10,000 actual shares. Most people wait until near or after the IPO to exercise.

Step 5: IPO + Lock-up — The company goes public. Your shares are now theoretically tradeable — but the lock-up prevents you from selling for ~6 months.

Step 6: Sell — Lock-up expires. You sell shares on the stock exchange. Money hits your bank account. This is the only moment that generates real, spendable money. Everything before this is paper value.

The formula is straightforward:

Your gain = (Market price - Strike price) × Number of vested shares

If the market price is $40, your strike price was $2, and you have 7,500 vested shares:

• Gain = ($40 - $2) × 7,500 = $285,000 before taxes

The Revenue Multiple Is the Invisible Hand

Your equity value depends on exactly four things:

Your payout = Company revenue × Market multiple × Your % ownership - Taxes

You control one of these: your percentage (negotiated at hiring). The other three — revenue, multiple, and tax rates — are outside your control.

This is why equity negotiation matters more than base salary negotiation when joining a pre-IPO startup. The difference between owning 0.01% and 0.02% at a $20B IPO is roughly $1M after taxes. That’s 10x more impactful than a $5K bump in base salary.

What to Negotiate (and What to Ask)

When evaluating an equity offer, these are the questions that matter:

Question	Why It Matters
What percentage of the company does my grant represent on a fully diluted basis?	The number of shares is meaningless without context. 10,000 shares out of 500 million = 0.002%
What is the current strike price?	Based on the latest valuation or a formal assessment
What is the vesting schedule?	4 years with 1-year cliff is standard. Anything else, negotiate.
Is there a secondary liquidity mechanism before IPO?	Some companies allow early share sales on private markets
What’s the board’s target timeline for an IPO or exit?	Helps you estimate when paper value becomes real
What dilution has occurred since the last funding round?	Each new round dilutes existing shareholders

Paper Value vs. Real Money

This is the most important distinction in startup equity. Until an exit event (IPO or acquisition), your equity is paper. You cannot spend it, borrow against it easily, or convert it to cash.

Compare this to public company stock (like RSUs from a large tech company):

	Public Company RSUs	Pre-IPO Stock Options
Liquidity	Sell anytime on the stock exchange	Cannot sell until IPO or acquisition
Risk	Low (established company)	Medium-high (startup may fail)
Upside	Limited (~10-15%/year for big tech)	Potentially 3-10x if IPO succeeds
Certainty	Known value (stock price is public)	Unknown until exit
Tax timing	Taxed at vesting (treated as salary)	Taxed at sale (often at lower rates)

The trade-off is clear: predictable and liquid vs. uncertain but potentially massive. Neither is objectively better — it depends on your risk tolerance, financial situation, and belief in the company.

The Scenarios That Matter

When evaluating an equity offer, model three scenarios:

Optimistic (30-40% probability): IPO at 3-4x the current valuation. Your options are worth several multiples of your annual salary. The career bet paid off spectacularly.

Base case (30-40% probability): IPO or acquisition at 1.5-2x current valuation. Your options are worth a meaningful but not life-changing amount. The career move was still positive.

Pessimistic (20-30% probability): No exit, or exit below your strike price. Your options are worth zero in practice. But you gained experience and skills that are transferable.

The asymmetry is what makes pre-IPO equity attractive: in the worst case, you gained career capital. In the best case, you gained financial capital that would have taken decades to accumulate through salary alone.

France-Specific: BSPCE — The Tax Advantage

If you’re joining a French startup, your equity likely comes as BSPCE (Bons de Souscription de Parts de Créateur d’Entreprise) rather than US-style stock options. The French government created this mechanism specifically to make startup equity more attractive.

How BSPCE differ from standard stock options:

Event	Standard Stock Options	BSPCE (France)
Grant	No tax	No tax
Vesting	May be taxed as income (US RSUs)	No tax
Exercise	May trigger AMT (US)	No tax
Sale	Capital gains tax	Flat tax 30% (if 3+ years tenure)

The key advantage: BSPCE are only taxed at the moment of sale, and at a flat 30% rate (12.8% income tax + 17.2% social contributions) if you’ve been with the company for at least 3 years.

Compare this to regular salary or RSU taxation in France, which can reach 40-50% through the progressive income tax brackets plus social charges. On a $1M gain, that’s a $100-200K difference.

The 3-year rule is critical:

• Sell before 3 years of tenure → taxed as salary (progressive brackets, 40-50%)
• Sell after 3 years of tenure → flat 30% PFU (Prélèvement Forfaitaire Unique)

If you join in April 2026 and the IPO happens in late 2028, the 6-month lock-up period actually works in your favor — by the time you can sell (mid-2029), you’ve passed the 3-year threshold. The lock-up effectively protects you from selling at the wrong tax rate.

Strategy: If the lock-up expires just before your 3-year anniversary, wait a few weeks. The tax savings on a large gain far outweigh the risk of a short-term price fluctuation.

What I Learned

• IPOs aren’t optional — they’re a structural consequence of the VC funding model. VCs must return money to their LPs within 7-10 years, making an exit event (IPO or acquisition) nearly inevitable for well-funded startups.

• The multiple matters more than the revenue — a company’s valuation is revenue times a market multiple. That multiple can swing from 15x to 50x based on growth, hype, and market conditions. The same company can be “worth” $3B or $10B depending on when you ask.

• Negotiate the percentage, not the share count — “10,000 shares” means nothing without knowing the total. Always ask for your percentage on a fully diluted basis. The difference between 0.01% and 0.02% at a $20B exit is roughly $1M after taxes.

• Paper value isn’t real value — until an IPO or acquisition happens and the lock-up expires, your equity is theoretical. Make sure your base salary is livable without counting on equity. Think of equity as a bonus outcome, not guaranteed compensation.

• Tax timing is a lever you control — especially in jurisdictions like France where BSPCE are taxed at sale (not at vesting), and where holding periods unlock lower tax rates. Understanding the rules can save you hundreds of thousands on a large gain.

What’s Next

• When evaluating your next offer, build a 3-scenario model (optimistic/base/pessimistic) for the equity component
• Ask the six questions from the negotiation section before signing anything with an equity component
• If you’re in France, consult a tax advisor specializing in BSPCE before exercising or selling — the rules are favorable but the details matter
